Portable power station
A portable power station is a self-contained battery unit with its own sockets, usually with an inverter that supplies mains-style power from the stored energy. It lets you run some items without a campsite connection, within the limits its maker states.
Where you'll see it
You'll find these on camping and outdoor product pages, often with a capacity and an output figure. Capacity tells you how much energy is stored, and output tells you how much power it can supply at once. Read both before you compare models.
What to check
- The capacity in watt-hours (Wh) and the output in watts (W), with the units clearly stated.
- The list of sockets and ports, and what the maker says each one is for.
- The charging options and charging times the maker gives.
- The maker's instructions for use and storage, including where it should and should not be used.
