CARTA 2 — Charging Your Battery

Charging steps

1. 1
   Use the correct charger

   Connect via USB-C to a 5V 2A adapter (standard phone charging brick). Do not use fast chargers or adapters rated above 5V 2A.

2. 2
   Charge when battery reaches ~50%

   For best battery longevity, plug in when the battery is around 50% rather than letting it fully deplete. Press the V button 4 times to check battery level.

3. 3
   Monitor the charge

   Stay nearby while charging. The CARTA 2 takes up to 2 hours for a full charge from empty.

4. 4
   Disconnect when full

   Unplug the USB-C cable as soon as charging is complete. Do not leave the device plugged in overnight or unattended.
