Portable AC EV Charger 3.5kWh Trolley Wheels Off-Grid Solar LFP 3500W 92% Efficiency

This 3.5kWh portable AC EV charger is built as a trolley case with built-in wheels, so a single operator can move it between parking bays, service points and temporary sites without lifting equipment or site preparation. Inside the case sits a 51.2V LiFePO4 battery pack and a 3500W inverter, giving electric vehicle owners a complete power source that works with or without a grid connection.

The platform is available in 3.5kWh and 5kWh versions, so distributors and fleet buyers can match run time and budget to each deployment instead of over-specifying a single model. Both versions share the same enclosure, connectors and control interface, which keeps spare parts and staff training simple.

• Trolley case with wheels: compact 466 x 230 x 550 mm body, 39kg net weight, about 55kg packed for freight
• Off-grid operation: the internal LFP battery delivers power with no grid connection required
• Solar ready: an external PV panel can recharge the pack for green energy cycling at remote sites
• Strong inverter output: 3500W rated, 7000W peak, with automatic overload protection
• High conversion efficiency: up to 92% at 220V, which reduces energy loss and heat
• 15A constant current output: suitable for EV top-up charging and for running several devices at once
• Stable LFP battery: 51.2V rated, 48-57.6V working range, long cycle life and thermal stability
• Wide AC input range: 186-236V and 50/60Hz, compatible with mains supplies in many countries
• Smart output regulation: 229V no load and 216V at full load for consistent supply
• Low deployment cost: no cable trenching and no site modification, so units go live quickly
