Three small USB-C to USB-A adapters with tiny LED screens

SMUGDESK

SMUGDESK USB-C Female to USB-A 8P Adapter 3 Pack with LED Display

SKU CH-Q349-8YG1K

Three USB-C female to USB-A adapters with built-in LED displays show real-time voltage, current and power during charging and data transfer

  • Real-time voltage, current and power shown on built-in LED screen
  • Three adapters in one pack for spare or multi-device use
  • 8-pin design supports data sync and mainstream fast-charge protocols
  • Gold-plated contacts resist oxidation for stable charging and data transfer
  • Works instantly with phones, tablets, power banks and USB chargers

Three-pack tester for charging diagnostics

This set contains three USB-C female to USB-A adapters, each fitted with an integrated LED display. They are built for users who want to verify the actual voltage, current and power delivered by chargers, power banks or cables during everyday charging or while testing DIY electronics.

LED readout limited to voltage and current

The on-board screen shows real-time voltage and current values so you can confirm whether a charger or cable meets its rated output. The adapter uses an 8-pin circuit that supports common quick-charge handshakes and standard data transfer, but the display does not log history, export data or measure resistance or temperature.

Check port orientation and monitoring needs

Ensure the device you are testing presents a USB-C male plug that can mate with the adapter’s female receptacle and that the USB-A end suits your charger or hub. The unit is a passive inline monitor; it does not boost power, convert protocols or replace a dedicated electronic load for advanced characterisation.

Questions about this item

Should I buy the three-pack or look for a single adapter?

The listing only offers a three-piece set, giving you spares for bench testing, travel and a workshop drawer without needing to order again.

What does the LED screen actually show while I am charging a device?

It reports live voltage, current and the calculated power so you can confirm a charger is delivering its rated output or spot a weak cable.

Does the USB-A 8-pin connector limit the charging speed compared to a direct USB-C cable?

The adapter passes QC and PD quick-charge handshakes through its standard 8-pin layout, so the speed is capped only by the charger and cable you use.
