Small, reasonable materials, rapid charging of smartphones

The workmanship is good, mostly metal, with push button to activate. On the side of the head, I have a few small scratches from the US plugs. However, this has no effect on the function.
The USB cable is ok, but not particularly high. A commercially available USB replacement cable there are in every household several times or you can buy just in case for pennies a new one.

The battery is charging a smartphone imho much faster than a cigarette lighter adapter or even the Radio / Car USB sockets. While charging the external battery itself takes a while but the 3000 capacity is practicable than the really big battery definitely.

I like the thing: the way no outlet search much more efficient in the car, no annoying fiddling with spare batteries (who does that with dual SIM smartphones ...).
