    • C400 works well under consistent sunlight.
Style: UD0400+40W
This works well.... especially in consistent sunlight..... The only issue is that the wire that comes with the panel is short....... I most use this during the day..... Under consistent sunlight I am able to charge multiple devices.... computer, phones, power bank and so on..... I also runs my mini starlink on this for four to five hours under consistent sunlight. ... show more

    • Battery recharge super fast, Battery runs down quickly. Terrible packaging
Style: UD0400+40W
I like the UDPOWER solar power station. I purchased it because of the reviews I saw others left. I purchased quite a few different types of solar power station and I think the UDPOWER is the best. I like the fact that it recharges quickly even without the 2 chargers for fast charging. It was able to power my washer, air fryer, kettle, TV and fan separately. It could power my TV and fan simultaneously though. But the battery runs down too quickly. I was able to power my 16 inch standing fan for only 3 and a half hours, I was expecting it would run for at least 5 hours. I haven't tested how long the panels would take to recharge it. In terms of packaging, I don't like the fact that I had to take the power station, the panels and the jumper cable all together just to get either of them. So basically, if you want only the jumper cable, you'd have to take out the panels and power station. If you want only the power station, you have to take out the other two as well. And often time the jumper cable fall to the ground if you don't put box on a flat surface. The packaging is terrible if you ask me. ... show more

    • Worthwhile purchase
Style: UD0400+40W
Really enjoying this purchase so far. Been using it while camping out at night - I take it to my tent and use it to power up a small electric heating pad to help heat up the bed faster. It's great. I charge it indoors during the day so can't say much about the solar charge feature, but will do so once I get set up for it. ... show more

    • So easy and everything I was looking for
Style: UD0400+40W
First time owning a generator. It came charged and ready to use. I’ve so far used it to powered two hanging lights in my shed. All I can say is I’m impressed and glad purchased it. Charging with the solar panel was easy and quick. It also came with power outlet and car cigarette charger power cord and jumper cables. Great value for the product. Should buy if you’re looking for something inexpensive and does the job! Highly recommend! ... show more

Very disappointed with this unit. 1. It takes DAYS to recharge using solar 2. Shuts off when trying to make a pot of coffee 3. Jumper cables included to start a car? That's a joke. 4. Waste of money
