Does exactly what you expect from a power bank.

Wonderfully simple and reliable.

  • Powerful enough
  • Fast loading time
  • Tough enough for your mild adventures

Bought two units on top of my current 40k mah unit to be able to do long motorcycle treks. A power bank is standard in my inner pocket, one on the charging cable and one as a backup. From walks in nature to motorcycle rides in cold (0°C) to warm (30°C) never really had any complaints about the performance of this product. Very reliable and easy to use.
If there could be any complaints, it is that you have to estimate how much the power bank is still charged based on the LED indicator, but never really had any problems with it due to its large volume.

good

great power bank does what it should do
downside: according to the manual, the power bank with a 20w charger would be full again in 2.5 hours
can of course not with a capacity of 20000mah, so takes about 7.5 hours

Satisfied, after buying the right USB cable excellent!

We had followed CoolBlue's choice for the corresponding plug. Unfortunately we had to buy an extra USB C-USB C cable because the supplied cable was USB C-USB A.
