Coil Master 521 Tab Mini

The Coil Master 521 Tab Mini is compact, the perfect size for a vaper to test their coils and batteries on the go. Just because the tab is small doesn’t mean it lacks features. You still get all of the great benefits that Coil Master’s tabs are known for. This includes the ranges, the protection features, and the use of 18650 batteries.

The 521 Tab Mini by Coil Master brand is capable of measuring resistance ranges between 0.01 and 9.99 ohms. It’s also capable of measuring the voltage in a 0.3 to 9.99 volt range. The resistance rate can get as low as 0.1 ohms. To ensure connectivity with almost any tank, 510 threading with a spring loaded contact pin is used.

This product features an ohm meter, coil firing, battery output voltage testing, and a coil rebuilding deck. This is everything you need to test the effectiveness of all of the variables of your vape setups. Then there are the protection features, like reverse battery protection and short circuit protection. This makes the tab safer to use, obviously. The tab is considered mini for a reason; it weighs a total of 80 grams and is 80mm by 80mm by 28mm. It’s small yet capable, perfect if you need to do some tests on the road.
