Powerpack or Stayalive Energy buffer!!!
A Powerpack or Stayalive is the solution for DCC to avoid running and sound interruption while driving your model. Once the power on the track is switched on, the supercapacitors of the powerpack/stayalive start charging. When the locomotive experiences power loss, because of dirt on the track or on a frog of a point (switch), the stayalive kicks in and assures the loco will continue for a few seconds. Let’s look at the difference of the two, as they are often seen as similar. Here are the differences:
Power Bridge I & II
– The NixTrainz Power Bridge I & II can be wired as a 3 wire power pack or 2 wire stay alive.
– Has 3 wires to be compatible with power pack suitable decoders. The white wire is a data cable, through which the Power Bridge is switched off when compatible decoders are being programed.
– Can be configured to be a 2 wire stay alive by combining the white with the red wire to U+.
– Has one super capacitor.

Which one is best for you?
It all depends on the space. If you have enough space choose the Power Bridge I or Power Bridge II. They will provide faster charging and superior back up power.
If space is a concern, choose the Power Bridge III. Its small size and separable mounting allows it to fit in really tight spaces, even in “N” scale. The 3-6 seconds of extra power from the Power Bridge III will be more than adequate to get the locomotive over problem areas.
