A portable 120 V AC 12 V charger with 15/8/2 A and automatic charge-rate selections, separate STD/AGM/LiFePO4 modes, an LCD, winter mode and a vehicle-memory power-supply mode rated up to 10 A. Its exact manual identifies P/N 022-0234 and says not to expose the unit to rain or snow. Conflicting 14–250 and 50–300 Ah page claims leave its supported maximum capacity unresolved.

Explore this buying guide ↗Why consider this model?
- A portable 12 V shop charger for a battery whose manufacturer approves one of its selectable charge rates, especially when the LCD, winter mode or a dedicated vehicle-memory backup mode is useful. The named battery-charge rates are 2, 8 and 15 A; the 15 A output is not a promise that a larger battery can be charged safely or within a fixed time.
Tradeoffs to weigh
- The exact product page gives incompatible battery-capacity ranges (14–250 Ah and 50–300 Ah), and its manual supplies no ceiling, so the questionnaire does not match it to a numeric battery-capacity request. The LiFePO4 BMS condition is unknown. The manual requires dry use; it also describes the separate power supply only for retaining vehicle settings while a battery is removed, and does not state its voltage. The advertised winter mode and automatic charge rate do not replace battery-maker guidance.
