Yes mate done a few swaps with another dripper, but they both have the same resistance Skwoddy

Update............ battery readings taken straight across the six 18650s in parallel. "Loaded" means with atty in use. The starting voltages for the day.
Day 1. 4.18V .....4.14V loaded
Day 2. 4.08V......4.05V loaded
Day 3. 4.03V......4.00V loaded thought it would be less, possibly because I had to put a new battery in the multimeter?
Day 4. 3.97V......3.93V loaded
Day 5. 3.92V......3.88V loaded Remaining capacity indicator down to 80%.
Day 6. 3.87V......3.83V loaded I owe it 6 hours - out power washing all day, gave me a chance to try out my MVP, excellent device . Still indicating 80% left on the power bank.
Day 7. 3.82V......3.78V loaded Owe it about 6 hours, in the garden all yesterday afternoon.Not practical to use it out there,a couple of hours Power Washing,then barbee and beers.
Day 8. 3.77V......3.72V loaded Been showing 60% on the capacity remaining from last night.

So we are at the 1 week mark It`s more like 6 days really because of the time spent on Day 6 and Day 7 vaping on something else outside.

So we are at the 9 day mark It`s more like 8 days really because of the time spent on Day 6 and Day 7 vaping on something else outside. Vape performance exactly the same as day 1.

14 June Friday. So we are at the 10 day mark It`s more like 9 days really because of the time spent on Day 6 and Day 7 vaping on something else outside. Vape performance exactly the same as day 1.Still getting the regulated 5V on the USB connector which is feeding the VV EGO USB adapter. Going to use the EVODalike from FT all day today, quite impressed with it, loads of vapour, flavour not quite up to the dripper though (but still pretty good)

15 June Saturday. We are at the 11 days vaped mark. It`s more like 10 days really because of the time spent on Day 6 and Day 7 vaping on something else outside.It is outperforming my expectations of it. I thought a week from those 6 batteries would be good, but this is excellent. If an EVOD or similar higher resistance atty had been on from day one it would be even better. The quiescent current must be tiny. There is one little led on all the time, but the current drain from it must be insignificant.

I reckon one of you barstools is sneaking in here overnight and charging it up a bit. Could this last two weeks? I hope not, it`s starting to do my head in lolol

17 June, Monday. We are at the 13 days vaped mark. It`s more like 12 days really because of the time spent on Day 6 and Day 7 vaping on something else outside.It is outperforming my expectations of it. I thought a week from those 6 batteries would be good, but this is excellent. If an EVOD or similar higher resistance atty had been on from day one it would be even better. The use of the EVOD with it`s higher resistance has slowed down the discharge of the batteries quite a bit. I have treated this experiment seriously and are missing the rest of my mods lol, so I think I will call it a day on this now. This form of vaping works very well, I have no doubt that I would have got past the two week mark if I had continued. If I had been using an EVOD from day one I think three weeks would have been much more than just a possibility. The Power Bank is still giving me 5, 9 and 12Volts on another output while I am vaping on the USB output, and it is still possible to charge my phone etc at the same time as vaping.

That`s all folks, where`s me Vamo?

Interesting.

For the sake of balance though should you not use your favourite mod with the batteries you had in the pack once each to compare results ?







Only kidding, would be interesting to compare the results vs the batteries in a power regulated mod though.



When away from home would be useful for anyone as a battery back up for all our tech though and a bargain at FT prices really. I seldom go away for long myself so don't really have need of it but thank you for the research.

[robby]

It really is a very useful device, while the 6 batteries makes it a bit on the large side for carrying around (although not impossible with some sort of carrier to strap it to your belt, or the ladies could put it in their handbag) it has been totally reliable and perfect for holidays. You could even go on a two week safari with this and be confident it would last for two weeks. Three voltages from it, all of which are still working accurately, even the 12V one. This thing does have a 3.7V 4AMP ouput as well, not tested yet. So a lot of watts available there as well (about 15). I have been pleasantly surprised at the very minimal power power loss when idle, I havent been switching it off at all until I go to bed, so it really has been on all day. I think with a power regulated mod there would have been quite a bit more power wastage, some of them would lose a lot of power just idling. This USB adapter must have been losing some, but it must have been insignificant. And you are right, you are only paying a fiver each for 6 very good high capacity batteries. You are just about getting the Power Bank for next to nothing.  vereybowring.

Thank you for the research robby much appreciated i have ordered the same one as you have on the 7.6.2013 from fasttech so hopefully it will be here sometime this week

[Die5el]

Just a little update i still haven't received my order fast tech my other orders came within 10 days though
