* The HM7070 Power Bank has now been made smaller to fit into even more locomotives, whilst still providing an ample amount of stay-alive energy for optimal control.

The HM7070 Power Bank will keep locomotives running over any potential dead spots. It works in a similar way to 'stay-alive' or capacitors which are available from other manufacturers.

The HM7070 Power Bank can be connected into the current range of HM7000 DCC Bluetooth decoders. A simple plug & play socket means there's no soldering required!

(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).
