Sorry if this has been discussed.. I couldn't find any good sources on the site. If someone wants to redirect me to something good.. that'd be great! Otherwise I was wondering if anyone can vouch for this power supply: Schumacher PORTABLE POWER CHARGER 22 Amp/Hour BATTERY : eBay Motors (item 390173720944 end time Mar-29-10 19:30:54 PDT) I want to be able to hook up work lights for outdoor shoots @ night. It's the cheapest way for outdoor light as far as I know, and i'm looking for something to power them if my extension cord doesn't reach any nearby outlets. If there are any better ones then this, please also tell me. Also, i'm up for any suggestion for night time shots. Thanks!
