Nomad ChargeKey now boasts more power for quick charging and faster data transfer
Nomad's popular ChargeKey USB-C charging cable for keychains pushes up to a stout 240W of power and transfers data at up to 10GBps.
- Small, folding USB-C cable fits on keychain
- Up to 240W of fast-charging power-handling
- Up to 10Gbps data-transfer speeds for large files like photos and videos
- Not a charger
The Nomad ChargeKey, first rolled out in 2013 and periodically updated, just got dramatically more powerful charging capabilities and enhanced data transfer speeds. And the new v2 version comes with a reduced price compared to its predecessor, saving folks about $10.
The new USB-C to USB-C ChargeKey represents a major leap forward from its 2023 counterpart, boosting charging capacity from 60W to an impressive 240W. This substantial increase means the tiny cable can now effectively fast-charge everything from iPhones to MacBook Pro laptops at their maximum supported speeds.

Beyond power delivery, the updated accessory addresses a key limitation of the previous model by upgrading from USB 2.0 to USB 3.1, enabling data transfer speeds of up to 10Gbps. This enhancement makes the accessory particularly valuable for users who need to quickly transfer large files or record camera footage directly to external drives while on the go.
One particularly useful application for Apple users is the ability to charge AirPods directly from an iPhone while mobile, offering a convenient solution for emergency power needs.
Despite its enhanced capabilities, the ChargeKey maintains its signature compact design that allows it to attach seamlessly to a keychain. The accessory features a durable braided nylon cable and electroplated zinc housings, with magnetic tips that secure together when not in use. The combination of ultra-portable design and high-speed charging makes it an ideal backup solution for Apple’s ecosystem of devices.
