Customer Reviews

Not perfect, but does a good job.4
I recently used this product on a 3000 mile/5 week trip in which my wife needed some extra power ports. The product does a very good job sending power to it 4 plugs (two DC and two USB).

The biggest draw back is that the product would sometimes work itself out of the socket and thus stop sending power to anything. My van has two DC plugs in the front. One is the normal depth of a cigarette lighter and the other was a littler deeper. We never kept it in the regular cigarette lighter because it would come out too easily but it would still occasionally work itself out of the other deeper socket we have as well. On our entire trip I think this may have happened 5 times.

I would recommend this product though it is not perfect.

Works great, good value5
I bought this a few months ago, mostly to charge my Sony Walkman MP3 player. It looks very well build, and I've never had it work it's way out of the 12 volt socket.

The time to charge my MP3 player using the USB port is much less than that required when the player is plugged into my computer.

I'd definitely recommend it.

Works great4
Like the other reviewer said, it wiggles far enough out from time to time that the power goes off, but it's rare enough that it doesn't really bother me. I have found it very useful to have the extra plugs and am definatly glad I got it. the way that it folds down is helpful, I have it folded so that it is flat against the car and out of the way of the shifter, although it would probably fit if it stuck straight out.

Customer Reviews

Works great - while it still works!3
I have had this seat cushion for about a month and it really does the job well in Tucson. No matter how hot the car is when you get in it you feel cool in a few seconds. I was surprised to find that the air flow is as good up your back as it is in the lower part of the cushion. Another pleasant surprise was the included AC adapter for office use. The ad indicated that was optional.

I would have given it a 5 star rating except for the poor construction. Initially it looks well made but the quality of construction is just not there. I had to rebuild the speed control because it was flaky and was only giving one speed. Yes, I could have returned it but did not need the hassle and I knew it was an easy fix. The fan motor itself is housed in a zipper pouch on the front of the cushion and hangs down in front of the seat when in use.
After a week of use it did not seem to cool as well so I checked the motor and found that the zipper opens up on its own and lets the air out so it is no longer blowing into the cushion. A zipper with a lock could have cured this. I also found that the power cord, which is secured to the top edge of the fan housing with two small cable ties, had come loose and the wires were at risk of breaking. They just never made the cable ties tight at the factory. This was an easy fix as well.
After 3 weeks I again noticed that the air flow was not as good as it should be so I checked the zipper. This time the entire back edge of the pouch was coming un-stitched from the cushion. I could tell there would be no point in returning the unit for a new one because it would just do the same thing so I repaired the seam with contact cement.

It's a shame! This could be a really nice seat cover because it works so well when it does work, and the fixes would be so easy for Wagan to make.
1. Do a better job with the motor control. (Quality control)
2. Put a lock on the zipper.
3. Double-stitch the motor pouch seams.

I got this unit on sale for about 30 bucks, but would pay twice that if they built it better.

worked great until it stopped working!2
I used this seat cushion for a couple months last summer (I live in Arizona, today it was 111F). When it got cooler, I took it out and put in my seat warmer for the winter. I just put this one back in about a month ago and it just stopped working two days ago. End of story. But, as hot as it gets here, I'm tempted to buy a new one when available because it does make a heck of a difference because of the evaporative cooling with the "dry heat" here in AZ.

Nice and cool5
I have psoriasis on the back of my legs which is made worse by sweating in the summer. This seat works great to keep my legs cool and dry on long rides and I just ordered a second one for another vehicle. I like the product very much.

Customer Reviews

Reliable, fair size and well designed inveter5
I had before two other brand name inverters, but I had troubles with them, as they kept tripping the protection, got too hot, and overall I could not run a lap-top and my son's game console in the same time.
On the other hand, the Wagan inverter (400W continuous / 1000W instantaneous) ran excellent in several long trips. No problems whatsoever, I powered all kind of equipment, from lap-top computer, to cell phones charger, GPS power supply, my son's Game Boy system and Game Cube. Most of the time it ran just warm, but a few times it did get pretty hot, however I had no problems with it at all. The best features are that it has two power outlets so you can plug in two "things" in the same time, and has also overload and overheating protection.
It was certainly worth the money.

Customer Reviews

very good4
So far I found this inverter to go just what it says it will do and that is to power up your electronics on the go. I recently bought it for my trip to Florida-Orlando. We were flying so I wanted to use my new laptop and needed something to keep it powered up on the plane. Unfortunately for me I did not check out the web site for tips on how to use it. I did not understand how I was going to do this since there was no adapter for the laptop, (there is an adapter for the Airplane, I just did not know how to attah my laptop to the inverter) but I did hook up my ipod. But when i got home I looked at the website and saw that the two holes on the inverter is where the normal plug(A/C) goes. So I now know. That was my fault. It also comes with an adapter for the car so on my next trip I will get to use it properly. It can be a big help with all the electronic junk needed to entertain the kids. I recommend this highly to all travelers with kids or who are kids at heart.

Great for the constant traveler4
This product can be used in airplanes or cars. Airplane use is limited unless you fly in business or first class frequently, but I have used it when I find an outlet. Newer airplanes are beginning to have regular 110 outlets at the seats so this won't be necessary some day. My most frequent use is in the car for charging various electronics or using my computer in the car. It makes a bit of noise and gets hot when in operation, but it works great. It's small and easy to pack in your carry-on. The USB connection is handy, too. I can charge my phone and my computer at the same time.

Portable Automotive Compressors5
As a proffesional mechanical and industrial field engineer, I give high marks to this unit. It's compactness and performance are well appreciated. It performs quietly and efficiently. I have owned several portable automotive compressors over the years and this unit easily out-performs them all.

It would, however, greatly benefit by being suppied with a storage case of some kind!

Excellent compressor5
I wanted to replace my noisy, slow, plastic automotive compressor with something more durable. I've been very pleased with my purchase of the Wagan unit.

The metal construction is solid, and compliments excellent performance. I topped off four car tires in the time it would have taken my old unit to do one. I even refilled a flat spare to 60psi in minutes, a job that would have overheated and probably killed the old compressor. The Wagan hardly broke a sweat.

The Wagan is significantly quieter, faster, and appears to be much more solid and durable than the typical plastic automotive compressor available out there.

Heavy duty splitter5
This splitter is HEAVY and bulky. But if located correctly, these are advantages. I was using all 4 outlets with multiple swaps going on all day by people from different angles in the van, and there was never a problem with intermitant contact or loose contacts. I attribute that to the heavy casing and the heavy outlets. The only caution are the two tabs used to attach the splitter. They appear to be undersized if the splitter is hung. I used both the provided double-sided tape and the tabs to hang my splitter - it is quite stable.

Nice lil' box4
Not much to it. But still, it does what it supposed to do, and and is solid.

Comes with screws and a mount for the dash, and double sided tape so you can mount the way you prefer. 4 outlets, one with the "spring" bit that works with your cig lighter. The maybe 3' cord leading to the device is nice, and makes it flexible for mounting.

Works like a charm5
I bought this inverter because I have a satellite radio and a cell phone. It has four outlets, and I wanted to have a couple more available if I ever need them. It fits into a little bay on my dash, isn't too bulky, and I've had no problems with it at all. Highly recommended.

Customer Reviews

Solar Power for your Laptop!5
I live on the Gulf Coast and was just hit hard by Hurricane Ike. I bought this solar product to help power my laptop and it works very well. You will need sunshine and a 12 volt inverter. At this time I have not fully played with the device, but when I plugged my 12 volt inverter, it came alive with full power.

Excellent power source for remote living5
I bought this panel for my friend who is a missionary in Haiti. She is often without any electricity, and would find herseld with no way to communicate to the outside world. When Haiti was hit hard by 4 hurricanes - all power was lost for weeks and weeks. This panel has allowed her use her computer and to charge her cell phone. She is no longer cut off, and can also get her work done. It has been such a hit there, others in Haiti are asking me to bring them one!

Pros and Cons4
To be objective..

Pros:
- Well built (although has those sharp edges as mentioned in another review)
- At 9AM, clear sky, mid May in Brazil, around 17 degrees Celsius (it is Autumn and the temp is dropping), it is generating about 8 watts (18.8 volts at 0.44 Amps.. probably around noon is going to be even more powerful)

Cons:
- 18.8 volts! Depending on the device you are connecting to it, it may be burned if not tolerant to higher voltage. It should be around 12v, and I think 50% it too much variation.
- The picture shows a girl with the panel hung to a backback. Indeed, you will need to make holes in the fabric in order to do that.. there is no way to hang it as it comes from factory
- Those sharp edges and the pet finish over the panels can be improved. Something that would be more scratch-resistance would be best, especially if you are taking it outdoors.

I surely recommend the item, but I'll definitivelly look for a small solar charge control to use with the panel. I'm no electric engineer and I've read you dont need one for panels that dont go beyond 12w, but 18v is too high IMHO, so I'm kinda scared of connecting my Garmin GPS to it. I'll probably look for "Sunforce 7 Amp Charge Controller".. never tested or seen it, but the reviews shows that it may worth the try.

Edit:

With direct sunlight, from 9AM to 11AM, it fully charged two CR123 Tenergy batteries in about 2 hours, what is really amazing. On the other hand..

Now I'm measuring the power generated by the panel with the sky covered by clouds. It is noon, pretty clear on the same day, but no direct sunlight. It is quite a surprise it is still generating those 18 volts, but now, at 0.04 amps ONLY. Since the Tenergy batteries are charged already, I cant measure how long it would take to charge them, but I believe it would take quite long... I'll update this later whenever I can test charging them again w/o direct light.

Customer Reviews

Very interesting and quite useful product4
I got this for my husband, who dislikes cold winter days. Overall the heated seat is a good value for the money. The cable with cigarette lighter plug is quite long and will probably even make it to the back seats, if anyone wants the cushion there. The unit just plugs in and in about 2 minutes you have heat. There is no adjustment of heat, it just warms up gradually then stays there. On the plug there is a red light to show you it's working. There is no need to disconnect when turning off the car since the power is cut to the cigarette lighter. The only gripe I have is the way this seat is attached. There are rubber bands with plastic hooks at the top of the seat for hookup(can run around the headrest), then there are rubber bands on the sides(these can be run behind the seat, a bit short) and finally there is a rubber fitting underneath the seat, presumably to go over the seat. Seems in most cars this is useless, as most car seats are sitting on rails to move them back and forth and there is not enough clearance to use the rubber bands for secure fit. The only way to install is just to place the cushion on a seat, then hook up the upper bands and hooks, and then the same thing on the side. The seat cushion will move around somewhat, but it's not too bad. 4 stars because of the problem with attachment to seat. This product does not allow you to adjust the heat, so for heat sensitive, get a product with adjustment, although probably have to spend at least double. Also the cord comes out on the driver side door, so it has to go under the seat cushion to reach the cig. ligher. OK if on passenger side. Good, working product overall, does what it says. I would buy this product again.

Worked like a charm.5
It was used for a road trip right after we received it. My 82 year old Mom has terrible arthritis so usually a car trip is out of the question. The seat warmer made it much easier for her. We also bought one for Dad. He didn't turn on the heater, but commented on how warm and comfortable it was even without heat.

Exceeded my expectations5
I shopped long and hard for a product like this! I almost bought my new car based on whether it had heated seats - the problem is, I wanted the Honda Element, which doesn't offer that feature - and most cars that offer heated seats are leather, which doesn't hold up well with my traveling dog. I found this product on Amazon, liked the price, and ultimately trusted the review of the consumer. The best feature about it is that it heats up instantly. I really don't know what the difference between the standard and the delux model is, but for a couple extra dollars, I thought it was worth it to try. Durable, light and easily cleanable. I've been telling everyone I know about this wonderful product.

Nice and portable, wish it held a charge for a little while4
I use this in the winter to keep snack warm for ski racers out on the hill. If only the battery held a charge for a little while, it would be perfect. Still, it is the best thing I have found available - very lightweight. I warm "hot pockets" in my oven at home, then I wrap them in a couple sheets of paper towel and then foil. I pop them into the pre-warmed cooler and plug it into my car lighter and drive to the hill. They stay nice and warm for over an hour, even in really cold conditions.

Wagan 2045 SelfCharge Auto Jumper In-Car Jumpstarter

Product Description

No need for jumper cables. The Wagan SelfCharge Auto Jumper allows your to jump start your vehicle from inside the safety and warmth of your car. The powerful sealed alkaline battery has 5 Amps and 14.5 Volts of power. Simply plug the jumper into your cigarette lighter and in 10 minutes you are ready to go. The jumper is unaffected by extreme weather conditions. It recharges from your car battery through the cigarette lighter while driving for 30 minutes to 120 minutes.


Customer Reviews

Not a substitute for a Jump Start3
From the Magellan's catalog description:
"PLEASE NOTE THAT THE LABEL ON THE AUTO JUMPER STATES THAT IT WILL RECHARGE A *DEAD* BATTERY IN 10 MINUTES. THIS IS ONLY TRUE FOR SMALL ITEMS SUCH AS A CELL PHONE OR A LAPTOP BATTERY. THE AUTO JUMPER IS DESIGNED TO RECHARGE A WEAK CAR BATTERY, BUT WILL NOT RECHARGE A COMPLETELY DEAD ONE. "

So if you've left your lights on for three hours (like many people do), don't expect this little gizmo to get you going. However, it IS a handy, sealed, self-contained source of 12 volts for many purposes, with a built-in recharging system.
