Manage battery life and swap the Battery Booster

The Pin clips to your clothing using the Battery Booster, a magnetic backing accessory that also holds a swappable battery, so you can extend battery life throughout the day without taking the Pin off.

What you should know

  • The Battery Booster attaches magnetically to the back of your clothing, with the Pin clipping to it from the front.
  • Swap in a freshly charged Battery Booster when your current one runs low, without needing to power the Pin down.
  • Charge spare Battery Boosters separately so you always have a fresh one on hand.
  • Check battery status on the Pin or in your Cosmos account before heading out for an extended period.

Always align the Battery Booster carefully with the Pin's magnetic contacts — a loose or misaligned attachment can cause it to disconnect or fall.

Why it matters

Because the Pin is worn throughout the day, understanding the swappable Battery Booster is what makes all-day use realistic — it lets you extend battery life on the go instead of being tied to a charging cable.

Best practices

  • Keep a second, fully charged Battery Booster with you on days you expect heavy use.
  • Let a low Battery Booster fully recharge before your next swap so you're never caught without power.

Common problems and fixes

Pin loses power faster than expected
Heavy use of voice interactions and the Laser Ink Display draws more power — carry a spare charged Battery Booster for long days.
Pin won't stay attached to clothing
Check that the Battery Booster's magnets are clean and properly aligned with the Pin, and that your clothing isn't too thick for a secure magnetic hold.

Tips and tricks

  • Swap the Battery Booster during a natural pause in your day so you don't interrupt an active interaction.

Frequently asked questions

Can I swap the Battery Booster while the Pin is on?

Yes — that's the point of the swappable design, letting you extend battery life without powering down the Pin.
