VAPEVINE STAFF REVIEW:  “Brass Knuckles makes a simple product look timeless.  This well-built oil and concentrate 510 battery has more than enough power and battery life.  With 900 mAh and 3 different voltage settings, you can take complete control of your vape experience! Reviews Ratings VapeVine

The Brass Knuckles 900mAh battery in Gold or Silver is as compact as it is stunning. The battery itself is only 95mm in length, and 14mm in diameter. We have absolutely no idea how Brass Knuckles managed to fit such a long lasting 900mAh cell into such a small frame. Long gone are the days of the 300mAh herbal vaporizer batteries.

All Brass Knuckles batteries are built with aesthetics and functionality in mind. All features are toggled through the conveniently sized power button. In order to turn the device on, simply press the button 5 times. If you’d like to swap to a more intense vaping experience, press the button 3 times to cycle between the three different voltage settings. The LED indicator on the outside of the button will keep let you know which setting you’re on. Blue is the lowest settings (3.2V), offering a relatively lax vaping experience, yellow (3.7V) is the middle-ground, and red (4.1V) is the maximum power setting.

The Brass Knuckles 900 mAh battery uses a 510 connection, which makes it compatible with all 510 cartridges. To charge the device, screw on the USB charger. Once you attach your cartridge and select your power setting, hold down the power button while you inhale to kickstart your journey.

This 100% Authentic Brass Knuckles Battery comes with:

1x – Brass Knuckles 900mAh Battery
1x – Brass Knuckles 510 Threaded USB Charger

Available in: Gold or Silver
