This revolutionary power supply from FK Irons can be connected to any RCA machine - as long as the RCA socket is not blocked. Its compact design is ideal for easy travel and takes into account the ergonomic balance point of the machine. Weighing only 58g, the UNI Lightning Bolt is small but can still power the machine for up to 10 hours - depending on the voltage.

Intuitive and easy to use, the UNI Lightning Bolt has a 5 - 12 V output with 0.5 or 0.1 volt intervals and features a quick charge function.
Its compact design allows the machine to balance forward. In most cases, the machine feels lighter than when used with standard cables. Experience a whole new freedom of movement while going completely wireless and having plenty of juice to do it with.
