I have a couple of low-energy USB devices I'm travelling with that seem to work absolutely perfect with. It only came charged with most of the first dot, so I spent a significant part of the day getting it to part of the third dot using a standard USB plug before remembering I have a Chromebook charger that operates as a superfast charger that finally got it from somewhere in 2 dots to somewhere in 3 dots.

I haven't been able to dispense with the purpose of the external battery long enough in the two days I've had it to see how long it takes to get it to full charge but I also haven't killed it with the use. That said, getting the charge from somewhere in flashing third dot down to somewhere in flashing second dot with my two low-energy devices took about 15 hours.

I tried using it to charge my Note 2020 Ultra and it was very slow, even using the cord I use from the Chromebook fast charger, which when using the Chromebook base only takes 25 minutes to get from 15% to 100%. So, I threw it back on the regular charger so I could charge my phone and forgot about it for about 10 hours, and it remained on the second dot. For about an hour before I needed it to utilize the low-energy devices, it charged and got from wherever it was on the second dot to somewhere on the third dot. The devices have been going about 3 hours now and it is still on the 3rd dot.

It's really good for the project I'm working on with the low-energy devices I'm using. I don't know how long I could get away with using them both at max power but if it's at least a few days I won't have to update to talk about how or whether or if this was a mistake *for that purpose* since that was the purpose for which I bought it. However, if you have a high-usage phone that is fast-charge capable, this may not be the PowerBank for you. I wasn't using my phone (which is always on Power-Saving mode) while it was charging, but it only went up, maybe, 10% (I don't remember exactly but it wasn't very impressive) in almost 30 minutes.

I love Anker products and almost have never had problems with it. And the ONE time I did YEARS ago: they made it right as soon as I made it known with a very quick replacement. This one just isn't the giant one I did buy to charge my phone--which also does do a good job of charging my mom's iPad, Nord work phone, and S22 Ultra. The sale, small size, and promise of high-voltage USBs is what I bought this for knowing I needed it to operate at a low-level plug in a more portable way. So far, it's fulfilled that perfectly and for that purpose I have no complaints =)
