concealed 510 battery often come with various voltage levels. Here are some common voltage levels:

1. 5V2.4A, 9V2A, 12V1.5A:
- These are the input and output voltage levels supported by Tesla's 5000mAh magnetic charging case.

2. 5V2.4A, 9V2.22A, 12V1.67A:
- These are the fixed voltage steps of the USB-C port, which can be read by a POWER-Z KM003C meter.

3. 3.4V, 3.7V, 4.0V:
- Some concealed 510 battery allow users to adjust the output voltage with a button press, where green represents 3.4V, blue represents 3.7V, and red represents 4.0V.

4. 2.0V to 4.0V continuously adjustable:
- Some batteries are designed to offer a continuous range of voltage adjustment from 2.0V to 4.0V, providing more flexibility in voltage selection.

These voltage levels demonstrate the diversity and adaptability of concealed 510 battery, catering to different device requirements and usage scenarios. Users can choose the appropriate voltage level based on their specific needs.
