usb passthru w/10440 inline 320mah battery for 510 atty

[KEITH97M3]

I got a 510 usb passthru with inline 10440 320mah battery from liberty-flights a few weeks ago and I noticed that it produces a lot more vapor when it is not plugged in (once the battery is fully charged).
I tested the voltage with it plugged in and it is 3.95 volts, unplugged the voltage is 3.94 which makes practically no difference. (voltage tested at contacts where atty screws in)
Can anyone figure out why the vapor and throat hit almost doubles with it unplugged ? At first I thought I was just imagining this, but after many tests I found my theory to be true. Since the product came with no instructions, I am not sure if I was supposed to just plug it in to charge battery then unplug it to use or what. I am not complaining about this product as I think it works awesome and was well worth the 12.59 I paid for it. I just want to figure out why it works the way it does.

Well.... Long story short, when its plugged in & the batt is in some of the power goes into the batt. So batt acts as sort of "resistor" and the wattage on the output falls....

Thanks mitrich, sounds plausible to me. I thought it might work like a car battery, you know when the car is not running it only has 12.5 volts but when its running and the alternator is charging then voltage goes up to 14.6 to charge the battery and run the car with accessories. My initial suspicions was that maybe when it was plugged in, the voltage was higher making the atomiser burn too hot thus evaporating most of the liquid. I think your explaination is more likely though. Thanks for the reply. Being an ex 3 pack a day smoker, I am still craving more throat hit and vapor and am still trying to figure out what works best. I experimented with Njoys and other crappy ecigs over a year ago but gave up because they were so poorly made that the frustration sent me right back to smoking analogs. Only now do I have a decent 510 and so far i've been tobacco free for a little over a month. I still want to find something that puts out that warm hit to the throat with tons of vapor. I still crave a cig right after eating a good meal and the 510 is great but doesn't give me the same satisfying feeling as an analog. Seeing how new mods keep coming out, I think i'm going to wait till I see something super awesome that can satisfy me for at least 8 hours of heavy vaping without recharging batts or refilling carts. Being a painter, stopping work to change batts or refill carts gets kind of tiresome. Hopefully soon someone will invent a cart that holds 5ml of liquid and a batt that can go for days. Wishfull thinking but ya never know.

Sounds like you need a mod with an 18650 battery and a LR 510 Atty!

HELL YEA! my Woodie is by far my favorite mod as well~~~~

That doesn't make sense. At ECF a member tested loaded voltages and found the Joye pseudo-PT to be running at about 3.2V (under load), a touch more than the Joye batt's 3.1V. I assumed he was testing it plugged in.

Ok, I retested voltages under load. The only place I can take those measurements is at the inline battery.
Plugged in no load=4.1 volts
Plugged in under load for 5 seconds=3.8-3.9 volts.(starts off at 3.9 after pressing button then drops to 3.8 after holding for 5 seconds)

Unplugged fully charged no load=3.95-4.04 volts (reason for this fluctuation is because every time you run the test back to back, the voltage gets lower and lower.1st test was 4.04, 2nd was 3.95. Levels off at 3.95 for a while after that then drops gradually after constant use)
Unplugged under load=3.7-3.8 volts ( starts off at 3.8 after pressing button but drops to 3.7 after holding for 5 seconds)

Did this test repeatedly at least 5 times each, wrote down data and took the median measurements. I forgot to add that the atomiser has 2.7 ohms and I have tested this with 2 separate identical joye 510 attys. Although I am not an electrician, I have 2 years highschool electronics and 2 years of tech school electronics, also was an auto mechanic for over 15 years so I do know the basics. I think the most accurate place to take these measurements (watts and amps) would be at the atomiser but with my skill level and equipment, that would be close to impossible to do.

I'm gonna go with mitrich's theory for now so I can relax and enjoy my day off I've been stumped by this for weeks

Ps. thank you also to capevette for his interesting mod video

You guys would laugh if you seen the crazy inventions I have made just to vape while at work painting a house. I've taped my ecig to my shirt, tied it with a string and hung it around my neck, used the passthru and tied it around my neck, attached a rubber tube to the cart so I could hold it in my teeth etc. I will do just about anything so I can still vape while rolling a ceiling

That's not the real vaping load. All 3.7v batts are basically the same. Joye products (including the eGo) are voltage regulated at the atty. The ECF test was done with the voltages actually available after the switch/electronics.

Back to my original question and even I agree it doesn't make sense. How can you explain the huge difference in vapor and throat hit ? At least twice as much with the unit unplugged. I'm still plugging and unplugging the usb while testing all day today. No matter what I do, the vape is way better unplugged at the supposed lower voltage. The usb port must have power if it can charge the battery quickly and as far as I know, power from the usb port on a dell computer is constant when the computer is on.

I hope someone else with the same passthru can validate this, pretty sure other forum members have one.

Do you have something else to plug it into? Could simply be it's defective as I don't recall others having reported a similar situation.
