Three-pack USB-C to USB-A 3.0 adapters

This three-pack provides USB-C male to USB-A 3.0 female adapters for connecting legacy peripherals to modern USB-C or Thunderbolt 3 ports. The blue aluminium alloy bodies suit laptops, tablets and smartphones including MacBook Pro from 2016, MacBook Air from 2018, iMac 2021, iPad Pro 2021 and MacBook models from 2020. Each adapter supports plug-and-play operation with no driver installation required. The set is aimed at users who need multiple compact connectors for flash drives, keyboards, mice, printers, card readers or external hard disks.

USB 3.0 SuperSpeed up to 5 Gbps

The decisive specification is the USB 3.0 Gen 1 interface delivering up to 5 Gbps data transfer while also allowing phone charging through the same adapter. An enhanced chipset is used to maintain consistent throughput during file moves or peripheral sync. Connectors are rated for up to 10000 insertion cycles, so repeated daily plugging and unplugging will not degrade the electrical contact. This speed and durability combination determines whether the adapter meets a workflow that moves large media files or backs up external drives.

Passive aluminium design runs cool and silent

With no active electronics beyond the signal conditioning chipset, the adapters draw negligible power and produce no audible noise in normal use. The aluminium alloy casing acts as a passive heat spreader, keeping the connector body at ambient temperature even during sustained 5 Gbps transfers. Reinforced joints and a slim profile allow two adapters to sit side-by-side on tightly spaced ports without mechanical strain. The compact form factor adds no perceptible weight to a cable run and requires no external power source.
