An essential part of my RV lifestyle while traveling or parked. I need a couple extra sockets for charging cell phones while driving our motorhome as all the charging ports are being used for other devices. It's also great around the garage for exercising my lithium RV batteries during storage in winter months. The Bestrk 500 watt 12 v inverter works great. I'm very pleased with the results of my purchase. Highly recommend.

Powering a Nebulizer

The BESTEK worked without flaws. I purchased the machine to provide the power to administer a Nebulizer to the person in the back seat of my vehicle during long trips. The BESTEK had the power necessary to to do the job without having to any power interruptions or uneven power. The BESTEK is easy to set up and operate.

Bought this inverter to go camping, making coffee on the go and frying eggs. It's saving me money, beats spending at gas stations
