I recently bought this unit specifically for a camping trip high in the mountains of Colorado so I could use my Air Mini portable CPAP with it. It performed as expected. I also bought the Boulder 100 Solar Briefcase to charge it up during the day. A full 8 hours of sleep only drained the battery to about 92% which would be charged to max in about 1 hour of good sun. I did purchase the 12V charger adapter for the Airmini which is more efficient than plugging in. The panels max output was 65 Watts. I might have gotten better power out of them with better positioning. I did experience issues with the battery; if I allowed the battery to get closer to 80% or lower it couldn't produce enough power for the Airmini to run. My strategy was to plug in the solar panels to charge the battery in the morning and I could charge and power all my devices all day and end with a full charge for the night. I was not powering a frig or anything like that. Just charging mobile devices and some LED lights.
Warning: those Boulder 100 solar panels are not very rugged. One of my camp mates leaned them against my truck to get them out of the way and they were knocked over. They must have landed on a rock and shattered one side. Still, they were able to product 60 watts of power for the remainder of the trip and Visa Purchase Protection did eventually pay my claim with minimal hassle.

Preliminary review
So, researched a lot of different rechargeable power packs. Goal zero is NOT the least expensive. But, it certainly seems the best. I bought the 400 li-on with the boulder 100 solar panel. Shipping and packaging EXCELLENT. Be aware that the 400 li-on needs to be signed for. It was almost fully charged when I received it today.I plugged it into the boulder 100 and came back a couple hours later and it was charged.1st test, I plugged in a 14" Patton air circulator on low in the AC inverter. I have 2 pictures of the display.I ran it for 90 minutes, it drew down the power from the 400 to 81% from 100.It was drawing roughly 6 amps on low.So, it would seem that the 400 can run this fan on low for around 7-7.5 hours which is what they claim.Seems very well built and extremely high quality.Love it so far, will continue to use and make updates as needed.Hope this helps

I plugged it into the boulder 100 and came back a couple hours later and it was charged.
1st test, I plugged in a 14" Patton air circulator on low in the AC inverter. I have 2 pictures of the display.
I ran it for 90 minutes, it drew down the power from the 400 to 81% from 100.
It was drawing roughly 6 amps on low.
So, it would seem that the 400 can run this fan on low for around 7-7.5 hours which is what they claim.
Seems very well built and extremely high quality.
Love it so far, will continue to use and make updates as needed.
