    I want to be able to run my laptop with the charger plugged into the inverter, and the inverter to be able to do both tasks: ran and charge at the same time while in my truck.

    • A. "Depends" This inverter sounds an alarm when I plug in the 45 watt charger for my Mac Book Air. I was advised this was a 'sine' issue, a type of electrical wave, I believe. Other folks (answering here) have no problems, but do not say which type of laptop they have. A less expensive Energizer charger has no problem accomplishing this= both charging and running the Mac laptop at the same time. Otherwise, this inverter works well with multiple other devices.

    • A. If your laptop is like most I have seen when you connect it to external power you plug your laptop into a special power supply cord and the other end of the power cord plugs into a standard wall type receptacle (120Volts). The only thing that would be different is you would plug that power supply cord into a receptacle on the inverter instead of a wall plug. Most laptops will run and charge simulataneously through their special power supply cord ( normally provided with the laptop). Make sure your laptop does not require over 400 watts (most do not)

    • A. Most laptops are under 100W - e.g. I have a 17" monster and it is listed at "MAX 90W" - so unless I have audio and video and birghtest screen, etc., it's going to use less. I'd say around 75W. In any event, you're almost certainly going to be able to use the cigarette lighter to do what you want to do. (And a direct-to-battery connection will handle up to 400W - I've made pasta and rice, and it works - YUM!!!)

    • A. Most laptop power supplies run on 75 to 150 watts, so this inverter will have no issues powering a laptop power supply, allowing you to use your laptop as usual.

    • A. Typical laptop power supplies are 80-100 watts, so this will provide plenty of power to operate and charge your laptop. Depending upon your battery and the power drawn by your laptop you may have to have the engine running when connected for long periods.

One to connect directly to a 12volt battery (with alligator clamps on the end) and the other cable will plug into a cigarette lighter /accessory receptacle in a car. Please read the manual though as there are restrictions on which one you use if you are going to load the converter to it maximum 400watts

If I used this alot, I might buy a second unit - one to always keep plugged into the cigarette lighter for small appliances like laptops, and the other for heavier loads. Then you wouldn't have to keep switching the cables...

    I've had many different inverters and the Cobras just work. And work well. I really like this one as the fan is not loud nor does it run on really light loads. This unit also has a REAL on and off switch, not a soft button. (The soft button trips off and fails to start if anything is plugged in. At least in many of the soft button inverters I've used) Believe me, if you know what I'm talking about I'm sure you agree. Anyway, I'm about to order a couple more of these for the RV and the other cars in the household. Really good for Laptop power supplies and such. No matter what brand, you don't want to pull 400 watts through your cigarette type power plug but for light duty it will be fine. For heavy duty use you need a solid connection to the battery and this unit comes with both. Lighter socket plug AND the direct to battery clamps. I highly recommend this if you need a good solid performer.

    I've had this inverter for almost 2 months and it seems to work pretty good. I only used it to charge my laptop, hair trimmers, shaver and cell phone all at the same time sometimes, but so far it seems to work pretty well. I wasn't too sure about the fan coming on and off for just a few seconds at a time, but I see that's just how it is designed. The fan will stay on longer when needed. You also can't beat the price! $25! come on!! I reserve the 5th star only because you never know what mite happen later, plus I read other reviews about defective units. Four stars so far! If it lasts me a very long while, then this unit will get five stars!!

    I needed a small inverter in my RV. The Cobra 400W filled the bill nicely. I like the two types of power cards included. If you are looking for an inverter do you homework and buy the size you need. There is a lot of information on the web. Cobra has great prices and a good reputation for a company that has been around for many years. Walmart.com makes shopping easy and with free delivery to the store, it is unbeatable.

    I've only used this a few times, but so far I LOVE it. It is a SUPER value (and a shame they don't sell them in the store; the one they had was only 200W and cost TWICE as much!?). I've used it in the car to power my laptop; AND I hooked it right to the battery and MADE PASTA. I used a rice cooker since the electric teapot I had was 1000W (the rice cooker was only 300W); but it still only took 30 minutes, and didn't drain my car battery. Speaking of which... ...that's one of the great features of this unit. It has one alarm that warns you when your battery is getting too low, so you can shut it off. Then, if you don't, it has another alarm that warns when you've gone too far, and if you STILL don't turn it off, it turns ITSELF off! Last night I watched a DVD on my laptop - it lasted a little over an hour, and then the first alarm went off. Since the movie wasn't over, all I had to do was turn the engine on; and I only had to keep it on for about 10 minutes before the battery was recharged enough for me to finish my movie with the engine off! Anyway, as I said, I've only had it for a little while, but if it keeps working the way it does (and I think it will - it has a fan to help keep it from overheating, which should extend its life), this will be one of my all-time favorite devices. And one of the best values, too!!!

    I purchased this in order to run my laptop computer in the car. It is much lower cost than buying a laptop car adapter - and it is more versatile for other uses. It is nice that it comes with both a cigarette adapter and alligator clips for direct connection to a car battery. With the car adapter one shouldn't exceed around 100 watts because of the risk of blowing the car's fuse for the cigarette lighter. I find this device works - but that the cigarette plug just doesn't want to stay put properly in my car. I have no problems at all with other devices' cigarette plug - like cell phone and GPS. So the cigarette plug that comes with this device is useless - I am constantly playing with it to keep the device powered on. I'm going to need to cut the cigarette plug off, and buy another cigarette adapter (somewhere) and solder/connect the wires. It's a shame that such a good device is brought down by a badly designed cigarette plug. Howard
