| Kitchen appliances | Runs a microwave or hairdryer, but not a full-power kettle |
|---|---|
| Power cut | About 25 hours of fridge-freezer, router, two lamps and phones |
| Carrying | 20.3 kg: two people or a trolley for stairs |
| Recharging | Full from the mains in about 68 minutes; solar up to 500 W |
| Medical and sensitive kit | No published 10 ms switch-over: not for a CPAP machine |
| Growing later | No add-on batteries |
| Saving money | Buy it for backup, not savings: charging overnight at about 8.5p and using the power by day would save about £113 a year, before battery wear |

Why it's worth a look
- Keeps a fridge-freezer, router, two lamps and phones going for about 25 hours in a power cut.
- Takes up to 500 W of solar, so it can refill in a long cut or off-grid.
Watch out for
- Can't boil a 3 kW kettle (2,400 W output).
- No published UPS switch-over time, so it may not keep a computer or CPAP running through a power cut.
- Heavy at 20.3 kg: think about who will move it.
- Battery life () not published.
- Warranty length not published on the UK page.
