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

Worked well till someone walked off with it. Charged a phone in 3-4 hours in my window. Works better in full sun at the right angle. Easy to set up. Charging speed is dependent on whether it in direct sun light or not. It will do the job when you don't have power or are away from power.

I bought two of these. They come with the cables you need to daisy chain them together to cut your charging time by half. I plugged my phone into one right out of the box and it started charging in sunlight. At just 6w, these will charge a device rather slowly, so don't expect too much. After 2 hours in the sun I had a 10% charge. With a second panel connected I doubled the amount of charge in the same time. You can also charge two devices at once with the two-panel setup. These are great to have on hand in case the power goes out and you need to keep a phone operational. No power is stored in the panels, so these cannot power lights at night. They are lightweight and thin enough to slip into a backpack for hiking and camping. Also good for teaching kids how solar energy works. A good reminder of how much energy is going to waste. At this price, I highly recommend picking up a pair to keep with your emergency or off-grid excursion kit.

Would rate zero stars if I could. Listen to the other reviews, these solar panels are garbage. Left them in blaring Arizona sun for days & never once worked. Tried multiple rechargeable devices that my other solar panels work on. Neither of the set of two solar panels work. Waste of time, now have to deal with returning it. Cant say anything about battery life, charging speed, power or being waterproof because they didn’t function in any capacity. DOA. Spend a few extra bucks on something better quality.

6w is good for a meshtastic solar node even in overcast days. Performed well during MN winter and storms.

Purchased for use with a Solar MeshNetwork node project. I first tested with a cell phone and was able to fully charge a 4200mah cellphone in about 5 hours of direct sunlight. After confirming function I hard wired the panel into my mesh node (Tbeam 1.1) w/2 1800mah 18650 batteries. I first tested at ground level with the panel angled and facing south, this netted good results and kept the Node charged from 90-100% for 7 days. I then mounted it roughly 18 feet up a tree where I mounted the panel flat against the tree, this is where is suspect my issues started. For the first two days we had decent weather and the panel produced sufficient power to keep the Node running, on day 3 we had heavy cloud cover and the battery dropped to 70% during the day, day 4 heavy rain and it dropped to 40% day 5 rain and cloud cover has it down to 6%. My conclusion is that between the less than ideal angle it is mounted and the minimal sun exposure it is not sustainable without expanding to a larger battery backup to keep it running until blouts of bad weather come and go.

Charges my phone and power bank relatively quickly considering its small size. I measured about 5W output power in direct sunlight. Surprisingly low light threshold; even when cloudy or not in direct sunlight it'll provide a little power. Seems well built and the holes make it easy to clip onto stuff. Overall quite a nice little panel.

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.

Have it plugged into my technaxx tx 168 pro car alarm, sitting on my dashboards. It keeps it fully charged.Wish they made a larger one.
