    Making a USB Passthrough?

    Yes, but it doesn't provide nearly enough amps. You need a 2amp USB power supply, which you can buy from madvapes.

    Making a USB Passthrough?

    It's dead simple. Less than $8 in parts from madvapes and maybe 10 minutes to assemble. I made one about 5 months ago and it's been working like a champ ever since. EDIT: Doh! Didn't notice you wanted a 3.7V PT. It's not much more complicated to do that. A simple voltage divider...

    I Can't Vape!!!???

    I occasionally get sores on my tongue, but I figured out it's because I vape at 5V with a drip-tip, and the atty will occasionally "spit" hot liquid, which burns my tongue. If the sores are throughout your mouth, then this probably isn't the case for you. The Chinese liquid you were using is...

    Are 5v PV's better?

    This is correct. NIMH batteries are inherently inferior to li-ion and LiPo batteries, and these 5V packs (4 1.2V cells for a total of 4.8V) should probably be avoided. For me, 5V is a must. Even with LR attys, I am no longer satisfied with 3.7V devices. I still have a bartleby with a LR atty...

    First Impressions of the NEW PROVARI!!!

    No reason to get bent out of shape. It's a valid point that boost regs are much harder on batteries than buck regs. It was my immediate concern as well when I heard about this mod. I ran the numbers and as long as you use the recommended AW IMR (or other high-drain) cells, you should have no...

    Darwin...Is it really different?

    It's not even as bad as that. The iphone was made intentionally non-serviceable to force you to buy a new phone every couple years. It's nearly impossible to take it apart without destroying the case. All apple products are made like this, and its one of the many reasons technically savvy...

    Strong suction could have adverse health effects. Seriously. I mean...really, seriously?

    Health advise from a country which still has regular (and fatal) cholera outbreaks? No thanks. Figure out how to not poop where you get your drinking water and then come back with the medical safety lectures.

    Longest lasting 2.5ohm 510?

    I got a 5-pack of (supposedly) authentic joye 510s on friday, and I've already burned through two of them. Here's hoping those bauway attys show up tonight and can average more than two days each.

    Darwin...Is it really different?

    Two cells wired in parallel would simplify the charging circuit (no need to balance), but at the cost of overall capacity. Whatever the volume of space the two 900mAh cells are taking up, a single cell in that space would have a higher capacity than 1800mAh. You might use two cells in parallel...

    Darwin...Is it really different?

    There are only two basic types of voltage regulation - switching and linear. This forum, being generally non-technical, has gotten into the habit of calling all the various types of switching power supplies "PWM". While the Darwin may not use simple pulse width modulation to vary the supply...

    Darwin...Is it really different?

    Using a 2.5ohm atty at 6V equates to 2.4A, which seems like it's within the battery spec. But it isn't. You never get something for nothing, and in the case of all PWM boost setups, you're getting higher voltage at the cost of higher current draw. The actual load on the battery for that setup...

    Darwin...Is it really different?

    Actually, you can. That's the whole point. The reason you use a microprocessor to control wattage is because wattage is the golden benchmark of performance for an atomizer. Voltage is arbitrary - 5V on a 2.5ohm atty and 5V on a 3.5ohm atty are completely different. But 8W on a 2.5ohm atty...

    Eastmall's Indulgence Review

    Two 18350s will definitely fit. I use them with a terminator from notcigs to make it an adjustable-voltage mod.

    Darwin...Is it really different?

    On any non-adjustable PV you can adjust the power by swapping out different batteries and atomizers - but nobody has any problem seeing the advantage in an adjustable-voltage mod. A mod like the Darwin which automatically varies the voltage to maintain a constant power setpoint is just as big a...

    Darwin...Is it really different?

    Thank god somebody finally got around to making a smart PWM buck mod. I started a project like this months ago, but got distracted/annoyed before I managed a fully functional prototype. I didn't anticipate what a pain in the .... microcontroller programming was, or how much programming and...

    Longest lasting 2.5ohm 510?

    I remember having some attys from Madvapes a while back that lasted a lot longer - I guess they were bauway. I just checked and they had 5 in stock, so I bought them. If these do work out, I hope MV keeps them in stock.

    Longest lasting 2.5ohm 510?

    3 ohms won't give me the wattage I need. I know a lot of people use standard 2.5ohm 510 attys at 5V, I'm just looking for suggestions on which brands hold up better.

    Longest lasting 2.5ohm 510?

    I've burned through 5 510 attys (2 joye, 3 boge) in less than 3 weeks. This is starting to annoy me. I need a 2.5ohm(ish) 510 that is reliably good for at least a couple weeks at 5V. Has anybody had good luck with a particular brand? I'm willing to pay extra for something that holds up.

    ProVari Variable Voltage Mod

    Sorry to bring this back up, but I see you never got a quantitative answer. You don't necessarily need an IMR battery, but you do need a battery that will safely and reliably provide the amps that the mod draws. The exact amp requirement varies based on a lot of variables, but here's the...
