is a better question.
I go for brands I trust - e.g. Anker - and haven't burned down my house/car yet.
The risk is not the part that actually charges your phone; it's in the part that transforms mains (240VAC here in the UK, 110VAC in Trumpistan) into something that won't instantly explode your phone. We call this part the "transformer" :p, and quality varies wildly.
