Build Your Own Adapter For Cheap Mains Power on Portable Devices

If you’re looking for a way to build a battery-to-wall-power adapter for one of your portable devices, this tutorial can serve as a template for your DIY adventures.

Mike Worth wanted an outlet adapter for his Canon camera, but Canon wanted $75 for it. Not looking to spend that kind of cash on a very simple adapter, he set out to build his own.

The build is quite simple, consisting of a transformer with the proper voltage, and a set of dummy battery casings with thumb tacks and washers to serve as the negative and positive leads. Hit up the link below to see the full build.

Making a Mains Adapter [via Hack A Day]

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    For those that don’t speak the Queen’s English, “mains power” is “AC wall outlet power.”

    WHERE do you get the connector that the power brick PLUGS into??? I have searched high and low but power bricks I have different sizes from very skinny to the big & fat and the kind the laptops use.

    a reply to my email add would be appreciated.

    I use to build stuff like this but then found ebay had them for under $10
