How to Match Charger Power to Your Vehicle's Charging Capacity

Last updated Aug 21, 2026

Match an AC charger to your vehicle’s maximum AC charging power, phase support and Type 2 inlet. For a DC charger, check the vehicle’s maximum DC charging power, CCS2 inlet and supported DC charging voltage. The specifications below apply to the European-standard dé products covered by the current manuals.

Important: Do not use the vehicle’s battery capacity in kWh to select charger power. Charger power is measured in kW.

Find the correct vehicle specifications

Check your vehicle manual or the vehicle manufacturer’s official specifications. Record the information that matches the charger category you are considering.

Charger category Vehicle information to check
Portable AC Charger or AC Wallbox Maximum AC charging power, single-phase or three-phase support, and Type 2 inlet
DC Wallbox Maximum DC charging power, CCS2 inlet, and supported DC charging voltage

The vehicle’s DC fast-charging figure cannot be used to choose a 3.7, 7, 11 or 22 kW AC charger. Look specifically for “Maximum AC charging power,” “AC charging,” or “On-board charger.”

Compare single-output AC chargers

The following Portable EV Chargers and AC Wallboxes use a Type 2 connection on the vehicle side.

Product family Product version Maximum power Power and phase specification
Portable EV Charger 3.7 kW 3.7 kW 230 V, 16 A, single-phase
Portable EV Charger 7 kW 7.36 kW 230 V, 32 A, single-phase
Portable EV Charger 11 kW 11 kW 400 V, 16 A, three-phase at maximum power
AC Wallbox with Cable 7 kW 7.4 kW 230 V, 32 A, single-phase
AC Wallbox with Cable 11 kW 11 kW 400 V, 16 A, three-phase
AC Wallbox with Cable 22 kW 22 kW 400 V, 32 A, three-phase
AC Wallbox with Socket 7 kW 7.4 kW 230 V, 32 A, single-phase
AC Wallbox with Socket 11 kW 11 kW 400 V, 16 A, three-phase
AC Wallbox with Socket 22 kW 22 kW 400 V, 32 A, three-phase

Note: A Type 2 charging cable is not included with the AC Wallbox with Socket. A separate Type 2 cable is required to connect the Wallbox socket to the vehicle.

Compare dual-output AC Wallboxes

For a dual-output charger, check the power available at each output rather than treating the combined product name as the power delivered to one vehicle.

Product Power configurations listed in the manual Power supply Vehicle connection
Dual 2x22 kW Wallbox with Socket 22+22, 22+11, 11+11, 7+7 or 3.5+3.5 kW 400 V AC, three-phase Two Type 2 sockets
Dual 2x11 kW Wallbox with Cables 11+11 or 3.5+3.5 kW 400 V AC, three-phase Two Type 2 cables
Dual 2x7 kW Wallbox with Cables 7+7, 7+3.5 or 3.5+3.5 kW 230 V AC, single-phase Two Type 2 cables

When comparing a dual Wallbox with a vehicle, use the listed power for the individual output that will charge that vehicle.

Compare DC Wallboxes

The dé DC Wallboxes covered by the current manual use a CCS2 charging connector. Check that your vehicle has a CCS2 inlet and that its DC charging specifications fall within the charger’s listed output range.

Product version Maximum power DC output range Vehicle connection
20 kW DC Wallbox Up to 20 kW 200–1000 V DC, 0–65 A CCS2
30 kW DC Wallbox Up to 30 kW 200–1000 V DC, 0–80 A CCS2
40 kW DC Wallbox Up to 40 kW 200–1000 V DC, 0–125 A CCS2

Do not use the vehicle’s AC charging rating to choose between the 20, 30 and 40 kW DC Wallboxes. Use the official DC charging specifications for the exact vehicle model, model year and sales region.

Complete the comparison

  1. Decide whether you need an AC or DC charger.
  2. Confirm the vehicle’s AC Type 2 or DC CCS2 inlet.
  3. Find the vehicle’s maximum AC or DC charging power.
  4. For AC charging, confirm whether the vehicle supports single-phase or three-phase charging.
  5. For DC charging, confirm the vehicle’s supported DC charging voltage.
  6. Compare the vehicle information with the applicable product table above.
  7. Separately confirm that the installation site has the power supply required by the selected charger.

Note: The figures in this article are charger specifications. They should not be presented as a guaranteed charging power or charging time for every vehicle.

If the vehicle specifications are unclear

Contact the vehicle manufacturer or dealer and provide the exact model, model year and sales region. Ask for the vehicle’s maximum AC charging power and phase support, or its maximum DC charging power, charging voltage and connector type.

For the charger specifications, review the relevant Portable AC Charger manuals, AC Wallbox manuals or DC Wallbox manual.
