Ryobi Portable Power Clip

Here's one of the ultimate functional designs, a battery clip for the Ryobi One batteries that provides 18V output wherever you need it. Combine this with a 5v USB regulator from Amazon ($3.99 - http://www.amazon.com/gp/product/B00CPYYAFA?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s01) or a variable power and current supply module (http://www.amazon.com/gp/product/B00OZGVL4O?keywords=adjustable%20power%20regulator&qid=1449899295&ref_=sr_1_4&sr=8-4) for one rechargeable, portable power supply. Most laptops run on that same voltage, making this an ideal option for laptop and tablet power. To customize the setup, I added pigtails to the battery clip, allowing me to switch between different modules easily. My current applications include attaching the variable voltage module and setting it to 7.2 volts for a backpackable power supply, and using it with my Sony a55 digital camera. When the camera's on a tripod (using a printable iPhone tripod mount), I also use the setup to charge my iPhone for continuous video recording.
