The team at HeavenGifts very kindly sent out the Geek Vape 521 Master Kit V2 for the purpose of this review.

As you progress through your Vaping journey, and begin to start building your own Coils, your going to need to invest in a some tools to assist you, and an Ohms checker, to check the resistance of your Coils, and to ensure they are safe to run on you device.

When I started building a couple of years ago, I ended up putting my own little kit together, normally by beg stealing and borrowing from around the house. All kept together a lunch box.

With this in mind Geek Vape have put together this comprehensive coil building kit,  with nearly everything your going to need to successfully start building your own Coils.

The kit comes neatly packaged in a hard wearing Zip case, measuring 140 x 170 x 30 mm, with the Geek Vape Logo embroidered in one corner.


Once the case is unzipped it opens up and folds out, allowing access to the contents of the kit.


This custom made case allows each item of the kit to be securely held in place, in its own fitted pocket.

The 521 Master Kit V2 includes the following items.

  • 1 x 521 tab mini 
  • 1 x Ceramic Tweezers
  • 1 x Nipper pliers
  • 1 x Diagonal pliers
  • 1 x Scissors

The 521 features a sprung loaded stainless steal threaded 510 connection, to all you to securely screw down all your Atomisers that you are working on.


The right of the 510 connector is the slide switch, that allows you to switch between fire, off and resistance meter.


On the opposite side is the small fire button, that when in fire mode allows you to pulse the coil, it just delivers a fixed wattage to the coil, with no adjustment.


The 521 features a bright orange LED screen, that displays changes depending on the selection, and will either display volts or ohms. There is also a battery level indicator. With three bars indicating
3 = 100%

1 = 30%


The 521 Tab mini is powered by a single 18650 battery, that is secured in place on the underside of the device, underneath a magnetic battery cover.


This battery can be charged when required through the micro USB sock located on the front of the device.


Ceramic Tweezers


Geek Vape have included a set of Tweezers multi grips in with the kit, which have a pair of heat ceramic Tweezers on one end, which allow you to squeeze the Coils as you pulse them, and a tank grip on the other end, which is used for unscrewing those overtightened tanks and bases.

Nipper Pliers 


These high quality spring loaded nippers are perfect for cutting wire to length, and getting into those fiddly places to cut off the coil of tails.

Diagonal pliers

These needle point elbow pliers are perfectly angled for getting into tight spaces, when squeezing Coils, and pulling tails.



Every DIY kit needs a sharp pair of small scissors, for cutting you scrips of cotton for wicking, or trimming the wicks to length, these are nice to hold, and very very sharp.

Coil Jig Screwdriver Set


The reason they have included a screw driver set is not only for screws, but they are the perfect size for wrapping Coils around.


Slotted 1.4, 2.0 & 2.8mm
Flat End 1.8, 2.4 & 3mm

This a great little handy DIY kit, with all your going to need in one once, the items are well made, and great quality, I could be with out mine, and when ever I go away, I slip it in my bag.
