NXT PSU (External Power Supply for NXT)
NXT PSU allows you to power your Lego Mindstorms NXT designs without using batteries. The NXT PSU was created to fulfill the need of having a regulated power source for a long period of time without the need of constantly swapping batteries.

The NXT PSU is an essential addition for anyone who are building static projects requiring a consistent power source. As the battery becomes weaker, the NXT Motor becomes inconsistent.

It would be especially useful for participants of the recent National Robotics Competition (NRC) or World Robot Olympiad (WRO), where participants in the open category always has stationary display projects.

Developed locally by "During Works" development team. Currently sold exclusively at Building Blocks.
