I bought 2 of these and just unboxed 1, came packaged very well, really nice looking unit, came 30% charged... They claim 662 watt hours which is mind blowing for the price, but even if it's half of that in reality it's still worth it.. So far I'm glad I bought 2 of them and I'm tempted to buy 2 more.. But I will update after I run it tomorrow, but so far I really like it, it's built really solid.. After charging and running some things on it I'm really happy with the one I unboxed, so impressed I pulled the trigger and bought 2 more, however I will say the price went up from 199 to 229, not crazy about that so I went over to eBay and found 2 over there for 199.01... so I have 2 more coming... I have a large off grid solar and wind system I installed about 5 yrs ago, still runs great today , I used hybrid car batteries for my 3 battery banks, so that being said I didn't buy the solar panels for these because I can just plug them into a wall receptacle and use my off grid system, I have one set of panels I got with my other small power station.. I got these not really for myself but for my parents and other decent people to borrow and use in case things go dark in this country for a while... But also instead of running my big battery banks down at night one can take one of these using a double male end cord that's easily made and back feeding the power into your breaker box you can power one side of your breaker panel to run your lights and Internet, this is not really made to run refrigerators and big things but it would run LED lights, Internet and a fan for quite some time, possibly all night, therefore saving my much more expensive electric car batteries... I will update this in a day or 2 when I really test these power stations, but so far very impressed.. UPDATE: I have back fed 1 fremo into my off grid solar breaker panel, a few observations.. From 100% I powered my home lights, Internet and a deep freezer, it took 3.5 hours to go down to 50%, so theoretically it could power the lights, Internet and my deep freezer for 6 hours, and that's only 1 fremo... I can actually run 2 fremos at the same time, so this could get me through the night in a grid down senecio .... Secondly, this does not put out pure sine wave power, not a big deal for me but may be for others, the lights are dimmer when powered by this, but nonetheless it's better than no lights. And I don't have to drain my big battery banks down. I still recommend this power station for the price they are asking, I believe it is a really good deal. I will update again after tonight, tonight I plan on running 2 fremos, 1 powering one side of the breaker panel and 1 powering the other side..and see how it does thru the night, I'm going to guess they will do quite well.. LAST UPDATE:... it is now 9/21/2025... All 4 of these are still going strong and working great. Right now where I live we are in a severe drought and a lot of people are hauling water i use 1 of these fremos to power a small water pump to fill a 55 gallon drum when I haul water it powers the pump and I can fill that drum in a few minutes and it only takes 2% of the battery life to fill it. Also I have fed 2 at the same time into my panel and together they will power lights, internet and my small deep freezer all night. We also had a 6 day power outage about 2 months ago and I lent them out to trustworthy people and they were all amazed at how something so small could power so much, many upon bringing them back have started that were going to be buying some because they are way better then a gas generator and work great running in conjunction with a gas generator. One also saying that they are a lifesaver. I hope all this helps people decide to get 1 or 2 of these, solar generators have come a long ways and are quite affordable, just because something is considerably cheaper doesn't mean it's junk.

Updated Review 9/29/25 (One year plus...) I have had this powerstation for over a year now. I use it daily to charge any and every rechargeable device I own. It is still working flawlessly. Using a 100w solar panel to charge on the weekends. Depending on the sunshine that day, it actually does charge pretty well. As it does have pass-through charging, it allows us to charge the station at the same time as we charge or run our devices. This helps to keep it from running down. Example: If I am using 20w of charge and the station is receiving 40w from the solar panel, then there is not much loss. This is one of the best power stations I have owned or tested. Highly recommend it. Updated Review: (7 mos.) After seven months using it daily to charge phones, lights, tablets and everything usb rechargeable, I can honestly say this power station really does work amazingly. I definitely do recommend. This is a very good power station. So far I really have to say it is a good power station at a very reasonable price. It looks it is so esthetically pleasing that you can even use it any where in your home. Most importantly, it has a large wh and watt and mah capacity. It charges your devices very quickly and can charge many at a time. It has 2 Type C charge port and 4 USB ports. And two plug in receptacles, and cigarette lighter port. The removable light it comes with works ok. I do like that it can be removed and used independently. The information display is easy to read and lets you know how much power you are using and have available. It charges quickly by wall plug, however, it is slower to charge via solar panel (of course that also depends on a few factors such as solar panels type, wattage, positioning sunlight available and so on). So, a way around that is to keep it connected to a solar panel during the day, even while you're charging or running another device(s). It does support "pass through" charging. -In case of poweroutages, Keep it charging during day but car lighter plug or by solar.- Also, if you do not let it go below 80% - 50%, solar recharging will, then, not take so long. -You can use it while it charges. It will work for just about anything that is usb powered/rechargeable and plug-in (within watt capacity listed). It also functions as a UPS device. Helps to keep you from losing any information you're working on and and the power goes out. It will automatically switch over to station for continuous power. It is also great for outdoor activities, camping, and power outages or anywhere where there is no electrical outlet. So, far I do find it to be a very well made and useful product. IT USES LIFEPO4 BATTERIES which are safer and have a longer life. Tip: not allowing your station to go below 25% power before recharging, will extend the battery life. This applies to most rechargeable batteries and devices. I will update as time goes by... Would definitely would buy again. Read more

I like this power bank. Screen is small but gives all the info you need, and the color LCD is a nice touch. Powers everything just fine. This x700 powers 650 watts with a surge of 1000 watts. Some devices like drills, saws, blenders etc will surge to a high wattage then immediately come down to running wattage. So check the items you want to run off it and look at the wattage they use. With 665WH on the capacity of this unit, that means if you plug in a device using 650 watts it will run for an hour... 325 watts would run for 2 hours, and so on. And NO, heaters are not meant to be run off any size power bank. They draw anywhere from 900-1500 watts so even the huge power banks might only run them an hour. As others mentioned, get a heated blanket... they draw about 40-90 watts and once the reach temperature they cycle on/off so they will run a long time. I found the included charger can get pretty hot. But, I also found Dell brand chargers will work with it, so I bought a 240 watt Dell charger that has been working just fine and does not get as hot. Also bought a small DC adapter set here on Amazon so I can use my 60 watt solar charger on this. One nice feature of this x700 is pass-thru charging. That means you can charge the unit and it can still be powering devices at the same time. You can use it as a UPS, but power banks are not meant for that so it is generally not a good idea to keep it connected as a UPS all the time. Only other negative I would mention is the removable light. Works just fine when connected, but the only time I tried to use it detached it only lasted about 25 minutes. Maybe mine is just bad, but I have plenty of flashlights which I recommend anyway... just get a couple of USB rechargeable flashlights and you can charge them off the main unit. Read more
