has anyone tried this out http://www.ebay.com …place-LP-E8-/181169277786
the seller tells me that it will convert incoming voltages to the appropriate voltage for the LP-E8, i just wanted to see what other peoples experiences were with this device? I would like to convert 12 volt to 7.2 volt on the LP-E8 to power it for long periods of time in the field and reduce heat build up inside the T2i.
