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.

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.

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!

Excellent quality but somewhat confusing on how to use. The owner's manual doesn't provide a step-by-step process on how to use as a back-up or how to re-charge.

Have not used this for long, but from the couple times I've used it, it's helped me to keep several small appliances running to last through power outages. Super simple to setup and use.

This one is for my wife. It is powerful and light enough for her to manage. I haven't started my gas generator since we got the first one. I don't miss buying gas.

I bought this for power outages and got a chance to use it recently. I powered my router and my full-size refrigerator. It worked really well and I was glad to be able to use the internet and keep my food from spoiling.

Works beautifully, charge is quickly, and isn't super heavy! Had no problem, blowing up air mattresses, charging phones, and keeping fans on all night during our camping trip. Highly recommend.

Just what I needed. Ran my CPAP for 3 nights, used 30% power each night. Great to have for power outages and camping.
