Anker 643 USB-C to USB-C Cable uses a 3-foot silicone design, supports up to 100W, and carries model A8552. Its 25,000-bend lifespan and 18-month warranty set its practical limits.

Anker 643 USB-C to USB-C Cable (Flow, Silicone) is the US name for the 3-foot PowerLine III Flow cable identified by model A8552. Its soft silicone jacket, copper-and-graphene construction, and USB-C connectors put charging durability ahead of display connectivity.

Model And Charging Details

The exact 3-foot model is A8552, and the cable uses USB-C connectors at both ends. Anker lists up to 100W of Power Delivery charging when paired with a compatible high-speed charger.

The cable is designed for USB-C phones, tablets, handheld devices, and laptops. Listed compatible devices include MacBook Pro, MacBook Air, iPad Pro, iPad Air, iPad mini, Galaxy phones, Google Pixel 3, and Nintendo Switch, while LG V40, LG V30+, LG V20, LG G7, and Lenovo Yoga 14s are listed with limited charging speeds.

Soft Silicone, Heavy Strain

Anker describes a triple-layer structure using copper wires, flexible graphene, and silicone. The manufacturer gives the cable a tensile-strength rating of 220 lb, or 100 kg, and a 25,000-bend lifespan.

The included silicone strap keeps the 3-foot cable coiled during storage. The package contains the cable, silicone cable tie, welcome guide, and an 18-month warranty; Anker states that a travel pouch is not included.

The cable does not support media display, so it is a charging and data accessory rather than a USB-C video cable. That distinction separates it from USB-C cables designed to carry monitor output, even though the connector shape is the same.

Price And Category Context

Anker's US listing shows a price of $13.99 as of 09/23/2026. A US retail listing for the 3-foot A8552 model shows $15.99 and confirms the one-count package, 3-foot length, 100W Power Delivery rating, and 18-month warranty.The retailer listing also identifies A8552 as the manufacturer part number.

The closest internal comparison is Anker's newer 240W silicone USB-C cable. Independent coverage describes that model as an upgrade over the older 100W 643 cable, with the same 25,000-bend and 220-lb durability claims, while the charging ceiling rises from 100W to 240W. The 643 remains the narrower choice for devices that do not require more than 100W.

Verdict For Charging Setups

With a 3-foot length, 100W ceiling, 220-lb tensile rating, and 25,000-bend lifespan, Anker 643 is a compact USB-C charging cable for phones, tablets, handheld consoles, and compatible laptops. Its limits are explicit: it requires USB-C charging equipment and does not carry media-display signals.
