How to choose a portable charger

AG Electrical April.2022


First of all, we ought to clarify what exact the portable EV charger is.

According to the standard IEC 51857, we can find all the 4 methods of EV charging.

After reading the details of the definition we can easily find that the Mode 2 accurately describes the portable EV charger.


Mode 2 charging involves the use of a special cable with integrated shock protection against AC and DC currents. In Mode 2 charging, the charging cable is provided with the EV. Unlike Mode 1 charging, Mode 2 charging cables have built-in protection in the cables which protects against electric shock. Mode 2 charging is currently the most common mode of charging EVs.

Now we understand that the portable EV charger is consist of four major parts: output plug, cable, control box and input plug. You can refer to the following picture.


Make sure all these four parts fulfill your demands and real working environment, then your EV equips with a perfect portable charger.

1. The input plug type.


Find out the input plug type in your regular charging places, also the voltage/current of their power infrastructure.

2. control box.

Hereby we do not discuss the out shape, it is the personal choice.

Only two points I think is important or essential to talk about.

The screen to monitor the working status at real time: voltage, current, temperature, time and etc.....

The protection it offers which makes the charging safety and intelligent.

Over voltage protection

Under voltage protection

Earth leakage protection

Ground protection

Over-temp protection

Over load protection

Lightning protection


3. Output plug type.

Just check the charging interface of your EV.

Find out which type it is.

Usually it is one of following types:

Type 1 socket




4. Cables

Do not worry the electrical data of cable, it always compatible with the plug and control box already. We can pay attention to their physical characteristics like color, material .....
