Banggood

I ordered for some do it yourself project and it works well.

Very good china...it arrived.

ok

works fine,

Good product, fast and easy purchase.

These things are SO handy!

Quite compact; the connector quality is mediocre, but i would not expect high-level stuff at this price. my boards did NOT have any polarity markings for the input lines anywhere (unlike the pictures shown at BG) Although it´s not too difficult to figure out the polarity when you know the USB-A pinout, it would have been so simple just to include it on the mask print. Therefore not 5 stars... Gets a little warm when under full load, so watch for breathing space :)

Perfect Module. Enclosed it in a small inline box and used to permanently wire and power a dashcam in my car. Much better than the bulky Cigarette Lighter Plug that came with the camera and kept disconnecting. Super price, super quality, thank you Banggood.

has a red light that turns on and off when you connect and disconnect it from power feels good when I insert my dongle into its slot

Sweet! now i can regulate the BUCKING USB...this is a time saving and useful component. worth it IMO
