The Coilmaster 521 Mini V2 Ohmmeter is an essential item if you’re planning to build or use rebuildable coils. By using this ohmmeter you can measure resistance and check coils for short circuits or hotspots. We always recommend an Ohmmeter as they have added protections that a vape device doesn’t - so you won’t run the risk of damaging your vape kit or putting yourself at risk.


  • Tests Rebuildable Coils
  • 510 Connection
  • Powered By An 18650
  • Clear Display Screen
  • Compatible With Rebuildable Atomisers

Featuring a spring-loaded 510 connection you can pair the Mini V2 with a wide range of rebuildable atomisers, including RDAs, RTAs and RDTAs. The inbuilt chipset accurately reads coil resistance and you can swap between coil reading and coil testing at the push of a button. It's also long-lasting as it’s powered by a 18650 battery (sold separately).

Featuring a variety of safety functions such as Reverse Battery Protection, PCB Heat Protection and Short Circuit Protection, the V2 is a durable and reliable piece of equipment. It has the ability to measure coil resistance down to 0.05 Ohm, and dry fire coils down to 0.1 Ohm, the V2 can be used with most rebuildable coils available on the market today.

Great piece of kit (30 January 2021)

A must have for building plus it’s a great deck to build on,doesn’t slip at all on my table.
Well worth it

By Ned from Liverpool

Must have. (03 September 2020)

A item that all people who like coil and wick need. Serves as the ideal build station and a must for safety. Comes in a nice box and well packaged. I would recommend this product to anyone.

By KATHY from Bournemouth

Great handy tool (04 February 2019)

I bought this for coiling and rewicking. It really does make life simple. I used to put my deck onto my mod but many times just as I am screwing in coils my mod would slip and fall over so I had to start again. With my 521 Mini I now don't have that problem. It's a perfect height for working and it doesn't slip on your work surface. Highly recommend
