🔌 Premium Quality BESTEK 300W Pure Sine Wave Power Inverter Car Adapter DC 12V to AC 110V with 4 Review

So far so good, a 150W halogen lamp ran for a few hours to test the inverter. Passed with honors. The inverter showed no signs of heating at all. The power cord also stayed cold. The fan ran slowly and quietly.

Bought this for my wife's car as I have one for our other cars. These devices are convenient and power devices that require AC power through a standard AC plug. This one is really well designed and attractive - very elegant and quiet. We mainly use it for my grandkids' devices, which don't have USB sockets, just AC power adapters. Because of this, I had to add a three-socket adapter to accommodate the size of the power supplies - the sockets on the unit are too close. I bought this inverter…

March 31, 2019 This Bestek 300w inverter is more than twice the size of my 150w inverter that I am currently using. The size may not be suitable for people who have small sedans or

Most inverters output a "modified sine wave", which is essentially a stepwise square wave approximation of a sine wave. This is quite satisfactory for many purposes such as lighting, electronics with switching power supplies (laptops, phone chargers, etc.) but can cause problems for devices that are very sensitive to the quality of the power received, such as motors, some medical devices. Appliances, etc. Such appliances require a "pure sine wave" inverter that provides a smoothly varying sine…
