SoshineUSB Solar Panel 2Pack with DC Male to Male Cable- Solar USB Charger 5v 6w with High Performance Monocrystalline for Mini Fan,Power Bank,Camping Lanterns

Great Product and fast shipping! Thank you!

I bought this for a portable Meshtastic node build, and couldn't be happier with the performance.

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.

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.

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

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.

They work fine in the sunlight. I charge my phone, a power bank and some rechargeable batteries often, but if I happen to be out til dark and I leave my phone plugged in, the panel actually drains my phone's battery. Seems to lack a blocking diode

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.
