I have a handyman working in my new (to me) condo this week, and I’ve noticed his Android phone gets some use. If he needed, he could get a recharge by plugging his phone into a outlet in my house, but what if he were working on a construction site that may not have a power outlet he could use? Instead of carrying a backup battery or keeping a bulky battery case on his phone, he could just keep the PoweriSite charger in his pocket and top off his phone from any Dewalt power tool battery. This Kickstarter device provides 3.1A, so you can charge a tablet, too. Funding continues through Thursday Dec 19, 4:09am EST; delivery is expected in March 2014, if successful. A minimum pledge of $12 (early bird special price) gets you an PoweriSite.
