UGREEN US276 USB-A 3.0 to USB-C 3.1 Adapter

Seamless Connectivity Solution

The UGREEN US276 adapter bridges the gap between legacy USB-A ports and modern USB-C devices. This compact connector transforms any standard USB-A 3.0 port into a fully functional USB-C 3.1 interface. The UG-50533 model enables users to connect newer USB-C devices to computers, laptops, and other hardware equipped with traditional USB-A ports.

Advanced Data Transfer Capabilities

The US276 supports USB 3.1 Gen 1 protocol, delivering data transfer speeds up to 5Gbps. Consequently, transferring a 1GB file takes approximately 2 seconds. The adapter maintains backward compatibility with USB 2.0 and 1.1 standards, therefore ensuring functionality across multiple device generations.

Durable Construction Elements

• Aluminum alloy shell provides superior heat dissipation
• Gold-plated connectors prevent signal loss and resist corrosion
• Reinforced cable connection point withstands over 10,000 bending cycles
• Compact design extends only 1.5 inches from the USB port

Power Delivery Specifications

The UGREEN US276 supports up to 5V/900mA power output. However, it cannot replace a dedicated charging adapter for high-power devices. The UG-50533 adapter is designed primarily for data transfer and connectivity rather than serving as a primary charging solution.

Broad Device Compatibility

Connect your USB-C devices to legacy ports on equipment such as:

• Desktop computers with USB-A 3.0 ports
• Older laptop models lacking USB-C inputs
• USB hubs, docking stations, and KVM switches
• Media players, gaming consoles, and TV USB ports

Ideal For These Users

• Mobile professionals: The compact size (0.8 oz weight, 1.5″ length) makes the US276 perfect for business travelers needing to connect modern peripherals to various workstations.
• Content creators: Photographers and videographers benefit from the 5Gbps transfer speed when moving large media files between devices with different connection standards.
• IT departments: System administrators managing mixed-generation hardware can standardize connectivity with the UG-50533 adapters rather than replacing entire systems.
• Home office users: Those with older computers can extend their system’s useful life by gaining compatibility with newer USB-C peripherals.
