Short answer: If a rechargeable device is low on power, use its documented lower-output mode if available, or stop using it until you can charge it according to the manufacturer’s instructions.
Before travel
Check battery status and the charging guidance for your model. Carry it in a way that protects its controls and charging port; avoid heat, moisture, and damage.
Avoid improvised charging
Do not use a damaged cable or unknown power source, leave a device charging unattended, or open a sealed battery. A lower power mode may change runtime, but no fixed percentage of savings applies to every model.
For battery precautions, see the FDA battery safety guidance. Follow the instructions for your exact device.
