A portable, single-output North American 12 V AC charger for listed lead-acid and LiFePO₄ batteries, with separate Supply and float-maintenance use. Its exact manual and U.S. sheet specify 22 A; the page also uses a 25 A headline, a discrepancy kept visible in the review.

Explore this buying guide ↗Why consider this model?
- A portable, single-output workshop charger when a 12 V lead-acid or LiFePO₄ battery needs a comparatively high 22 A charging rating and falls within the maker's chemistry-specific size range. Its separate 13.6 V Supply program is documented for float maintenance; broader diagnostic power use conflicts with a manual safety warning.
Tradeoffs to weigh
- The exact page's 25 A headline conflicts with its detailed 22 A table and the matching North American manual and U.S. sheet; this assessment uses 22 A. It is 12 V and one output only, its capacity filter cannot test the published 450/500 Ah ceilings or enforce the stated 30/40 Ah lower edges, and the manual does not establish a lithium BMS condition. Supply mode disables spark protection, and the manual prohibits rain, snow and frozen-battery charging.
