About

ColdWatt exists because winter power is a different problem. Most portable power advice is written for summer camping in mild climates. It rarely mentions that many lithium batteries can't be charged below freezing, or that a unit left in an unheated garage might shut off in the middle of an outage. Where we live, that's the whole question.

Who's behind it

ColdWatt is run by one independent editor based in Alberta, Canada. Guides are published under the byline ColdWatt Research.

ColdWatt Research is the byline for guides published by ColdWatt, an independent site run by a single editor in Alberta, where winter nights regularly drop below −30°C. Guides are researched from manufacturer specifications and public safety sources, with every source linked so you can check the work.

What you'll find here

  • Free tools — a winter runtime calculator and a database of cold-weather specs for popular power stations.
  • Buying guides — picks for specific winter situations, with the reasoning shown.
  • Home backup and cabin power guides for planning a setup that works when it's −30°C.
