If you’re often on the road and find your vehicle’s charging or power ports lacking, or feel limited by the car adapter options available for your mobile devices, then the BESTEK 300W Power Inverter (12V DC to 100V AC) may be right up your alley. This useful device plugs into your vehicle’s standard DC power port (aka, the “cigarette lighter”) and converts its output to two standard AC outlets, as well as two USB charging ports.

In the box, you get the power inverter itself with attached 24″ power cable and an instruction manual. As you can see from the photos, the BESTEK is nicely designed and surprisingly compact. Overall build quality is good.

The two AC outlets are rated for 300W, with a maximum output of 350W max and a 700W peak. As expected, if for some reason you overload this device, its 40 amp fuse should have you covered. In terms of the two USB ports, they’re both 2.4A, with the top port auto-sensing.

When the BESTEK is powered on, a fan, which is definitely audible, constantly runs to keep the unit cool. Fortunately, along with all of the other safety protections in place, like the overload protection, there’s also overheating protection. Even when the power inverter portion is switched off (which you should do when the AC outlets are not in use), the USB ports still work, so it’s a device you can leave plugged in full-time if you wish.

This is definitely a useful device. It’s great for when you need to use your laptop (and of course, even larger, non-battery powered devices) and its battery is drained, or for long car rides when USB charging alone just won’t cut it.

Thanks to BESTEK for the review unit.
