Whether you're replacing a lost cable or adding a spare to your kit for training or travel, this accessory ensures you can keep your CORE powered and ready. The magnetic attachment makes charging simple and reliable, with no need to fiddle with small ports or risk water damage from exposed connectors.

Charging from empty takes approximately two hours. Once fully charged, CORE can operate continuously for 5 to 6 days while actively transmitting. It’s an ideal back-up for athletes who rely on their CORE for daily training and monitoring, providing peace of mind that power is always within reach.

For best performance, always use a powered USB port. Due to the device’s low current draw, portable battery packs may not recognise or activate when attempting to charge the CORE.

This magnetic cable connects seamlessly to the dedicated charging contacts on your CORE device. The magnetic interface ensures a watertight seal and reduces wear on the device’s port area. Its low-current power draw supports safe and efficient charging, though it requires a stable power source like a USB wall adapter or computer port. This design ensures continued waterproofing while maintaining performance and durability over time.
