5V 3A Dual USB Solar Panel Batter Regulator Power Charge Controller Black
A part of the review has been auto-translated.
very useful device if you have a solar panel. it comes with 2 usb 5v entrances. you can charge on daylight cellphone, small fans, radios etc. recommended
Good product . Fast shipping .
I couldn't test it. Plugged in my 10w panel, noticed the 5v output, but the phone and nothing charges. Maybe the panel is too weak. Anyway, it was money thrown away.
Component comes disassembled to facilitate cabling. It has two USB outlets and points for welding the input cable.
Seems a tiny device to use with a small panel. Not tested yet
Very good. They see with the screws and the sticker where they indicate the USB ports and the voltage and amperage. very simple to put together. I'd recommend it. Note: the cables and connectors do not come with the product, I assembled it.
I got it yet I haven't tried, otherwise it looks good
All right
Very Good Item 5***** stars
decent product.
