BLAVOR 30W Solar Charger USB-A QC3.0 24W USB-C DC 30W Outputs, Foldable Solar Panel for Camping, IPX4 Waterproof, Solar Battery Charger Compatible with Solar Generators, Phones, Tablets

I have a 10w solar panel already, but it ONLY has a USB-A connection and is about twice the size and weight of this unit. So, this unit is about the size of a half-sheet of paper when closed, and definitely lighter than my older one, but I suspect my older one is a bit tougher, not that this one won't do the job. This unit has both a USB-C and USB-A port, both outputting the same watts and amps, so you aren't going to get better performance using USB-C. What it does do is allow you to only have to carry around a USB-C to USB-C cord for convenience, though one should have a USB-A cord handy for certain equipment. Seems to work as expected for a 10w panel, as I'm currently testing it. I've found best performance for charging with a solar panel is to charge a battery bank and not to the electronic device directly. Many phones require a specific Amperage and wattage that can't be guaranteed from smaller solar panels. In my testing, my phone would try and charge but stop, just repeating this process causing my phone to get excessively hot. I bought this unit for its cost and size factor. It should be much easier to carry around then my older unit because it's so much lighter, plus the cost isn't so much that if I manage to break it my wallet isn't screaming. Only time will tell how well it holds up, but the form factor definitely makes it nicer for day-to-day use. When testing my old one, I managed to completely charge a 10kmAh bank within a day. That was unattended so I don't know how much more I might have been able to charge. This is probably enough to keep all your electronics charged under normal use.

Plug and play. I leave this in a west facing window and it keeps my iPhone charged.

Small footprint. Works as advertised. Great for charging phones, portable batteries, iPads, etc, and the price is right.

Works great on small fans charged up pretty fast. But not to good on cell phone as showed but overall like it

Be aware that 10 watts is really slow, it takes a couple minutes in full sun to put your phone up 1%. I got this to put in the car window to keep a small fan charged to blow in the back seat at my dog when driving, or to blow out a cracked window when parked. It’s much better than those solar window fans that only barely work in full sun. This charges a small fan battery even in partial shade. It’s good quality for the price, light, and folds up small. Overall, perfect for tiny charging jobs, and suitable for a long hike or short camping trip.

I bought this to surprise my boyfriend who went on a 3 week thru-hike. I thought it would come in handy if his battery pack got low and he'd be able to charge his phone while hiking. He used it one day, intermittent sun in and out of the woods. Took his phone out to check the charge after a couple of hours and his phone won't turn back on. Somehow burned out his battery, his phone will no longer charge. If he was on more isolated parts of the trails he wouldn't have been able to contact anyone. $30 solar panel is now going to cost me the price of a phone. What an absolute waste of money. So frustrated and disappointed.

Great cell phone charger. I take it to the blind with me to keep phone charged.

This is a nice solar panel with an easy interface for the USB compatible devices. I purchased this because the solar batteries in my hurricane kit charge very slowly. I was hoping that this added charging power would significantly reduce the charging time of the batteries. While it helped reduce the charging time, the impact was less than I had hoped. It's a good addition to the solar array for the price, but I need to consider a more powerful solution. The construction of the panel is good and the design allows the panel to be hung in a window with a phone in the back pocket. I didn't return the panel because it will be helpful in the even of a power outage.
