I just bought the Anker Powerhouse 535 last week and took it camping this past weekend. This thing worked great, the charge did not go down a percentage when not in use. It was fast to recharge and I only used my car adapter to recharge. I will be getting the solar panels so as not to use up my car battery when recharging. I loved how the display told me how many hours I had left of the battery because we used it for powering a projector at night to watch movies. We could determine what movies to watch based on battery life left. I felt the durability of the product was solid I never felt like it would break by getting bumped on the table, of course I was very careful to make sure it was not dropped and when not in use was in my car the whole time. Can't wait to continue using it around the house as well. Definitely recommend this product.

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!

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.

Great packaging-double boxed well and thought out with foam inserts. The 535 POWERHOUSE is flawlessly made & very intuitive -except for the power save switch. Charged up with wall outlet in two and a half hours. I did not use an additional UBC cord as I was not u in a rush. Also arrived sooner than I expected. Good service. I have already recommended to an out of state friend to buy one.

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.

Living in a semi-rural area, power outages can be an issue during certain times of the year, so I purchased this for emergency use. I have come to trust Anker for their quality control and sturdy build. I don't have to worry about their products failing catastrophically and causing a fire or other damage like other aftermarket products that are cheaply made. PowerHouse 535 ------------------------- Pros: -Sturdy build, good price, lightweight -Easy to understand display -Plenty of ports for use -Plenty of charging options Neutral: -Not a dig to Anker, but in the end it's still a battery. So it will slowly become less efficient til finally being unusable Cons: - No negatives at this time. I recently purchased so haven't had the opportunity to test it a whole lot Final Thoughts: -Keep in mind, I purchased this for emergency power outage use. It is also marketed towards camping and outdoor activities, which I think it would do well at considering its size and no noise pollution. -Get you one if you are in the market and the capacity fits your needs, especially while they are going through all the holiday sales.

Build quality and looks are what you see first with this product. I purchased as a back up for simple things around the house and for when I'm camping off grid to help spare the camper battery banks for more vital needs like heat and AC. This little pack is small but mighty. Powers the outdoor lights and recharges the phones for a long weekend away. And still has plenty of power left to keep going. Anker customer service has also been top notch. They helped with shipping issues and worked to make sure I was happy and impacted as little as possible. I'll definitely be buying again from them.

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.

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 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.
