The 2nd Gen of Geekvape Tri-proof Tech makes Solo 2 a more protective and durable companion outdoors. IP68 rating water & dust resistance and higher level of shock-resistance – stronger protection in a severer environment. Powered by external 18650 single battery, Solo 2 provides a convenient and long-lasting vape experience. Type-C charging port with flip cover enables a faster and safer charging. The accidental press protection design makes Solo 2 safer to carry. A simple swipe up/down switch protects you from coil over-burning or mod over-heating caused by accidental press. A bigger screen provides a better visual experience. Along with the new design UI, the vaping info becomes more intuitive.
