Adding wireless charging to any phone

June 19th, 2013, 22:25 Posted By: wraggster


The wireless charging options available on flagship phones is a great feature, but most of us aren’t rocking the latest and greatest cellphone. [Daniel] came up with a great mod thatadds wireless charging to just about every cellphone ever, at a very low price and a few bits and bobs ordered off eBay.
[Daniel] used a Palm Touchstone inductive charger – available for a few bucks on eBay – along with an inductive charging circuit from a Palm Pixi. This charging circuit was designed to complement the Touchstone charger, and is simple enough to wire up; all [Dan] needed to do was put the coil and charging circuit near the charge, and it output 5 Volts to charge any phone.
To get the power from the charging circuit into his phone’s battery, [Daniel] simply wired the output of the coil’s circuit to the USB in on the phone. The space inside his S2 was pretty tight but he was able to come up with two ways to install the charging circuit, for use with either the stock back cover or a third-party case.
For anyone with a soldering iron, it’s a quick bit of work to add wireless charging to any phone. We’re loving [Dan]‘s solution, as the Palm gear he used is so readily available on eBay and junk drawers the world over.
