Looks like it needs some sort of 510-510 adapter to fit on a regular 510. Where do you think I'd find them?

The "T" fits on a regular 510 just fine. Looks a little stupid, but it fits just fine. I don't know if it will fit on the swingarm of the Darwin without using an extender (interference with the Darwin body perhaps?)...... but if it did need and extender you can either use the eGo charger extender or just stack two adapters (501->901, 901->510).

I used the Darwin, with many different atties - same ole juice, and my battery lasted me a little over four days. However, I did notice that today was not a happy vaping day for me at all. Could it be that the battery takes a dump toward the end? If so, is it okay to let it do this regularly or no? Sorry for so many questions, but I thought that this was to be a benefit of the Darwin - no noticeable battery discharge?

Still a very happy camper using the standard 901 on the Darwin. I found my vaping happy, yet again. :wub:

It seemed I ran through my battery pretty quickly as well today, too. I'll have to pay attention to how much I'm vaping to see. Looks like I may get snowed and or iced in tomorrow, guess it'll mean more time to play with this. I'm wondering if the LR drains the battery faster than a reg. or HV one.

From what I understand, Lithium Polymer batteries have a discharge curve that drops off more rapidly at the end of a cycle. The batt indicator will not show depletion until about 1/3 to 1/2 way into a full charge cycle. Then the indicator will start to drop and drop disproportionately fast. So, the bars of the indicator are more likely to be showing the last half of the overall charge cycle.

Lithium polymer cells need (I have read) a full 3 to 4 hours to charge. So, if the indicator shows a full charge after only 2 hours of charging, leave it charging the full 3 to 4 hours.

Analogy: some car gas gauges stick at the top and then drop off fast.

Edit: Remember that Darwin has smart charge circuitry so the charge cycle turns off when full. I do as Clyde posted (below) - I just plug it in when I go to bed and wake to a full charge every morning. These batts are rated for around 1,000 charge cycles and have a full 1 yr warranty so i just charge it each night and know I will have a full charge that will last me all day. I do the same with my cell phone.

This is the best method. Unlike older battery technologies (NiCad, NiMH), lithium-based batteries prefer shallow charge cycles rather than deep cycles. This means that they will last longer if you keep them topped off, rather than draining them down to empty then charging them back up again. The closer to full you keep them, the happier they'll be. Just because you can get 3+ days out of them, it is still preferable to charge them every night if convenient.

This goes for prismatic Li-Ion cells as well. Those that use 18650 mods will do better by their batteries to recharge daily instead of waiting several days for them to run flat.

You can find them at Avid Vaper.....I keep one of mine all the time.

Many thanks, y'all!

@ nebula - that is exactly what I experienced yesterday, so glad that is normal.

@ candre - again, spot explanation for me. I would rather do short charges than the long, agonizing charge like yesterday.

@ Clyde - *sigh* now I have to find another outlet by the bed. lol. 99% of the time I charge my Droid that way.

Many thanks again to all for the help. :)

Got another day out of the LR510 carto...not a bad experience vape wise on the darwin. Bit more forgiving than the LR510 atty. But my battery seemed to go almost completely down in one day. I know LR's can drain li-ons in short order...blah, blah, blah, amps, resistance, etc. Or maybe I vaped an insane amount. Possibly the batteries need a few charges and discharges to reach their full potential. Will definitely keep an eye on battery life.

Moving on today to a 3ohm 901 atty. Was hoping that its physical characteristics (ie the inlet hole on the side) would make it a little more dripper friendly and allow it to hold more juice. It may be a little bit better than the 510, but not by much. :sad: And in general between these attys, the 901 has better taste, the 510 superior TH. Running it a bit cooler than the other combos, at roughly 8 watts. And, oddly enough, the darwin matches this wattage rating to the atty's resistance to produce 5 volts of output. I'll try this for the rest of the day, but it is NOT my favorite setup so far. May take my last specialty i6 GG atty (901 golden greek made for vaping at 6v) tomorrow to see how that does.

Time and weather permitting (not today due to the blizzard) I'll have to go down to Sternos and talk him out of a 510 to 801 adapter and a HV 801 atty.

Got some clearomizers in route, and will be ordering a couple of adapters online, to include a 510 extension. Thinking I'd like to try a map tank mod (either premade or home brewed) and/or possibly an ato-miser in the near future. The Cisco 510's will also get their time on the firing line, too.

With a constant-wattage system, this shouldn't be the case. 8W is 8W, whether you're using a 1.5ohm atty or a 3.5ohm atty. The drain on the batteries should be the same* either way.


* There may be minor fluctuations due to efficiency variations, but they should be unnoticeable

I have been looking into these, so am quite interested to hear your thoughts on them. Where are you getting them from? And which revision are the ones you're getting?

For those considering the 801 series attys (801, BE112, 302, 4072), in their various resistance versions, you might consider having a look at this comparison of 510 to 801 adapters.
http://www.e-cigarette-forum.com/fo...dapters-w-pics-airflow-attys-little-help.html
It is NOT conclusive but it did help me to get a better handle on the various adapters I was receiving from vendors and which seemed to work better (for me) with different attys.

For any unfamiliar with the 801 series attys, each model has a different airflow intake design (each having more or less airflow as compared to the others). So, trying to match the adapter to the atty to get a draw that is not too tight or too airy becomes a challenge. Unfortunately, most vendors have no clue about these differences in the adapters, which adapters they have or which of the adapters they have work better with which models of the attys.

I have never dissected any of the 801 series attys to compare the innards but I am confident there are internal differences too. While airflow is a BIG variable, there is too much consistent variation between these 801 series models in flavor, vapor and TH for it to be all attributable to only the airflow factor.

Hopefully the comparison will help others to compare what they have, see some others and decide if they want to look for and/or try different ones. Like juices, devices and all vape gear - ya gotta try it for yourself to see which YOU like "best".

EDIT: PS - I find the ariflow changes noticeably from attaching an adapter to the atty first compared to attaching the adapter to the device first. You might consider experimenting with these variations also.

A couple of questions...

nhaler's website doesn't list a phone number. Are they US based? I've never ordered from a company I couldn't call on the phone. I'm suspicious of companies I can't call on the phone. But, apparently, they're the only place selling the Darwin, and a coworker wants me to buy one for him (he has no credit card).

nhaler's website doesn't appear to offer Darwin for sale, it just says "out of stock". I know it's out of stock, I expect it to be backordered for weeks. How do I place an order?

NHaler/Drew has his own thread in his subforum: http://www.e-cigarette-forum.com/forum/nhaler/151096-darwin-evolv.html You might consider PMing Drew or emailing them thru their site.
