The question of choosing the right charger is relevant for every owner of an electric car or hybrid.

To make the right choice, it is important to understand what types of charging for electric cars are divided into public, private stationery, and mobile (portable). Portable electric charging from a regular household outlet usually comes with a car.

In this article, we will take a closer look at the newest type – portable EV chargers.

Portable EV chargers come with greater power and recharging speed, like emergency chargers.  A portable EV charger comes in the list of Level 1 Electric Vehicle Supply Equipment (EVSE) as it has the ability to charge at low power.

They can charge up to 32A and, in some cases, with a three-phase network, thus reaching up to 22kW and a good charging speed. On the other hand, charging at 32A requires industrial sockets, which are not common in homes.
