The AKD K-Pin is packaged in a flip-top box and comes with a comprehensive, multi-language user manual, micro USB cable, and two SSOCC coils. Both have a resistance of 0.2 ohm, so no option straight out of the box for variation. However, SSOCC replacement coils are widely available in 0.2, 0.5 and 1.5 ohm and should work with the K-Pin tank. As you can’t vary the output of the mod, I wouldn’t go over 0.5 ohm, however.
In line with current trends, Kangertech has released two versions of the K-Pin – a 4 mL and 2 mL “TPD compliant” version. Now, to truly pass TPD compliance tests, the 2 mL tank would have to be leak-proof, resistance to breakage, and feature some kind of child-proof lock. The K-Pin tank is encased in metal housing and thanks to its top-fill method indeed seems watertight. However, by simply unscrewing the mouthpiece/integrated top cap you can access the fill chamber (great for vapers, not so great for jumping regulatory hurdles). Kangertech may have to tweak their design if they really want a device that can be sold on the EU market.
The tank and battery are detachable, so both parts of the K-Pin can be used in other setups. The mod itself can power coils down to 0.15 ohm. The airflow ring is located at the top of the battery unit. This consists of three evenly spaced inlets, 6 mm wide by 2 mm tall. This airflow is non-adjustable, so you’re stuck with it as is.
The K-Pin has a smooth, medium-glossy finish in a variety of colors. The sample we received came in blue (more like teal). All other detailing is finished in black. The build quality of the device seems solid, with no loose connections or button rattle. The micro-USB port is located on the side of the device, on the same level as the firing button. I like side-mounted USB ports. No laying the device on its side to charge it! The 2000 mAh battery went from empty to fully charged in about 2 hours.
There is only one button to operate the K-Pin. Five clicks turn it on and off. Press to fire. The button sits practically flush with the device, and is set into the black tab running along the length of the battery unit. Remaining battery life is displayed in the form of five small LED pins towards the bottom of this tab. They remain lit for as long as you hold down the firing button.
I was a bit confused by the mouthpiece at first. The outer ring has three indentations which can be gripped. Slide counter-clockwise, and the actual mouthpiece telescopes out. Kangertech claims this aids “hygienic and freestyle vaping”. However, for a simple starter kit the mouthpiece is finickity, tricky to disassemble, and there’s no 510 drip tip adapter. On the plus side, as Twisted points out, it is definitely something to fidget with if for some reason you don’t have a spinner yet!
