SenSen AC/DC air pump - twin outlet Battery back up air pump
The advanced technology of this pump detects a power outage and will convert AUTOMATICALLY from your typical AC power supply over to its built in smart technology lithium battery DC power. During a power outage the pump will use its back up power stored in the hi grade lithium battery and will enter Emergency Mode. While the pump is in emergency mode it will continue to pulse air into the aquarium giving you up to 20 hours of oxygen supply. Once the power returns the pump will automatically return to AC power and exit emergency mode and supply full oxygen to the aquarium while recharging the lithium battery in preparation for the next power outage.
It automatically switches to battery power after disconnecting the adapter.
