Power outages? No problem! This air pump has a built-in transformer and rechargeable battery. When plugged into 115VAC, the air pump operates continuously, while keeping the battery charged. When the AC power shuts off (or is removed intentionally), it automatically switches to its internal battery and keeps running. It will also double as a DC air pump for an unlimited length of time when using an external 12V power source. Sorry, the internal rechargeable battery is not replaceable.

Includes:

• 115V cord
• 12V cigarette lighter cord
• Two 3/16" outlets
• Alligator clips
