    Helped keep the lights on

    This purchase came in at the right time we had 2 black outs in our area that went into the night and our house was the only one that had light. Once charged, we were able to charge or phone and plug in a lamp. It lasted for more than 5 hours with multiple things plugged in. Its great back up! Looking to buy the larger one later.

    Great item

    Worked great. Took it on a four day camping trip never got below 65%. Used it to recharge our phones and power our night light setup for our site. Used the 100w solar panel to recharge it during the day. Highly recommend

    Exactly what I need

    Decent replacement for my honda generator which I have used in the past - but don’t like the hassle of dealing with gas or running long extension cords. I did do a lot of research and read about what I need for my CPAP when the power goes out and this unit seems like it will run it for a long enough time to where I will no longer have to use my old generator any more.
