    It screws into your mod and then you put your topper on it and it displays the amps that are being drawn. I believe that's how it works. It's not a multimeter, I already use one to check for shorts, etc. It would be nice to have a real time amp meter ( if there is such a thing). Finally if there is such a device, where would I find it?

    Actually... volts is the display. It's an inline volt meter. The one linked to is just one of several brands and types. Very popular, so when you find one in stock for under $20... might want to buy it.

    Yeah, that was just one I found and it seemed like the price was right.

    Ah so it doesn't measure the amps? I check my batteries religiously with my multimeter throughout vaping especially while sub ohm. I just thought it would be cool to bypass the taking the battery out to check. Thanks for the quick responses!!

    We don't normally measure amp load... but you can easily calculate it because we have known resistances and voltage to work with. The formula is I = V / R (current (amps) = voltage divided by resistance)... so, If voltage is 4.2 and resistance is 0.8... then current (amps) is 5.25.
    Here are a number of links you may find useful, including an ohms law calculator.

    Thanks for the info! I use an ohms law calculator on my phone, but I appreciate the explanation!
