Charger advice

[Peakey]

I'm now looking for a quad charger as my lipo stash and cars are expanding. I'm after one that will work off mains and 12v battery, and if I can get away without a psu that would be good but not a big problem if not. I've been looking and found these that seem reasonably priced

Dose anyone have either of these or can recommend something that's simmiler or the sort if thing I should be looking for.

Thanks justin
