The GOOLOO A9 Ultra is a massive 6000A portable jump starter that doubles as an onboard air compressor. In addition to that, it can be used a power station, providing 100 Watt-hours of energy. It’s a massively-capable jump starter that is really useful to keep in your vehicle should an on-the-road emergency occur.

Although most portable jump starters are very small compared to the past, they are still at least a couple inches thick. The GOOLOO GP Warrior is the thinnest portable jump starter I’ve come across, measuring at just over one inch thick. Aside from the sleeker profile, the jump starter works great and really fits the term, portable.
