Review: BESTEK 300W Power Inverter DC 12V to 110V AC

AC power outlets can be added with a power inverter and can give power to small devices such as laptops.

The BESTEK 300W Power Inverter is one such unit that converts 12-Volts DC to 110 Volts AC.

A vehicle’s cigarette lighter is used to convert the power.

Keep in mind every vehicle cigarette lighter will have a different Amp capacity and should not be overloaded.

Most vehicle cigarette lighter Amps range from 50-200 and depend on the make model and year.

For example, to test the BESTEK 300W I used a 2012 Toyota Corolla cigarette lighter which has a rated 120 Watt max load.

How many Watts a device pulls will be labeled on the unit somewhere.

For example, here a Toshiba laptop was used for testing which uses 19 Volts DC and 2.37 Amps.

To get the Watts the two are multiplied together 19 X 2.37 = 45.03.

So basically the laptop will only pull 45 Watts which wont go over the cars rated Watt draw.

If a cigarette lighter does blow a fuse they are usually easy to replace at the fuse box.

An alternative to the cigarette lighter is an adapter that goes straight to the battery with cables.

Summary
he BESTEK 300W Power Inverter is a good unit to convert DC voltage to AC voltage and small power devices.

It worked very well, powering my laptop, and I plan to do more testing with other devices.

The unit also has 2 USB ports which are nice to have when multiple devices need power.

Be sure to check your vehicle’s cigarette lighter rated Watts so as to not pull too many amps.

I am still testing the unit so far with good results and will update if anything changes.
