    I’ve had the Fremo X300 (276Wh) portable power station for about a year now. It’s been reliable whenever I need backup power. Runs smoothly and does exactly what I expect. My only complaint is that it takes a long time to fully charge, but once it’s topped off it holds up really well.

    This portable generator is great. We've already used it for several power outages and outdoor events. Its relatively light and I would definitely recommend.

    This little power bank is absolutely amazing! We got this for the storm power outages we get here in Houston, and this thing came in handy when we got hit with a tornado and had no power for 4 days. It charged 2 cell phones and kept our router working for 9 hours! We were able to tell when we received power back on thanks to this device and our access to our home cameras! I had it for a year before I used it for it's full potential like I did recently. A MUST FOR EMERGENCY SITUATIONS!

    The generator came in handy when we lost power a couple of times recently. I plugged a lamp and box fan into the generator and also was able to keep several phones charged as well as a laptop simultaneously.

    This product was a lifesaver when the power went out during the most resent rainstorm. My lights were out for 4 hours and we used it to watch tv and to charge our phones. I would recommend this item.

    I used my power supply for a trunk or treat a few months ago. It worked great. I was able to plug in a inflatable clown and some lights. Used it for 4 hours and it still had 96% battery left. I'm extremely glad I purchased this power station.
