Good it solved my purpose of charging a router power bank for my Yamaha and I have ordered one more, who ever found it’s a useful product, waiting for the other one and I’m expecting the same things will keep you all posted Good luck

Before buying this product if want to use for the router pease check your power bank output voltage lots of power bank output voltage is only 9v/2Amp so if you want to use in this type of power bank it will not work your power bank need to have voltage output of 12/1Amp then only it will work I had connected in the laptop USB ports it's works well in it

Good product
