With speeds of up to 5 Gbit/s, USB 3.0 is quickly becoming the new standard in data transfer technology for PCs and laptops. Some computers have only 10/100 Ethernet ports, while MacBook Airs and many Ultrabooks have no Ethernet ports at all. Existing USB 2.0 Gigabit Ethernet adapters are limited by USB 2.0 to a maximum data transfer speed of 480 Mbit/s, while our USB 3.0 adapter can reach speeds of 5 Mbit/s. Upgrade your 10/100 Ethernet connection to super-fast Gigabit speeds, or enable true USB 3.0 Gigabit Ethernet connectivity on an Ultrabook or MacBook Air. https://elecena.pl/product/18333123/eu-4308-docking-station-port-replicator-usb-type-c 2021-05-05 https://elecena.pl/product/18333123/eu-4308-docking-station-port-replicator-usb-type-c 2026-07-30
