Convenience takes on a whole new meaning with the efficient, reliable and user-friendly Energizer Jumpstarter 400 12-volt Battery Jumpstarter. Powered by a large lead-acid battery capable of putting out 350 CA, it is designed to quickly and safely deliver automotive power on two fronts: battery jump-starting power and untethered DC current suitable for most any appliance or gadget. It also contains a rear inverter docking feature for AC power when used with the Energizer 200w inverter (sold separately). In either configuration, the Energizer 12-Volt 400 Battery Jumpstarter provides the reassurance of power you can count on while on the road.

Jumpstarting Your Car
In the event of a dead or severely drained battery the Energizer Jumpstart 400 allows you to get back on the road in minutes by simply following three color-coated steps numbered on the outside of the unit. It's as easy as 1: assuring that the unit has a sufficient charge by pressing the CHECK button; 2: attaching the color-coded positively and negatively charged 24" power output jumper cables, via their heavy-duty 400A metal battery clamps, to the appropriate positively charged post on your car's dead battery and a ground position on your engine block; 3: turning the power switch located in the clearly marked JUMP section of the controls from OFF to JUMP, and starting the car with the dead battery. When your vehicle starts and has run at an idle for a few minutes remove the Jumpstart 400's cables in the reverse order they were connected, turn off the unit and you are ready to roll.
Standard DC Power and Optional AC As Well
Along with its automotive exclusive functionality, the Energizer Jumpstart 400 provides the power and access to power that users of modern devices need on the road. The unit comes standard with one rear-oriented 12-volt DC socket suitable for powering 12V devices utilizing a cigarette lighter adapter. Devices plugged into this are protected by a 30-amp manual-reset circuit breaker located at the back, that ensures that they are never exposed to more power than they can safely handle. In addition, the unit's rear inverter dock functionality means that user's also have the option of access to three-pronged AC power by way of Energizer's 200w Inverter, sold separately.

Easy to Maintain Power Levels
Because even the best jumpstarter unit is of little use unless it contains sufficient power, the Energizer Jumpstart 400 is designed to be easy to charge and effortless to maintain. Unlike other manufacturer's units that can be damaged by overcharging, the Energizer Jumpstart 400 contains a two-stage internal charger that allows your battery's power to fluctuate within a very small range while attached to AC current for charging. At the highest level of this range through the middle, charging ceases, while when the lowest is reached charging begins again, continuing until the highest level is reached. This creates a charging cycle, yet cuts the battery off from the damaging effects of excess power. This means that the unit can safely be connected to a wall outlet indefinitely, ensuring that the unit will be ready to pop into your trunk at full power whenever you want it.
