11 kW or 22 kW wallbox: which one your car and fuse box can use

The two go-e boxes here cost €819 for 11 kW and €829 for 22 kW, at go-e's German shop, checked 2 November 2026. Other countries differ. On price alone you'd take the bigger one.

Don't. The price of the box isn't what separates them.

Your car decides first

The car's onboard charger sets the limit on AC. Plug a car with an 11 kW charger into a 22 kW box and you get 11 kW, as both Ingenieur.de and go-e point out. Hyundai's German list gives the Ioniq 5 Centriq a maximum of 11 kW on AC.

go-e's list of cars that accept 22 kW includes the Renault Zoe, Volvo EX30, Toyota bZ4X and BMW iX3. Check the exact version, because go-e also notes some Audis have it only as an option.

When the car can take it, go-e's own table gives 5.5 hours at 11 kW and 2.7 hours at 22 kW for a 60 kWh battery. Those are simple divisions, not measurements. Overnight, both finish.

Then the fuse box

11 kW draws 16 A on each of three phases. 22 kW draws 32 A, go-e says. That means a bigger circuit, and the house connection has to be able to spare it. An electrician should check this before you order anything. That's their job, not a weekend one.

Then the country

I read this on November 2, 2026. These rules move, so treat the table as a starting point for your installer. Several sources are charging firms, not regulators.

The Dutch figure stings. ANWB says going one level above the standard connection costs about €1,000 a year extra.

What go-e's shop says, and what it doesn't

Here's the odd one. go-e's German shop says that "aufgrund gesetzlicher Bestimmungen", because of legal provisions, the Gemini 2.0 22 kW may not be used in the Netherlands, France, Italy or Spain. Its 11 kW page says the same of the 11 kW in the Netherlands, France and Italy. So Spain is the only one of the four where go-e allows the smaller box. Zerofy, citing the data sheet, says go-e's box isn't approved for the Netherlands, France or Italy.

That's all that's documented. go-e names no law. I looked for a national ban on 22 kW home charging in those four countries and found none, and the Dutch, French, Italian and Spanish pages above treat it as an option if the supply allows. That doesn't prove there's no rule. The 11 kW box is on the list too in three of the four, so power can't be the whole reason there.

For France there's one clue. go-e sells a separate CORE T2S with a shutter in the Type 2 plug, which it says is required in France. It doesn't link that to the Gemini.

So don't read this as a ban on 22 kW wallboxes. It's a limit go-e states for these models, and my reading isn't a legal finding. If you live in one of the four, ask your installer which box is approved there before ordering from a German shop.

What I'd do

Buy 11 kW if your car stops at 11 kW, which goes for the Ioniq 5 and many others, or if you charge overnight. Ingenieur.de reaches the same answer for most homes.

Go to 22 kW only with a car that takes it, a short overnight window or two cars sharing one point, and a supply your electrician has signed off. The rest is explained in single-phase or three-phase, and my wallbox picks cover boxes from other makers. Both go-e models are listed under home chargers.
