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.

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.

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.

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.

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.

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.

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.

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.

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 like the sleek and simple design. The light is not too bright which is great for the outdoors. It's not too heavy and it's easy to charge.
