I have many electronic devices like trimmer power banks and mobile phones, so I was searching for a USB hub. this USB hub is compact in size and has total 8 ampere of output. this technology combines to deliver device agnostic charging with coordination to the cable. this hub identifies the cable resistance and provide the current accordingly. Total weight of this product is 130 gram which seems very lightweight and easy to carry. inside the box you get this USB hub with power cable. it gets easily fit into any backpack. I am able to charge my 5 devices simultaneously. this product has one year industry warranty which is good. there is nothing that I did not like about this product. if I find something I will update here.
