Does it include a battery?

No. It is an inverter that connects to a 12V battery you supply. You need a deep-cycle battery sized to your pump's runtime needs.

Can it run two sump pumps at once?

Yes. It has two AC outlets and is rated to support two pumps simultaneously, within the 2000W output limit.

Will it work with my existing sump pump?

It outputs standard household AC through pure sine wave, so most AC sump pumps plug in directly. Check your pump's running and startup wattage stays under 2000W.

Does it charge the battery automatically?

The description covers inverting and monitoring, not charging. Plan on a separate battery charger or maintainer to keep the battery topped up.

What does the LCD display show?

Voltage, power, battery level, working temperature and alerts, so you can check status at the unit.

About 17.32 x 6.81 x 4.02 in in black, a slim shape that fits near a pump pit or on a shelf.

Our take on the KFFKFF 2000W Sump Pump Battery Backup System Inverter

The KFFKFF 2000W Sump Pump Battery Backup Inverter turns a 12V battery into household AC power for one or two sump pumps during outages. It delivers a continuous pure sine wave at 2000W with 18.2A operating current, and its LCD shows voltage, power, battery level, temperature and alerts. Two AC outlets let you run a primary and backup pump at once, and a 2.8 ft battery cable eases hookup in tight pits. It suits homeowners who already own a deep-cycle battery and want a dedicated pump backup rather than a full standby generator.
