Takeaway: There are plenty of ports, 4 USB and 2 three-prong plug sockets and you can use all of them at the same time with no decrease in power.

The body of this inverter is made of a hard shell plastic and has a cool octagonal shape and contrasting black and red colors. It is fairly light, weighing 1 lb 2 oz.

I like that the fuses are replaceable. Sometimes you don't remember what the power requirements are of a device before plugging it in and it blows the fuse by accident so at least you can replace them easily without opening the unit up. To be on the safe side stick with small electronics and things without high powered motors (like a blender).

I tried this out with a 12V 35 Amp-hour battery charged using a solar panel using the clip cables. The first time I connected the battery a small spark was generated at the terminal, so make sure nothing flammable is nearby and your fuel lines in your car are secure. I also used the cigarette lighter cable and adapter with no issues. I was able to power my cell phone and chargers using both the USB ports and plug sockets. Just note that the cigarette lighter cable is not recommended if your total watt usage will be over 150.

Other users have noted that the fan that runs constantly can be loud, but I didn't find it noisy or distracting; more like a gentle hum. This inverter is great for road trips, camping, or to have in the car for emergencies when you have access to a charged battery. When using this in the car, you'll have overheating, overload and short circuit protection in both directions for both your devices and your car. It's compact, lightweight, has a decent wattage capacity and has plenty of powering options.
