Why use one?
Your layout will occasionally suffer from dirty track or small electrical dead spots at points and crossings. The small loss of power can cause locomotives to stop, but with DCC Sound Decoders it can also cause the sounds to reset and restart. Avoid both issues by fitting a Power Bank.
Perfect locomotive running and optimal control!
(The Power Bank is not suitable for use without an HM7000 decoder, connecting it directly to other decoders or directly to the wiring of a model locomotive may cause damage to the Power Bank, your locomotive or your non-HM7000 decoder).
For small locomotives we have a smaller Power Bank available R7377 Power Bank
