How to Store a Portable Power Station (Including Winter Care)
A portable power station often sits unused for months between storms or camping seasons. Storing it correctly keeps the battery healthy and ensures it’s ready when you need it.
Quick answer
Store at 50–80% charge in a cool, dry place (about 50–77°F / 10–25°C), top it up every 3 months, and never charge it below freezing.
Ideal Charge Level
Lithium batteries age fastest when stored full or empty. A 50–80% charge balances battery health with readiness. If you rely on it for emergencies, many owners keep it near 80% during storm season.
Temperature
Heat is the biggest enemy of battery life. Avoid hot garages, car trunks and sheds in summer. Indoors in a closet is ideal.
Winter Care
- Don’t charge below 32°F (0°C) unless the unit has battery self-heating.
- Many LiFePO4 units can discharge in the cold (some down to -4°F), but capacity drops.
- Bring the unit indoors and let it warm up before charging.
Maintenance Checklist
- Top up to 50–80% every 3 months.
- Run a short discharge/charge cycle twice a year.
- Check for firmware updates in the app.
- Inspect cables and solar connectors.
- Keep vents free of dust.

FAQ
Should I keep my power station plugged in all the time?
Many LiFePO4 units with UPS mode are designed to stay plugged in, but check your manual. For long-term storage, 50–80% is ideal.
How long does a power station hold its charge?
Quality LiFePO4 units lose only a small amount per month, but topping up every 3 months is good practice.
