Storing the Powercore 20000

My Powercore 20000 is at around 50% charged. I won’t be using it until my next hike. Should I store the Powercore in the refrigerator and then fully charged it the day before my next hike? I love my Powercore and want to take the best care of it. Thanks in advance.

I don’t think you need to put it in the refrigerator as long as your house is 65-75 degrees Fahrenheit. Definitely don’t charge it until the day before you use it.

You may store it in some dark cool place at your home, may be a closet - just to avoid extreme temperatures.

Not sure of your hike schedules, so it is best practice to discharge and recharge it at least once every 4 months to extend the life span of the powerbank, since keeping them without discharge / recharge for extended time periods will make these less active .


Do NOT put in the refrigerator! Never but modern batteries or electronics in there. Between the cold and condensation you’ll damage them.

To store anything with lithium batteries long term (6+ months) get it to ~50% charge. Then place it in a cool, dry environment. Assuming a climate controlled home then a closet or drawer should be fine.

If your hikes are less than 6 months apart then there isn’t much benefit to storing it. If we’re talking weeks you may be better off keeping it plugged in.

There are several things you can do to maximize your power bank’s life. But doing them all makes you slave to the device. Can you afford a new power bank every 2-3 years? If so then just do the basics and don’t worry about it.


Yeah I would agree that the fridge would risk condensation. My understanding was that they should be charged around 75% and charged every few months. Other than that keep it at a mild temperature.
