Bought this in 2017 for $11.10, Still going strong after almost 3 years
I hate you SD, for continually tempting me to get yet another, even more powerful, power bank, that I don't really need, except perhaps for the zombie apocalypse.

LOL, same. I have enough SD battery banks that we could survive a few months.
Btw, a tech question. How much energy loss is there in charging a device from a power bank vs. from a power adapter?
I.e. how much of the power going into a decent wall adapter ends up my my phone's battery when the two are directly connecting using a decent USB cable, versus how much of the power going into the same wall adapter ends up my my phone's battery if the wall adapter is used to charge a decent power bank, which in turn charges my phone?
Mostly I'm just curious, but I'm also thinking of charging all my devices from power banks instead of from wall adapters (actually, in my case it's not a wall adapter but a solar panel with a USB output, and it's just a lot more convenient to charge power banks from it than devices).
Also, while we're at it, why so cheap for a 20Ah power bank?
And do any of these come with wireless charging, either to be charged or to charge other devices--or both?
