SinKeu G300

I’ve had it a few weeks now and done multiple test with it. It did last a while on a full battery charge even with it being just a normal lithium battery and not the lithium phosphate ones that last 3 times as long in lifespan but it holds up well to my Bluetti’s. What I love the most about it is the light on the back. Its a large light that takes up the whole back of the unit and I like it better like that than what other units do putting it on the front and very small light like a tiny flashlight on front and I don’t like that. So I turned it on near 3 full days ago and set my timer on my phone and I turned the light off after 36 hours straight and it still had half its battery life left but I also charged my ipad, iphone and other android phones and battery chargers too little batteries I have and did that several times off and on during those days too and it held up well and starting blinking the last battery bar signal to charge soon. It was near 3 full days later before that happen during all that charging and light being on none stop. Very impressed with that at least. If nothing else it’s a great glorified light to light up a whole area all night for several nights over. The only thing that made me mad is it lies about watts being used. I have tested all my generators I have 2 bluetti’s and a eco flow river 2 and this one. The others are pretty close to what they say the watts use going out and coming in is. I have a electric watt tester that I plug in for these test. It is always saying it’s in and out putting 10 too 13 watts more than it actually is. Now it may not be a fault in the system it may be done on purpose to count for how much the inverter is pulling in watts off the battery on top of what your device is pulling and calculating it all together but that makes it hard too account what the actual watt usage is as it’s different for every device as some it pulls more watts than others. The bluetti’s does the same but only 5 watts added for its inverter and never changes no matter what device is plugged in. Great device this one is but its all over the ball park at what actually is being used watt wise so I just say a rule of thumb is heavy watt devices will pull 13 watts more per hour than it’s using than small wattage items which is around 9 too 10 watts more cause of the extra power it’s inverter is pulling from it’s battery itself to run what you have plugged in and added to it. So keep that in mind with these electric battery generators it seems they all do this. Makes it aggravating trying too keep the watts right that’s plugged in. So what I do is I find out what the watts is that the unit uses and I always add 13 watts too it and never listen too what it says on screen its always changing up and down. But overall its a good product it works fine and it’s a pure sine wave so you can’t complain. It’s always on sales and offered at a cheap price. Got mine on sale for $120.99. Good price for what you get. Overall I still highly recommend if you want a good one and at a cheaper price. That back light last for days and days that’s worth it alone.

Me and my boyfriend ordered one of these is September of last year. It’s light weight and packs so much power in it. It charge within no time and easy to use. It has two ports for regular plugs and also ports to plug your USB ports in.

Very impressed with this portable power station. The price was great for everything it offers, and the quality feels much better than expected. It’s compact, lightweight, and very easy to carry around for trips, camping, or even as a backup during power outages.

I bought the 300w portable power station in december, and I've only used it 3 times for short periods of time (under 2 hours). Went to charge it this week, and it would only charge to 50% and then stopped charging. According to the product support, it suggests charging it with another AC adapter plug, and I had one that does fit, but it wouldn't charge either. And I don't think I just have to get another AC adapter, the original should work, you know? So I went ahead and used it, hoping that if it drained some, I could recharge again. But no, now I just have a totally dead item. Now I tried to reach out to the company, and the link provided on the "product support" link isn't valid and won't connect to anything, so I'm up a tree with a $120 item that I only got to use 3 times, and no company to talk to to back it up. Don't recommend.

This little guy packs Power strong enough to power my Photography lights for hours. No loss of power in the actual lights at full power easy to carry easy to set up charges fast.

Work's good the only problem I had it didn't come with a charger

This has become a staple for my pop-up vendor events! As a small business owner, I’m often in spaces where power access is limited, and this has been a game changer. I’ve used it to help charge my devices and even power a small fan or heater when needed. Having multiple charging options gives me so much flexibility and peace of mind during long event days. The flashlight is bright. It’s lightweight, easy to carry, and feels durable. Whether you’re preparing for emergencies, camping, or running a small business like me, this is definitely worth having on hand.

We got the 600w battery bank with the 40w solar panel. Today we tested the usage of the battery. We plugged in a 2ft wide, 120v box fan, and the draw on the battery's screen showed about 70w. Quick math told me that with a 296 Wh (watt hour) battery, that my fan should run just over 4 hours. And it did...right around 4hr 20mins. Knowing that the wattage display is fairly accurate, you can easily calculate how long of usage you'll get out of an appliance. My laptop only drew about 20w...so this is perfect for laptops, tablets, phones, or anything that charges via USB. Comparably, I have a USB solar battery I use for my phone, and it has 30,000mAh. It'll run a USB fan basically continuously overnight. This 600w battery is 80,000mAh...so a couple nights of continuous usage on a USB fan is likely doable. Wall outlet charging worked fine. Topped it off when it arrived. I'll be testing the solar panel next, now that the bank is empty. My understanding is that it has pass through charging...meaning you can charge and use the battery at the same time. I also want to test the 12v port with my comms radio. The radio is a 25w, but obviously only pushes that power when transmitting, and a lot less when receiving. I'll test that on my next recharge. Reading other reviews, it appears that the company is very easy to work with if issues arise with their products. Hopefully I won't have any issues, but will also hope that if I do have issues, they can be resolved easily. Overall, I'm happy with this product. I give it a 4 star now, simply because I haven't tested it's range of uses, longevity, or durability. If I run into issues, or I absolutely love this battery, I'll try to remember to update this review. Edit: Ran some further tests. The 40w solar panel charged 40% of the battery in 3hrs...then the sun went down for the evening. That's not bad at all. I finished charging with the wall outlet, and had it topped off in a couple hours. The 12v runs my 25w comms radio fine. Transmitting wattage was dropped a bit, which makes sense. My power source for the radio runs at 13.8v...the 12v socket on the battery runs at 12.2v. The 12v socket is a lower amperage than my power source, and my radio wasn't too happy transmitting...BUT...my power source can also plug into the 120v outlet on the battery, so I can run my radio that way just as I would if it was plugged into my home outlet. So, no complaints there. We will be going in a few camping trips in the next couple of months. If I'm fully satisfied with this product's longevity and durability, I'll revise my 4 star rating to a 5 star. So far, so good. I'm hopeful. Edit...again: I'm ABSOLUTELY satisfied with this battery and solar charger. I've used it multiple times for camping and random usage. I'll likely be buying another battery and panel to store in our emergency supply room. Revised to from 4 to 5 stars.
