Bests & Worsts Reviews from Amazon

Mine arrived this week, got it for $100 off with the promo. Still pricey, but more tolerable at $400. I bought this almost exclusively for the purpose of having portable power for car camping at campgrounds where power isn't available. I use a CPAP (Respironics Auto 50 series, no humidifier) and while I CAN sleep without it, it's not a pleasant experience. My hope in purchasing this unit is that I can now expand the camping options available to us to include no power sites. I really love camping. My first test was simply charging it up to the full 30 hour capacity and run my CPAP for 8 hours on the AC plug. After 8 hours of running the CPAP, the PowerHouse still had 24 hours of charge left on it, so theoretically it could run my CPAP for 4 nights before requiring a recharge. I plugged it back in to recharge this morning and it was back to a full 30 hour reserve in about 90 minutes. I am impressed. I also tried hooking up a small fan (Honeywell HT-900 TurboForce equivalent) running on high. While the fan runs, It is apparent that the Anker unit is not designed to power this item to the degree that a wall outlet can, and on full power the fan ran as if on the lowest setting. Furthermore, the available power of the Anker dropped from 30 hours to 29 in a matter of minutes. EDIT 4.29 - On a whim, plugged the fan, the CPAP, and a cellphone in to verify just how long the unit would last from full charge. After the reserve dropped from 30 hours down to about 9 in about 90 minutes, it leveled off and drained at the reported rate. This combination of devices will last about 10 hours before the Anker needs recharging. My next test will be added later, with the CPAP connected to the 12v outlet using a 12v adapter (Part Number 1001956). After doing some reading, my conclusion is that the 12v option will be more efficient and therefore use a little less power. I will report on that test next week. EDIT 05.03.2016 - Using the DC power adapter for my CPAP, I ran it for 7 hours, along with a phone being charged. According to the readout on the PowerHouse, it only used one hour of charge for the entire night. This amazes me. I had no idea how much more efficient the 12v option would be, but it clearly is, and means there is practically no limit to the number of days I can take this camping with my CPAP. I envision using the PowerHouse as an intermediary power storage option if I am faced with an extended power outage. We have a propane-powered generator that I would use to charge this during the day, when the noise of a generator is more tolerable, and then use the Anker at night for running my CPAP and charging phones. As others have mentioned, this unit seems solid and well-built. Objections to it being called a "generator" notwithstanding, it "generates" power for my intentions as expected and does so in a compact, highly portable, easily (if not quickly) replenished manner. As with many "convenience" items, the price reflects the awareness of the manufacturer that yes, there are other options, but they have identified a niche and know that the people who will find this device intriguing and useful are probably going to be willing to pay a premium for that convenience. I am one of those people. I think Anker would do well to follow the suggestion of one of the commenters here, and equip future models to swap out depleted Li-ion components, perhaps in a way that made it possible to use other Anker battery products in a modular fashion, or expand the power capacity with some sort of backplane. That would be a feature that made the price absolutely and unequivocally in line with the functionality.
