feeding five volts straight from the USB socket to the e cig atomizer will wreck the PC..
Here Trog100 is not right I think. The USB 2.0 specification clearly states, that USB ports complying with it shall have overcurrent protection and shall withstand short-circuit for unlimited time. It is allowed for the port to shutdown its output power under overload conditions, or even to require a reset to resume normal operation - these are up to design - , but no damage to the port is allowed by the specification.

Consequence - in my opinion - is that if anyone's USB port is fried by an e-cig, or a short-circuit, then that port did not fully comply with the USB 2.0 specification, and so the manufacturer is liable for the damage..

This might not apply to USB ports complying with the old USB 1 specification, what I do not know at all. Anyway, the USB 1.0 port in my old desktop was not fried by the USB mod either, it only seemed to provide much lower current (current limiter inside).

I have a USB passthrough coming for and with a Classic penstyle I ordered from Steve. I was planning on using it with my computer but am now a little worried. I don't have a laptop. Just your basic tower computer. Yes I'm electronically challenged. But will the USB passthrough damage my computer?

Idahojo You Should Be Fine! ;)

Thought I might throw this in the mix from another thread....

The two companies were once one. I marked every battery I returned to s51 and got a couple of them back as replacements. So far haven't heard back from them about this.

At one point they shipped what they called "new" batteries - that was in Jan. They weren't. They haven't had anything new since and claimed they "bought Loongtotem". LT doesn't have a factory to buy. They don't do any of their own production. They are oversold without a plan and vicious competition.

After 3 kits returned to the nasty guys at the Freehold mall they refused to exchange, wouldn't sell me carts (I don't think they had any anyway) and told me, loud enough for the whole mall to hear to GFMS. S51 says to go back to him... after that incident s51 sent me to esmoke who gave me 2 working batts and took my crap ones back. esmoke told me that almost every other s51b battery since the "new batteries" were coming back and about 1 in every 4 chargers.

I started to open the batteries and found at least 4 different variations and 2 different chargers trying them with e-cig chargers and batteries but no joy there. The only similarity was that they all screwed into each others chargers but that's it. I started to test them with my multimeter. While they all put out around 3.5 volts the mah was widely variable from less than 170 mah to over 400 mah! Some of the small batteries were more powerful than the big ones! There's too much discrepancy inside of what looks the same outside. Same for e-cig. I can tell you that LT does not make batteries.

What's inside those 9mm diameter tubes is not from the same place even though the outside seems identical. Some say "Everready" and there are at least 4 different types of batteries inside and 2 or 3 different Panasonic clone transducers.

Glad I paid with PayPal because I held my money back and already got back some of what was paid to s51 and everything I paid to LT.

Last night I put together a battery from 3 separate ones using the best parts from each and with the right grey cap on the front - smaller slits (those were all different too!) I got it charged and it's really good, i would say almost perfect. It has no outside branding and all the carts work on it. So far so good.

I suppose I should get a life but my curiosity got the best of me and at least I was able to get most of my money back - albeit through PayPal disputes and I got a favorite battery now!

Put me more than a little gunshy of buying s51, can't get LT anymore except through them and e-cig shipping is also higher than LT used to be.

I hope my batteries last because I just have enough parts to probably get one more good one out of them. Now I have 4 good ones from esmoke, 1 good one made up from a hybrid LT outside e-cig inside (short version) and 1 good one from a LT inside and e-cig outside (long one). The one with the e-cig inside only works off their charger and not the LT or s51 chargers so I had to mark that with a CD marker to know which charger it goes in. That's not a problem with my USB car charger, either the e-cig USB or s51 USB chargers work off that in the USB port. That's good because i do a good two to three hours in my car (with non smoking co-workers).

I'll take some pics of all the battery innards if you guys want.

not sure if i am posting in the correct place .....but.........i took my usb 901 charger thingy to work & plugged it - all was good for about 1 minute - i smelled smoke and was thinking who in the heck is smoking in the office...no that is something burning in the office ...holy crap that is MY computer smoking!!! yikes...
i quickly pulled that sucker out and with all the nerve i could muster up told my boss that hmmm ...excuse me...yeah...well.... i think my e-cigarette toasted my 'puter.....(the usb plug totally overheated and crashed the whole dang computer) .....needless to say my boss was less than happy with me ....
took it to computer wiz & he said the usb charger was not compatible with my usb port...something to do with new port vs old port.... ....so just f/y/i if you have an old computer don't use the usb charger....
or crash, boom, bang, fire in the hole....
the computer was a lost cause
however my e-cig & charger survived and thankfully i am still employed ...
has anyone heard of such a thing? or just my bad luck?

depends on your charger. If your battery charger charges at 500ma, to charge an 1800mah battery you would need to charge it for 3 1/2 hours (1800/500). If it charges at 100ma you'd need to put it on for 18 hours (1800/100). Chargers that were made for lower capacity batteries probably charge at much lower rates like 100ma, which isn't really powerful enough to charge an 1800ma battery without it taking forever. Find a battery charger that charges at 500ma to 1000ma (1 Amp) and just apply the same charging method. If you're charging a 1800mah battery with a 1 amp charger you'll only need to put it on charge for about 1.5 hours.

I use a standard trustfire charger for my ecig modded batteries. It charges at 500ma. My battery capacity is 2500Mah. That measn it takes 5 hours to charge fully if the battery has been drained. I normally don't run this one dead just because it lasts forever, so every now and then I'll put it on charge for 3-4 hours then it's good to go.

I love this forum, my questions get answered without ever being asked(by me):rolleyes:

I've got an m401 style from mirage and I was under the assumption that all the batteries used for these ecigs were li-ion. I emailed mirage to get the specs for the battery and he informed me that it was a 3.7v 150mah battery.

This would mean that it is not a li-ion battery, but a li-po battery. I confirmed this with an r/c hobby charger. It will not charge the battery when I try to use the li-ion setting as it gives me a voltage error. This is because li-ion batteries are 3.6v per cell while li-po batteries are 3.7v per cell.

I'm not sure about any of the other batteries out there, but the one I've got I'm pretty sure is a li-po battery and not a li-ion battery. I've also emailed intellicig about the evo as I have one of those in the mail and I can post the specs when I get them.

I'm no expert on the subject, just goin by my experiences so far.

dont know about that, i received my dse701 ecigar and it came with 2 batteries, a 3.6v 360 mah battery and a 3.7v 360mah battery, why would they send 2 different kinds and 1 charger that would only work for one of em? (the charger works for both of em)

Good point, it would not make sense to send two kinds of battery. How are you finding the voltage of each battery? I was going off of a table that came with the instructions for my charger. After doing some more reading, it looks like the nominal voltage for liion can be 3.6-3.7 volts while lipo sticks at 3.7v. I may have to give it another shot on the liion setting and see if it works.
