Wulf - Kodo Pro Digital Battery - $25

Yocan Kodo Star Output Power: After powering on, use the + and – buttons to adjust voltage within the 3.2V to 4.2V range. Full charging takes approximately 50 minutes. Battery level displays in 10% increments; shows 00% when depleted. Preheat Function: While powered on, double-click the firing button within 0.9 seconds to activate preheat mode. During preheat, the screen displays 1.8V. To cancel preheat: Double-click the firing button within 0.9 seconds; Remove the atomizer (screen displays 0 ohms with no load); Hold the voltage adjustment button, then double-click the firing button. Operating Duration: Press and hold the firing button to begin vaporization. The screen displays a countdown from 0 to 15 seconds. After shutdown, the last usage duration is displayed. Release the firing button to stop vaporization. Voltage Adjustment: Voltage can be adjusted while charging, but not cyclically. Simultaneously pressing the voltage adjustment button and firing button disables voltage adjustment, regardless of load status. Low Battery Protection: Output stops when battery voltage drops below 3.2V. Output also stops if voltage falls below 2.8V during use. Short Circuit Protection: Output immediately stops if output terminals short circuit or resistance drops below 0.8O during use. Overvoltage Protection: Low-voltage protection activates when USB input voltage exceeds 6.5V ± 0.5V or falls below 4.0V ± 0.5V, halting charging and cutting off charging current.
