Quick answers

Common questions

How are the reviews organised?

By battery size: compact stations under 1 kWh, mid-size stations from 1 to 1.5 kWh, large stations from 2 to 3 kWh, and whole-home stations of 3.5 kWh and up. You can also browse by brand.

How are the runtimes in each review calculated?

We multiply the battery capacity by 85% for devices on AC outlets (92% on a DC or USB cord) and divide by the device's average draw. Treat the results as planning estimates: cold weather, battery age and idle draw all shorten real runtime.

Where do the specifications come from?

From each product's official specifications, product page or manual. We re-check them whenever a review is updated, and a review says so whenever a unit has been tested hands-on.

What is in every review?

The key specs and what they mean, wall and solar charging speed, runtime for common appliances, what the station can and can't run, backup switchover, how it compares with similar models, and who should buy it or skip it.
