Storage routines from manufacturers
- Anker SOLIX C1000 FAQ: turn off all outputs when not in use; store in a dry, cool area; check battery level weekly; if below 30%, charge to 100%; fully charge once every 3 months.
- EcoFlow DELTA Pro 3 FAQ: optimal operating 20–30°C; recommended long-term storage 20–30°C. The main unit is IP20 (battery pack IP65), so use it indoors or in a sheltered, ventilated spot.
- EcoFlow DELTA 3 Plus manual: for long-term storage, every 3 months discharge to 0% and recharge to 60%; EcoFlow says the warranty is void if the unit is not charged or discharged for more than 6 months.
- Jackery Explorer 1000 v2 manual and FAQ: Jackery's user-guides FAQ says to recharge every 3 months to keep the battery above 50% when not in use, and to store at 0–40°C and 0–60% humidity. The manual warns that storing it depleted for 3–6 months degrades performance and may leave it unable to charge, and the warranty requires a full charge at least once every 6 months.
Practical cold-weather plan
- Keep the unit indoors (above 0°C) when you need to recharge it.
- If it must sit in a cold car or garage, check the discharge minimum (−10°C / 14°F for Jackery and EcoFlow; −4°F for Anker).
- Bring it inside to warm up before charging.
