    What type batteries are in disposables?

    Lithium Polymer. Yes, they are safe to toss in the garbage.

    I need a 4/6 port charger

    Review of Charger Xtar WP6 II Review of Charger SysMax/NiteCore i4 V2 Both are going to be relatively slow. xbassman is correct in that the Xtar has 3 channels @ 600mA and the NiteCore has 2 @ 750mA. The way that they handle 2 batteries in one channel is different, but it will significantly...

    Thought I would share this

    I get where you're trying to go with this, but I think it came out all wrong. Watt's Law is not a theory...that's why it's a law. ;) 1 watt is always going to be 1 amp at 1 volt, no matter if you are trying to heat 1 ounce or 1 pound. What you are talking about is thermal inertia; the...

    Thought I would share this

    Power is not an element of Ohm's Law: Voltage, Current, Resistance. Watt's Law utilizes elements of Ohm's Law to calculate power; W=V•A Watt's Law is often lumped into Ohm's Law because if thier close relationship, but they serve two very distinct purposes.

    Batteries, Chargers and Safety...OH MY!

    Why should I let the batteries rest before and after ?

    Mechanical Mod battery Tubes and Conductivity.

    ^^This. For the most part, the surface area and size of the body will negate most of the poor conductivity. "The river is wide enough for ample current to flow". Most of the "problem" is the small surface area pathways in the battery, switch, and atty contacts; the narrow part of the stream.

    Does two batteries really give a better vape?

    The PWM is a 6v/0v on/off cycle. When you get into high power with a single batt, it struggles to make the 6v in the boost stage; so peak output suffers. There is no mAh advantage to stacking battries, but the is a Wh (Watt hour) advantage. At the same power output, battery drain current in...

    Why does the Provari hit differently than the eVic?

    Are you being serious or mischievous?

    Why does the Provari hit differently than the eVic?

    Converts the red line into the blue line. (That isn't a Provari's signal, but it's similar in design.)

    Impressed with these Chinese mech clones

    All numbers are under load. I'm using an inline adapter and two multimeters to take the measurements at the same time.

    Impressed with these Chinese mech clones

    My voltages are under load, taking both measurements at the same time.

    Impressed with these Chinese mech clones

    Comparing voltages at the atty posts between different mods and attys is pointless. Where is the voltage drop; atty or mod? Measuring inline between atty and mod is second best because the drop will vary by battery, but it much more convienient than the best option. Ideally you should take 2...

    ViVi Nova is a perfect fit for the taper.

    Battery Question

    With a mechanical mod the mAh is about the last thing that I look at. You will never use the full capacity because the vape will be so anemic you won't want to vape them past about half charge. Any good 18650 IMR will last the average person at least most of the day; even the "measly" 1500 &...

    AGA-T how to make refilling easier?

    I take out the screw post that is next to the fill screw. Still works with eHuman's filling method and I haven't had any leaking problems. No need to fiddle with tool just to fill the tank.

    Yes. It is threaded and might be a little tight.

    Help with 18350 + 1ohm atty

    AW IMR 18350 is rated for 6 amp discharge. Keep your coils over .7Ω and you'll be good. Xtar WPII is a great charger. You will need 2 spacers per battery for 18350s. I havent seen the rated discharge current for Efest 18350s, but I know that the AW 18350 is a better performer. So...

    GGTS Clone/CCST/Chi Chi Show and Tell

    I never really checked it in stock form, but with some light sanding on the contacts to expose the brass(?) my drop is 0.13V. CGR18650CH @ 4.15V 1.1Ω coil on AGA-T+ 4.02V measured inline between mod and atty. ETA: One thing to note for those that are measuring without an inline adapter (ie...

    Provari on an Oscope vs Vamo

    The values for the equation are in the document, the equation is not. Thermal Inertia Primer Thermal inertia is synonymous with thermal effusivity. Thermal effusivity - Wikipedia, the free encyclopedia
