I had a brain fart, I remember you were investigating wall power. With a couple decent cells the battery life will be pretty good I imagine and I bet packs will last longer too. That stock battery isn't very good for longevity from the info I read online. It's sad to think the cells weren't just better in the first place considering the cost of the pack.Yeah, I had my MV1 hooked up to a meter and bench power supply while investigating options for powering it. It pulled about 5.5 A (rounded up above) when pulling max power heating up from cold. That's about 45 W for the heater, very similar to other fast on-demand vapes.
I was hoping to find a cheap corded option for power but it didn't work out. Laptop style power supplies capable of delivering > 5 A and > 8 V are more expensive than I wanted to bother with. My bench supply isn't in a location where I want to use the vape. The easy battery cell replacement hack put a new light on things.
