a E-CIG Passthrough question? please help.

[onefive]

Hi, I would like to buy a USB passthrough and I had some questions:

1, I heard the USB passthrough only worked with a USB output 1000MA and they said it worked on the laptop USB output but from what I know that laptop USB output is only 500MA so will it work on the laptop?

2, If it work on laptop USB 500MA output, than I also have a two AA 1.2V batteries charger that has a USB output of 500MA, can I use this charger and put two AA 1.2V rechargeable batteries to make the passthrough work?

3, If I can not use the two AA 1.2V batteries in this output 500MA charger , can I just put two 14500 3.7V in this 500MA output Charger and make it work?

can any expert hear help me out, thanks.

If your passthrough has a battery in it you can run it an charge it on the PC if it does not have a battery you will need another 2amp power source it will tax your computer too much. 2 1.2v batteries will only give you 2.4v for a very short time, that will not drive a PV 3 or 4 1.2v batteries will drive a PV and one 14500 will drive a PV two will be 7.2V you would need a high voltage atomizer for that.

Is your passthru a 5v? I have read on here that some people have been burning up their USB ports with the 5v.

DON'T MIX BATTERY/CHARGER TYPES. Li Ion batteries need Li Ion battery chargers. Make sure you know what batteries go with what chargers (look on the backs of the chargers and read the batteries).

3.7v passthroughs have a inline battery, you can run them on a computers USB port. What's really happening is the USB is charging the battery and you're vaping off of the batteries power.

If it's a 5v passthrough you'll need another power source as the amperage drain is to high on those. Yes it may work but it does have the potential to overload and damage your computer and even if it does work you likely won't be getting a full 5v vape from it. For 5v you'll need a source that provides 2amp or over output such as this one which also gives you the ability to use it anywhere there's a ac outlet.

2 amp AC to USB Adapter, ideal for Passthroughs

Wow, Thank you all for the help, I don't even know there are 2 kind of passthrough (5V and 3.7V)!
The charger I have it's a emergency charger, it takes two AA 1.2 batteries but it also fit two 14500 3.7V batteries because they are the same size, this charger don't charge the batteries but it use the batteries you put in it to charge any electronic with a USB port like ipod, celphones....ect and it said it has a output of 500MA. so can this charger charge the passthrough (5V or 3.7V) if I put two 14500 3.7V batteries in it?

I would not put 14500 Li-Ion batteries in anything that wasn't specified to take 14500 Li-Ion Batteries. No I would not do it under any circumstances. Just because they are the same size as AA doesn't mean they share anything else, different chemestry, etc.

If it's a 3.7v pass through it should work fine on your computer. If it's a 5v pass through It'll work fine with the $7 adapter I linked above, small price to pay. jmo

My bad. I thought it was a battery charger, not a battery-driven-other-stuff-charger. lol.

500 ma is not enough for a 5v pt. It is enough for a 3.7 v pt... BUT.... the 2 x 3.7 volt batteries may fry it... also, you need the proper voltage specs as input to the pt. The PT is probably expecting 5 volts.

The PTs should either come with a bundle that has a charger, or you should order the proper charger/adapter. You can get car adapters too.

You don't charge a battery-less 5v pt anyway. So, the 3.7 volt battery driven PT will work with your computer. The 5 v batery-less PT will need that 2.0 amp AC adapter. IDK where the other charger even needs to come in, but if you use it, it must meet specs. USB spec is 5 volts. And it should have... (guess)_.......450 mA output.

If you take a portable battery back, plug in a 3.7 volt PT you get a portable PT. If you wave a magic wand over it and shrink the cord to zero length, you get a 3.7 volt mod (battery + atty connector "box").

If the same is done with a 5v PT and high-amp 5v USB battery pack, you get a 5v box mod.

So, in general, mods are for running around with portable batteries. 5v PTs are for being on a leash, with a constant power supply (Computer, AC wall plug, car power) depending on device. 3.7 v PTs are charge-n-go type of things anyway since they have a built in battery.

Of course, there are exceptions, and some 5v mods have built-in chargers with usb "PT" type connectivity. lol.

EDIT: I looked at the pics.
So, bottom line is that the charger MAY work with 3.7 v PT for a bit of a charge using 2 standard AA batteries (not the Li Ion 3.7s) since it outputs 5v 500 ma. Also, it states that it is for an i<whatever> so sometimes they have "smarts" in them that only works with those devices since they communicate <-->. I'd be inclined to avoid it.

What's the motivation to use it? I'd just get a car adapter for emergencies. That charger definitely won't do for the 5v stuff, and the 3.7 volt PTs already have a battery.

Of course, you could just get a box mod with a separate li ion charger and stack of batteries and swap em out.

It's unfortunate and not nearly as cool and convenient but be safe...don't use your computer USB port to power it. Especially a laptop. Buy the 5 dollar wall plug.

Passthroughs vape great you'll love it.

500 ma is not enough for a 5v pt. It is enough for a 3.7 v pt... BUT.... the 2 x 3.7 volt batteries may fry it... also, you need the proper voltage specs as input to the pt. You keep leaving the voltage out of your postings, and only quoting mA. The PT is probably expecting 5 volts.

So, bottom line is that the charger MAY work with 3.7 v PT for a bit of a charge using 2 standard AA batteries (not the Li Ion 3.7s) since it outputs 5v 500 ma. But it may not fully charge it. Also, it states that it is for an i<whatever> so sometimes they have "smarts" in them that only works with those devices since they communicate <-->. I'd be inclined to avoid it.

Hi, This charger takes two AA 1.2V batteries and can produce output 5V 500MA, so you mean it will not power up the 5V passthrough but can power up 3.7V passthrough?

Yes, I was wondering if I can use this charger as a portable device because I have so many AA rechargeable batteries.

I was also wondering if there has any no-cord USB passthrough and I can just stick the passthrough in this charger's USB port as a mod when I go out, and when I come home I just stick this USB passthrough on a USB extension, that would be perfect

 

[AttyPops]

I edited a bit. See above.

It may work. IDK.

A no-cord 3.7 v PT IS a 3.7 v mod. lol. Just get a 3.7 v mod. Some probably have built-in chargers. Then, you don't have to get hung-up on the "PT" concept. That box doesn't have enough amps for 5v.

So, it might work... if you can get past the i<whatever> issues, if any. It may just "blink" at you... like saying "what the heck did you try to plug into me? That's not an i<whatever>!" and not work. IDK.

Not to endorse any particular vendor but as examples.
I have a 3.7v pass through from Totaly Wicked that works very well and charges from any usb port. It is not very travel friendly because it has about 4ft of wire and a battery box attached to it. I mainly use it at the computer. A friend has an ego pass through from Got Vapes that runs at 3.7v when plugged in to the usb and when he needs to go somewhere he unplugs the cord from it and it runs at 3.2v like most of the ego type units. there are other similar units out there that are safe to use with all devices with usb ports. If you get a 5v unit you will defiantly need to get a 2 amp wall adaptor to be safe.

P.S. As a side note

1) The standard NiMH batteries don't hold a charge very long for some reason. They have hybrids out now that are better. However, if you sitting on a poop-load of NiMH batteries, there is:

2) Go to the modder's section and research "The Puck" mod. It uses NiMH batteries, rather that Li Ion. 4 batteries, 4.8 volt mod. That eliminates the whole emergency-charger issue... just use the batteries directly! You'll need proper ohm atties/cartos for 4.8 volts. One less thing to carry around, since you can't charge em with that box anyway. IDK if it was AA or AAA (might be AAA) but that shouldn't matter. Just get the right size box for your batteries, I would think.
