I recently received the Digiflavor Upen from Geek vape for review.
This battery device is a classy looking vape pen designed for MTL (mouth-to-lung) vapers. It includes a battery cover cap with a clip that can be clipped to a shirt pocket. The entire device actually looks like a writing pen. The magnetised cover cap can be inserted over the battery when not in use.
With my kit was a ego-style battery, the tank portion, the tank cover with pocket clip, and a 18 inch long USB charging cord. There were no spare parts included with my kit, such as a spare coil, spare glass tube, spare o-ring, or a USB/wall plug adaptor included.
The fire switch requires three presses in quick succession to turn the battery on or off. Each time the button is pressed a green light blinks three times when pressed. A red light blinks three times when turned off.
In use, the 650 mah battery lasted approximately 7 hours vape time. The 1.5 ml capacity tank had to be refilled several times during the course of the day. The 1.2 ohm ni-chrome nano coil produced satisfactory and adequate flavor and vapor production which was acceptable for a MTL device. The top cap of the tank could have been designed to be easier to remove to add more e-liquid, in my opinion, since it will need to be refilled so often during the course of the day. (I was using 6mg nicotine in this device during testing.)
This device apparently has "pass through" function, meaning the device can be used while the battery is actively recharging.
Beware: When I first disassembled the tank to prime the coil and add e-liquid, a small white silicone o-ring fell onto my desk. The o-ring apparently belongs on the upper shaft of the nano coil, although the o-ring is not shown anywhere in the exploded diagram of the device. It's my guess that this o-ring is very important to keep the device from leaking.
The kit was found online for about $25. I only found one online vendor who sold replacement coils and they were $10 a piece! That is a ridiculously high price for one coil.
This could be an acceptable device for someone hoping to transition from smoking to vaping, although they would likely need an additional backup device in case their primary device ran out of power before it could be recharged. As a more experienced vaper, I could see myself using this as a stealth vape because of its small size and ability to be disguised as a writing pen.
One huge negative is the price of the replacement coils.
Thanks to Geekvape for supplying this to me for review.
