This transformer is intended for use with our 1.2GHz wireless cameras.  It's plug end will plug directly into the wireless receiver.  The output plug is 2.1mm x 5.5 female center positive.  If you want to power both the camera and the receiver, then you will need two of these.  The wireless cameras sometimes have a 1.3mm plug and you would have to splice the ends to fit the camera.

We recommend using our peak charger so you do not overcharge and damage your batteries.  The higher the mA, the faster the battery will charge.  If you use too low of a voltage transformer, the battery won't fully charge.  If you use too high of a voltage transformer, the battery or transformer will be damaged.  The table below is a chart that can be used to safely and effectively select the right transformer to charge your batteries.
