A while back, I went w/the skil 12v pwrcore platform in part because they had USB outputs in their batteries and chargers. Recently I've gotten a few USB charging li-ion tools for convenience and some declutter. Seems like these devices are perfect to keep inside the house or the glove box.
I must not be the only one thinking it as I see Ryobi released a line now (soldering iron, box cutter, screwdriver, foam cutter, glue gun, etc...). These are mine so far:
Rotary tool turned tungsten grinder & screwdriver kit. pwrcore 12 batteries to power usb devices (mostly used as phone batt. bank)
