Anker 643 USB-C to USB-C Cable - 100W Charging

Anker 643 USB-C to USB-C Cable (Flow, Silicone) is the US version of the 3-ft PowerLine III Flow cable identified by model A8552. Its soft silicone exterior, USB-C connectors, and 100W Power Delivery rating put laptop charging and everyday device charging in the same compact cable.

Core Specifications

The cable measures 3 ft and supports up to 100W through USB Power Delivery when paired with a compatible charger. Anker identifies the model as A8552, while the longer version uses A8553.

The Flow construction combines copper wires, flexible graphene, and silicone. Anker rates the design for 25,000 bends and tensile strength of 220 lb, or 100 kg. Those figures describe cable durability, not charging speed or data-transfer performance.

Charging And Compatibility

Both ends use USB-C, so the cable connects USB-C chargers with USB-C phones, tablets, laptops, and other compatible devices. The 100W ceiling depends on the charger, device, and Power Delivery profile; the cable does not increase a device's own charging limit.

The cable supports USB Power Delivery fast charging, but it does not support media display. That distinction separates it from USB-C cables designed for monitor connections, and it makes A8552 a charging-and-data accessory rather than a display cable.

Price And Warranty

Anker lists the 3-ft Anker 643 USB-C to USB-C Cable at $13.99 (as of 09/24/2026). A US price comparison listing places the 3-ft cable between $11.99 and $19.99, depending on the seller and configuration.

Anker's cable warranty information lists the PowerLine III Flow USB-C to USB-C cable with an 18-month warranty. The shorter 3-ft length suits desks, chargers, and travel kits; the 6-ft A8553 version provides more reach but is a different length and model designation.

Verdict For USB-C Charging

Anker 643 USB-C to USB-C Cable is a focused choice for charging USB-C devices at up to 100W. Its 3-ft length, 25,000-bend rating, and silicone jacket suit users who need a durable charging lead without display output.

Compared with a basic USB-C charging cable, A8552 adds a documented 100W Power Delivery rating and higher stated bend durability. Its main limit is the lack of media display support, so a USB-C monitor connection requires another cable class.
