This unit is great for ourdoor when the power supply is not accessible. I am a camper and I want all my critical devices powered when camping. This thing could do the job well. Together with a solar panel, it can generate power during the day and provide power at night. Clean and sustainable energy, awesome!
My impression of the Fremo is that it’s really good. The build quality and materials are great. I tried it out by plugging in the most power-intensive things I could think of (Kirby vacuum and Vitamix blender which I did not expect it to be able to run, but it powered both with no problem. So I’d say you did a great job on the Fremo.
I use this to power my CPAP when camping. I run my CPAP with humidifier and heated hose. During warmer weather, this will power my CPAP for two nights with a little in reserve. During colder weather it will power my CPAP for one night. I think this is due to the heated hose. I have no issues with this battery pack and recommend it.
