The Coil Master 521 Tab Mini is a compact, travel friendly version of the original 521 Tab from Coil Master that makes building your own custom vape coils as simple and safe as can be. 

Coil Master's 521 Mini Tab acts both as a build deck as well as an ohm reader that can actually fire your coils once built, this removes the need to swap your atomizer from the ohm reader to your mod, leaving you with a quick and convenient coil building process.

This device features a 510 threaded connection with self adjusting pin that can detect coils ranging anywhere 0.1-9.9Ω, leaving you with a versatile DIY companion that can handle even the most intricate sub ohm builds.

The 521 Tab Mini is powered by a single 18650 cell (sold separately) that is protected by a set of safety features including low voltage and reverse polarity protections. This device also can test your batteries current output voltage to ensure safe use no matter what when using the 521 Mini Tab from Coil Master.
