SinKeu G300

I'll admit I'm not one of those who knows the technical aspects of how these works. What I will say is that it's been awesome. 600w there's not a whole lot it can power but I've used it multiple times during power outages for either my CPAP, or my adjustable bed or a small TV plus charging my laptops and phones. The cost is fantastic and for those who can't afford the Jackery, I recommend it.

Oh my gosh!! The best little device charger!! I bring this to my craft shows to charge my phone, my square. & to plug in my party lights for nighttime shows!! It is so lightweight & easy to carry to my shows -it’s a literal life saver for me!! The big bonus light on side is a major plus!! Bright light at the press of a finger!!

Unit works as expected. Battery holds a charge for a long time when not powered on. Runs everythingni bought this unit for. After 2yrs of usage I did have 3 capacitors rupture and our smoke out of the side vent. Went on amazon and bought then cheap and soldered them in and now it's back to working great again. The capacitors were easy to identify because the tops of them are scored to pop opening a failure situation so just look for the ones that have fluid on the top and are bulged up and a tiny hole in the top center. I am pretty sure it happened because I had it plugged in charging and pulling close to 400w at the same time so I won't be using it like a UPS...i just wanted to see if it would work or not.

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.
