One Year Goof Proof Warranty
All TCS Keep Alives are covered by a one year goof proof warranty.

TCS Keep-Alive® (KA) devices are used to supply power to decoders during times of power interruption due to dirty track or problematic track work. The KA-N1 can power an N-scale locomotive for 1-2 seconds over dirty track and power interruptions (depending on the number of lights and efficiency of the motor).
 
This Keep Alive® has been specifically designed to be as physically small as possible. This product uses a slightly lower voltage and has a lower capacity compared to our larger Keep Alive products such as the KA1, KA4, etc., and is intended to be used with N-scale decoders, such as the K7D4 and more!
