Sunnytech B032 USB Mini Solar Panel: Efficient 2W 6V Polysilicon Epoxy Cell Charger Module for DIY Projects Review

This helps build a small cybernetic tree but still needs an O2 generator to create a cybernetic tree idea. I also need more knowledge on how to build such items. Welcome to my brain ideas and the lack of knowledge I have because the education system didn't think of helping me learn the skills needed for this idea.

Doesn't perform as advertised. I needed this for a 1w air pump in my outdoor pond. According to the specification, this panel should deliver 2 watts, which is double what I need. The pump only worked in INTENSE direct sunlight, but I needed it for more than 2 hours a day. 2 stars as it technically works but doesn't work as advertised. Attention buyers too - this item is non-refundable!

I don't understand why there are so many bad reviews about this little solar panel. It currently charges the dual 80mm USB fan I have on my Huawei phone or one of my power banks, even in direct sunlight. Charging is slower than using a battery pack or wall charger, almost half as fast, but it will definitely endure many hours of sunlight. I plan to use this to keep the battery charged for some small fans I'll be using to air out the cat house outdoors.

Purchased to charge outdoor camera batteries. The open circuit voltage is 7.2V in full sunlight and the short circuit current is 330mA. It appears that a low barrier diode (0.3V) is in series with the cells but is not visible under the back seal of the USB cable. The internal resistance is probably around 22 ohms and is therefore ideal for slow charging of 4.3 V lithium batteries (with an external regulator). It's been up for a few weeks now and works great.

I'm tired of spending $50 each on a ring solar panel to power one of my 4 overlay cameras. That's why I asked this question at the end of February/beginning of March. Does this panel work with a camera with a ring? Nobody could answer my question, so I took the risk of buying a panel. Again, keep in mind I installed this back in March although I'm only now posting a review so I had to use the solar panel for over five months and it works great keeping my camera charged and weathering the…

I like that I don't have to look for or buy separate solar panels for my needs. It comes in a package that you can choose from for all experimental uses. I've used mine primarily to power DC motors, charge batteries and LEDs. Don't forget to remove the plastic protective film from each solar panel to achieve full potential performance. Light sources such as sunlight, incandescent lamps with a power of 100 watts or more are most suitable. An LED light bulb of 100W or more also works quite well…

I bought this solar panel to power my Arlo Pro 2 outdoor security cameras I've read comments here about Revain that are on indicate outstanding success in powering up Ring Stick-up cameras. Everything is fine and great when the panel is in bright sunlight. The panel is also fine without direct sunlight. However, under cloudy skies or at dawn or dusk when there is little (but limited) sunlight, my cameras' batteries drain like a sieve! And while my Arlo Pro 2 batteries don't drain in bright…

When Ring turned off their loyal customers with original rings by selling Revain and then releasing their vertical battery operated ring cams, they stopped making solar panels that worked with the original ring jaws . For those of us who invested a lot of money in the original systems, that was an insult! So the only available replacement is the 2W 6V alternative to replace it. It's perfect? NO. They won't last that long, but some of them have lasted 3-4 years, others 1-2 years. The solar panel
