Portable AC EV Charger 51.2V LiFePO4 Battery 3500W Inverter 92% Efficiency 39kg Compact Outdoor

Portable AC EV Charger - 51.2V LiFePO4 Energy Storage Power Station

Built-in LiFePO4 pack, 92% inverter efficiency and stable 216V full load output in a 39kg portable chassis.

Key Features

• Built-in 51.2V LiFePO4 energy storage pack operating between 48V and 57.6V, using 15AH prismatic cells with more than 3000 cycles and high thermal stability.
• LiFePO4 chemistry does not suffer the thermal runaway risk of ternary lithium packs, making the unit safer for indoor storage, vehicles and public events.
• Inverter efficiency up to 92%, delivering 229V at no load and 216V at full load, so output voltage stays within a narrow band instead of sagging under load.
• Stable 216V full load output keeps EV on-board chargers and motor loads running without derating or repeated restart.
• Compact body with 39kg net weight and about 55kg packed weight, movable by two people or with a trolley for outdoor backup and emergency charging duty.
• Integrated BMS with cell balancing, over charge, over discharge, over current and short circuit protection, plus a clear state of charge display.
• Expandable charging options: mains AC charging and solar input supported, so the pack can be replenished off-grid between jobs.
