    Colour doesn't affect its performance. Nobody is coming up to you ooohhing and aaahing at a pink powerbank.

    However based on comment further down, it's not even the advertised mAh

      My girl has a blue iPhone so she wanted a blue power bank. And her peers WILL oooh and aaah, at least for the first time.
      If for 17 dollarbucks y not.

  I tested this. 66% of rated capacity at 9V 20W.

  Based on the Wh needed for charging it, I suspect it does not have 10,000 mAh worth of cells.

  Based on the form factor, I think it might use something like 2x 3,500 mAh 21700 cells.

  It's likely an ok 7000 mAh power bank for $17.49. But I wouldn't pay more than $20 for it.

  All the Charmast power banks I've tested have been varying levels of under capacity and unable to output the wattages listed. So the brand is best avoided IMO.

    You ever tested the INIU? I recently bought one of those 😅🤔

      Yep. The INIU B6 gives 85% of the rated capacity, which is a good result. It's one of the best cheap 10,000 mAh power banks available IMO.
