Very happy!
I got this to use for winter camping in a small teardrop trailer. It’s primarily being used to power Ignik a double Flipside Heated Bed Cover - basically two of their bed covers snapped together to cover a queen mattress. This unit performed wonderfully on its first outing of 4 nights in 20° to 30° Fahrenheit weather in the eastern Sierras. Running both covers at 40 to 100% for up to 10 hours depleted the battery approximately 50% per night. I was able to recharge it while driving around and exploring or via 100 watt solar panels or via the 12 volt outlets in my trailer during daylight hours without issue for use every night and never ran out of power. I could have relied on the power in my trailer but didn’t want to chance running the trailer’s battery down and having issues with the refrigerator so this seemed the safest route. After this trip as a “trial” run I honestly couldn’t be happier with my decision to purchase this out of all the options out there. The River is very versatile and easy use and manage with app and on board controls, and seems capable of handling numerous use cases. My one complaint is not being able to shut absolutely all the lights off while it’s operating - I like it dark when I sleep. I simply hung a towel over the shelf where it sat in my trailer to solve this very minor issue. I’d buy this again in a heartbeat.
