Anker sells chargers, cables, power banks, hubs, docks, and portable power stations. The products are built for phones, tablets, and laptops, and the product page states the wattage, the ports, and which devices that model is meant to charge.
A charger or power bank is not interchangeable just because it uses USB-C. Wattage, the number of ports, and whether the brick supports a laptop are printed on that model’s page. Docks and hubs add video or ethernet for a desk, and portable power stations are a separate, larger product for running devices away from a wall outlet.
Conferencing gear appears alongside the charging line on Anker’s site. The right pick is the one whose listed output matches the device, not the one with the most ports.
