Frequently asked questions

Introduction

What are portable chargers for electric cars?

Portable electric car chargers are compact devices that allow EVs to be charged in a variety of locations, regardless of access to dedicated charging infrastructure. They connect to standard domestic or industrial sockets or dedicated charging points, making them a convenient solution in many situations.

Why is it worth having a portable charger?

Having a portable charger gives EV drivers greater independence and security, especially when travelling and in areas where public charging stations are limited. It’s also a good solution for people living in multi-unit buildings or renting flats that don’t have access to a dedicated charging point.

2 Types of portable EV chargers

Home socket chargers (Level 1)

This is the simplest and most common type of charger that can be plugged into a standard 230V socket. It offers low power (typically 2.3 kW), so it can take several hours to fully charge the battery. Ideal for people who leave the car overnight and do not need a quick charge.

Chargers powered from a power socket (Level 2)

Level 2 portable chargers use three-phase connections, allowing charging with up to 22 kW of power. This is a significant difference compared to Level 1 – it takes a few hours instead of several hours to charge a battery. However, they require access to a power socket (e.g. CEE 16A, CEE 32A).

Portable DC chargers – do they exist and how do they work?

Portable DC chargers are not yet widely available, as they require very high power and powerful electronics. There are, however, solutions that allow the use of external batteries for emergency vehicle charging with up to 30 kW of power, but these are expensive and mainly used in professional applications.

3 Key parameters for portable chargers

Charging power and top-up time

The higher the power of the charger, the faster the battery can be topped up. Standard values are:

• 2.3 kW (Level 1) – approximately 10-20 hours for a full charge
• 7.4 kW (Level 2, single-phase) – approx. 4-8 hours
• 11-22 kW (Level 2, three-phase) – approx. 2-6 hours

Plug types and their standards (Type 1, Type 2, CCS, CHAdeMO)

The most common standards are:

• Type 1 – mainly in older EV models (USA, Japan)
• Type 2 – predominant in Europe
• CCS (Combo 2) – enables DC fast charging
• CHAdeMO – mainly used in Japanese cars (e.g. Nissan Leaf)

Energy efficiency and current losses

With AC charging, there are some energy losses due to the conversion of AC to DC current in the car’s on-board charger. Good quality portable chargers minimise these losses, achieving efficiencies of 90-95%.

4 When is it worth buying a portable EV charger?

Use scenarios – travel, emergencies, charging in rented accommodation

A portable charger is the ideal solution for:

• Travellers – allows charging in hotels, campsites or friends’ homes
• People renting flats – no need to install charging stations
• EV owners without a permanent parking space – can charge in various locations
• Fleet users – provides additional flexibility in vehicle management

Differences between private and fleet users

For private users, it is all about convenience and the ability to charge in different locations, while for fleets, portable chargers provide a way to optimise costs and flexibility in vehicle management.
