Texas-based Tindie seller 3DPStuff has launched an interesting add-on for anyone invested in Ryobi's popular One+ cordless power tool ecosystem: an adapter which adds USB Quick Charge outputs to any Ryobi One+ battery.
"I saw few solutions on Thingiverse to create some sort of power supplies using Ryobi batteries," 3DPStuff explains of the inspiration behind the project, "but none used a proper PCB and spring loaded battery connectors, so I gave it a try." The result is an adapter board plus step-down module which takes its power in from the Ryobi One+ battery and outputs 5V for USB devices and up to 12V for Quick Charge 3.0 compatible hardware.
The design offers a claimed 90 to 97 percent conversion efficiency, offers input over-voltage and under-voltage protection, output over-current and short-circuit protection, and over-temperature protection. It also offers a selection of fast-charge standards. While built with Qualcomm's Quick Charge 3.0 in mind, it's backwards compatible with Quick Charge 2.0 as well as BC 1.2, Apple's iPhone fast charging standard, MTKPEI 1 and PE 2.0, the Fast Charge Protocol, Star Fast Charge Protocol, AFC, and SFCP.
The design isn't 3DPStuff's first aiming to give power tool batteries a newfound flexibility: the store also stocks barrel-connector adapters for both the Ryobi One+ battery family and DeWalt's rival standard.
The adapter, including PCB and 3D-printed housing, is available now from the 3DPStuff Tindie store priced at $25.
