Pass Through Wall Plug

[Cartomeister]

I made a youtube vid on how to use a pass through with a wall plug, not everyone has a laptop to bring with them when they stay in a hotel or cruise ship. You know the iphone wall adapter. that works with a vapornine.com pass through and vapor4life.com pass through. I have been testing it for a week and I have not blown my face off yet. Proceed at your own risk. I say it works. You can see on my youtube that it works. Youtube name Cartomeister. I suck at making youtubes but I just want to get the word out so they're good enough for that.

Not sure about the adapter you are using but I've heard that only 2 amp adapter will work with most USB passthroughs. I tried my 5v PT on several USB adapter with no luck. Just thought you might mention this in your video.

iphone adapters are pretty strong, its a small white plug with a usb port on it. It charges an iphone so I think you might want to give that a try but 5v sounds sick and I have no 5v battery to test it. I will get one though and find something that works with, or mod one maybe. I am mechanically inclined so I might take a whack at it.

mine are deltaco USB-AC2 with output 5V MAX 1AMP and it work like a champ.

It will vary depending on how your passthrough works and the reistance of the atomizer.

Some passthroughs step-down the incoming voltage -- just today I read a post where a PT actually output 3.7V.

The current needed = voltage/resistance-of-atomizer. If your atomizer is 3.2 ohms, and your PT is actually passing 3.7V, then the power supply needs to drive 3.7/3.2, or a bit under 1.2 Amps (1200 mA). This may well be workable, even for a nominal 1A max output supply -- there's engineering margin in specified output.

A 2A rated output gives much better comfort/margin. Even if the PT is truly passing the 5V, and your atomizer is only 2.5 ohms, then 5/2.5 = 2 Amps, in other words you're within the rated power of the supply, not stretching into its margin.

The above is why 2A is generally recommended -- it covers the great majority of users safely, without risk of over-driving the supply.

There are 2 different kinds of PTs. The ones with a battery box spliced into the wire are "indirect". They operate off of that battery, usually 3.7 Volts. A regular USB plug putting out 5V @ around 500 mA, or 1/2 of an Amp, is sufficient to recharge the battery (and that's ALL it does).

A "direct" PT has no in-line battery. It operates at whatever Voltage and Amperage of the device you plug it into. An iPhone wall wart puts out 5V @ 1A (or 1,000 mA). It is enough to power some attys, but not all of them. It also costs about twice as much as a 5V wall wart that puts out 2 Amps, and you will notice a drastic improvement in performance if you get one of those.

You don't want to recharge a Li-Ion battery @ 2 Amps, it's rough on the battery and will make them die a lot sooner. You can cut the battery box out of an indirect PT and splice the cord back together to make it into a direct PT. You can splice a different box in, and make it hold a bigger battery, or even 2 batteries.
