PoweriSite Turns Your Power Tool Batteries Into A USB Charger

While contractors/builders will never leave home without their tool battery packs, they will forget to bring their phone chargers.  The PoweriSite is trying to address this problem by turning your cordless tool battery packs into a USB charger for your other gadgets.  This only works if you have the USB cable with you but let's not overthink this one.  Pre-order yours for $17.95 (shipping March 2014).
