yes. i got a generic one.I had those batts and they worked on a canon charger but not a third party charger.. total chaos for any one assisting me.
"yep do the charging please.. but charge the canon batts on the non canon charger and the wasabi batts on the canon charger"
Just so much simpler to power from a 12v source and only use 5d batteries for a 5d.
the smallhd one (DCA5) i thinks is a better design but price is ridiculous at $140
indipro one looks like a good alternative
