Monessen Exacta 32 Inch Vent Free Circulating Clean Face Firebox Attached

I'm Satisfied

Two weeks after receiving the AC300 and B300, we had a 7-hour power outage due to a heavy thunderstorms. The Bluetti powered our home fridge, TV, and computer without any issues. We are very thankful to have them.

Great Value for Money

The stove is working beautifully! Up here in the San Juan Mountains, we're starting to experience some chilly mornings. Today, it was below 30 degrees at 7 am! I'm grateful for having this Heater, especially since the days warm up to nearly 80 degrees, making it pretty spectacular.

Impressive Selection

I've been using my Bluetti generator for three days now and it's still going strong at 60% availability. I absolutely love it!
