Product Description

Mobile AC EV Charger 3500W Trolley Case for Parking Lots and Fleet Roadside Assistance

Deploying fixed charging infrastructure means cable runs, trenching and site approval. This mobile AC EV charger skips all of it: a 3.5kWh or 5kWh LiFePO4 pack, 3500W rated / 7000W peak inverter and 92% conversion efficiency at 220V sit inside a 466 x 230 x 550mm trolley case on wheels. One operator rolls it to the bay that needs power, starts charging, and moves it again when demand shifts. With no wiring, no civil works and no site modification, the capital outlay per charging point drops sharply - which is why fleet operators, parking lot owners and highway service area managers use it as a fast, low-cost capacity buffer.

Key Features

Zero wiring deployment: Eliminates cable laying, trenching and site modification, cutting installation cost and lead time to hours.
Mobile by design: 466 x 230 x 550mm trolley case at 39kg net weight rolls between bays, service areas and roadside locations.
3500W rated, 7000W peak: Covers EV charging plus digital devices and small appliances from a single unit, with automatic cut-off above 3700W.
92% efficiency at 220V: Higher conversion efficiency lowers energy loss per charging session and extends usable runtime.
Off-grid capability: Runs independently of the grid and accepts solar and other green energy input for remote sites.
Capacity choice: Select 3.5kWh or 5kWh at order time to match expected daily session volume; both share the same enclosure and 55kg packed weight.

FAQ

Q: Why choose mobile instead of a fixed charging post?

A: A fixed post needs cable runs, civil works and site approval. This unit needs none of them, so a charging point can be operational within minutes at a fraction of the investment.

Q: Which capacity should we order?

A: 3.5kWh suits occasional top-up duty; 5kWh suits higher session volume. Both use the same 51.2V 15AH LiFePO4 platform and 3500W inverter, and the packed weight stays around 55kg.

Q: What can be powered from the unit?

A: EVs through a portable AC charging cable, plus digital devices and small appliances, at 229V no-load / 216V full-load output.
