Power Banks & External Batteries

In this section of our online shop, you will find a selection of the best power banks in 2026.

All smartphones on the market and a large number of electronic devices can be charged (or powered) via a USB port, regardless of its type (USB, USB-C, micro USB...). This universal charging method has proven its worth since its creation, particularly in terms of reliability and convenience. However, the more recent mobile devices are — whether phones, tablets, handheld consoles or Go Pro cameras for example — the more powerful and energy hungry they are, which strongly affects their battery life. This is where, once you've moved away from a wall outlet, the usefulness of an external battery, also known as a power bank, really makes sense. These mobile batteries, from the most compact to the most powerful, let you recharge one or more devices on the go, which is perfect for many everyday uses, or while travelling. Power banks come in many variants, in terms of dimensions, features or power.
Let us present our selection of external batteries, among the widest possible choice, across these different variants.

Anker PowerCore Lite 10000

$24.99 (46)

Discover the Anker PowerCore Lite 10000, one of the thinnest and lightest power banks on the market for its capacity.

  • Capacity: 10000 mAh / 37Wh
  • Dimensions: 140 x 70 x 15 mm
  • Weight: 211g
  • Output: 1 USB port 5V⎓2.4A
  • Ultra-slim, 2 different input ports (micro-USB + USB-C)
In order to make it easier to carry, even in a pocket, Anker has decided to offer an external battery in a different, flatter, and more practical format. With a format similar to a Samsung Galaxy S8 (lower), the PowerCore Lite has two different input ports, allowing it to be charged either with a micro-USB cable or a USB-C cable (not both at the same time), which is particularly convenient.
One of our team's favorites: robust, well designed and very practical day to day thanks to its dual input port — the only downside being the lack of fast charging.

VIII - Related questions

How do you choose an external battery? First, take stock of your needs. Does the power bank need to be compact enough to fit in your pocket, or does capacity matter more than size? How many times do you want to recharge your smartphone (check its capacity in mAh)? Do you need fast charging? Finally, factor in your budget, and with our help you'll know which external battery to choose.

All external batteries recharge via a simple USB port. Whether it uses a micro-USB cable or a USB-C cable (rarer), any power bank can be recharged on the same wall charger as your smartphone, or on any device with a USB port, such as your computer. This simplicity explains the great success of this type of battery.

External batteries are most often made up of one or more cells (often 18650-type cells) wired in parallel, with a sophisticated electronic circuit (managing charge and discharge, with integrated protection circuits), all enclosed in a protective shell. Their characteristics generally depend on the number of cells and the electronic circuit.
