A workshop filled with batteries is also a workshop filled with power tools. The new power tool system from Ryobi allows them to share the charging ports for their phones, tablets, and laptops.
The 4V, 2.0Ah batteries have a built-inLED so they report their charging status while plugged into a cable. The batteries can't be used to charge a mobile device through that port nor can they provide enough kick to power a new line of tools geared towards home maintenance.
The new $60 Dremel-like power carving tool uses chisel-shaped tool heads that move back and forth with a millimeter of travel, and is powered by the $20 batteries. Those are joined by a $60 power cutter with a self-sharpening blade that looks like an upgraded version of those cutters designed to easily tear open plastic blister packaging, but can handle other thin materials. The Twist Driver is a screwdriver with a mid-handle pivot that converts it from an inline to an angle driver.
There are currently no details on run times, charge times, or when the newusb lithium will be available, but they are expected to arrive sometime this spring, and will only be available at Home Depot's brick-and-mortar stores. You can probably find a few of those floating around a drawer after years of owning a phone.
