I purchased this item to use mostly for my C-Pac when I go camping or for use during a power outage. I do not use the heater on my C-Pac machine. First night the Anker Powerhouse 535 has 73% capacity left, second night was down to 43%, third night was down to 18%. I charged the Powerhouse 535 back to 100% in less than 4 hours. I am totally impressed with the Anker Powerhouse 535. I love how simple the design is and the portability of the Powerhouse 535.

Bought this to use as power for CPAP machine while boondocking. Very pleased as it only used <25% battery per night, Airsense 11 with humidity and heated tubing turned off. I ran it for 3 nights and still had 30% charge left. Used the supplied 12V charger to bring it back to 100% in about 3.5 hours of driving.

Bought this specifically for use for my Resmed Airsense 11 CPAP machine (24V) for boondock or dry camping (camping without electric hookups). With the use of a DC power adapter for my unit, the PowerHouse 535 had 59% left after one night of use for 7h37min with humidifier settings on. With the humidifier settings off, the power station had 91% left after 7h28min of CPAP use. So without the use of the humidifier setting on a CPAP, this would be plenty for a week of camping. Great product.

Bought the 535 to power my Phillips Dream Station CPAP while tent camping. Started at 100% charge, ran the CPAP for 8 hrs without humidifier and woke up at 64%. Extremely happy with my purchase. Will be buying a larger generator for the house now that I have confidence in Anker products!

This power bank is awesome! Very intuitive design with an excellent screen read out on the front of the device. This power bank has plenty of power for my off-grid cabin visits. Pair this device with the 100W solar array and you can recharge in about 4 hours. Free renewable energy!

Great purchase! I got this 535 Power station to operate all my electronics on vacation and for general use around the house. I was worried at first that this would not operate a small coffee machine but to my surprise it does! The power station is a 500watt unit and my coffee machine ended up being 400watts(only a 6 cup percolator). This is all I need! I was able to charge all my devices, run a coffee machine(seperate due to wattage), and the station still has plenty of battery left. I highly recommend! I'm actually stoked as well because I have a mini fridge I'll be running in my truck for an upcoming vacation and I'm very excited to see how this power station works with it! So far so good!

This is my introduction to small power station. Working in video production brings me to locations outside where there's no convenient power and a generator can be noisy. This is a great tool for being able to charge my batteries and if need be plug in LED lights to get longer running times. I also like that it uses LifoPo4 batteries and is quick to charge.

I bought this for camping, but have ended up using it around the house where there isn't a convenient outlet. It "just works" to give you power where you need it. I deducted one star for the confusion on what I thought was an included USB-C charger. There is no USB-C AC adapter in the box, the advertised "fastest charging" method is via a USB-C charger you supply plus the AC charger they supply.

This thing packs a punch! It has lots of power options including 4 110v outlets, which is more than many other devices I checked out. With Anker's reputation, I expect that it will last a long time. I also got the carrying case, a nice addition. It's built well and will protect the PH on trips.

I only gave it 4 stars for one reason. It says in the description and specs it can power a CPAP machine. The reason to knock off one star is the noise the unit makes when being utilized as a battery backup for the CPAP machine. It kinda growls when the CPAP is plugged in and I'm trying to sleep. Otherwise, it is a very good battery backup and portable power device.
