Description
If you own a MacBook, you'll recognize this little friend. The premise of this 2.1mm DC Barrel Jack to
2nd Generation MagSafe Adapter 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 2nd gen. 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.
We also offer a version with a 1st generation MagSafe plug.
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!
