I didn't say it wouldn't work, I said as you can see was with 120w you cannot efficiently charge a leisure battery.
Yes 10A would not be enough to be worthwhile. Luckily, many vans do have 20A lighter sockets. A quick google show that most Ford Transits have 20A ones, whilst most Fiat Ducatos have 15A (sometimes with an additional 10A one). Mercedes Sprinters seem to have a mixture of 15A and 20A (occasionally some are 25A on a Maxi-fuse). All these things vary from year to year and model to model. However, very few seem to have only 10A sockets.
