Keep your powerstation AC battery dry and away from moisture and corrosive materials.
Do not clean your powerstation AC battery with harsh chemicals, soaps or detergents. Just wipe the case with a soft, water-dampened cloth.
Make sure the powerstation AC 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 AC battery once every three months when not in use. If you plan on putting it away, fully charge it first (so that pressing the charge status button lights all 4 status LEDs).
