Editorial notes

Why it stands out

Why we like it

Car and Driver named it its 2026 Best Overall. The long leads and large clamps make it easier to connect than compact packs, especially when the battery is not close to the pack.

Clore states the unit is certified by SGS laboratories to the UL 2743 standard. It is the only maker in this group that names a third-party safety certification. Replacement charging kits and cable and clamp sets are available.

What to know

Skip it if you want phone and laptop charging or a stated battery capacity. It needed the override to start a fully dead battery in Car and Driver's test, and Clore publishes no capacity.
