Two-Pack USB-A to USB-C Cables for High-Wattage

This two-pack provides 3.3 ft cables rated for 100 W power delivery at 20 V and 5 A. Each cable carries a built-in E-Marker chip and supports USB 2.0 data transfer at 480 Mbps. The aluminium-alloy connectors and nylon braid target users who need reliable fast charging for laptops, tablets and phones without video output.

Sustained Load Behaviour with LED Monitoring

Under continuous load the E-Marker chip negotiates up to 11 V at 7 A to maintain the 100 W ceiling. The integrated LED display reports real-time voltage and current so you can verify that the negotiated rate matches the charger capability. Protocol support for PD, QC, AFC and FCP keeps the negotiation stable across a wide range of power bricks.

Plug-and-Play Installation with Protocol Limits

Connect the USB-A end to a compatible charger and the USB-C end to the device; no drivers are required. Fast charging only activates when the power brick speaks a matching protocol, otherwise the link falls back to standard rates. The cable does not carry video signals, so it cannot drive external displays or dock video streams.

Questions about this item

Does the cable generate noticeable heat when delivering 100W continuously?

The built-in E-marker chip and 7A rating are designed for stable high-power delivery; the aluminium alloy shell helps dissipate heat during extended use.

What charger must I already own to reach the advertised 100W speed?

A USB-A wall charger that supports Power Delivery, QC, AFC or FCP at 20V/5A is required; the cable itself cannot boost voltage beyond what the brick supplies.

Will the LED display work when I plug this into an older USB-A port that only offers 5V?

Yes — the display shows the actual voltage and current being negotiated, so you will see the lower 5V rate on legacy ports.
