Click the button 3 times to cycle through 2.4V → 2.7V → 3.0V.
KYRA VV offers three variable-voltage settings: 2.4V, 2.7V, and 3.0V. The voltage can be changed by clicking the button three times.
Yes. KYRA VV includes a preheat function. Double-click the button to activate preheat, and click once to stop it.
KYRA VV and KYRO share the same 350mAh battery capacity, 2.4V/2.7V/3.0V settings, button activation, 510 threading, and preheat function. The main difference is charging: KYRA VV uses USB-C, while the standard KYRO uses a traditional USB charging connection. The KYRO specification also explicitly lists a bottom LED light.
KYRO MAX VV is a larger, higher-powered version. KYRA VV has a 350mAh battery with 2.4V, 2.7V, and 3.0V settings, while KYRO MAX VV has a 380mAh battery with higher 2.7V, 3.4V, and 4.1V settings. Both use USB-C, feature button activation, support preheat, and use a 510-thread connection. KYRO MAX is also physically larger and heavier at 11.2 × 88.7 mm and 19.6 g, compared with KYRA VV at 10.5 × 82 mm and 16.2 g.
