There's a type of charger that Aukey make which Anker didn't and so bought Aukey for $5.
There is a type of solar charger Choetech make which Anker doesn't. I have repeatedly asked Anker for a product change, they not done, so have a Choetech solar charger.
For everything else it is Anker because I get excellent warranty and the products fail inrequently.
I buy for about 11 people at the moment and it's nearly all Anker to the horizon. I will get a warranty issue every few months but it's a light effort to solve across the dozens of products.
My payback to Anker is trying to help in this community as good people should be supported.
Typed in an airport day 3 of 14 days moving, powered by Anker (apart from the Aukey charger which fits in the tiny sockets the Anker doesn't fit).
