Overview
A glovebox or trunk holds this lithium jump starter, ready to start a dead battery on cars, SUVs and trucks and to charge devices from its power bank.
A large battery, a display and a full accessory set make it a complete emergency kit. The limitation is the engine size ceiling and the bulk of a pack this size.
Who it's for
Owners of cars, SUVs and light trucks within the rated engine sizes can carry it for roadside emergencies and device charging. Heavy-duty or commercial engines need a larger booster.
Pros and cons
- High stated starting current
- LED display and flashlight
- Power bank function
- Clamps, wall charger and adapter included
- Engine size ceiling for gas and diesel
- Pack is sizable for a glovebox
- Needs periodic recharging
Performance notes
A jump starter releases stored current through the clamps for a few seconds, so the main limits are battery charge and engine size. The display shows status so charge level can be checked before it is needed. A depleted pack cannot start a car, so periodic recharging from the wall charger or lighter adapter matters.
