1Location optional — for solar sizing

Used for peak sun hours at your location, from five years of local weather. Leave blank for a conservative national average (4 hrs).

2What Are You Powering?
240V device detected. Most portable power stations output 120V only. Devices marked 240V (dryers, well pumps, central AC, L2 EV chargers) won't work unless the station supports 240V bonding, which typically requires two units plus a bonding cable.
3Duration & Pattern
Yes — pair with solar panel

Solar panels add weight and cost but can recharge your station during the day, extending runtime for multi-day trips.

How we make money: Every buy button below is an affiliate link. Some go straight to the manufacturer's own store, through that brand's affiliate program — the button says which shop it opens. The rest go to Amazon, where as an Amazon Associate Redo Energy earns from qualifying purchases. Neither costs you anything extra. Where a manufacturer link exists we still list Amazon underneath it, even though Amazon usually pays us less, because you may simply prefer to buy there. We don't surface a product unless the calculator scored it for your situation, and nothing is ranked by commission.
