Quite a few options for you...
Note, if you have auto batteries be very careful not to drip too much!!! The
juice can run down into the battery switch and gum it up pretty bad...possibly even short the battery.
1. Carefully pull the filling out of one of your cartos. If it is a horizontal coil type carto, you can carefully pull out the center tube as well...if it's a vertical coil or you aren't sure just leave that center tube in there. If you have a drip tip, great, but you can also tail-pipe it.
A. If you have a auto batteries...just drip like 3 drops in the tiny hole at the battery end of your carto...wait a moment and let it go in the hole. Wipe it good...treads and all...screw it on the battery, then vape. Should get 5 to 10 good puffs from that at least.
B. If you have manual batteries, you can just drip right in from the top all you like.
2. 901 atomizers fit on your batteries. Drip a couple of drops on the atty bridge, then snap on a drip tip (or put the cart on without any filler) and vape. Again, if you have auto batteries, be careful and don't put too many drops in the thing and flood it.
3. You can also use 510 (or other attys) with a 808/901 to 510 adapter and drip on the bridge as described with the 901 atty above.
4. Get a pack of CE2 cartomizers. Don't fill it up with juice...just drip one drop on the coil and vape.
In all those cases, you can usually get out old flavor by blowing good and hard through the battery end of the atty several times.
Those are just a few ways to test juices quickly without loading carts or cartos.
Hope this helps.
BTW...you might consider getting yourself an eGo or Riva USB pass through battery and a 510 atty

You'll love it.........and can probably be found for $20 or less
