View on Amazon

Making a decision on our top pick was a breeze. After thoroughly testing the Anker PowerCore 20100 power bank at Creative Bloq, we are confident that it currently stands as the best power bank you can purchase.

When it comes to charging speed, connectivity, and price, it is undoubtedly unparalleled. Sporting a generous battery capacity of 20,100mAh, you can expect multiple charges before needing to recharge the power bank itself.

Elegantly slim and sleek, the Anker PowerCore 20100 power bank boasts the ability to charge two devices simultaneously through its two 2.4 Amp USB ports. What’s even better is that if your devices are equipped with PowerIQ or VoltageBoost technology, it will charge them even faster. The ultimate testament to its performance lies in our writer’s experience – after trying it out for a while, they were so impressed that they ended up purchasing one for themselves.

2.Charmast Portable Charger

View on Amazon

At one point, power banks with LCD displays used to be quite pricey, but now, even affordable models like this one are equipped with them, thanks to the declining prices.

This power bank stands out with its three outputs, making it highly convenient for charging multiple devices simultaneously. It features two full-size USB ports and a versatile USB-C PD port, which can serve as both an input and output. All three ports support 18W Quick Charge, though only one can be used at a time.

On the side, you’ll find an additional Quick Charge 2.0-compatible Micro-USB port, which can also be utilized to charge the power bank itself. It takes around 3.5 hours to charge with a Quick Charge/PD adapter, but approximately 5.5 hours with a standard 10W charger.

One drawback of its design is that it’s slightly larger than many of the super-slim power banks with similar capacity available in the market. This Charmast power bank has roughly the same width as a phone, but it’s a bit shorter and noticeably chunkier. It weighs 228g, making it better suited for carrying in a bag rather than your pocket.To add to its appeal, Charmast provides a soft mesh carry case and a short USB-A to USB-C cable in the package, a thoughtful inclusion indeed.

3.imuto 100W Laptop Power Bank

View on Amazon

Offering mostly everything you could need at this price, the iMuto 20,000mah power bank has a 20,000mAh capacity that means you can charge the average smartphone over four times without a problem. The price is that it’s a fairly bulky power bank and it’s certainly heavy but with two ports and a screen that shows you how much charge is remaining, it’s certainly practical if not particularly portable.

4.Anker Portable Charger, 313 Power Bank

View on Amazon

Our second-ranked pick (still considered one of the best portable chargers) is the Anker PowerCore Slim 10000, which is slightly heavier than the INIU 10000 pack (7.3 ounces compared to 6.9 ounces). However, it could have claimed the top spot if it had an additional USB-A output port.

The charging times of the Anker PowerCore Slim 10000 were remarkably close to the INIU brick (21% in 15 minutes, 76% in an hour), and it took only 4 minutes less to fully charge an iPhone 12, totaling 1 hour and 56 minutes.

While it came very close to the INIU in performance, we have to keep it at the second rank due to minor differences. The performance of these chargers is so similar that they practically fall within the margins of error during testing. If you only need to charge one device at a time and find the Anker PowerCore Slim 10000 available at a more budget-friendly price compared to the INIU, it’s a great choice.

This product has garnered nearly 50,000 reviews on Amazon and holds an impressive rating of 4.6 out of 5 stars. A satisfied 5-star reviewer expressed their appreciation, stating:

“I appreciate the solid and sleek construction. It easily fits in my pocket. Most importantly, it delivers fast charging and has enough capacity to charge my phone multiple times over multiple days. It has also withstood plenty of accidental drops and awkwardly yanked cords without any issues.”

5.INIU Portable Charger

View on Amazon

USB-C is no longer just the port of the future; it has become the port of the present. Despite INIU’s 20-watt brick being slightly heavier (the second heaviest on this list), its dual-function USB-C port makes it a top contender for one of the best portable chargers, especially for those who rely on the reversible port. With this feature, you can charge the power bank and other devices using the same USB-C cables. Additionally, the power bank boasts two other USB-A ports for recharging other devices simultaneously.

Moreover, it excels in the 1-hour charging window, managing to bring a dead iPhone 12 to an impressive 81% of its charge. Its overall charging time of 1 hour and 57 minutes to fully charge the iPhone is the second-best among the pack, lagging behind the PowerCore Slim 10000 by only a minute. Another advantage lies in its substantial 20000 mAh capacity, enabling it to refuel an iPhone more times than most other chargers, providing an impressive 4.78 iPhone 12 refills.

This product has garnered nearly 4,500 reviews on Amazon with an impressive rating of 4.6 out of 5 stars. A satisfied 5-star reviewer shared their experience, stating: “During my 5-day vacation, I relied on this power bank to charge my phone and GoPro, and it still had 44% of its battery life left!”

6.Portable Charger Power Bank 25800mAh

View on Amazon

We approach no-name brands on Amazon with skepticism, and unfortunately, the Ekrist power bank (unlike the INIU power banks) confirms our suspicions. Although it does have a couple of positive features, such as a 25,800mAh power supply that can recharge our iPhone 12 four times and being 1.4 ounces lighter than the 20,000mAh INIU portable charger, there are other larger chargers with more impressive capacities that you should consider instead.

However, its downsides are quite apparent. Firstly, it lacks a USB-C input or output, which can be a significant limitation for many users. Moreover, our testing revealed slow charging performance, with disappointing scores on the 15-minute and 1-hour windows (17% and 72%, respectively). Furthermore, it took one of the longest times to charge an iPhone 12 from dead to 100% – a lengthy 2 hours and 21 minutes. It would have ranked last if not for the Miady discount double.

With over 29,000 customer reviews on Amazon, this charger has achieved an overall rating of 4.5 out of 5 stars. A satisfied 5-star reviewer shared their experience, stating, “I can honestly say that it is charging my phone right now while writing this review. Great product.”

7.EXCITRUS Wireless Portable Charger

View on Amazon

When it comes to charging your iPhone and other gadgets, the Excitrus PDW100208 is the ultimate all-in-one solution, earning it our top spot as the number one choice overall.

This power bank comes equipped with a 10W MagSafe pad, allowing you to wirelessly charge your iPhone with ease. In addition to that, it features a powerful 100W USB-C port, a 45W USB-C port, and an 18W USB-A port. With this impressive range of ports, you can charge up to four devices simultaneously. Moreover, the Excitrus PDW100208 can even be charged itself using the 100W USB-C port and the included USB-C to USB-C cable.

While it is a bit heavy, weighing just over half a kilo, and its long shape may feel a bit awkward, our reviewer found that it performed brilliantly in real-world usage. Furthermore, it offers a substantial capacity via its wired ports, making it more than sufficient to keep your laptops, cameras, and other devices running while you’re on the move, in addition to charging your iPhone. With its versatility and powerful charging capabilities, the Excitrus PDW100208 truly stands out as the ultimate charging companion.

8.Anker PowerCore Solar 20000

View on Amazon

Costing just over $50, Anker’s solar-powered 20,000mAh power bank features separate USB-A and USB-C inputs. The USB-C port works at up to 18W to recharge your capable devices in a hurry.

While there are only two total ports on the Anker 20,000mAh power bank, it recharges with the power of the sun so you can get back to 100% as you go about your day. Even better, the battery pack features added drop protection in all four corners, and the IP65 rating is good against splashes and dust.

Pros

  • AC outlet means this power bank can handle a wider range of devices than USB-A and USB-C ports alone
  • Fast charging time with the provided wall charger
  • Built-in flashlight
  • About the size of a paperback book

Cons

  • Display was less intuitive to use than the Scosche PowerUp 32K

When it comes to power banks for camping, striking the right balance is crucial. We want to disconnect from the grid, but we also need a bit of it to accompany us on our camping adventures—for air pumps, lanterns, and of course, our phones. While the smaller, smartphone-sized power banks fall short in meeting our extended power needs (especially when sharing with a loved one for more than three days), it can be tempting to upgrade to a massive power bank that resembles a home generator. However, this might defeat the purpose of getting off the grid altogether.

Enter the Anker 511 Portable Powerstation—a perfect middle ground for your power requirements. It offers enough juice to keep your phone charged without tempting you to indulge in excessive streaming or power consumption while enjoying the serene campfire ambiance. The power station’s size strikes the right balance, allowing for some extras, such as a handy flashlight and an AC outlet—features I didn’t even know I’d want until I reached the campsite. Despite these additional capabilities, it remains compact enough that you won’t struggle to fit it with all your other camping gear in the car.

One minor improvement could be the addition of a digital display to show the remaining power more precisely, rather than relying on a modified version of the light bars found on smaller power banks. Nevertheless, the Anker 511 still provided the information I needed—the assurance that there was ample juice left in the power bank to sustain my trip.

10.Anker 733 Power Bank

View on Amazon

You no longer have to choose between a great charger and a great power bank, nor do you need to spend twice the amount to get both. The Anker 733 Power Bank takes care of all your charging needs in one convenient device. At first glance, it appears to be a regular charger, and it performs exceptionally well in that role. It boasts the capability to charge three devices simultaneously at up to 65W, thanks to its combination of USB-C and USB-A ports.

What sets it apart is its integrated 10,000mAh battery. This innovative feature allows you to detach it from the wall and take it on the go, continuing to charge your devices even when it’s disconnected from the power source. This versatility makes the Anker 733 Power Bank a practical and efficient charging solution for all your devices.

What is a power bank?

A power bank is a portable electronic device designed to transfer power from its internal battery to other devices. This power transfer is commonly achieved through USB-A or USB-C ports, although wireless charging options are becoming more prevalent. The primary purpose of power banks is to charge small devices equipped with USB ports, such as smartphones, tablets, and Chromebooks. However, they are also capable of replenishing various USB-powered accessories, including headphones, Bluetooth speakers, lights, fans, and camera batteries.

To recharge the power bank itself, most models utilize a USB power supply. Some power banks offer a convenient feature called passthrough charging, allowing users to charge their devices while simultaneously recharging the power bank. This feature ensures uninterrupted power supply to connected devices, even when the power bank’s battery is being replenished.

How To Choose The Best Powerbank For Your Mobile Phone

Technology has been developing at a rapid rate recently. Nowadays we have social media, organizer, entertainment, academic, creative apps and much more all at the palm of our hands. No wonder we always want to roam around with these smart devices wherever we go. However, there is one problem that the rapid growth of technology hasn’t been able to solve – battery life. Interestingly, more features a phone has, more someone wants to use it, and faster its battery drains. This is where the power banks come in.

Features you should check before buying a powerbank

1. Battery Capacity

When considering a power bank, the first and foremost aspect that comes to mind is its capacity. Power bank capacity is measured in Milliampere Hours (mAh), which is indicated on any battery. The higher the capacity of the power bank, the more times it can charge your mobile phone or tablet.

For the best experience, it is recommended to choose a power bank with a capacity higher than the actual capacity of your phone’s battery. For example, if your phone has a 2500mAh battery, aim for a power bank with a minimum capacity of 5000mAh. This ensures that your phone can be charged at least twice. To account for minor energy losses during charging, consider going a bit higher, around 6000mAh.

While this guideline makes sense, it is essential to take your own usage patterns into account. If you are always close to a charging port and rarely find yourself away for extended periods, there’s no need to spend on a high-capacity power bank. Avoid purchasing power banks with capacities lower than 2000mAh unless you specifically require an ultra-compact option and do not frequently find yourself away from charging ports for long durations.

2. Manufacturer

Another essential consideration is the manufacturer of the power bank. Some readers may prioritize the battery technology used, but in reality, the manufacturer can make a significant difference in the product’s performance.

Reputable companies are more likely to offer higher-quality products compared to cheaper brands that focus solely on providing products at extremely low prices. Well-established brands tend to use superior components, making their power banks more reliable.

Considering the relatively high cost of mobile phones, it is advisable to connect them to a power bank manufactured by a trusted company.

The debate between lithium-ion and lithium-polymer batteries persists, but both types of batteries generally deliver similar performance. For the average user, distinguishing between the two may be challenging. Some power bank users believe that lithium-ion batteries may be safer than lithium-polymer batteries, but this ultimately depends on the safety measures taken by the manufacturer.

Therefore, it is crucial to choose a reputable company that guarantees a high-quality product, even if it means paying a little more. Opting for a cheaper, lower-quality power bank may lead to damage to your phone in the long run.

3. Connectivity Options and Number of USB Ports

The more connectivity options your power bank offers, the better it is. Power banks serve as essential tools during emergencies, and since they may be used with various devices, they should be compatible with all standard gadgets and capable of charging them within a reasonable timeframe.

Imagine switching from an iPhone to a Samsung device and finding out that your power bank doesn’t support your new Samsung phone. In such a scenario, your power bank could become useless. Given that it is an investment, it’s essential to look for a power bank that provides sufficient connectivity options.

Power banks are available with a range of USB ports, varying from one to four or even more. If you often need to charge multiple devices simultaneously, consider the number of USB ports the power bank offers. Additionally, you might explore wireless charging power banks, which can provide added convenience for your charging needs.

4. Input and Output Power

Input power refers to the power that a power bank accepts when you are charging it. In today’s fast-paced world, time is of great essence, and everyone desires to charge their power banks as quickly as possible. A power bank with higher input power can charge rapidly, ensuring it is ready for use when needed, especially crucial for power banks with higher battery capacities.

If you are willing to invest a bit more in a power bank, you might come across manufacturers offering the quick charging option, allowing you to recharge the power bank in the shortest possible time. When using a quick charging power bank, it is essential to use a USB cable that supports quick charging technology as well.

On the other hand, output power refers to the rate at which the power bank charges a device. Output amperage values are usually either 1 or 2 Amperes. However, some power banks offer higher output power to charge your phone faster. Different devices like Android devices, iPhones, and iPads may require varying output power levels. Nevertheless, this is not a concern unless your device experiences excessive heating or charges very slowly. If your power bank features quick charge technology, ensure to use the port that provides the quick charge option for optimal performance.

5. LED Indications

LED lights help you identify the status of the power bank whether it is being charged or being used to charge another device. It is easier to find out the charging status as the indicator lights show you how much charge is left in it. Without the LED indicators you may find it difficult to know when the power bank is nearing low battery. Most power banks, albeit a few, have charging status indicators.

6. Usage Patterns

How often have you thought of your usage pattern before buying a power bank? There are a variety of them in the market, but all of them may not meet your requirements.

If you are a heavy user or if you travel too often and are away from charging outlets for long hours, then you may need a power bank that provides more battery capacity even if it is bulky and heavy. But if you are an average user who finds his phone’s battery at about 10% by the end of the day and all you need is a charger that can help you extend the battery just for the time till you reach home then a power bank of lower capacity will be preferable.

7. Quality and Safety Options

Quality and safety should always be a top priority. Whether it pertains to your personal safety, the safety of your smartphone, or the well-being of the power bank itself, it all holds significant importance as it grants you peace of mind when using the product. It is advisable to steer clear of power banks that lack clear safety details or come from unknown brands.

Investing in a good-quality product from a reputable brand ensures that higher safety measures have been taken by the manufacturer. While a higher price tag might lead you to believe that the product is of superior quality, some well-established brands also offer affordable options that maintain high standards of safety and performance. Prioritizing quality and safety is crucial to ensure a positive and secure charging experience.

8. Price

Obviously, we need to make sure that we get all the best features at the most competitive and economical price. For this you need to devote some more time in comparing various models that you have shortlisted. Sometimes you may find that the same power bank proves to be more economical and sensible when bought from another site or store.

9. Reviews

Whenever you are buying any piece of technology, it is always important to ensure that the product has been tried and tested before. This can be done easily with the help of reviews. Always ask people for their opinion on the power bank after they have used it for some time. Initial opinions might be misleading; thus, it is best to ask only those people who have used the product for significant amount of time.

Will Charging With Portable Battery Bank Damage a Phone’s Battery?

Although it’s highly unlikely for your mobile portable charger to damage your phone battery, you can still take some safety measures just in case:

You Are Using A Bad Quality Power Bank

Quality is very important when choosing a power bank. A bad quality power bank can damage your phone’s battery, as well as your phone’s charging port. It can also create some security risks. For example, overcharging a bad quality Lithium-ion power bank can cause the power bank to explode.

Your Power Bank Has The Wrong Voltage

Having the wrong voltage in your power bank will lead to problems. The ideal voltage to charge a phone is 5V. If any battery pack charger gives a voltage of 4.2V or less, it will drain your battery instead of charging it.

Any voltage output greater than 5V will extensively damage your phone’s circuits by overloading it more than it can handle.

You Are Overcharging

Power banks should essentially be used sparingly. Using power banks to constantly keep your phone at 100% charge will over time damage the battery, which will lead to your phone not being able to retain its charge for long.

To avoid these problems, avoid using your power bank to overcharge your phone. Use it for emergencies, and even when you do use it avoid charging your phone up to 100%.

Advantages of wireless charging power bank

No Wires

Look ma, no wires! This is THE ultimate advantage of a wireless charging power bank for people who have the habit of misplacing their charging wires all the time.

With the wireless charging feature, all you need is a fully juiced-up power bank, and you are ready to charge.

Compatibility Across More Devices

Ever found a power bank and wire only to realize that the port is incompatible with the device you want to charge?

Say goodbye to the frustration of figuring out whether you need a USB-C or USB-A port and more with the widely compatible Qi wireless charging technology.

With more than 500 smartphone companies (yes, including the big leagues like Apple and Samsung) adopting this technology across their latest devices, it means that you can charge ANY Qi-enabled devices with the same wireless charging power bank.

Less Wear and Tear to Your Device Ports

No wires also mean less wear and tear to your ports.

Every time you insert and remove your charging cables exposes your device to potential damage – from frictional wear and tear, the introduction of dirt, and even potential corrosion when exposed to wet or damaged cables.

Want your ports to last longer? Switching over to wireless charging is a no-brainer.

Disadvantages of Wireless Charging Power Banks

Device Has to Stay on Charging Pad to Charge

Due to the wireless charging technology behind, the device must stay on the charging pad to be continuously charged.

If you are someone who enjoys using your phone while charging, then this may not be suitable for you. With a wired power bank, you can at least use it while it’s tethered to the power bank, but not with a wireless one.

It Has to Be Perfectly in Position to Charge

Unlike a wired power bank where you know that your device is charging as long as the cable is connected and turned on, devices need to be perfectly positioned in a specific orientation to be charged.

This is because there needs to be a precisely aligned orientation between the transmitter and the receiver of the magnetic field to generate the electrical current.

The good news? Many new companies are coming up with solutions for this challenge – from snap-on technology to helping you get in the right position all the time and more.

Takes a Little Longer Than Wired Charging

Compared to wired charging which is 100% efficient, wireless charging is up to 80% efficient, meaning some of the power is lost while transmitting electromagnetically.

This results in a slower charging process thus far. However, with improvements to the technology over time, this gap is expected to reduce significantly.

What is the difference between a portable charger and a power bank?

Both terms refer to the same type of product when it comes to pocket-sized battery packs designed to charge small electronic devices like cell phones. A portable charger is a type of power bank and can be designed to charge various devices, including portable battery chargers for cars.

In essence, there is no distinction between the two; power bank and portable charger are one and the same. The only variation lies in the size and capacity, with power banks generally having larger and more robust specifications for heavy usage with higher voltage and power capabilities. A power bank is essentially a set of batteries used for storing electricity, which can be used at a later time.

These lightweight power banks or mobile battery packs are convenient to carry anywhere you go. They are referred to by different names such as battery packs, power banks, portable chargers, pocket power cells, and back-up charging devices, among others. However, regardless of the name, their primary function remains the same – providing backup battery power to keep you connected at all times. Battery packs come in various shapes and sizes, with smaller ones fitting in your pocket for a quick smartphone boost, and larger ones capable of multiple charges or charging a tablet.

What should I look for when buying a power bank?

When selecting the best power bank to suit your needs, the initial consideration should be the battery capacity. Assess the duration of your travels and the number of devices you intend to use. Additionally, consider the energy consumption of these devices, as items like laptops or cameras will require more power for recharging compared to phones or tablets.

After determining the required battery capacity, the next factor to consider is the weight of the power bank. Typically, weight increases in proportion to capacity, so it may be prudent to strike a balance and prioritize portability by opting for a lighter power bank, even if it means sacrificing some battery capacity.

Compatibility is another crucial aspect to keep in mind. Ensure that the power bank is compatible with the devices you intend to charge. Also, consider the connectivity options. If you expect to charge multiple devices simultaneously, check the number of charging points the power bank offers.

Many power banks come with two or three ports, while some models boast up to six. Additionally, it’s worth examining the types of ports available. While USB-A ports suffice for charging, they may not charge devices as quickly. On the other hand, a power bank with a USB-C PD (Power Delivery) port will provide rapid charging for your devices. Taking these factors into account will help you find the ideal power bank for your charging needs.

What speed do I need?

If I had the authority, I would advocate for the prohibition of 5W power banks, as they are incredibly slow in charging. Anything lower than 10W would be off the table.

In today’s era, even 10W power banks, marketed as ‘fast charging,’ fall short of fully leveraging the capabilities of recent smartphones. With some devices supporting up to 120W over a wired connection, a 10W power bank might not deliver the level of convenience users desire.

While 10W power banks are more common among budget and mid-range options, many people use 10W chargers at home. However, I would strongly recommend seeking a faster power bank, particularly those with Quick Charge or Power Delivery support. Even if your current phone does not support these technologies, a future upgrade is likely to do so.

It may appear straightforward, but power bank manufacturers rarely provide the speed of their outputs in watts. Instead, you’ll often encounter ratings in amps, which you multiply by five (the voltage rating) to obtain the rating in watts. For instance, 2A x 5V = 10W.

Which outputs do I need?

For iPhone users (and those planning to stick with iPhones), a power bank with a Lightning port that serves as both input and output is ideal. This will save you the hassle of searching for cables that you wouldn’t otherwise use.

With Android phones increasingly adopting USB-C, a power bank with a USB-C port that acts as input and output is preferred. However, it’s still common to find power banks that can be recharged via Micro-USB, and sometimes you’ll come across power banks with both Micro-USB and USB-C ports. Avoid using them simultaneously for recharging the power bank, and keep in mind that USB-C generally offers faster charging.

The number of ports you need depends on how many devices you wish to charge simultaneously. If you intend to charge multiple devices, ensure that the power bank’s maximum output is higher than the sum of all ports combined. Some power banks may not be able to deliver the maximum rated output of all ports simultaneously. Additionally, consider the capacity of the power bank; it should be sufficient to fully charge all your devices.

Regarding plugging devices into ports with a higher power delivery capacity than they require, there’s no need to worry. USB devices will only draw the power they need. Many power banks feature intelligent technology that allocates power more efficiently among ports based on the devices being charged, often known as Power IQ or similar technology.

Wireless power banks are becoming more common. If you plan to use the power bank solely for wireless charging, you won’t need any outputs. However, you will still require an input to recharge the power bank itself.

How to choose the best portable charger for you

Determining the appropriate charger capacity: Look for a four to five-digit number followed by “mAh,” as it indicates the charger’s capacity. If you frequently need to recharge your phone and other gadgets, opt for at least 10,000mAh. For each additional device you charge, add at least 5,000 to the mAh rating you’re seeking. If your main concern is to prevent your device from reaching 0% during late nights out, a charger with a rating under 5,000 mAh should suffice, as long as you remember to recharge it regularly.

Be knowledgeable about ports: If you tend to keep your devices for a long time and are not familiar with USB-C ports, a charger that fits your budget may suffice. However, if you prefer faster charging, look for a power bank labeled with “PD” in its name. The best portable chargers, in my opinion, offer the fastest charging speeds and utilize the Power Delivery (PD) standard. Additionally, their USB-C ports enable you to recharge these power banks using the same cords used to charge modern laptops.

How we test portable chargers

To ensure that you get a charger that excels in refueling, we conducted rigorous testing. Armed with timers, we repeatedly drained an iPhone 12 and then measured the time it took for each power bank to recharge the phone. Throughout the process, we monitored how much of the iPhone 12’s battery was refilled after 15 and 60 minutes. To maintain consistency, we kept the iPhone at 100% brightness throughout the tests.

Our ranking also considered the portability and designs of each model, as smaller and pocket-friendly chargers have limitations in terms of the amount of battery power they can physically store compared to larger counterparts. Likewise, smaller chargers are less likely to have more than two ports—one for recharging the charger itself and the other for providing power to your devices.

How many mAh is a good power bank?

Anything from the 5000-2000 mAh in a power bank will work best for you, but you must remember you will more than likely not have multiple options for power included with a smaller device.

Which power bank is not allowed in flight?

Lithium batteries have a tendency to combust, and are therefore prohibited for cargo transport, as part of air-transport regulations.

How many watt hours is 20000mah?

72wh

20000 mAh at 3.6v is 72wh this is under the carryon limit.
