Hello! Does 5v and 12v ports output simultaneously? Thanks!

by BG141521203, on 02 July 2022

Yes they do work together but with a lower power. In my tests I get in direct evening sun (today, 19:00, a bit foggy) about 5 W maximum power at DC output (without USB, 16.3V x 0.3A). With both USB and DC connected I get: 0.2A x 4.2V = 0.85W at DC output plus 4.7V x 0.13A = 0.6W, total about 1.5W. With USB only I get 4.2V x 0.28A = 1.2W. With full sun I expect more power, I will add a review after the test.

A crocodile clip connector has also been added to the solar panel, which can cause the free ends of the tweezers already connected to the solar panel to close at any time. I don't know if this could damage the solar panel.

shorting out a solar panel doesn't cause any harm to it. In fact that exact how you test how many amps the panel can produce. That being said, if this panel really is 20 watts the wires may melt or start a fire if left that way for long while exposed to the sun.

Goods consistent with the description, very fast delivery. I did the panel test on a winter and cloudy day. I recommend the product and the seller.

Excellent quality product (Connect and fabric around the panel). it arrived very quickly. Very well packaged. Not enough sun to be tested but at 190000 lux (cloudy) we have 19.1v and 0.16A output.

Good ideea but I need to open a case for a refund as it only worked for 2-3months max. Now the status led doesn't turn on when in sunlight and the clips show no power output.

Great purchase. Very well packed, good protection. Fast shipment. I just plugged the output to a multimeter, inside the room, no light, no sun, and it worked straight out of the box. Comes with a manual, output cables, as a usb outlet. I got a great price through group purchase, group of 2. Highly recommended.
