3.5kW Portable DC EV Charger: Bringing Flexible DC Charging Wherever You Need It

When fixed EV charging stations are not available, a portable DC charger provides a practical backup charging solution. ELECTWAY’s 3.5kW Portable DC EV Charger is designed to bring DC charging capability directly to the vehicle, making it suitable for emergency charging, long-distance travel, outdoor trips, and backup use.

What Is a 3.5kW Portable DC EV Charger?

A 3.5kW Portable DC EV Charger is a compact mobile charging device that delivers DC power directly to an electric vehicle’s battery.

Unlike AC EV chargers, which rely on the vehicle’s built-in onboard charger (OBC) to convert AC power into DC power, a DC charger performs the power conversion within the charging equipment and supplies DC power directly to the vehicle battery.

For EV drivers who need an additional charging option beyond fixed charging stations, a portable DC charger can provide greater flexibility for travel and emergency situations.

Why Choose a Portable DC Charger?

Fixed charging infrastructure is not always available when an EV needs to be charged. This can be particularly important during long-distance travel, outdoor activities, or unexpected situations where access to a conventional charging station is limited.

The ELECTWAY 3.5kW Portable DC Charger is designed as a mobile backup charging solution. Its compact 330 × 164 × 105 mm enclosure and approximately 8 kg weight make it easy to store in a vehicle trunk and carry when needed.

The charger is designed for:

• EV backup charging
• Long-distance road trips
• Outdoor travel
• Emergency charging
• Mobile EV charging applications

3.5kW Portable DC Charger with Multiple Charging Standards

Different electric vehicles use different DC charging standards. To support a wide range of EV applications, the ELECTWAY portable charger is available in multiple connector versions:

• CCS1
• CCS2
• CHAdeMO
• GB/T
• NACS

This multi-standard approach allows the 3.5kW portable DC charger to be configured for different EV brands, vehicle markets, and charging requirements.

Compact 8kg Design for Mobile EV Charging

Portability is one of the key characteristics of this charger.

The unit measures 330 × 164 × 105 mm and weighs approximately 8 kg, allowing it to be stored conveniently in a vehicle trunk.

For drivers who want to keep a backup charging solution in their vehicle, the compact design makes the charger practical for mobile use without requiring a permanent installation.

3.5kW DC Output and Up to 95% Efficiency

The charger provides a rated DC output power of 3.5kW and achieves efficiency of up to 95%.

It uses a 220V single-phase AC input, making it suitable for applications where compatible single-phase power is available.

The charger also features a power factor of ≥0.99, helping optimize the use of available electrical power.

Built for Outdoor and Emergency Applications

Portable charging equipment may be used in a wide range of environmental conditions.

The ELECTWAY 3.5kW Portable DC Charger features IP65 protection and is designed to operate from -40°C to +50°C.

These characteristics make it suitable for outdoor travel, backup charging, and emergency charging scenarios where environmental conditions may vary.

Multiple Protection Functions for Safer Charging

The 3.5kW portable DC charger incorporates multiple protection functions to support safe operation, including:

• Overvoltage protection
• Overcurrent protection
• Short-circuit protection
• Leakage protection
• Overtemperature protection

The charger also supports dynamic load balancing, which can adjust charging power according to the available electrical load.

This feature can help the charger adapt to changing power availability during mobile charging.

Who Can Benefit from a 3.5kW Portable DC Charger?

A portable DC EV charger can be useful for EV owners and businesses that need flexible charging beyond fixed charging infrastructure.

Typical applications include:
