The heart of the Duracell Powerpack 600 is a sealed, non-spillable 28 amp-hour AGM battery.
It can be safely and conveniently recharged from any household AC outlet or DC cigarette-lighter outlet,
making it ready to go whenever you need it. This robust battery is tied to a power inverter that provides
600 watts of power to its three grounded AC outlets and one DC socket. Multiple outlets give you the flexibility
and convenience to operate several appliances at once, while the 3-digit barragraph LED indicator
dynamically monitors the Duracell Powerpack's battery charge level. Internal circuitry ensures long
inverter life by protecting against overload and over-temperature conditions. An audible alarm also
signals during overheating and under-voltage situations, alerting you to any possible safety concerns.
