With a 10,400 mAh battery, Charmast intends to offer you more autonomy on your portable devices, particularly smartphones. But with actual capacity falling short of what it claims, the 10400 mAh Power Bank doesn’t do as much as promised.

Despite a real capacity very different from that announced, the 10400 mAh Power Bank battery from Charmast should not be completely banned. It offers a good boost to your smartphones, and quite quickly thanks to its USB-C port capable of delivering 18 W of power. Too bad it’s not a speed champion when it comes to refueling .

Strong points

  • Quite sober.
  • 4 USB ports.
  • Average charging power.
  • Digital display of remaining capacity.

Weak points

  • Rather slow charging.
  • Micro-USB a little dated.

NB: The reported price drop is calculated by comparing the lowest price of the day with the average of the lowest prices charged by all merchants for the product last month, with security rules to exclude the prices of stores whose the VAT policy is not clear (so-called “gray” stores, typically in the case of imports from China).

Alternatively

The Iniu Power Bank 10500 mAh portable external battery has good charging power, but also Power Delivery technology and a compact enough format to take it anywhere without discomfort. So many arguments which allow the device to stand out in our comparison. Add the presence of a flashlight and a practical kickstand and you have a powerbank ready to charge your smartphones.
