Note on model naming: the usable-capacity and recharge measurements below were published by OutdoorGearLab on the Anker SOLIX C1000. We treat them as the best available guide to the current Gen 2 but label them as related-model evidence; the idle-draw figure was measured on the Gen 2 specifically.
Quick verdict
A fast-charging, quiet-standby 1kWh unit whose main costs are noise under load and battery wear from habitual fast charging.
Best for grab-and-go backup and frequent recharging. Main strength: ~54-minute AC recharge measured, beating the 58-minute claim (OutdoorGearLab), with a low 13.8 W idle draw (The Solar Lab). Main weakness: one of the loudest units OutdoorGearLab tested at full load, and ultra-fast charging accelerates battery degradation. Evidence confidence: Medium. SolarGenLab Evidence Score: 8.0/10.
Buy this if / Avoid this if
- You recharge often and want speed — ~54 minutes measured, beating the 58-minute claim (OutdoorGearLab).
- You want low standby drain — a 13.8 W idle draw measured on the Gen 2 (The Solar Lab).
- You want a solid 1kWh-class unit delivering roughly 85% of its rating in usable energy.
- Noise matters — OutdoorGearLab called it one of the loudest units they tested at full load.
- You would use ultra-fast charging habitually — both Anker and OutdoorGearLab warn it accelerates battery degradation.
- You want the highest usable-capacity ratio — ~85% delivered (897 Wh of 1,056 Wh), below the class-leading 89%.
