K3 Kit

K3 Kit
$ 30.00

The K3 kit is powered by a 1200mAh rechargeable cell. The K3 tank is also slightly bigger at 2.0ml whereas the K2 tank can only store 1.8ml of liquid. The K3 Quick Starter Kits come with a micro USB charging cable and a replacement atomizer head. 

The Aspire K3 is a pen-style battery and tank system that is reusable, rechargeable and refillable. 


The Aspire K3 Battery

The K3 battery is the mid-sized device in the Aspire K family. It measures 84mm long (a little over 3 inches) with a diameter of 18mm. To compare, regular cigarettes are 70mm long, King cigarettes are 84mm, 100s are 100mm, and 120s are 120mm.

The barrel of the K3 battery is made of 100% stainless steel covered with a special coating that gives it that cool carbon fiber look.

Inside the device is a rechargeable lithium cell with 1200mAh capacity and a fixed output of 5.5 volts.

Like in most open system vaporizers, the fire button of the K3 is located near the top of the battery so it sits right where your index finger or thumb is when you're holding the device. Click the fire button five times to turn the battery on or off.

Around the power button is a LED ring that glows blue to indicate activation or when the battery is ready to fire.

On top of the battery is a non-adjustable 510-type connector that holds the tank in place. Four inlets are carved into the metal top to let air in.

The K3 battery is charged from the bottom. Use the charging cable included in the Aspire K3 Quick Starter Kit to connect the USB port underneath the K3 battery to a USB power source such as a laptop or desktop computer. If you have a compatible wall or car adapter, you can also charge the K3 battery through an electric outlet or the cigarette socket in your vehicle.

The Aspire K3 Tank

The Aspire K3 tank has four components: mouthpiece, glass tank, atomizer coil head, and base.

On top of the device is a removable plastic drip tip with O-ring seal to hold it in place. You can replace it with any 510-style mouthpiece available on the market.

The middle section is a hollow tube made of Pyrex glass. It can store up to 2ml of e-juice.

Unlike the K2 tank that comes with the old 1.6Ω Aspire ET-S BVC coil, the K3 tank uses a 1.8Ω Aspire Nautilus BVC coil, which is designed to last longer while creating the purest and cleanest flavors. Nautilus coils are very popular so you can easily find a replacement for your K3 atomizer when it wears out. Aspire Nautilus coils are made of Kanthal wire vertically arranged with organic cotton wicks for premium flavors. Around the atomizer are four small holes that draw the juice into the wicks and keep them well saturated.

The base of the tank features four fixed air holes. Although you cannot adjust the size of the holes (like in higher end tanks), the draw is perfect for first-time vapers. The connector underneath the tank has a 510 pin with threads that fit flush into the K3 battery.
