Most people buy a power station the way they buy a suitcase: they pick the one that looks serious, then hope. A weekend away only needs the watts you will actually use. Here is the short version we use on the shop floor.
Start with the devices, not the brand
List what must stay on if the grid drops or the campsite has no hookup. A phone charger is nothing. A 12V fridge, a laptop and a couple of lights are the usual trio. Add the watts printed on each device, then the hours you want them running.
Watt-hours you need = watts × hours. Then add about 20 percent so you are not landing on empty at dusk.
A useful rule of thumb
- Under 300Wh — phones, a camera battery and a light. Fine for a day hike, thin for a night.
- 500–1,000Wh — a laptop, a drone charger and a small fridge for a night or two.
- 1,000Wh and up — weekend cabins, CPAP machines, or anything you cannot afford to shut off.
What we look at before we recommend one
Output matters as much as capacity. A station can hold plenty of energy and still refuse a fridge compressor if the surge watts are too low. Check the AC outlets, the solar input if you plan to top up, and whether the battery can be expanded later. EcoFlow, Bluetti, Anker SOLIX and Jackery each do that differently — we will match the box to the trip, not the other way around.
If you already know the fridge model, send us a photo on WhatsApp. We will tell you the smallest station that will actually start it.
