Short answer: Keep nicotine devices and chargers in a secure place inaccessible to children and pets, away from heat and moisture. Follow the maker’s storage directions for each product.

Organize by use
Keep packaging and instructions with each device. Separate damaged units for proper disposal, and do not mix unlabelled chargers and cables.
Check condition
Do not use or charge a device that is swollen, leaking, damaged or unusually hot. Store devices away from direct sun and sources of heat.
For battery precautions, see the FDA battery safety guidance. Follow the instructions for your exact device.
