Chargers for Opel

The Opel range has four levels of onboard power, so the match depends on the version. Of 51 versions, 25 have 7.4 kW and get a Q74 or a portable P72, 13 have 11 kW, meaning a Q11 or P11, and 12 have 3.7 kW, meaning a Q37 or P35. One, the oldest, has 3.3 kW.

Yes, but it is an exception. One of the 51 versions in our database, from the oldest model years, has a Type 1 connector and 3.3 kW of onboard power. For it we match the 3.7 kW B35. The other 50 versions use the standard Type 2 connector.

Because 25 of the 51 Opel versions in our database have 7.4 kW onboard. That is the largest group in the whole range, which stretches from the 2012 to the 2026 model year. For those cars the correct choice is the 7.4 kW Q74, not a more powerful unit. If you prefer a display to app control, the equivalent is the P72 at the same power.

The largest pack in our data holds 96.9 kWh. At 11 kW that is around 9 to 10 hours; at 7.4 kW it grows to roughly 13 to 14 hours. The smallest battery in the Opel range holds 11 kWh and fills at 3.7 kW in around 3 hours.

The match is decided by onboard power, not drivetrain type. The Opel range holds 13 plug-in versions and 38 electric cars, with powers spread from 3.3 to 11 kW. If your version has 3.7 kW, a Q37 is right. At 7.4 kW we reach for a Q74, because a Q37 would double the charging time.

There is no point. The highest onboard power across the whole Opel range is 11 kW, so a Q22 would never deliver more than half its capability. Buying spare capacity will not shorten charging by a minute. The upper limit of a sensible match for this brand is a Q11 or P11.
