    Looking for a Tablet USB Hub

    by zaerth ·


    As the title states, I am looking for a USB hub for my USB-C Android tablet, but a regular hub off amazon won’t work for my specific needs.

    I am looking to add 2 – 3 USB ports to my tablet, but the issue is that I need to also be charging the tablet while using the connected USB devices. Most USB hubs that I have found don’t work like this and the tablet either charges or controls the USB devices, not both.

    Does anyone have any suggestions for devices/companies that I should look into?

    Any help is appreciated

      Did not find 3 ports with charging. See and look for the ones that have the word “charging.”

      the issue is the charger or rather the charge protocol:

      The hub uses USB PD to communicate charge levels, which needs an USB-C plug on both sides of the charging cable to work.

      The power brick the tab ships with is USB-A and uses the QuickCharge protocol to communicate the charge level, which the USB-C hub simply does not “speak”, and so the charging is set back to the smallest common denominator: default USB power levels, just 2.5W – 7.5W, so not much -> slow charging, as you’re experiencing.

      You’d need to get any USB-C charger that actually has an USB-C plug on the power brick that can output at least 15W (more is no issue but also no benefits). There are really cheap ones available, I don’t have a suggestion, just look for something that supports USB PD.
