FAQs

What size power station do I need?

Match watt-hours to the job: ~250–500Wh runs phones, laptops and lights for a weekend; 1,000Wh+ handles a cool box or power tools; 2,000Wh+ approaches home-backup territory. Check the continuous output (W) covers your highest-draw device, not just the capacity.

LiFePO4 or standard lithium-ion?

LiFePO4 (LFP) packs survive roughly 3,000+ charge cycles versus ~500–1,000 for older lithium-ion, run cooler and hold value better — most newer power stations use it. The trade-off is a little more weight per watt-hour.

Do solar panels work in UK weather?

Yes, at reduced output — expect roughly 10–25% of rated wattage under cloud and most of the rating in direct summer sun. Panel efficiency matters less than simply sizing up: a 200W panel on a grey day still out-charges a 100W one.
