The batteries in all these power banks are 3.7V, but USB charging occurs at 5V. This means that every 10000 mAh battery pack has a usable maximum of 7400 mAh (10000 / 5 * 3.7). Then charging inherently incurs efficiency losses – about 20% on average – meaning you can expect the final (or "rated") capacity of pretty much all 10000 mAh battery packs to be around 5920 mAh (7400 * 80%) – though some are more or less efficient than others.

Not entirely sure that pertains to what you were seeing, but hopefully it helps!
I only got 26.55 Wh out of this in my initial test ([email protected] discharge, which, uh, is also less than the rated 20W; it can however do [email protected]).

It's labeled for ≥ 75% efficiency and ≥ 37 Wh, so it's either < 72% efficiency or < 37 Wh, either of which violates the text on the unit itself. I'm charging it back up now to see if we can wheedle out which it is, but this isn't a great first impression and I'm probably returning it.

edit: charging it back up at 5V@2A cost 39.3 Wh. I got 31.6 Wh discharging at [email protected]. So it seems like the efficiency is just bad.

Good find! This is actually $2 cheaper than their previous sale in July. Too bad only the black one is priced at this rate and not the white one. I've just ordered myself another one~

these are fine and dandy until your phone overheats and you've got a small fire!

I would not compare this brand with other no names. Better buy Baseus, it's a better chinese company with a great customer service

Have this, seems decent since it should be able to charge 2 at once. I do wish it had a numerical battery charge display like my older off brand battery had. Its a bit slippery like carbon fiber but seems good so far. Was looking for Anker or another "name brand" one but those were more $ or had older tech (no usb output)

Ignore all the complaints from people who have never even used the device. This does everything it's marketed to do. USB-C in and out. PD quick charging at 18w.
