At Mascom International, we're seeing steady demand for the UGREEN US276 from IT technicians who service SME offices along Moi Avenue and from cyber cafés that read customer flash drives all day. Unlike other electronics retailers in Kenya who stock unbranded adapters with no resistor inside, we carry the genuine UGREEN unit with the 56KΩ protection circuit that stops a phone drawing more current than its battery can handle. Users consistently report that the aluminium body survives months in a backpack where plastic converters snap at the neck. Walk in and test yours on your own laptop before you pay.

It converts a rectangular USB-A port into an oval USB-C port. You plug the metal USB-A end into your laptop, desktop, wall charger, or car charger, then plug any USB-C cable or device into the open end. That means a USB-C phone cable, a USB-C flash drive, a USB-C SSD, or USB-C earphones can all connect to hardware built before USB-C became standard. No drivers, no software, no settings. Plug it in and the computer recognises the device immediately.

UGREEN's own product page for model 50533, which is the US276, lists 5Gbps USB 3.0 speed. Several Kenyan retail titles carry a 10Gbps label, and UGREEN does sell genuine 10Gbps A-to-C adapters, but those use different model codes. At 5Gbps you still move roughly 200MB per second on a decent drive, which copies a 4GB wedding video in around twenty seconds. Mascom International states the honest figure rather than the marketing one, and staff will confirm the exact SKU in stock.

Charging tops out at 18W, using 9V/2A, with 5V/3A and 12V/1.5A profiles also supported. Qualcomm Quick Charge 3.0 and 2.0 pass through when the wall charger and the phone both support it. That means a Samsung Galaxy A-series or Redmi handset gains a useful top-up speed, not the 45W or 67W rate its own bundled brick provides. The adapter supplies no power itself. Whatever charger sits behind it sets the ceiling, capped at 18W.

No. Video output does not pass through the UGREEN US276. USB-C to HDMI adapters, DisplayPort dongles, and docking stations will not produce a picture, because a USB-A port on a computer carries no video lanes at all. DisplayPort Alt Mode and Thunderbolt signalling are absent by design. For screen mirroring in a Westlands boardroom you need a USB-C port on the source device or a wireless casting option. Mascom International stocks proper USB-C display adapters separately.

Usually yes. The US276 passes USB-C audio, and UGREEN specifically confirms support for Xiaomi and Huawei noise-cancelling earphones on Windows 11, Windows 10, and macOS machines. USB-C headsets for Zoom, Google Meet, and Microsoft Teams calls generally work on laptops carrying only USB-A jacks. The exception is analogue-only USB-C earbuds with no internal converter chip, which may stay silent. Bring your earphones to our Kimathi Street counter and we will test them on a store machine first.

It handles USB-C phones including Samsung Galaxy, iPhone 15 through 17, Redmi, Tecno, Infinix, and Itel models. It reads USB-C flash drives, portable SSDs, and external hard drives on older HP EliteBook, Dell Latitude, and Lenovo ThinkPad laptops. It also carries charging current to Apple Watch pucks, AirPods 3 cases, and Galaxy Buds cases from a USB-A wall brick. USB-C keyboards, mice, card readers, and hubs connect to desktop towers running Windows 10 or 11 without setup.

The gap sits inside the housing. Cheap converters often omit the 56KΩ pull-up resistor, so a connected phone can request more current than the port safely supplies, which damages charging circuits over time. The UGREEN unit carries that resistor, a VIA Labs VL160 controller for stable data, nickel-plated contacts, and an aluminium shell instead of thin plastic. Replacing a phone charging board at a Nairobi repair bench costs far more than the KSh 800 difference.

No, provided you use it as designed. The 56KΩ pull-up resistor follows USB-C specification guidance and advertises the correct default current, which is exactly the protection missing from unbranded copies. The aluminium body pulls heat away from the internal chip during long transfers. The one direction to avoid is trying to charge a laptop's own USB-C port through it, since power flows from the USB-A host outward. Mascom International backs every unit with warranty support locally.

The UGREEN US276 retail pack contains one USB-A 3.0 male to USB-C 3.1 female adapter in a gray aluminium finish, the attached anti-lost lanyard, and printed product documentation with the warranty card. No cable and no wall charger ship with the adapter, since it plugs directly into an existing port. Mascom International stocks UGREEN USB-C cables, 20W and 30W wall chargers, and USB-C hubs separately for buyers building a complete connection kit.

The UGREEN US276 USB-A to USB-C Adapter carries a 6-month Mascom International warranty on manufacturing defects under normal use. UGREEN's own regional warranty support applies alongside it. Claims are handled directly at our Nairobi CBD service desk, with no courier return to a distant processing centre required.
