Will it start a diesel truck?

The 4000A peak rating is aimed at gas engines up to about 10.0L. It can boost many diesel engines too, but very large diesels may need a higher-capacity unit.

How do I recharge the GP4000?

Through its USB-C input, using a USB-C charger or car adapter. A full recharge takes several hours, so plan ahead before a trip.

Can I leave it in the car?

Yes, lithium jump starters are commonly stored in the trunk. Keep it out of direct sun and recharge it every few months so it is ready when needed.

What comes in the box?

The jump starter, smart jumper cables with metal clamps, and a USB-C charging cable. A wall charger is not always included, so check the kit before buying.

Is $79.99 a good price?

That is the best new price across the two stores listing it as of November 7, 2026. For a 4000A-class unit with USB-C, it sits at the low end of what this capacity usually costs.

Pros

4000A peak rating covers large gas engines up to about 10.0L
88.8Wh battery doubles as a power bank with two USB ports
USB-C input and output for charging the unit and other devices
All-metal clamps hold up better than plastic-bodied ones

Cons

Peak amps are a momentary figure; real cranking power is lower

No wall charger included with every kit, so USB-C charging is slow
Cable and clamp length can be tight on batteries in deep engine bays
