I have 2 RAVPower batteries, both 20k. One had a 120v outlet on it, and I love them both. They don't overheat, have yet to lose capacity, and charge fast. They were the only ones I was happy with after using Anker, Duracell, Best Buy branded, etc. All would charge/output slow, heat up, lose capacity, etc. My next purchase from them is going to be their Solar Cell and their portable charging station. Def gonna try that charger out, had been eyeing it for a bit now, thanks for the heads-up!
