This one is an EDC for me for when I'm moving a lot on a long day or overnight when I expect to have access to mains sockets through the day.

Why I like it
- it occupies only 1 power socket, non-blocking others, so works in really confined spaces
- it is very light so it doesn't fall out so often in worn power sockets like hotels, airports, airline in-seat.
- two sockets so whilst its only 12W it does usually a mobile and say a BT headset. I defensively recharge, if I'm near a power socket I use it regardless of battery levels because "why not" so I'm prep'd for whatever is happening next.
- folding pins

Anker just don't anything like it. Everything Anker is basically huge in comparison with more Wattage.
So I just ordered the Powercore Fusion 5000 and guess what, it will replace likely the Powercore Slim 5000 and still sit with the Aukey so then I got 2 chargers, and if the mains sockets is constrained (narrow, or loose) the Aukey will be charging Anker.
I'm not sure I want Anker to make an equivalent, if they did it would need to be (somehow) better.
