Convenience takes on a whole new meaning with the efficient, reliable and user-friendly Energizer 84020 All-In-One 12V 18Ah Battery Jumpstarter with Air Compressor and Power Inverter. Powered by an internal 12-volt, 18Ah sealed lead-acid battery capable of delivering 350 CA, it is designed to quickly and safely deliver automotive power on three fronts: battery jump-starting power, air compression for tire inflation and untethered AC and DC current suitable for most any appliance or gadget. Covering virtually any temporary power requirement, the Energizer All-In-One provides all the power needed for any getaway.

An easy-to-use, safe, portable power for jumpstarts, air compression and AC/DC power. View larger.

Jumpstarting Your Car

In the event of a dead or severely drained battery the Energizer All-In-One Jumpstarter 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, spark-resitant 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 All-In-One Jumpstarter cables in the reverse order they were connected, turn off the unit and you are ready to roll.

Air Compressor

The only physical connection any car has with the road is through its tires. Because of this correct tire pressure can affect everything from improved gas mileage, to correct handling on the road and the avoidance of unnecessary exposure of tires to the possibility of puncture or blowouts due to underinflation. The air compressor built into the Energizer All-In-One Jumpstarter easily addresses these issues by funneling its portable power into the ability to fill tires whenever the need or want arises. When sufficiently charged, the unit is capable of inflating most any automobile tire within 10 minutes, and is easy and safe to use with its ON/OFF switch and built-in pressure gauge located on the front of the unit. The compressor also is thermally protected from overheating, and has a strong, fabric-covered output hose with a screw-on valve stem coupler.

Rugged construction, convenient cable storage and manual circuit breaker protection. View larger.

DC/AC Power and Light When and Where You Need It

Along with its automotive exclusive functionality, the Energizer All-In-One Jumpstarter provides all the power and access to power that you will ever need. The unit comes standard with two 12-volt DC cigarette sockets for powering 12V accessories. Both are protected by a 30-amp manual-reset circuit breaker, located at the back ensuring that your devices are never exposed to more power than they can safely handle. In addition, users also have convenient access to three-pronged AC power by way of the built-in 200 watt, DC/AC power inverter. This component also contains a built-in cooling fan to prevent any overheating during this power conversion and an ON/OFF AC power switch to minimize the possibility of power drain when cords are left plugged in. The All-In-One Jumpstarter also contains a flex-neck work light stored in the unit's handle that allows the user to shine a little light virtually any place.

Easy to Maintain Power Levels

Because even the best jumpstarter unit is of little use unless it contains sufficient power, the Energizer Jumpstart All-In-One 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 All-In-One contains a 12V, 1 amp internal two-stage 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.

4.0 out of 5 stars Almost perfect..., September 24, 2010

This review is from: Energizer 84020 12V All-In-One Jump-Start System with Built-In Air Compressor and Power Inverter (Automotive)

A great ergonomically designed little jump start unit.
I love the fact that it can be left plugged in perpetually
and will take care of itself. I'm not mechanically inclined
so the less I need to do the better.

The only complaint I have about it is that it doesn't come
with a cord to plug into the wall. You have to get a heavy
duty extension cord to connect it to the wall, and they
never tell you that when you are reading the product
description. For the price of this item, I think it should
come with a simple short extension cord.

5.0 out of 5 stars Not Dead in the Water!, July 27, 2010

By 

Adrockdallas - See all my reviews

This review is from: Energizer 84020 12V All-In-One Jump-Start System with Built-In Air Compressor and Power Inverter (Automotive)

If it weren't for my All in One, I would have been dead in the water, literally, on Lake Lewisville in Texas. Needless to say, we ran the stereo & fish finder WAY longer than we should have and found ourselves stuck in a cove in the middle of nowhere. We brought the all in one, with the intention of just using it to inflate to tubes for the kids, but the Jump Start feature is what really saved us. I didn't even realize that it had a light on the handle (thank you wife for noticing) but that came in handy too trying to jumpstart a boat in the dusk while mosquitoes were starting to attack! I have since recommended it to many of my co-workers and fishing buddies.

2.0 out of 5 stars Very handy product - but not much real customer support., December 15, 2010

This review is from: Energizer 84020 12V All-In-One Jump-Start System with Built-In Air Compressor and Power Inverter (Automotive)

This jump-starter, air compressor, inverter, is of excellent quality and usefulness. As mentioned in other reviews, it would be nice if they included an AC power cord; and possibly a DC power/charging cord for the price. This is a fairly large unit and takes up a large amount of room in a trunk or the back of a station wagon/hatchback. It charges fast and has plenty of reserve power to start our motor home or inflate large tires. Great carry handle.

UPDATE 19 May 2011: The user manual was missing. Now I need it to check something. Item itself is pretty user friendly. Tried to download manual on website from manufacturer (UPGI.com) but no manuals or documents available from support. None available from Energizer. Tried Google. No one has uploaded manual yet. Finally found support 800 number for UPG Inc. which is also a wholesale/retail sales number. Nice lady answered. She took my name, email, telephone, address, etc. Said she would "look around" for one and send it "somehow" if she finds one.

Apparently, this is a "marketing arrangement" where they buy the use of the Energizer name, then import and distribute it.

Design pretty good. Sales-marketing good. Support not so good. Technical support essentially non-existant. Downgraded to two stars. Will post another update if I ever get the manual.
