A compact multi-function charger that jump-starts, charges quickly and maintains a battery between uses. It handles twelve volt batteries only, so it will not cover older six volt systems.

Overview
A yellow case holds three jobs: a high-current engine start, a fast charge and a low-current maintainer. A small LCD reports status, and an alternator test checks whether the charging system is working.
It earns its place by combining charging, starting and checking in a light housing that is easy to store. Electric pulse technology and an automatic reconditioner address sulfate build-up on aging plates. Drawbacks are a long wait for a full recharge and no support for older systems.
Who it's for
Owners of several cars, boats or small engine equipment who hold batteries on a regular charge. Fleet-style use with deeply drained batteries may call for a bigger unit.
Pros and cons
- Charges, starts and maintains
- LCD status screen
- Alternator check built in
- Light and compact housing
- No six volt support
- Full charge takes long
- Input voltage data is confusing
- Only one-year coverage
Performance notes
Charging speed follows the amp setting and the state of the battery being charged. The reconditioner checks whether a battery can accept charge, then runs a pulse mode to break down sulfate if needed. After charging it drops to a low-current maintain mode that can stay connected.
