Your phone takes 5v, like 1a
It would fuck it up

Newer / larger smart phones and tablets use 5v at 2.1A. Smaller phones and dumb phones usually use around 5v at 1A.

I'd get a battery pack that can accept higher charging voltage / amperage that has USB outputs.
Probably safer than DIY'n it if you don't have much experience. One could build a cheap circuit to step the charger output down to safe levels, but if done wrong that cheap circuit could brick a much more expensive phone / device.

There's literally all in one circuits for these on amazon for $4

or car 12-24v -> usb adapter, just tack it to that.

1c + postage, or chink crap in most stores. idk why, they couldnt just supply an adapter, but, Ive also heard people _claiming_, their phone got fuxored using solar usb chargers. But throwing 19v direct at 5v device def. aint good idea either, desu.
