Let it glow with Glowsticks. This badass battery fits most 510 threaded carts (the most common fitting). It has adjustable temperature letting you choose what kind of hit works best for you. Switch between green (low), blue (medium) and red (high) for a light toke or thick clouds. Preheat your device for a super satisfying hit. A micro-usb charger is included so you can power up almost anywhere.
