I was playing a game on my PC with my T5 sitting on my desk. I reached for it and it wasn't on. I click it 5 times and nothing happens. I think battery might have died so I plug in the USB, nothing again. I think maybe my battery gave out. I try 2 more fully charged VTC4s and still nothing. My T5 has randomly died after 10 days of having it. Never been dropped. Never gotten too hot. I was using it with a .8 ohm single coil at 35 watts. Been working great until now. I bought it from VapeNW. I emailed them and Cloupor so I'm hoping someone will want to honor their product. It's a sad day.
