I had zero problems with Superbuy, copy the taobao or jd.com url to the top search bar and from there it should be trivial. Now, I do not have the taobao URL to show you but here's an interesting device (takes wide range DC via 5.5mm x 2.5mm plug and spits up two USB C and one USB A connection) https://item.jd.com/36832086035.html and via superbuy https://www.superbuy.com/en/page/buy?nTag=Home-search&from=s... add a cheap old 170W laptop charger from Lenovo with the right plug converter https://www.ebay.com/itm/282597814816 and presto, you have a super high wattage desktop USB charging station.
