Hi guys! So I thought it'd be pretty cool to be able to run power directly from my truck on carpentry jobs, tools like circular saws, big drills, reciprocating saw, stuff like that. Impulse buy- I went to lowes and picked this up: http://www.lowes.com/pd_328619-8960...l=1¤tURL=?Ntt=power+inverter&facetInfo= now I'm kinda having second thoughts. 1) Do I need the truck idling whenever I run power using this unit? Can I charge, say, my laptop, hooked to this, while I'm driving? 2) Is there "hardwiring" available, or do I have to pop the hood and hook up to the truck battery every time I want power? 3) Could I keep the clamps connected to the battery, tuck the inverter somewhere under the hood, and keep it all just plugged in? Or that would drain the truck, right? 4) have to wire it all up just to print something off my portable printer while on the road? Just having some doubts... I can return no problem if there's something better out there. Opinions and insights would be appreciated!
