How we picked
We compare products only on the specs published on each brand's own US store, with the date we checked. We don't list prices; each product links to its brand's page for the current one. We have not tested these units hands-on. Brands can't pay to be included or to change the order. If a brand ever sends us a unit, we'll say so.
A power station covers outages; your rate covers every other day. Check what you pay per kWh.
