There won't be (m)any like that, because the inbuilt power supply won't be capable of supplying the power required to charge at 10A. This is why the Bantam BC6 and such only have 50W of charging power, and a maximum current of 5A.
The closest I can immediately think of is the
Fusion LX61B, but that only charges at 8A, but has 90W of power when on 230V, and 120W when on 12V.
Really the best solution would be to get a decent 12V charger, and a proper power supply. I'd suggest these:
Chargers:
-
Fusion Paladin L120 Pro - this will charge at 10A, has two balance outputs (so it would be easy to charge two packs at once), and is capable of 180W when charging.
-
iCharger 206B - 20A charging at 300W, which allows for 4 and 5C charging easily.
-
iCharger 106B+ - 10A charging at 250W (which ensures that you can charge at 10A no matter how many cells are being charged (6S max). 2C charging would be allowed, and this would end up cheaper than the 206B, and probably the L120 too.
Power Supplies:
-
iCharger 350W PSU - you would need a standard AC power lead, as it would come from the US, but they are readily available. This would be the best option for the 206B, but not really required for the others.
-
Ripmax PSU - according to my calculations, this is capable of 276W output, so would definately be fine for the Paladin, but the 106B is more of a grey area.
