Hey guys,
recently I got an ecig, it was the eGo-w.

I had 2 issues with it,
the first one being;

The liquid seemed to drain really quick, and I had to refill it about 3 times in 2 days.. (each refill about 0.8ml of the tank)
Anyone can tell me what causes this (note that I got it 2nd hand from my friend)
Does the battery cause this? Or can the battery affect the flavour or anything else?

The 2nd issue is the big one and what I'm really curious about..

As you know, I got it 2nd hand from my friend and it only came with the ecig and a bottle of liquid and obviously, the charger.
But there was no user guide/manual and I totally forgotten to ask him how long to charge it/how to check if it's done charging.

So then, I was charging it at night via USB with my pc. I left it there and didn't touch it at all with 0 knowledge of how long it takes to charge. (Naive!)

After about 1 hour 30 minutes, I smelt something really bad (the mercury leaked out, there was liquid and of course, I didn't know that this was possible)
So I was really curious about what liquid was it, and I went to get a cloth to wipe it off, when I got back, I touched the e-cig and it was super hot, almost
as though you would put your finger in a frying pan at 110 degree celcius. I was pretty shocked and removed the USB cable from my pc right away,
and 2 seconds later the battery exploded, LITERALLY.

There was a small fire on my carpet and it was very near the plugs and many wires, so I was really worried.

My question is, is it my ecig's battery problem? or will this happen with any other ecig?
Also, I really didn't know it would take so fast to charge up..

Help guys!
