Best 5 Volt 510 Pass Thru?

[Madshock]

You are wrong. 1A will not fire a Joye (2.2Ω). Using Ohm's Law we get 2.2V. A Joye atty will not fire at 2.2V which is not even close to the 3.2V you erroneously stated. 3.2V would require at least 1.5A (50% more). To get the 11 watts you mention you'll need about 2.2A to the atty.

Yup i admit on the erroneous figure of 3.2 with 1amp. that would effectively mean the resistance is at 3.2 for it to be that figure! not too sure what went on in my head when i was thinking about this last nite. Apologies for the misleading info.

In Ohms law, if the voltage is 5v, and the Atty is 2.5 Ohm ( My 510 atty is actually at 2.5). Shouldn't the current be 5/2.5 which is 2 A? This is the reason why i believe 5v 2A is sufficient tp be hitting the 10watts mark. however, ranges from atties differ. I think I've seen figures from 2.2-2.5Ohm for regular atties (Not 100% sure here)

So in the end, if your atty is below 2.5, you will not be effectively doing 5v vaping because of the 2A Max of the wall plug.

I believe this debate started because i put too much emphasis on the voltage. Neglecting the other relativities.

Unloaded volts mean nothing. 5V@ 50mA will still read as 5V with no load. If you want 5V, while vaping (loaded), with a Joye 510 you need 5V @ 2.3A.... period. To call a PT that doesn't come with a power supply, that can supply the correct current, 5V is disingenuous and misleading.

Tell that to the creators! There is no end to the market saying they have 5V PT but does not give the right watts ratings if you do not have the right power supply! They should have a disclaimer for this..

And you made me realized 1 important thing which i didnt gave much thought on because i chucked my PT into my stash after having my mods.
Unless there is a USB Wall plug with more then 2A max of a rating. PT should never be able to hit 5V vaping for those having atties rating below 2.5ohms this moment? so far I do not think I've seen any USB wall plugs above 2A. Not too sure about wall warts tho, nv looked at them.

Cut and hardwire, or replace some connectors.

Or:

PROVANTAGE: Availability of SonicWALL Power Supply 5V-2.4A 100-240V (N. America) By SonicWALL

Unless you need the 'bling' factor using the top 3A power supply you can make a complete PT for about $16 that will provide a true 5V for any standard atty. The switching power supply is also efficient and will not have to be running at max output to keep up.

It's a very simple and satisfying first project and only needs 4 solder points. Note you don't have to worry about the polarity of the wires, the atty doesn't care about positive or negative.

The parts at MadVapes:

- 2xAA box/no switch

- 5A horn switch

- sealed 510 connector

Will run about $5.50.

It will easily outperform this model, that will not in fact provide 4.9V with a Joye atty as claimed.

THE VP-PT (USB PASS THRU)

Do note many who think they are vaping at 5V with their current USB devices will be surprised at what true 5V vaping is with this home built combo. Go easy on the button and keep that atty wet.

wish i had the tools to pull that off (drilling holes in the box/soldering, etc) as well as any sort of technical inclination, cause that looks like it'd be a great pt, especially with that 5v 3A power supply.

 

[WillyB]

Well the hardest part is soldering the atty connector, the rest is a cakewalk.

 

[tardcore]

also, just want to make sure i'm 'getting it'. if i have a 510 atty that's around 3 or so ohms, what kind of amperage do i need to really be 'vaping at 5 volts'?

E = I * R

5 = I * 3

I = 5 / 3 = 1.7 amps


Now the question is what happens if your power supply isn't rated for enough amps. That depends on the power supply. You might damage it, it might shut down, or it might just let its output voltage sag to whatever it is able to deliver.

Always use an power supply amp rating that is MORE than you intend to draw.

thanks! i'm using one of these:

USB Dual Power Adapter

that site says 2A when i'm only using 1 port, so i should be good. regardless, i'm still interested in maybe building one of those passthroughs...might just need to learn how to solder, i guess

Those are OK, but with mine (same one) using a Joye 510 (2.2Ω) with a rather long USB cable I'm actually getting about 1800mA to the atty for 3.9 vaping (loaded) volts.

 

[tardcore]

actually, i just had another thought. since i've already got my usb PT (510 w/ no batt inline), couldn't i just take a power adapter (like that 5v 3A one linked) and hook it up to a female usb connector? seems like i could save myself some time/money...hmm....like, for example, one end of a usb extension cable, so the usb connection is already soldered, i'd just have to hook up the power wires from the adapter to the wire coming out of the usb connector...right? technically wouldn't even need solder, could just use some teeny little wire nuts?

 

[WillyB]

Sure. Twist 'em, tape 'em, get some crimp on .... splices.

 

[tardcore]

kind of a necro, but it still relates to this thread: if i hook up a 5v 3A power supply to my no batt PT (like this from madvapes: MadVapes 5 Volt 510 Manual USB Passthrough), will the switch be able to handle it? i finally got around to buying myself a power supply to try out 5v, and this occurred to me. i just submitted a ticket to madvapes to ask, but i wondered if anyone here might know?

My computer has a high-quality 600w PSU (its a gaming desktop), and it has no problems delivering the 5V at the battery end (no atty attached - tested w multimeter), using a PT like the one linked in the above post.

The USB spec calls for 5V. Even a computer with a $15 PSU will output 5V, no atty attached .

Good to know. But a powerful PSU will do much better amperage-wise as opposed to cheap PSUs, dont you think?

 

[Broseybrose]

Is there a way to test the volts youre getting with a multimeter with the atty attached? If so, where do i stick the test points?

Or is it a matter of testing the res of the atty and then doing some math?

 

[thestoppableforce]

i made a pt that runs off a 5.1v wall wart at 2 amps its identical to that picture a page or 2 back, my question involves what ohm range atty i should be using for optimum performance. also i have a usb hub 4 port thats powered by a wall wort, it says it's 5v 2.6 amp not sure if it changes with the amount of plugs in use, i don't use it but i saw someone saying they werent sure about usb plugs being rated over 2 amp, its a belkin i can get a link if anyone is interested.
