    I travel alot for work and this has made traveling much more convenient. When i want to game on my switch, steam deck or laptop i can pull over, plug in and chill. Its basically a super big battery bank i use for my handheld consoles.

    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 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!

    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 was sort of forced into buying this Fremo portable power station due to an expiring Best Buy credit and a one-day sale. I had been looking at these things since a long power outage last summer, when it would have come in handy. Ideally, I wanted a larger one, but... circumstances. So I bought. (I'd return it, but I'd lose my $50 credit.) I'm not a camper; this thing is purely for extended power outages. It should run a cable modem and router, plus charge electronics, which is good. What it's *not* big enough to do is run a 110V sump pump, a freezer, or a fridge. (It would probably run a 12V backup sump pump, but so would any car battery.) Charging is SLOOOOOOOW. Using the plug-in adapter it came with, it maxes out at 60W, and it takes (many) hours to go from 20% to 100% - like, overnight. I bought a 60W solar panel (because I like gadgets), but it didn't seem to charge this at all; it only registered 1W. (I'm not sure if I should blame the solar panel or the Fremo yet, but I suspect that the Fremo just stinks in all categories.) Draining the battery, on the other hand, is quick and easy. So if you aren't limited by circumstances like I was, I would suggest buying a different brand, which will likely charge up way faster, and get a bigger capacity, which will do more things for you. These power stations are still a better option than a battery + inverter (which I used to run my fridge), but get a good one.

    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.

    Exactly what I was looking for. Last year with Hurricane Ian we were without power for a week. I wanted something small this season. With Hurricane Idalia we lost power again but with this we were able to charge our phones, plug in a fan, and take it where needed. Highly recommend!
