The verdict

The Anker SOLIX C1000 holds 32 Wh more — 3% more capacity, which on a fridge-freezer is the difference between 14 h 2 min and 14 h 29 min.

The UGREEN PowerRoam 1200 is 1.3 kg lighter, which matters if you carry it rather than wheel it.

On indicative prices the UGREEN PowerRoam 1200 is the cheaper at £649, and works out at £0.63 per watt-hour against £0.66.

Both use LFP cells, so long-term durability is a wash.

Anker SOLIX C1000 refills faster from the mains — 58 min against 1 h 30 min.

Short answer. Buy the Anker SOLIX C1000 if you want the hours and can live with 12.9 kg; buy the UGREEN PowerRoam 1200 if the price difference matters more than the extra capacity. Neither is a bad buy — they are aimed at different jobs.
