Ok I need someone even geekier tha me for this

[ShannonA]

I tried google but I guess I'm not searching the right terms... I have an ac/usb adapter and it's got a sticker on it with all those great numbers I barely ever pay attention to... I'm wondering if anyone could tell me if any of those numbers indicate how many amps it is and pehaps which numbers to calculate by what to figure it out.

Wanting to find out if it'd be ok to use with a passthrough. To the best of my recollection it came with a touch screen cell phone that got dropped one too many times.

I need to slow down I'm always getting a typo in my title

There should be an ampere rating on there somewhere. However you need to post the numbers (just write down everything that's written on it) before we can tell you the answer!

Ok I will post them tomorrow both the lighting in my house and my eyesite are really bad. So I can read Courier Charger and that's it right now.

Googling a Courier Charger USB Plug shows it as 5.0V 500mA which is a little too light for good vaping. The mA should be at least 1500 - 2000 mA (translates to 1.5 - 2.0 A)

I adapted a D-Link Jta0302C Power Supply Ac Adapter 5V 3A with a USB connector for a full 3A.

If the available amperage is lower than you're trying to draw for a set resistance (however many ohms your atty / carto has and it don't change) than the voltage will drop.

As mentioned above, mA is milliamps (the amperage). 1000 mA = 1 amp. 500 mA is 1/2 amp.

It is fine to use this with a battery powered 3.x volt PT. It's the 5 volt PT's (no battery) that require at lest 2.0 amps (2000 mA). So, the answer to your question depends on the type of PT.

Thanks that answered it perfectly AND saved me from going crosseyed. For the PT I'm looking at right now it would work for the one I really want but can't get just yet it would not.

I use a 5.1 volt 2.2 amp power supply, for my homemade passthrough But this atty gets hot fast and I could easily burn it up if I'm not careful.

The Trick is to match the right atty with the right power supply so you get the best vape experience you can without getting the atty too hot with a high risk of burning it out - and with the best vapor which you get between 6 and 8 watts.

If you have a suitable power supply but an atty that can't handle the current, your best bet is to just buy an atty that is better match for that power: voltage, amps and Ohms. ( or use the chart below and buy a power supply and an atty just for the passthrough project))

You can get info on the best power to use with each type of atty from this chart and following pages that explains all the good bits:

For instance. My Atty is 2.0 ohms. I know this because these are it's specifications listed when I purchased it. Now the best vaping experience with lots of good vapor for most people is between 6 and 8 watts. If I take my finger and put it on the 2,0 ohms at the top, and go down to the numbers that represent the 6 to 8 watt range, then go Left, I can see that the ideal voltage for my atty is between 3.5 and 4.0. ( So I'm running a little high at 5.1 volts and have to be extra careful - I need a better atty to match the power)

It's made from a Riva 510 SE atty and I still use the batteries which are 3.7 volts for vaping away from home so my vaping experience is the most ideal - the atty and battery power is nicely matched.

Now lets do the reverse. You have a power supply that has a known voltage. On the left look down till you find that voltage. Then trace your finger across till you get to numbers that represent the 6 to 8 watt range. Now follow those numbers Up till you see the types of atty's you can use. Find the best one that matches your thread size ( 501, 901 etc) and you will know what type of atty to buy.

That's it This chart and info on these pages should help you understand it all and find the best matching power supply and atty for you.

Hey, if I am mistaken about any of this someone please correct me.. I just found this info last night but I'm pretty sure I understand it right.

...............Hey, if I am mistaken about any of this someone please correct me.. I just found this info last night but I'm pretty sure I understand it right.

I'm pretty sure you're on the right track here. I think it's why some folks are so happy with their vv mods. It allows them to dial in the best fit for their equipment and juice. An exception would be the duel coils, because they divide the current and spread the heat over a larger surface area, and they manage to provide more vapor at relatively cooler temperatures.

For me, a good juice example would be MLB. I really like it at low wattage, where a long slow draw produces decent vapor, but start hitting it with more wattage and it turns harsh and nasty real quick.

That's good info, but she was asking about matching a USB power supply to a Pass Through (PT) not atty to battery.... she needed to know about amps.

However, the chart is handy. It is also easy to go by wattage and use V * V / R for standard atties/carto vs battery voltage. I go for around 8 watts ( 5 volts, standard joye atomizers) so 5 * 5 / 3 = 8.333333. Easy. Don't have to carry a chart.

Ah. My mistake. I thought she was attempting to make a homemade pass through. I got that impression because I couldn't understand why she would already have a pass through that needed a power supply. I thought one came with the other when purchasing or the pass through's atty would be matched up to use the voltage from a computer usb.

Hehe no.... I'm not into all that mechanical stuff it goes beyond replacing computer components it's too involved for me. I'll leave that stuff to DH.
