The following Delvfire models require a charging cable to charge the battery:
- Delvfire Sirius
- Delvfire Altair
Replacement charging cables for these models are available from our Amazon shop here: https://amzn.to/2TLfiLm
NOTE: All other Delvfire models charge by removing the strap closest to the function button and plugging directly into a USB socket on any computer, mobile charger or power bank.
