Wallbox Buyer’s Guide: Choosing the Right Home EV Charger

As an electric car owner, you face the decision of how to charge your vehicle at home most efficiently and safely. The range of charging stations is vast, from permanently installed units to flexible mobile solutions. The technical differences, especially in charging power and feature sets, can make the choice challenging.

This guide, written by the Joybuy Product Recommendation Officer, is intended to provide you with objective guidance. We will explain the key criteria for selecting a wallbox and present a selection of different models to help make your decision easier.

What to Look for When Buying a Wallbox?

Three central aspects determine which charging solution is right for your needs: charging power, form factor, and feature set.

1. Charging Power: 11 kW or 22 kW Wallbox?

The charging power, measured in kilowatts (kW), indicates how quickly your vehicle's battery can be charged.

• 11 kW Wallbox: This is the common standard for private use. In Germany, such a charging station only requires registration with the responsible grid operator. It offers a good compromise between charging speed and grid compatibility for most households. A full charge for a typical EV usually takes between five and eight hours.
• 22 kW Wallbox: This more powerful version cuts the charging time in half but requires a permit. The grid operator must approve the installation, which is not always granted if the local grid capacity is insufficient. Additionally, the vehicle itself must support 22 kW charging via alternating current (AC), which is not the case for all models.

2. Form Factor: Fixed Installation or Mobile Wallbox?

The choice between a permanently installed and a mobile charging station depends on your usage patterns.

• Permanently Installed Wallbox: This is permanently mounted on a wall (e.g., in the garage or carport). It is a convenient and robust EV charging station for home. The installation must be carried out by a qualified electrician.
• Mobile Wallbox: A mobile charging unit offers maximum flexibility. It can be used in various locations with suitable sockets (e.g., a red CEE industrial socket or a standard household socket). This makes it ideal for people who also want to charge their vehicle at a friend's house, a holiday home, or while travelling.

3. Smart Features: App Control and Load Management

Modern charging stations offer useful additional functions that make the charging process more convenient and cost-effective.

• Wallbox with App Control: The charging station can be connected to a smartphone app via Wi-Fi or Bluetooth. This allows for remote monitoring of the charging process, adjusting the charging current, scheduling charging times (e.g., at night for cheaper electricity tariffs), and analysing consumption data.
• Charging Station with Load Management: Dynamic Load Balancing (DLB) is particularly relevant in households with other large electricity consumers (e.g., heat pump, instantaneous water heater). It measures the total power consumption of the house and dynamically adjusts the EV's charging power. This prevents an overload of the home's electrical connection while ensuring the vehicle is always charged at the maximum available power.

Frequently Asked Questions (FAQ)

Does an 11 kW wallbox need to be approved?

No, in Germany, a wallbox with up to 11 kW of charging power does not require a permit. However, it must be registered with the local grid operator before use. Charging stations with more than 11 kW (e.g., a 22 kW wallbox) require prior approval from the grid operator.

What is the difference between a mobile wallbox and a charging cable?

A simple Type 2 charging cable connects the car to a public charging station or a wallbox. A mobile wallbox, on the other hand, is a complete charging device. It contains the control and safety electronics in a control box and connects directly to a CEE or household socket to charge the vehicle.

Can I install a wallbox myself?

For safety and warranty reasons, the installation of a permanently installed wallbox must be carried out by a certified electrician. They will check the home's electrical connection, install the necessary circuit breakers, and ensure that all standards are met. Mobile chargers that connect to an existing and correctly fused socket do not require such installation.
