I have this funny feeling that Tronsmart, RAVPower, Aukey and Anker are using the same factory for these - very similar specs and features for all of these chargers. If I had the cash to get 5x ~$50 devices tested by someone like Clive, I'd definitely do it. I do worry about the internals of the device being swapped out silently by the manufacturers, though.
