Yocan UNI Cart Battery Cooks Oil Vape Carts The Yocan UNI is a cart battery that has everything you look for in a small vape battery.  With a battery that packs a whopping 650mAh capacity and three variable voltage settings; you have all the power you need to vaporizer oil in 510 thread vape carts. While the power is great, the functionality is better.  This is highlighted by its adjustable vape cart height and width.  Standing approximately two-inches tall, the aesthetic of this cart battery has a comfortable in-hand feel that is highly concealable.  Going back to its functionality; there are two stand out features.  The first is the adjustable height switch located near the bottom of the device.  This switch allows you to conveniently move from half ml to 1 ml vape carts.  The second is a twist-action dial located at the top of the device.  This dial lets you essentially lock your cart in place so that it is secure and does not wiggle around.  With this you have both the security of the magnetic attachment and the grip comfort of the twist dial. Additionally, you have a viewing window so you have a visual que into the amount of concentrate in the vape cart you are using. Some additional features include a 10-second preheat function, 3-level variable voltage to adjust power settings for thick oils and wax, micro-USB charging, and magnetic attachment.  The variable voltage of this cart battery takes you from 3.4V to 4.2V and uses a three-light LED system to display which power setting is active. And, if you need a little kick-start to get your concentrates liquified you can preheat with a quick 2-clicks. There are plenty of 510 thread cart battery options on Vapebatt.com to choose from, but the Yocan Uni is an affordable, entry-level oil vaping device from a brand that is reputably known to manufacture quality products.   Yocan UNI cart battery features: 650 mAh Battery Capacity 3-Click Variable Voltage with Light Indicator 2-Click, 10-Second Preheat 510 Thread Vape Cart Magnetic Adapter Micro USB Charging Push Button Functionality Vape Cart Viewing Window   Yocan UNI cart battery contents: 1 – Yocan Uni Cart Battery 1 – Magnetic 510 Thread Vape Cart Magnet Adapter 1 – Micro USB Charging Cable 1 – Instruction Manual
