Best External Batteries (2022)

Best External Batteries : Our smartphones are used for everything, and even sometimes, to call. The problem is that the more efficient they are, the less battery they have. We all dream of a smartphone that would have the longevity of our good old 3310 .

To learn how to choose your charging battery, refer directly to our buying guide.

Charmast 10,000 mAh – The best With LCD Screen

• The Plus
  • Price
  • Compact design
  • Quick Charge/PD Adapter
• The Least
  • Its weight
  • Port USB-C
• Not currently available in the US

The Charmast external battery has a very convenient LCD screen, which gives you the status of your battery and therefore the remaining autonomy.

It also has three outputs, which will come in handy if you have multiple devices to charge. There are two full-size USB ports, plus a USB-C PD port that can serve as both input and output, and all three support 18W fast charging, but only one at a time.

On the side is an additional Micro-USB port compatible with Quick Charge 2.0, which can also be used to charge the bank. It charges in about 3.5 hours with a Quick Charge/PD adapter, but in about 5.5 hours with a standard 10W charger.

The downside of this design is that it’s a bit larger than most super thin models of similar capacity on the market. This Charmast is about the same width as a phone, but it’s a bit shorter and a bit more massive. It weighs 228 grams, which is perhaps more suitable for a bag than for your pocket.

Charmast provides a soft mesh carrying case and a short USB-A to USB-C cable in the box, a nice touch.

Charmast 10,400mAh Power Bank – Best External Battery with Screen

• The Plus
  • A safe bet
  • LCD
  • More inputs and outputs
• The Least
  • Larger than many 10K models
• $22.99

This Charmast battery is the only model with an LCD screen in our comparison.

Its display is very convenient to know exactly how much autonomy there is left. It also has three outputs, which will come in handy if you have multiple devices to charge. There are two full-size USB ports, plus a USB-C PD port that can serve as both input and output, and all three support 18W fast charging.

On the side is an additional Micro-USB port compatible with Quick Charge 2.0. It can also be used to charge your external battery in about 3.5 hours with a Quick Charge/PD adapter, and in about 5.5 hours with a standard 10W charger.

Charmast provides you with a soft mesh carrying case and a short USB-A to USB-C cable.

JIGA 30,000mAh – The Most Versatile

• The Plus
  • Nice capacity
  • Compatible with Android and iOS
• The Least
  • Plastic design
  • No USB-C output
• $32.95

Despite its somewhat old-fashioned, plastic design and a built-in LED flash (certainly useful for camping trips), this JIGA also takes us back to the days when there was no need to sacrifice ports to achieve some portability.

It is even surprisingly small for such a large capacity battery, even if it remains more suitable for bags than pockets.

The JIGA has USB-C, Micro-USB and Lightning inputs, allowing you to charge it with any cable. It’s a shame that the USB-C port doesn’t work like an output, but each has a rated power of 10.5W.

It’s not about the Power Delivery speeds we’re getting used to, but it’s fast enough to charge a phone (or multiple phones).

If all you need is a healthy flow of energy to increase the battery life of your devices, then this external battery will be very convenient to have on hand.

Anker PowerCore Essential – The Best Value For Money

• The Plus
  • PowerIQ Technology
  • Power Delivery Technology
  • Power of 20,000 mAh
• The Least
  • Incompatible with USB-C laptops
• $59.99

The PowerCore Essential is a black plastic battery and relatively compact. It has a textured upper surface that improves its grip.

Its USB output uses Anker’s PowerIQ intelligent charging algorithm. It is also connected to a USB-C port that plays both the role of input and output. On the top, you’ll find a power button with four built-in LEDs that reveal its remaining capacity.

The latter is 20,000 mAh and it offers several charges, including for the iPhone XS, Samsung Galaxy S10 and iPad mini. With support for Power Delivery technologies and fast charging, you can power almost any mobile device.

A USB-C to USB-C cable and a soft mesh carrying case are provided in the box.

Anker PowerCore III 10K Wireless – The Best Wireless External Battery

• The Plus
  • Total power of 18W
  • Built-in phone holder
• The Least
  • Incompatible MagSafe, Apple Watch or Samsung Watch
• $39.99

As the name suggests, the PowerCore III 10K has a decent-sized 10,000mAh battery, which should allow you to charge your smartphone at least three times before losing its battery life.

The wireless charger has a rated power of 10W. To work properly, simply place your device in the center of the circle. Nevertheless, it does not start automatically, you must first press its Power button.

You can also charge your devices from its two USB-A ports located on one of its ends, for a total power of 18 W.

How To Choose The Right Portable Battery?

Choosing the right portable battery depends on your needs and devices. It’s all about finding the balance between portability, cost, number of recharges and speed of recharging.

Some will prefer a portable battery that fits easily into a bag and offers two full recharges of their mobile phone, others will choose a larger battery that has it under the hood, and that allows you to charge several devices at the same time.
