Jsand, I thought I would offer a few more tips that I hope you will find helpful.
Batteries: Charge them when you receive them. They will only be partially charged. Unscrew the battery from the charger as soon as it is charged. The good news is that these batteries will tell you when they need to be charged. Start any new juice and/or clearo on the lowest voltage and work your way up. Check and clean your battery connector (use a bit of paper towel or similar) every time you remove your clearomizers. It can lengthen the life of your batteries. Use the case whenever possible. Start charging the battery as soon as it drains so you won't be caught without one that works.
CE4 Clearomizers: Don't fill them with juice above the wicks...stop where the wicks come out of the white plastic part in the middle (or maybe just a little below). After you fill them, lay them on the side so that the juice wets the coil. The coil is near the mouthpiece on these devices, so you may need to tilt your battery up to vape when the liquid gets low in the tank. If your coil doesn't get enough liquid, it's called a "dry hit." You also might want to label these clearos since they will look alike. Some use colored rubber bands, fingernail polish, or scotch tape/markers. Do what works for you.
Evod Clearomizers: These are filled from the bottom. Be sure to not get juice down the tube in the middle, and drip the juice down the wall of the clearo when filling. Only fill it so the level of the juice is just below the opening of the tube in the middle.
You'll eventually want or need more equipment (it happens to all of us

). I would suggest a passthrough battery, which you can use charged
or plugged into electricity (USB port, car, wall, etc). This way you will almost always have the option to vape, even if the battery is drained. If you like the CE4 clearo, consider getting a
CE5 or similar device. You can replace the coil heads of them, and it will be cheaper than always buying new clearos.
You can use Google to search "discount codes" and the name of the vendor, and you can add "ecf" to find ones mentioned anywhere on the forum. Check
