Sunnytech® 2w 6v USB Mini Solar Panel Module DIY Polysilicon Solar Epoxy Cell Charger B032

Third purchase for outdoor rechargeable security cameras. I hooked up the first panel last August to a rechargeable camera with the panel facing south. Since that time, I have not had to recharge it via other means. It will sometimes drop with a lot of overnight activity and / or cloudy days - I have it go as low as maybe 82% or so, but it will eventually get back up to 100%. Second camera is inside my garage with the panel in a window; not performing as well being inside the window glass, but still consistently stays within about 10% (was hooked up at 80%, and stays 72% - 75%. Third camera is my sister's, outside, south facing. Her camera has stayed at 100% since she hooked it up about a month ago. Great value for the price.

The only thing I can say is it wouldn’t charge at all not sure if it’s to weak or just got a bad battery but it didn’t charge anything I left it out in the sun 2 days zero charge rather spend more for a reliable solar charger

I don't get why there's so many bad reviews for this small solar panel. So far it charges a USB dual 80mm fan setup my Huawei phone or any of my power banks and its not even in direct sun. Charging is slower than a battery bank or wall charger by almost half the speed but it will definitely get it done in the many hours of sunlight. I plan to use this to keep a battery bank charged for some small fans I will use to keep an outdoor cat home ventilated.

When Ring abandoned its loyal original Ring customers by selling out to Amazon then rolling out their Ring battery stick up cams, they discontinued the solar panels that worked with the Original Ring Stickup Cams. For those of us who had invested a lot of $$ on the original systems, this was an insult! So, the only replacement available is this off brand 2W 6volt option to replace it. Is it perfect? NO. They will not last as long, but some I have have lasted 3-4 years...some, 1-2 years. The solar surface is the same size as the original Ring solar panel, but without the mounting case. Without the mounting case, attaching to the roof creates the need for a solution. To mount on your roof, you could use mounting brackets like the AOOHOOA Solar Panel Mounting Z Brackets with Nuts and Bolts for RV Camper,Boat,Wall and Other Off Gird Roof Installation,A Set of 4 Units (2 Set). Just be sure to charge your Original Stickup Cam fully as you’ve done before, THEN attach them outside to your solar panel, as they will not charge your Original Stickup Cam from a zero charge. Hope this helps!

Plenty of strong sun, but lacking power. Numerous items say they are charging but don't actually charge from this.Disappointed but kept trying and testing until it's too late to return. At $10 I shouldn't have expected much.

Don't buy! It's a waste of money. It does not work and it has non-returnable policy. I did however go through the hassle to call and talk to an Amazon associate and they were able to refund it.

To be fair I didn't use this for what it was intended for but it's working great for me! I have these little solar walkway lights that only get about 1/2 hour of charge per day making them useless. I tried replacing the batteries but that wasn't the issue. Then just for fun I used some speaker wire to connect them in parallel and attached this larger solar panel to charge a few of them. Now they run for hours! I'd wire regular lights in but the area is difficult to get to with power so this works!

It’s managing to charge my pocket battery bank on an overcast day, so color me surprised.This panel is only suitable for very low power devices. It can drive a small fan decently enough and if you’re looking for a green way to bank power it should do the job with lower resistance batteries.Don’t expect to charge your phone with the panel itself, but you’ll be fine if you pair it with a battery.
