EnergyFort USB4 240W USB-C Keychain Cable — 8K@60Hz/40Gbps

Single pack: 1 cable in your selected color, with its storage holder and clip ring. The paired product photos show the same cable in different storage states; they do not show a two-cable bundle.

A short USB-C cable for a power bank, nearby SSD or compact travel setup. The EnergyFort USB4 Keychain Cable combines a flat 13cm cable with a removable storage holder and metal clip ring. Unclip it when needed, connect its two USB-C plugs, then return both connectors to the holder for carrying.

Supports up to 240W USB Power Delivery charging, 40Gbps data transfer and 8K at 60Hz video output with compatible equipment. Charging, data speed and video support are separate capabilities; your charger, device ports, storage and display determine the result.

Compact connection, ready to carry

• Keychain storage: attach the clip ring to keys or a bag loop and keep the connectors seated in their holder between uses.
• Short, flat cable: useful when the two devices sit close together, such as a phone beside a power bank or laptop beside an external SSD.
• USB-C at both ends: direct wired charging and data connection, with no detachable charging tips.
• Three colors: Black, White and Yellow have the same listed connection specifications.

240W charging: check the power source and device

The 240W rating is the cable's supported maximum, not the power delivered to every device. Higher-power charging requires a compatible USB PD EPR charger and a device that accepts the negotiated power. A phone, tablet or laptop draws its supported level; replacing a cable does not increase an adapter's output. Use a USB-C power bank output, rather than an input-only port.

40Gbps data, SSD use and video

Up to 40Gbps is a connection capability. Actual file-copy speeds depend on the host port, SSD/enclosure, negotiated mode and workload. A slower USB device remains slower when connected with this cable. Compatible USB4 and Thunderbolt 3/4 setups can use the cable, but verify the required mode on both devices.

Video output up to 8K at 60Hz requires a suitable video-capable source, display and any adapter or dock in the path. A USB-C connector or 240W charging label alone does not establish video support. Multi-monitor operation also depends on the computer, operating system and dock.

For supported iPhone Pro external ProRes recording, check the exact iPhone model, recording mode, SSD sustained write performance and power requirements. Secure the drive separately and test the full recording setup before use.

Specifications and package

Before you buy

Check the distance and direction between your ports, including any phone case or laptop stand. Choose a longer cable when the devices cannot sit close together without tension. Rest a power bank or SSD on a stable surface rather than hanging its weight from a device port. Grip the connector housing when unplugging, and inspect the cable and storage holder regularly.

Questions before you buy

Will it fast-charge my USB-C phone?

It can carry compatible USB-C charging power, but the phone and charger must support the required charging protocol. The 240W rating does not promise 240W phone charging or every brand's proprietary fast-charge mode.

Will every SSD transfer at 40Gbps?

No. The host, enclosure and SSD must support the relevant speed; file-copy throughput is lower than the connection's headline bit rate.

Is the keychain holder a battery or charger?

No. It stores the cable's connectors. Connect the cable to a separate power source for charging.

Is it a two-pack?

No. Each selected color is a single cable with its holder and clip ring. The paired product views illustrate storage and access.
