Battery Pack Question With USB Passthru

[yvilla]

Houdini and Cell, so it's like I never posted??? What is this?

[CandyGirl]

i noticed that too yvilla. just rude.

[yvilla]

Could it be they think that because I'm a woman I don't know what I'm talking about, even though they are the ones that keep posting erroneous information?

[CandyGirl]

EXACTLY what i was thinking. what do we know about the testical aspects of these things. LOL

yvilla, I much appreciate your response and know that you are much more technically proficient than I am.

Sorry yvilla. Didn't mean to be rude. You quoted my post but said basically the same thing I said. That it needs to sense a battery for it to work. I would just like to hear from someone using a no battery usb passthru and a battery pack that work together and which battery pack it is. I guess its the APC one.

a PC USB socket is rated at 5 volts at .5 amps current... this equals 2.5 watts..

so a USB socket either isnt up to the job of properly powering an e cig or its being over loaded..


ps... one other thing... a simple lead connected to an ecig atomizer at one end and a PC usb socket at the other end has a resistor or something built into it.. this is to stop the e cig getting the full 5 volts from the USB socket.. without the resistor the USB socket would burn out and so would the e cig heater coil... something designed to be fed 3.5 volts should not be getting fed 5 volts..

Trog, I'm probably misinterpreting your two statements above but it seems on the one hand you are stating that a usb socket is not powerful enough to properly support an e-cig but on the other hand stating that a resistor is need to insure the usb socket doesn't burn out the e-cig. Also, why isn't a battery pack just a larger source of power for the e-cig than the batteries provided?

Houdini--I use Puresmoker's autoswitch passthough with no battery inline. The power source I bought is this one: USB 2 Battery Pack and Charger for iPod; iPhone 1G, 3G - eBay (item 250372127023 end time Mar-13-09 09:57:14 PDT)

And it is a BEAST--goes 3 days before you need a recharge with heavey vaping--hope that helps--Sun

Houdini, my point was that any mobile power pack (something meant to power devices) that has has at least 1000mA output will work. The APC, the one Sun just referred, to and many others. For example, I have both the APC and a Rocketfish "Portable Power Source" that both work, and I have both kinds of passthroughs as well.

But when Cell keeps using the term mAh (capacity) when he's really talking about mA or A (output), it does indeed get everyone all confused.

Thanks yvilla. I got it all straight now. The packaging of these things can be deceptive though. The Duracell package says "The Instant Power Charger simultaneously powers and charges USB-compatible...." then it lists a bunch of stuff.
Anyway, I will probably wait to get anything until after I get my ScrewDriver. I'm thinking I won't need an extra battery pack and may not even use my 901 much after trying the SD. It should be here in the next day or two.
