Bestek 300 Pure Sine Wave Inverter: Review & Test

Bought this on an Amazon Lightening Deal for $42 USD. I was not able to load test to the rated 300 watts, but I know it can. Ideally running at 150-180 watts is a nice happy medium to keep the inverter running cool. This inverter is great to run in the car for laptops, tablets, small lights, and other small devices. For HAM radio and audio applications it is not the best inverter as it lacks any switching frequency filtering. There's is a decent amount of EMC on the AC side that is audible on my practice amp. However with proper filtering that can be eliminated. most other devices that EMC noise won't matter at all. Overall, very good deal for a small sine wave inverter!
