Dunno, kinda tempted, would buy at 2/$6 just to find out what they are like, but am leery of getting 4 of them. I’ve had crappy luck with small chargers in the past. I do like the combo of a charger and flashlight, but I wish measurements and weight were included.
My biggest headache is that my phone is very fussy about cables and they wear out fast, so the short USB Micro-B cords that come with these chargers are of value to me in their own right.
I’d hesitate to give these out at gifts without testing them through a complete charge cycle first, because of earlier poor experiences with 1 cell chargers. Also, new phones these days use USB-C meaning another adapter or cable would be needed with these older chargers.
