Authentic GeekVape 521 Tab

GeekVape 521 Tab (Authentic) – $26.23

The GeekVape 521 Tab is basically an ohm meter that can also test fire your coils. This sleek device is smaller than the other popular units out there and has a very nice mirrored finish to it. This GeekVape 521 Tab is able to read resistances between 0.01ohms and 9.9ohms and can fire a resistance as low as 0.1ohms. It’s easy to toggle between fire mode and reader mode with a simple switch on the right side of the device.

Having the ability to read your resistance and test fire your coils to tidy then up all in one device is not only more convenient, but it’s safer too especially if you use unregulated devices. This GeekVape 521 Tab is the slickest looking one yet and a must have for any vaper who builds their own coils. Plus it’s powered by a single 18650 battery which most of us have plenty of lying around!
