If you don't mind my input, you guys and gals really need to do some research on Chargers.
Batteries and chargers or Google the Charger Make and Model in question and the word "review" for other sites.
Many Chargers don't follow the 18650 Battery Specs very well for
Proper and
Safe Charging. Look at the ones mentioned in the last few posts, and compare them to the Xtar SP2 and the pila. Even if you can't fully understand everything that's said, look at the Charging Graph Pictures, notice how UGLY some of them are, and read the Summary.
When you read up on 18650 Batteries, you find that, for the Best Performance and Best (Longest) Battery Life, it's best not to Fully Discharge them, and it's best not to Fully Charge them, i.e., not all the way up to 4.2V, and
especially not OVER 4.2V. This is another reason I want the new Joyetech 3400 Battery. I can Vape all day, Discharge it about 1/2 way, and Charge it over night. About 1/2 Discharge is Best, and the Charge should be terminated at 4.17-4.18V.
The pila is very highly rated, but can be
touchy. Walk on the floor too hard or bump the table the pila is on - the pila can turn Off, and you have to Reset it to get the Full Charge.
The Xtar SP2 is the best I've found, and GotVapes will have it in stock soon. It's already available elsewhere. Super T Manufacturing usually has it (there are others). And it's cheaper than the pila!!!
Review of Charger Xtar SP2
I want the Xtar SP2 because it has two Independent Charging Trays (meaning the Charge Rate of each Battery is controlled separately), and it can Charge at 0.5, 1, and 2 Amps, in case I ever get a Lithium Manganese. However, the 18650 Li-Ion Batteries are best Charged at the 0.5 Amp (500 mA) Rate. Charging a Li-Ion at 1/5 to 1/4 it's mAh Rating will give it the Longest Battery Life Cycles.
Not knowing how long it will take to Charge the 3400, I'm getting two Batteries and the Xtar SP2, so I can Charge one and use one, and have a Backup for worst case.

For the eVic USB Cover, it's a little tricky at first, but once you get it in the first time, it's much easier thereafter. Just press it firmly on the Top and the Bottom, and kinda wiggle it down into place. It'll snap right in.
I hope this helps
