Mobile Wallbox Buyer’s Guide: Choosing the Right EV Charging Solution

As a driver of an electric car or plug-in hybrid, you're faced with the question of how to charge your vehicle most efficiently. A permanently installed wallbox is one option, but it comes with installation costs and is often impractical for renters or frequent travellers. A mobile wallbox offers a flexible and high-performance alternative.

This article serves as a guide. It explains the key technical features of a portable EV charger and presents various models to provide you with a solid basis for making a decision that suits your individual needs.

What to Look for When Choosing a Mobile Charging Station

To find the right mobile charging station for your EV, several technical aspects are crucial. Understanding these parameters will help you select a device that matches your vehicle, your available power connections, and your daily routine.

1. Charging Power (kW) and Plug Types (Schuko, CEE)

The charging power, measured in kilowatts (kW), determines how quickly your vehicle's battery charges. It depends on the charger itself, the power connection used, and your EV's onboard charger.

• Schuko Socket (Household Socket): A Schuko charger uses a standard 230-volt household socket. The charging power is typically limited to a maximum of 3.7 kW. This option is convenient as Schuko sockets are widely available, but charging takes significantly longer.
• CEE Socket (High-Power Current): These connections allow for much higher charging outputs.
  • A CEE 16A charger (red, 5-pin plug) can provide three-phase charging and achieve a power output of up to 11 kW. A Mobile Wallbox 11kW is therefore a very popular choice for homeowners with the appropriate connection, as it offers a good balance between charging speed and grid compatibility.
  • A CEE 32A charger enables the fastest possible mobile charging with up to 22 kW. A Mobile Wallbox 22kW is ideal for vehicles with a 22 kW onboard charger but requires a corresponding 32-amp installation.

2. Safety Features and Standards

Safety is paramount when charging electric vehicles. High-quality mobile chargers, often referred to as ICCB charging cables (In-Cable Control Box), have a range of integrated protection mechanisms. Look for the following features:

• Residual Current Device (RCD): An integrated RCD (often Type A or the more comprehensive Type B) protects against dangerous fault currents and is an essential safety feature.
• Temperature Monitoring: Sensors in the plug and control unit monitor the temperature, automatically reducing the charging power or stopping the process in case of overheating.
• Protection Rating (IP Class): A high IP rating (e.g., IP66) ensures the device is protected against dust and powerful water jets, allowing it to be used outdoors even in bad weather.

3. Smart Control and Additional Features

Modern devices often offer more than just basic charging. A Smart EV Charger with App can significantly enhance convenience and efficiency.

• App Control: Allows for remote monitoring of the charging process, adjustment of the charging current, and scheduling of charging times.
• Scheduled Charging: You can set the charging process to start during off-peak hours with lower electricity tariffs (e.g., at night).
• Charging History: Some models log consumption data and charging duration, helping you keep track of your charging costs and habits.

Our Mobile Charger Recommendations

Based on the criteria mentioned, we have compiled a selection of mobile chargers that cover various use cases.

GONEO Portable Type 2 Charger – Schuko 16A 3.68kW

Why it stands out: This charger is designed for simplicity and safety when charging from a common Schuko household socket. It combines basic charging functions with comprehensive protection mechanisms.

Advantages:

• Comprehensive Safety: Equipped with residual current protection (RCD 30mA AC + 6mA DC), ground fault detection, and NTC temperature control, which reduces the current at 65°C and stops it at 70°C.
• Timer Function: Allows you to schedule the charging start time from 0–8 hours later, for instance, to take advantage of off-peak electricity rates.
• Easy Operation: The device remembers the last used current setting and displays charging data such as voltage, current, and temperature on an LED screen.
• High Compatibility: The Type 2 charging cable plug is compatible with all EVs and plug-in hybrids compliant with the IEC 62196-2 standard.

Who is it for? For EV drivers looking for a straightforward and safe solution for charging at home, at a friend's house, or as a replacement for a basic emergency EV charging cable, who primarily charge using standard household sockets.

feyree 11kW 16A Portable EV Charger with App Control

Why it stands out: This model combines the higher charging power of 11 kW with modern control concepts like a touchscreen and full app integration.

Advantages:

• Smart Control: Full control via the Tuya Smart app, including remote start/stop, adjustable charging current (8A-16A), charge scheduling, and a detailed charging history.
• Intuitive Operation: A 4.3-inch HD touchscreen made of tempered glass allows for clear and responsive operation directly on the device.
• High Safety Standard: Integrated Type B RCD (AC 30mA + DC 6mA) as well as over/under-voltage protection, lightning protection, and temperature monitoring.
• Future-Proof: Supports remote firmware updates (OTA) via the app to keep the device current with new features and optimisations.

Who is it for? For users with access to a CEE 16A high-power socket who want significantly faster charging than a Schuko outlet and value smart features, data control, and a modern user interface.

feyree 22kW 32A Portable EV Charger with Wi-Fi & App

Why it stands out: This charger offers the maximum available mobile charging power at 22 kW, aimed at users who want to reduce charging time to a minimum.

Advantages:

• Maximum Charging Power: With up to 22 kW (32A, 3-phase), compatible vehicles can be charged extremely quickly.
• Flexible Current Adjustment: The charging current can be set precisely both on the device (in steps from 8A to 32A) and continuously via the Tuya Smart app.
• Comprehensive App Features: Offers all the benefits of a Smart EV Charger with App, including charge scheduling, cost savings by charging during off-peak hours, and status monitoring.
• Focus on Safety: Features an emergency stop button, a Type B RCD (AC 30mA + DC 6mA), and a waterproof rating of IP66.

Who is it for? For drivers of electric vehicles with a 22 kW onboard charger who have regular access to a CEE 32A industrial socket and want the fastest possible mobile charging option without installing a permanent wallbox.

Frequently Asked Questions (FAQ)

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

An emergency EV charging cable, often called an ICCB cable, is typically designed for slow charging from a low-power Schuko socket. A mobile wallbox is more versatile: it often provides higher charging power (e.g., 11 kW or 22 kW via CEE adapters), advanced safety features like a Type B RCD, and smart control options via an app.

Can I charge my EV from any socket?

In principle, charging an EV from a socket is possible, but the type of socket determines the speed and safety. A Schuko socket is not always designed for continuous high loads and should only be used at a reduced current and after being checked by a qualified professional. CEE sockets (high-power current) are designed for high continuous loads and enable much faster and safer charging with a compatible portable EV charger.

How fast does a mobile wallbox with 11 kW charge?

A Mobile Wallbox 11kW delivers 11 kilowatt-hours (kWh) of energy to the vehicle's battery per hour. An electric car with a 55 kWh battery capacity would theoretically take about 5 hours to charge completely from 0 to 100%. In practice, the charging time can vary due to factors like battery temperature and the vehicle's battery management system.
