I would have rated it five stars but out of the box my generator will not charge above 94% and my expansion battery will not charge above 88%.

It's a quiet and powerful power source, 2400w is an amazing power! I use the power station to work with my Travel trailer when we are at places like the beach for day or over night trips . It has been amazing for being able to have an access to our refrigerator and and use of the trailer where we can’t have shore power .

This Anker Powerhouse lives up to its name. I purchased to use as an UPS and be ready to run a fan on my stove, the internet, home alarm and television. It will power all three for about 6 hours. If I chose to conserve power and not use the television it will run the blower on my gas Lopi stove for about 28 hours. It quickly charges while running all of these things. One important thing to know is that you will need at least a 3000 watt generator if you want to charge while using whatever you have plugged in.

Bought this for the family just In case we go through another blackout like here in texas we have plenty, especially in the winter. Quality made and built to last with great customer service experience with Anker. It charged in 1.5 hrs to 100%. Wow!!!

When I got the generator I charged it to 100%. Only took 2 hours using ac cord to wall outlet. Very nicely made. I will try charging with solar panels when weather permits. Great customer service.
