Best for most car campers
Jackery Explorer 300
The right size for the draw most people actually have. Light enough to carry one-handed.
This is the size that matches what car campers actually draw: a fan at night, a laptop in the evening, phones, a light. It is light enough to carry around a site one-handed, which matters more than it sounds, and it refills from the car while you drive rather than needing mains power. The honest limits are chemistry and capacity. Lithium-ion gives fewer cycles over a lifetime than LiFePO4, and a continuously running fridge needs several times this capacity.

Good for
- Covers a fan overnight plus laptop and phone charging, which is the common real need

- Lithium-ion rather than LiFePO4, so fewer charge cycles over its life
- Not enough for a 12V fridge running continuously
- The single AC outlet limits you if two devices need wall power
