Soshine Mini Solar Panel - USB Solar Panel Charger 5v 6w with High Performance Monocrystalline for Camera,Water Pump,Small Fan,Bicycle,Power Bank,Camping Lanterns

This is the second set I've purchased. 1st is still functioning well. Put them on Dash over in car and use to keep items (rechargable vacuum, tire inflator & other USB items charged after use rather than counting on speratic charging when car is in use. Just love em. Purchased this second one as more & more USB rechargable items are in use to need charging.

Panel tested with multimeter and matched promised specs on label. Just charged a USBC device successfully

I tried to charge these solar panels for days in direct sunlight. I used my phone charge to see if it worked but it did not. I tried hooking the panels together for more power but they still did not charge my phone. Now I am trying to return for a refund and lo and behold I have to find a UPS return place around my location. When I did they wanted to charge me $4 for printing out the QR code which I would love to print out my own but there is no simple option to do it so I guess I will keep looking. This one star rating goes for Amazon too! Why make it so complicated to print a shipping label? Oh I guess cause you want to keep the money when I get tired of trying to figure out how to ship the junk back!!!

As far as a value for money goes, this is perhaps the lowest dollar per square inch panel on Amazon.The only catch is that the USB voltage drops well under 5V when the panel is partially blocked or the sun is not out. Many devices will handle this OK. In my case the device it was connected to (a security camera battery charge controller) would go wonky and restart...restart...restart... when the sunlight was not sufficient to power it fully.

In the California Sun in May, I recorded 0.82amps at 4.5V, which equates to 3.7 watts. I know that's not the rated capacity, but that's about right for a 6-watt panel (60% of rated capacity). I wish I could figure out how to open the connection panel so I could shorten/resolder the USB cable. every gram counts when backpacking. Very sturdy. Too hot to touch (140F) after an hour of charging, with air temperatures at 85F. I weighed it at 8.2Oz. If we could remove/shorten the excess wire it would be 7.5Oz.edit: 0.92V at 4.75V = 4.36Watts observedBack panel comes off, but you have to pry it off as there is silicone sealant gluing it all together. I was able to unsolder the USB cable, cut off the DC cable. I then shortened the USB cable and resoldered it to the voltage management board within. I wouldn't recommend this process.edit: I also purchased the "two pack" since the last one was fantastic. Unfortunately one of the two was a different cell design, and only produced half the current of the other. The working panels have two large distinct octagonal cells as pictured. The bad panel was one large rectangular cell. I'll trash the bad panel, the price is still right.

It was able to charge my vape, in direct outdoor sunlight. When any clouds rolled over, it stopped charging. when I connected my iphone and power bank, the charging indicator was on but the device never gained any charge. It’s a small panel, I guess it’s not strong enough. I think if I bought a second one it might work. I probably will return this one and buy a larger one, because I want to use it to charge my phone. I would highly recommend if you live somewhere sunny and just want to charge a small usb item, like a fan, vape, earbuds, flashlight etc. at least where I live, one panel isn’t enough for iPhone or power bank.

I bought 2 of these as an option to keep my Ring stickup cameras charged. Bought additional 10’ cables with barrel connectors compatible with Ring ($11?) that seemed fit for the purpose. Plugged it in and it topped off the camera’s battery from 92% to 100% in an hour. Provided enough wattage that the camera thinks it’s plugged into hard power and prompted me if I want to switch from battery.I tested it with my iPhone 13 and it provided enough power to charge it.Overall I’d say that this product is an excellent option for the purpose as well as providing alternate charging for small devices such as small battery packs or phones for camping/off grid applications.Only drawback over Ring’s $60 panel is that it doesn’t come with any type of mount. Easily fashioned though so…..5 stars overall.

Measurably as advertised, 5V to 6V, it is incompatible with some devices. Good for it being inexpensive, it needs direct sunlight though, a little less and becomes inoperable.
