Inline volt meters have been around for years and have been a necessary tool for vapers. Today Madvapes has released revision 2 - and they are about $5.00 cheaper than the original. These are a must for anyone looking to test battery voltage, voltage drop / under load.
THE HARD COPY:
These 3 digit Red LED displays will show the voltage of an attached DC power source with an accuracy of .005 volts!
These are assembled into a small clear tube with 510 connectors and will show voltage of the battery and voltage under load with an atomizer attached. These indicators may not work properly with devices that use switching or pulsing regulators and will just flash. Reads 2.8 to 25.2 volts. Updates at about 2 second intervals.
