How Do I Care For My Powerstation External Battery?
Keep your powerstation battery dry and away from moisture and corrosive materials.
Do not clean your powerstation battery with harsh chemicals. Just wipe the exterior with a soft, water-dampened cloth, or dedicated electronic cleaning wipes with less than 75% isopropyl alcohol.
Make sure the powerstation battery’s USB ports do not become contaminated with lint or other debris. Use a canned-air type of product periodically to ensure that the port openings are clear.
Recharge your powerstation battery once every three months when not in use. If you plan on putting it away, fully charge it first (so that pressing the status button lights all 4 charge status LEDs)
