USB-A to USB-C charging cable

This USB-A to USB-C cable delivers up to 80W of power and USB 2.0 480Mbps data transfer. It supports Power Delivery, QC, AFC and FCP fast-charging protocols for phones, tablets and laptops. The 3.3ft length suits desk or travel use and the two-pack provides a spare. Video output is not supported.

Sustained 80W delivery with E-Mark chip

An E-Mark 7A chip negotiates 100W PD contracts so the cable can maintain 80W output without throttling during long charging sessions. The thickened connector neck and braided nylon jacket survive at least 35000 bend cycles, keeping resistance low over time. Heat stays controlled because the cable is rated for the full negotiated current.

480Mbps data ceiling

The USB 2.0 interface caps two-way data transfer at 480Mbps, which is adequate for syncing phones or backing up documents but too slow for moving large video libraries. Buyers who need 5Gbps or 10Gbps file transfers should choose a USB 3.x or USB4 cable instead.

Questions about this item

How much heat does the 80 W cable generate when charging a laptop all day?

The cable carries up to 80 W of power, so it will feel warm during sustained fast charging, but the braided nylon jacket and reinforced connector neck are built to handle continuous use without overheating.

What port must my charger or hub provide for this USB-A to USB-C cable to work?

You need a standard USB-A port that supports Power Delivery or QC/AFC/FCP protocols to deliver the rated 80 W; a plain 5 V USB-A port will only charge at lower speed.

Will the 480 Mbps data rate slow down file transfers from my older USB 2.0 external drive?

The cable is limited to USB 2.0 at 480 Mbps, so it matches the speed of a USB 2.0 drive and will not reduce its transfer rate.
