Lookah Snail is one of the best 510 thread batteries designed to utilize oil concentrate cartridges such as Exotic Carts, Smartcart, and other vape carts. It is smaller than most vape pen-style batteries and compatible with all types of 510 vape cartridges and is ideal for use with THC or CBD oil carts. The Lookah Snail features a 350mAh battery capacity with a 510 thread connection. The snail doesn't have temperature control heat settings; instead, it uses three variable voltage settings for the facility regulation. This is a similar way many vape mods and ecigs work. The snail is not draw-activated but has a preheat mode.The Lookah Snail features easy single-button operation.Five (5) clicks will turn the unit on or off.Three (3) clicks will adjust between three different voltage settings 3.2V - 3.6V - 4.2V. The integrated 350mAh battery is protected from over-time running, short-circuit, over-wattage, or overcharging. Once the voltage is running low, the LED blinks ten times to remind the user to charge the battery. After showing the low-power alert three (3) times, the system will lock the device until it has been recharged. The Lookah Snail vape pen batteries are charged through the Micro-USB port with a USB adapter at 0.5A. While charging, the LED light remains red, and once it's fully charged, the LED light will change color to green.From fully charged, the Snail has a battery life of about 30 to 40 uses, depending on the battery voltage setting, what type of 510 thread cartridges are being used, and the vaping time for each hit. Lookah Snail can also be used with the 510 cartridges for wax and oil sold on the Lookah webpage. These allow you to vape your wax and other concentrates as you like.
