3. It's normal for the inverter to become warm to the touch while you are using it, avoid placing the inverter in direct sunlight or next to heat-sensitive materials.
4. It is important to work out the electrical demands before purchasing this inverter. Since the inverter has a fuse that trip over a certain voltage, using a small one to run equipment that requires a lot of power, will not work.
A helpful tip while deciding on the car power inverter is to add the maximum wattage that each equipment will require if all were run simultaneously. To this total, add 10%. Get an inverter that can handle this wattage and all should be fine.

I have a company phone with no car charger, & also needed a way to charge my laptop on road trips.

Haven't used it yet, but I'm sure it will work fine just like other electronics I've gotten online.

The USB port worked great for charging my phone while we were charging the laptop at the same time.

I bought this Car charger because I was going halfway across the U.S. and back, which is like a 60 hour trip. I knew I would be using my phone and laptop, so I bought this so I could charge both of them. It tends to fall out on the bumpy roads, but if you push it back in it won't fall out for about another hour.

Even with the great reviews and price I was hesitant when buying this convertor since no reviews talked much about its capacity to run a portable DVD player, but I bought it anyway hoping it would work. It did! The size is reasonable, it goes in and out of the outlet easily (a complaint on many other brands), and it works! The DVD battery got low, so we plugged it into the convertor (crossing our fingers, of course), and it worked perfectly the whole Thanksgiving trip. My kids are going to be very happy on our 25-hour car trip this Christmas. Thanks!

I already own a Tripp Lite 375w inverter, but it's bulky and noisy. So I decided to buy the Bestek 75w.

My test:

The USB and AC outlet both worked well to charge my cell phone. But when I plugged in my MacBook, it wouldn't charge. I thought something might be wrong with the Macbook cord, so I tried it on the Tripp Lite, and it didn't charge either! The Tripp Lite worked previously so I was almost sure the Macbook or its cord had the problem. When I got back home the Macbook charged fine on my home AC. So I went back to the car and plugged the Macbook into the Tripp Lite - charging light comes on! Then the Bestek - no light. Tripp Lite again - no light! I waited a few minutes and tried the Tripp Lite again - light comes on! The Bestek was doing something strange. I then use my Kill-a-Watt on the Bestek. Turns out the AC frequency fluctuates wildly - during my short measurement I saw it briefly dip to 40 Hz. This is way too low and was probably causing issues with the Macbook (Tripp Lite was more stable and my brief test didn't show it dropping below 50 Hz). Power couldn't be the issue - the Macbook adapter is rated at 60w max, so even if I add 10% as the Bestek instructions recommend, it's still below 75w. I have a 3rd gen Toyota Prius but I assume the DC ports act just like non-hybrids.

Note that other laptops probably would work, but mine didn't. Bottom line is that the low frequency is not acceptable because the standard is 50-60 Hz. I wonder if the other Bestek inverters have the same issue.

Other thoughts:

I like the compact form factor and the swiveling body; the latter helped with plugging it into confined DC ports like the one in the console box between the seats in the Prius. The AC outlet seemed a bit tight; when the Bestek was in the DC port and I wanted to remove an AC device, I was afraid my pulling would eventually damage the DC connector, or worse yet, the port. USB port was just the right tightness.

I used this converter to inflate (and deflate) one queen and two twin Aero beds for our camping trip. Just plugged the converter into my truck, plugged a 100 ft extension cord into the converter, climbed into the tent and plugged in the Aero bed electric pump and it worked perfectly. One tip, make sure your vehicle is running.

Quick shipping and reasonable price are always a plus. Works as intended to plug in the wall charger for an off brand bluetooth headset for which I could not get a car adapter. Everthings good so far!

Used this product on an American Airlines flight and it worked great. You can check on Seatguru.com to see if your particular seat has a power outlet, and if it does, you have a great solution. Your laptop adapter may not work because this can supply a maximum of 75 watts (I have an iGo adapter that delivers 130 watts. Fortunately, I have a separate adapter for it).

I purchased the PROMOTION BESTEK 75Watt 12 Volt DC to 110-120 Volt AC Power Inverter With USB Adapter MRI711C-3 on a Thursday and it arrived on Saturday. I got this product for an inflatable bed I use when camping. I have not gone camping with it yet but I did inflate and deflate the bed I use two times in a row and it worked great, just as good as the wall outlets in my home. The unit was slightly warm to the touch after about ten minutes of continuous use but not warm enough to warrant any concern. Thus far this product has done what I got it for and it has done it well.
