Power where there is none — at the allotment, in a camper, on a shoot, and at home when the mains goes down.

A 512 Wh reserve is roughly 7 hours of laptop, 5 hours of a cool box, or 29 full phone charges. At 500 W it runs equipment that normally needs a wall socket. With panels it charges at up to 11 W — one sunny day and the reserve is back. It weighs 6 kg, so it carries in one hand.

In short

• Capacity: 512 Wh
• Continuous output: 500 W
• Solar input: 11 W
• Weight: 6 kg
