Style Name: With built in air compressor and LED lightSize: 400 Watt
Many useful features in this design: compact but capable and rugged. A recommended item for emergency power outages, and for general service where portable power is needed: starts dead car batteries, pumps tires, runs 120V tools, etc.

Two design shortcomings I hoped weren't there, keep it from 5 stars - #1: it charges from either a wall-wart 12V adapter, or from a 12V cigarette lighter plug. I much prefer a direct 120V power cord connection versus the wall adapter variety. #2 shortcoming: it doesn't have a self float-charge cycle - you must limit your charge times manually by unplugging it (battery damage if charged too long). Ach! Still, guess a person could attach his own float-charge unit instead of the supplied 12vdc adapter. But heck, Wagan, design that into it, like the better powerpacks have.

Style Name: Auto Jump Starter w/ Air CompressorSize: 400 Watt
Ironically, shortly before I purchased this item I told myself I would start leaving feedback on services and items I utilized. I figured it was only fair as I usually do tons of research on things before I spend my money and use customer reviews whenever possible. With that in mind, here is what I think of Wagan and their Power Dome EX...

We were driving cross country and were looking for an inverter/compressor/jumpstarter to carry for emergencies. Like most people we didn't need all the extra bells and whistles but they seemed like nice bonuses that were essentially free for the price. I read the reviews and, as you will see or have seen, they are are all over the place from 'love it' to 'junk.' I know even in the best product there is always a few ranting, cursing, grammar-slaughtering diatribes from someone who feels they were wronged but usually you can pick those ones out and disregard them. This item though almost seems like their quality really does run the entire spectrum. I can only speak for myself but I have to lean strongly towards 'Junk.' Like some other reviewers noted, right out of the box parts fell out and the item seemed poorly assembled. The casing did not line up and some of the trim pieces were partially falling off. Not a huge deal to me as it was going to bounce around in the back of the car or sit in the garage but not a great first impression nonetheless. Following the instructions I charged the unit for 48 hours before using which meant I couldn't test until it was about time to hit the road in two days. No issues during charging and after I removed it I did a cursory check off all the items. Everything seemed to function properly, compressor hummed, light and radio came on, inverter fan came on, etc.

I dont like writing poor reviews and this is the first one I have ever written. My wife left the key on in her 2005 Stratus all night and ran down the battery. What an opertunity to show her my new Wagan power dome
Jump start in action. Freshly charged for 34 hrs and ready to go. Wrong!
Hooked it up, Hit the starter on the Dodge and all I got was click click click click. No start. What was wrong?? I checked it again, and again. Still nothing but clicking. The Power Dome was trying really hard but no luck. I got out my jumper cables and hooked them to my old 1994 chevy pick up and the Stratus took off Zoom Zoom, Zoom. No problem. To say the least I was shocked. The only thing I could think of was the cables on the Wagan are not strong enough to carry the load, I have read in other reviews complaints about the cable connectors. Some even have replaced them because of brakage. If any one has any sugestions what to do Im all ears. Sorry my review was not a good one.

Due to the ever improving customer and tech support at Wagan, this comment is over due in coming. However, Wagan does stand behind their products, and do offer anyone that has any complaint or issue with their product to call in to 800-231-5806, or email customer service at, and we will do whatever is possible and fair to take care of you. As some reviewers have so wisely said, Power Domes,and jump boxes can not be compared to standard jumper cables, as they are not able to provide the same kind of power, and it does indeed depend on the condition/type of battery, and even sometimes the size of the engine/alternator. If you have any doubts, issues, or questions, please feel free to contact Wagan. As much as we would love a zero defect ratio, it's impossible, but at the end of the day, we strive to make our valued customers satisfied, and invite you to call into our new improved customer support team today! We are also here to help you find any adapters you may need, or cables, if yours has been replaced, or broken. Even if you have not been able to take advantage of your full one year warranty that came with the product, we still invite you to call in, and our team will do everything they can to take care of you.

Style Name: Auto Jump Starter w/ Air CompressorSize: 400 Watt
This is a fantastic unit and the price is on par with other brand units.

It has a charge indicator, FM/AM radio with aux. audio input jack as well as a USB power supply port for those suckers who own an IPOD, the LED light is bright enough, the presence of an air compressor is a plus and the hose is a decent length but doesn't appear so at first glance, 2 AC outlets as well as 1 DC outlet should provide ample space to plug in anything, and of course the jump cables for car starting which, like the air hose, is longer than it appears in the picture (about 2.5 feet)

The reason I gave it only 4 stars:
the power switch for the AC outlets on mine is a 2 stage switch, meaning it has off, 1, and 2 settings. The 1 does nothing and the 2 powers the outlets. Based upon the pictures, it is clear that a simple ON/OFF switch was meant to be there and probably is in most units but for whatever reason, mine has a different one (no biggie). The air compressor works fine but I have a problem with the fact the dial goes to 260psi. Who is pumping that much air into something? Because of that, I need to look closely when I am filling tires because the distance from 0-35/40 is very small. The tips for the air hose come loose so they will get tossed or lost easily. Lastly, the speaker for the radio is not the greatest, it would have been nice to have a built-in amp and an audio out but i guess this thing can only do so much.

Overall, it is a great buy and should do the job well for most people.
