Custom OEM Portable DC Fast Charger Factory & Suppliers

Your Trusted Partner in Global EV Infrastructure & Advanced Mobile Power Solutions

The Global Evolution of Portable DC Charging

The global transition to Electric Vehicles (EVs) has triggered an unprecedented surge in demand for flexible, high-speed charging infrastructure. While stationary DC charging stations are becoming more common, the Portable DC Fast Charger has emerged as a game-changing tool for fleet operators, automotive dealerships, roadside assistance providers, and residential users who require "power on the go."

Industry reports indicate that the portable charging market is set to grow at a CAGR of over 20% through 2030. This growth is driven by the need to bridge the gap in grid-limited areas and to provide localized fast-charging solutions without the heavy capital expenditure of fixed installations.

High Power Density

Modern portable DC chargers now offer power outputs from 20kW to 60kW in compact, luggage-sized formats, allowing for 80% charge in less than an hour.

🌐

Global Protocol Compatibility

Transitioning between CCS1, CCS2, CHAdeMO, and GB/T is seamless with our multi-standard adaptive technology, meeting diverse international requirements.

📱

Smart Connectivity

Integration with OCPP 1.6J/2.0.1 protocols ensures that portable units can be managed remotely as part of a larger charging network.
