Antigravity XP-20-HD Micro-Start Jump Starter

The XP-20-HD is the jump pack for the truck owner who does not want to wonder whether the little battery box has enough authority for a big engine. Antigravity rates the current HD unit at 930A starting current, 4,650A peak and 24,000 mAh capacity, with support for diesels up to 8L and gas engines up to 10L.

It also doubles as a high-capacity USB-C/12V power supply, but the reason we would carry it is simpler: no second vehicle required. Keep it charged, store the clamps with it, and a dead starting battery becomes a five-minute problem instead of the moment the whole trip stops.
