How to Use Your Battery
Unbox
Remove your Secret Solder battery from its packaging. Each comes pre-charged and ready to use.
Attach Cartridge
Screw any standard 510 thread cartridge into the top. Hand-tighten only — do not over-torque.
Power On
Click the button 5 times rapidly to turn the battery on. The LED will flash to confirm.
Select Voltage
Click 3 times to cycle through voltage settings. Low (green), Medium (blue), High (red). Start low.
Use
Hold the button while inhaling. Release when done. Sessions of 3-5 seconds recommended.
Power Off
Click 5 times rapidly to lock the battery and prevent accidental firing in your pocket.
Best Practices
Start Low. Begin with the lowest voltage setting and increase as needed. This preserves flavor and extends cartridge life.
Short Sessions. Take 3-5 second draws rather than long pulls. Better flavor, less waste, longer battery life.
Keep It Clean. Wipe the 510 connection with a dry cloth periodically. A clean connection means consistent performance.
Store Upright. When not in use, store your battery upright with the cartridge attached. Prevents leaking.
