Learn More about Smart Battery – 650 mAh Vape Pen - Sapphire BlueThe Hinge is a 510 battery that flips, folds, and disappears when you’re done using it. This lowkey design resembles a utility tool or a car key. Press the button on the side to flip the 510 thread into working position. Screw your cart in and you’re ready to rock.
This is our stealthiest vape battery in a long time. When all closed up, it’s super inconspicuous and fits in with the rest of your daily carries: phone, wallet, and keys. It’s slim and slides right into your pocket. It also adds a layer of protection that typical stick-style pens don’t: it tucks the cartridge into the base, protecting it from drops and falls.
The digital screen is easy to read, and everything is controlled by the power button. Click it 5x to turn on and off. Click it 3x to change the voltage. Click it 2x for Prep Mode, which is a low-voltage heat cycle that clears any clogs in your cartridge. Your battery power is always shown at the top of the screen. Press and hold the button to take a puff.
The Hinge is equipped with pass-through charging, which means you can use it while it charges. Never let a dead battery kill your vibe! This battery has a type-c (universal) charging port, but does not include a charging cable. You probably already have a charger at home! It

The Hinge has a 210 mAh battery, which lasts for about an hour of active use (time spent hitting the pen). This translates to roughly 100 puffs per full charge, depending on your voltage level.
The Hinge has 210 mAh, which is a relatively small battery. You can get about 100 puffs from a full charge, so it’s best for casual use. The good new is that you can use it while it charges, and it charges back up quickly!
Standard size 510 oil carts (0.5g and 1g) will fit in the concealed part of the Hinge. Taller or wider cartridges may have trouble fitting into the closed position.
The Hinge has a voltage range of 2.0V to 4.0V. Click the button 3x to cycle through heat levels. 2.0V is great for oil cartridges, amplifying flavors, and protecting the cartridge hardware. Higher temperatures create bigger clouds.
The Hinge is button-activated, which means you need to press the button to take your hit.
