Ryobi TEK4 Batteries and Chargers
Ryobi is banking on their lineup of consumer focused TEK4 tools and the batteries that power them. They've diverged from the typical uses of power tool batteries and have branched out to create a convenient mobile phone/device charger that uses the same TEK4 battery that will power your cordless driver.
We show it above with the included USB attachment and this unit actually saved us during the Builders Show this year when at the end of the day our iPhone was on it's last legs. This backup battery charger got our unit from about 5% to almost 80% in about half an hour. It certainly saved us from being tethered to a wall outlet when we wanted to remain on the go at the show.
