The portable charger for electric vehicles is a portable device that enables you to just plug the device into the natural power socket and the battery will be charged. It can be easily carried by you, so you will not be troubled with a way of recharging the battery when away from home or charging station.

Portable EV chargers work by drawing power from an external source, such as a standard wall outlet (Schuko) or an industrial CEE socket. The portable charger check and regulates the voltage and current for charging an electric vehicle.

It is pretty straight forward.

1. Prepare your power source. If you use Schuko socket make sure it can withstand continuous high load (13+A). For 3.6 kW charging ensure you have a cable section with at least 2.5mm2. The recommended cable section for 7 kW charger (32A) is 6mm2.

2. Connect your charger into the power source

3. Connect the charging gun into your EV

4. Charging should start immediately as long as your battery is not full and there are not set timers.

The best "EV charger" is the safe one. Ensure it has the necessary certification and protections (such as leakage, over-heating, grounding, etc). Pay attention to the RCD (residual current device) of the charger. Some regions require an AC<30 mA + DC<6 mA. Cheaper chargers have Type A AC <30 mA

It depends on two factors: what is the capacity of your battery and what is the power of the charger.

The fastest scenario is using a Level 2 (22 kW) charger with a small battery (Renault Zoe for example). It will take 1 hour and 15 minutes to fully charge the Renault Zoe Q210 on AC!

A slow scenario is charging a Tesla Model Y Long Range on a Level 1 (13A charger). Tesla's 75 kWh battery will take around 30 hours for a full charge.

Most EV drivers aim for an 8 hour charge, within the 10-80% range.
