Note: No 3-pin sockets: USB and 12 V car socket only. Jackery says it cannot power household appliances.
Why it's worth a look
- battery rated for 4,000 cycles: over 76 years of weekly use.
- Light at 2.5 kg: easy to carry from the car or up the stairs.

Watch out for
- No mains (230 V) sockets: USB and 12 V only, so no fridge, kettle or laptop charger plug.
- No published switch-over time, so it may not keep a computer or CPAP running through a power cut.
