I just don't get it

[Grumpysanta]

USB1 on a laptop usually 100mA, on a desktop pc 500mA
USB2 on a laptop or desktop up to 1500mA

result USB1 sometimes does not give enough current to drive a USB e-cig

thats why I asked. Usually USB2 compatible devices will be labeled as such so if there is no label suggesting USB2 then that device may be USB1 only.

It's not laid in stone, just something to be aware of.

Pete, I seem to think you had the same charger (I think you showed a pic of it one time). I got mine off ebay. I have 4 regular household batteries in it. Are they the right kind? If so, I wonder why it wouldn't work. If not, I better go shoppin'!

[ZambucaLu]

Grumpy, my laptop is probably a usb2. As for the other adapters, I don't know because they don't say. It's funny though that when I have seen those adapters on other sites, the ones I got LOOK the same (actually look just like the janty spare parts). But they must be different....stronger. Well, thanks for your help.

And this might explain why they didn't work on my laptop at work. That is older than dirt....probably a usb1!

Yes that's the one. If you are only using non rechargeable AA cells, it's unlikely to work for very long, they can't supply the current. You need to get 4 AA NiMH rechargeable cells and a charger. Look for a rating of 2400 mAh or greater. Now your in the US so I can't suggest many shops, are Radio Shack still on the go?

this is the sort of batteries you need:-
Amazon.com: Powerex AA 2700mAh Rechargeable NiMH Batteries w/holder- 4 Batteries Per Pack: Electronics

and the charger
Amazon.com: Smart Charger for NiMH/ NiCd Battery - AA, AAA by Vanson: Sports & Outdoors

These are just to give you an idea of what you need, they will be a lot cheaper on ebay!

OMG! That makes a lot of sense to me. Regular batteries probably just won't cut it. If rechargeable batteries work, it will be worth it!

Maybe dealextreme has 'em...lol.

Thanks so much for the info. I mean....how else would I have known that? And if it worked for you, it should work for me. I'll tell ya....I'm learning something new every day on this forum. This whole thing definitely is a learning curve!

Thanks for your help too.

a USB port is rated at 500 mah an e cig can draw 1000 mah..

Sambuca, DX does have the NiMh AA batteries. So does Walmart and any drugstore in the US. It is the rechargeable battery they sell everywhere - you would have to search to find another rechargeable. The important part is to make sure they provide 2400 mAh. Most are rated much less than that. I know Duracell and Energizer both make them this high. I did find the best deals though on ebay.

[ZambucaLu]

Yes, nic, it is the 2400 mah that's stalling me. I did look on ebay and found 2 options of interest. The funny thing is, I was just thinking how much I hate charging bats for my penstyle and now I have to go buy a rechargeable bats and a charger, so I'll still be swapping bats!

If I didn't laugh, I'd cry

they dont have to provide 2400 mah.. 2000 mah or even 1800 mah would do they will still provide the desire current just for a slightly shorter run time..

assuming we are talking about powering an e cig which normally only powered by a 130 mah battery..
