Hey there, sensfan15!
You say you're trying to
vape with your MVP2 charging after 3 days - which I would assume ran the battery down about as low as it will go and still fire. My guess is that you just need to give it a minute to charge up on its own so that it can maintain the power needed to fire while still charging. Also, don't forget to always check your atomizer's resistance when a coil won't fire on a
device. You have no idea how often a slightly loose topper will throw a person off when it doesn't make contact and fire.
Just as an FYI, you can press both (at the same time) the 'P' and 'U' buttons on your MVP2 (and then release) to check the atomizer resistance as well as the voltage left in your battery. These numbers are represented respectively as an 'A' (it's supposed to look like an 'R') for the resistance, and 'U' (supposed to look like a 'V') for the remaining voltage. In my opinion, the MVP2's performance starts to degrade below 3.8V which is when I begin to charge mine.
Hopefully this is the case and nothing is wrong with your MVP2 - it really is a solid
device!
