Overview
Not a mains charger, this lithium polymer jump starter stores power internally and releases it through an intelligent spark-proof cable to start gas and diesel engines.
A large battery, a protected cable and a storage case make it a complete emergency item. The limitation is vagueness in the engine rating and a pack that is bigger than a pocket unit.
Who it's for
Owners of cars, trucks, RVs and powersports vehicles who want headroom in starting current can carry it in a trunk or storage bay. Anyone with specialized heavy equipment should confirm ratings with the maker.
Pros and cons
- High stated starting current
- Spark-proof intelligent cable
- Storage case included
- Wide vehicle compatibility list
- Diesel size entry is unclear
- Pack is sizable
- Needs periodic recharging
Performance notes
A jump starter releases stored current through the cable for a few seconds, so battery charge and engine size set the limit. The intelligent cable is meant to block current when the clamps are connected wrongly. A depleted pack cannot start an engine, so periodic recharging over the Type-C cable matters.
