This inverter is compact and does exactly what it is intended to do. The USB slot is a nice feature. I have used it on 8+ hour roadtrips powering cell phones, laptops, DVD players and other items. Never a problem. Wagan EL2402 SmartAC 200W Power Inverter with USB Port
Very nice, I use it in my SUV, then hook my notebook up to it, runs a little hot but not too bad, I also charge my cell phone off it, small, and has an on/off switch with a green power light, I like it.
I don't really see how you could get a better product. I took it cross country MA to CA and back, it worked like a charm always for all my charging needs. The USB is really handy for cell phones leaving two ports open for larger plugs like laptops or cameras.
I have an Odyssey deep cycle battery in my car. I ran my power hungry Dell desktop replacement laptop off this charger for 2 weeks, no problems. The laptop has a 90W power brick. I also ran the 90W laptop power brick + a 50W external laptop battery charger at the same time. If your car's wiring is protected by a 20A fuse, then 200W continuous is the most you're going to safely pull through your cigar lighter. I picked this unit because it's 200W continuous. Many of the other available "200W" products are just full of marketing slime and don't give 200W continuous, they give 200W peak power for a few minutes and can only handle ~150W continuous. Small annoyances: the user manual claims it has an airplane plug adapter but it doesn't, and the plug is so long that it's not the best fit for my car's cigar lighter. I have to carefully align the flexible springs on the plug to get it to stay in, but if so aligned they do stay in.
We went through two of the Wagan EL2402s. The first arrived and a piece of solder fell out of one of the vents. May have been extraneous, but better to be safe than sorry, Amazon was great and overnighted a replacement. At best I can only give mixed reviews. The is supposed to be able to handle 200 Watts with a peak of 500 Watts.. Fairly substantial in print. In reality, things like battery chargers, cell phone chargers, etc., all seemed to be fine. Where the problems began were on more "specific" devices. We wanted the device for my wife to run a 35 Watt Chi hair straightener. It would not even turn on. The description says power tools, so I thought I'd given a try to a couple. First a sabre saw, again well under peak and normal wattage to be handled. Nothing, a blip when I pulled the trigger, then nothing. A Dewalt hand drill... well kinda sorta.. If you started out VERY slowly on revolutions and worked your way up, you could get to full speed. I didn't try that under a load, but I assume it would work to a point.
I called Wagan, and they assumed some of the failures cames from the fact that AC devices are used to and built for a sine wave output. The Wagan (and I assume some others) don't produce the exact same sine wave (calling it a modified sine wave). So, your own mileage may vary. Some Notebook AC Chargers may be more sensitive than others, so you probably can't be sure. Again, I don't know that Wattage alone is the delimiting factor. It may that your particular device just won't work.
My advice, read the reviews.. If you have a particular device or devices you are thinking about running, perhaps check with the manufacturers of these different inverters. Remember electronics are pretty sensitive devices when it comes to power. While I may be willing to try a Chi hair straightener, I may not be as comfortable with a notebook.. Best bet there is to see if your manufacturer has a DC supply (Car/Airplane) adapter.
I use this primarily on airplane flights. The device is nicely sized, and it fits in my travel bag well. It worked like a charm when I had just my laptop plugged in, but when I plugged my phone into the USB plug as well, it seemed to stop charging both items. The device was also pretty hot after use, but all-in-all, it does the job for my needs.
A little early for an in-depth review as we just recently purchased the inverter. At this point I can say that it has performed well. We have used it to charge cell phones as well as batteries for our camera and it functioned exactly as advertised. It is fan cooled and the fan operated well and there was no problem with noise. It was warm to the touch, but I believe it is normal for them to generate heat. The only way to make it run cooler would be to increase the fan size which in turn would increase the case size and make it less portable. Based on our initial experience, I would recommend it as an excellent purchase.
Worked really well for our recent travel. I was able to connect my GPS and a portable DVD player without any problem. I didn't get a chance to charge any USB devices because I had a wall-charger for them and it was just easier to plug it in then trying to fiddle with the USB port while driving. - Power Inverters - Inverter - Car Adapter - Portable'
