Buy the one with 2 ports, type A.
Impressive, I was expecting something subpar, but both charge at almost 4000 ampere/hour. Tested with the "Ampere" program from the Google Store.
I have NOT tried both at the same time.
It maintains the charging speed very well and the phone itself detects it as turbo charging (Honor 400).
The charger is super small, which makes it a bit difficult to remove; it fits very snugly, which is good, but pulling the chrome ring to remove it is not the best option. It bends and you end up holding it on the controller, so you have to press hard on the edge to take it out.
I don't leave it on all the time because in my car, with the key removed, I see that it has a blue LED that's always on and I don't want it to drain the battery.
I'm going to order 2 more for some friends. We just have to wait and see how they perform over time and with use.
It's not very fast when charging (approximately 700mA), but it's versatile if you want to convert a cigarette lighter socket into USB A or C, and it fits very well when recessed.
