@modifiedamerican - There is an easy, very cheap way to solve
both your carrying concerns for your eGo battery and CE4...
and adding a Kanger Aerotank Mini to your gear!
MisterEliquid is having a 50% off all clearance items sale. He has the following on his website for dirt cheap, and his S/H is right around $3.00! You don't need any discount code either, because the discount is taken off in your Shopping Cart.
I ordered some of the cases below a few months ago, and they're very tiny, but easily fit an eGo battery, a small tank, and a small bottle of eliquid in it. I just ordered more of the Aerotank Mini tanks below yesterday, along with some drip tips for 50 cents each, and some of the Aspire CF Mods below for just $3.47 each.
Small eGo Vaping Case - 49 cents - 50% = 25 cents each
Kanger | AeroTank Mini by KangerTech - Just $2.50 each after the discount! That's a steal for them! Coils are readily available for them, too! Each boxed tank has the whole tank in it as shown, and...even comes with 1 1.5 ohm coil already in the tank plus 1 spare coil, and a stainless steel replacement tank for the glass one, if you want to be sure you won't break the glass one it comes with. Those 2 coils would last you at least 2 weeks of average vaping most likely. Would be long enough to allow you to order more coils. (See info. at the bottom of post for them.)
Aspire CF Mod - These would be good to use when you're ready to move up from your eGo batteries. They're alittle bigger around than an eGo, but are the same tube shape/form. They take a replaceable 18650 battery, that's rechargeable with a charger. At $3.47 each after the discount...they're also an extremely good deal! You would need what's called an eGo/510 adapter to use the Aerotank Mini on it, but the adapters are really cheap, too (about $2 at most).
Even if you got just (2) of the little carry cases + (2) of the Aerotank Minis right now...you could spend
less than $9 total including S/H and be set for vaping at least a month with the coils they
come with already. (Personally though,
I'd go ahead and grab 2 of the Aspire CF Mods and just stash them away until you're
ready to move up from your eGo...even if you don't want to right now. At
that price...they're worth stashing them now.)
A good place to get the coils is at DesertVapes.com. She sells them at a very good price for the 5pack, and has inexpensive S/H by First Class Mail. If you'll use the coupon code "1storder10" for your first order from her...you'll get a 10% discount, too!
Here's the correct coils for the Aerotank Mini. I'd personally choose either the 1.5ohm or the 1.8ohm to be most like what you're used to with your CE4.
