    This little power station is great for keeping phones/flashlights/camera gear charged on longer outings/camping trips. I used it to run a 12v refrigerator in the trunk, and you can charge the battery off the car while it powers the fridge. Bought in a bundle with the Anker solar panel, pictured.

    Wanted something to have power anywhere. My main use is with the Samsung Freestyle Projector and Nintendo switch. Have plenty of Mario Kart and Smash Bros on the go. With both I get about 4-5 hours or use. Has plenty of ports. Only wish it had one more usb C port

    It’s portable but the battery life is not ideal for me. Battery only lasted less than 2 hours.

      Thank you so much for sharing your experience. We're really sorry you've encountered this issue!

      May I confirm if you turned off all ports (no led lights are on) when you do not use the PowerHouse?

      When any of the control buttons are turned on, even if no devices are being charged, there will still be a certain amount of no-load power consumption. Please turn off the button when you do not use the Powerhouse.

      In this case, please charge the PowerHouse fully, turn off all ports, and leave it unused for 1-2 days to see if the same issue happens.

      If those don't help, please reach out to us via support@anker.com or call us at +1 (800) 988 7973. We are more than happy to assist you further.

      We offer a5-year warranty for this product, plus lifetime technical support. Our standard for responding to email quests is less than 24 hours, and we look forward to hearing from you! anker
