Product Description

Portable AC EV Charger 3500W 3.5kWh LiFePO4 Trolley Case Emergency Power Station

This portable mobile energy storage power supply packages a 3.5kWh LiFePO4 battery and a 3500W inverter into a trolley case housing. It delivers 229V no-load and 216V full-load AC output, peaks at 7000W for motor start-up loads, and protects itself automatically once the load exceeds 3700W. Weighing 39kg with a retractable handle and wheels, one person can roll it into any service bay, parking space or roadside location and start charging within minutes - no wiring, no site modification.

Key Features

3500W rated, 7000W peak: Handles EV onboard chargers, power tools and appliances with enough headroom for inductive start-up spikes.
51.2V LiFePO4 battery: 48-57.6V working window, 15AH cells, long cycle life and stable output under high ambient temperatures.
Built-in automatic protection: Output is cut off above 3700W, protecting the inverter and the connected vehicle.
92% inverter efficiency: Up to 92% conversion efficiency at 220V keeps more stored energy available for the vehicle.
15A constant current charging: 186-236V / 50-60Hz AC input recharges the pack from a standard wall socket.
Trolley case mobility: 466 x 230 x 550mm body with wheels; deploy on demand instead of installing a fixed post.

FAQ

Q: Can it charge an EV directly?

A: Yes. It outputs 220V class AC power, so EVs with a portable AC charging cable, plus digital devices and small appliances, can be powered wherever the unit is rolled.

Q: What happens if the load is too high?

A: The unit automatically protects itself when output exceeds 3700W, which is above the 3500W rated power.

Q: How is the unit recharged?

A: From any 186-236V, 50/60Hz socket using a 15A constant current charge profile. Solar and other green energy sources can be combined through the off-grid DC input.
