NEW PRODUCTS – 2.1mm DC Barrel Jack to MagSafe Adapter: 1st & 2nd Generation


If you’ve ever owned a MacBook, you’ll recognize these little friends. The premise of these 2.1mm DC Barrel Jack to MagSafe Adapters is simple. There’s a MagSafe plug on one end and a 5.5mm/2.1mm DC barrel jack with center positive polarity on the other. This allows you to connect a 15-20VDC power supply to something that expects to connect to MagSafe.

Since you can easily destroy hardware using this adapter, we really recommend it only for experts and people who fully understand what they’re getting into by pushing arbitrary voltages into their fancy computers! Use a multimeter to probe the magjack pins to verify you’ve got the right voltages before plugging in into your computer.

Available in both 1st Generation and 2nd Generation MagSafe versions.

There is no regulator or voltage protection in this adapter. If you plug in an incorrect power supply or wire it backwards, you could destroy your laptop – so be really careful!

  1. Great idea. The plastic looks molded on. May a good candidate for a small fuse and blocking diode to help prevent mishaps. Good job!
