This 5-in-1 USB-A hub turns a single USB-A port into everyday expansion for work and travel. You get one USB 3.0 port, one USB 2.0 port, a Micro SD/TF slot, an SD slot (not simultaneous), and a USB-C OTG port for data, earphones, or device charging. USB 3.0 delivers up to 5Gbps so you can import large photo libraries or project folders quickly. Just plug it into your computer—no extra power or drivers. Transfer in both directions: move photos, videos, and documents between cards and your PC, or back up files from your computer to a card for cameras or handhelds. The aluminum alloy shell disperses heat and resists wear, while over-voltage, over-current, short-circuit, and over-temperature protection keep connections stable. It works with USB-A laptops and desktops and pairs easily with keyboards, mice, gamepads, flash drives, and card media. Ideal after a shoot or on a business trip: insert the SD card, connect USB-C earphones for clear wired listening on supported hosts, and keep small gadgets topped up via the OTG port. (Please note: This card reader cannot read two slots at the same time. The specific read speed is related to the memory card!)
