Passthrough question & atty cleaning hint

[doris]

Back again for more help.
I've been vaping Kanger Tech EVOD 2 with dual bottom coils & I'm satisfied--more or less. Since I do most of my vaping at my pc or sitting near a power supply, I thought I could save on batteries by using a pass through. Guess I didn't understand clearly how a pass through with a battery actually works until I bought 2 kanger evod passthrough batteries. I thought the pass through would skip the battery entirely. I think what I want is something like this:
$5.30 VV Variable Voltage Passthrough - chromed brass / silver / 1.2m at FastTech - Worldwide Free Shipping

No battery but also no info on whether I can use this with my current tanks & attys. Have a ticket in with Fasttech but still waiting for a reply. Anyone know? Or any other suggestions? I'd be willing to change tanks & attys if it's worth it.

Now for cleaning the evod bdc atty. Even though I don't vape dark liquids I was having a problem getting a week from an atty. I tried everything I could find about cleaning: soaking, dry burning, & boiling. Dry burning worked the best but still not great. A while ago in frustration, I took a toothpick & gently prodded through the bottom & the top of the atty. The toothpick came out coated with black gunk--I've also used a long straight pin. I then flushed hot water through the atty & was stunned at the amount of black ash that came out. I now use an old plastic pill bottle filled with hot water. Stick in the atty, lid & shake vigourously. If it seems worth it, I'll follow with a dry burn, more prodding & flushing. Tada! I'm getting over 2 wks on an atty. I now only replace when the atty no longer heats. I keep thinking that one of these days I'll break a coil but not yet.

TIA
Doris

Yes those passthroughs are ok for the evod size coils.
That's what I started with.

Just like regular ego type batteries, however, could get centerpin issues.
If you are using the evod type clearo with the ego thread you will get less centerpin problems.

To reuse coils, pull the top spire off, and dyburn the coil; you should see your silica wick go from black to white as the stuff is burnt off.

Pass through is going to be pretty limited with what it can use when it is bypassing the battery entirely. If you are using a typical USB port on a computer, it is only going to give you 500 milliamps of current. That current will be at 5 volts. That means it will be giving you 2.5 watts. Even if you are using a 1 amp charger to power it, you are still limited to 5 watts.

A passthrough with a battery uses the battery to fire the coil and cuts off charging while you are taking a hit.

I use a homemade 5v passthrough as my regular vaping device. I'm using a 5v 4 amp AC adapter as a power supply. The lowest resistance coil I can use is around 1.25 ohms. I'm using a 1.5 ohm coil which comes to about 17 watts at 5v.

As speedy_r6 said a normal PC USB port is only 500 milliamps (.5 amps) so you can see the limitations. Some newer PCs have USB 3.0 which put out 900 ma (.9 a). You would need to stay in the 1.8-2 ohm range for that fasttech one to work properly.

It is perfectly possible to build a plug-in mod using a 100 or 200 watt variable voltage power supply. Given the purpose is to fire an induction coil, it wouldn't even care if it was AC or DC. It would look like a box to hold the power supply, with a knob on top to regulate the voltage, connected to a wand by a cord, with said wand having a switch to fire the power supply and a 510 connector to hold a topper. You'd have to build it, though; I don't know of one for sale. Say! That's an idea...

I bought a pair of cheap FT pass-throughs. Neither worked.

FT repaid me the money and we never talked of it again.

(until now...)

If you build it, commercially, I'll buy it!

I guess I knew it was too good to be true. Back to plan A which is to find the "best buy" battery.
