Trail Camera Solar Panel 10400mAH, Solar Battery Charger Kit 6V 9V 12V, IP66 Waterproof Hunting Accessory, Fits Most Solar Panel for Trail Cam

Does not work as solar charger
UPDATE: Now the charger will not even provide power to my trail cam, even when I charge the battery pack via USB. . Essentially it is a $40 paper weight, as it will not work as advertised.ORIGINAL POST: Had this hooked up to my trail cam and it kept the cam working, until the batteries discharged. The solar panel was in direct sunlight and did not take a charge. The only way to charge the internal batteries is via USB. Very disappointed. Essentially it is a oversized white rechargable battery pack, which is not what I need or want.

THIS IS THE BEST IDEA!!!
I came across this, and I thought it was to good to be true. I am happy to say that it lives up to everything it makes a claim to be.This package is very versatile.1. You could use the solar panel USB-C connector to connect directly to a camera that has its own battery. The USB-C output from the solar panel is 6 volts2. You connect the two USB-C connectors together and thus charge the four 18650 batteries housed in the unit, and then select either 12, 9, or 6 volts as the output from the barrel connector. I can confirm that you can change those settings, and it works exactly as it should.The back of the solar panel houses up to four 18650 batteries in parallel. This means that you can use either one, two, three, or all four slots with a battery. The more slots that you use, the more capacity that you have. Also, if you are handy, you can figure out how to wire an additional battery pack as well to expand the capacity even more! And for further protection, there is a BMS (Battery Management System) that protects these four batteries from being overcharged, or over-discharged. That is great because if you add additional raw batteries in the future. Then you will not need to worry about those things.Update, I have to add this update as after further testing, I noticed a slight flaw in the design. It appears that while the system states that the solar panel will recharge the batteries via the USB-C connectors when you plug them in together. I have found that is not the case with mine. My batteries went dead after a few days of having my security camera plugged into this for its power source. I then used my desktop DC charger to attempt to charge the battery pack via the USB-C cable. I was able to send a charge anywhere between 5 – 12 volts (The solar panel outputs 5.21 volts), and the amps at 5 volts were 1.16 = 5.8 watts of charge. This did not last long, and after 30 minutes it went down to 0 amps and 0 watts of charging power. It seems that something might be broken in mine, and I will have to fix it. Hence, I need to deduct 1 star from the review because it is not working as advertised. It still works great, and functions off of solar during the day, and then the batteries at night. However, the solar panel will not charge the batteries on mine.

Not charging
I pointed it at the sun for a few days didn’t charge. I then charged the batteries up and then discharged them and tried it again and still won’t charge. The batteries are installed correctly. I am able to power a camera from it, it just doesn’t charge.
