Vape I just got back from a trip to Amsterdam, and while I was there I did a little experiment: could I get 2-3 days battery life from a dual-18650 vape mod? Almost! I got real close, and this is how I did it…


Amsterdam. Itโ€™s a wonderful place, a place packed with good people, culture, great food, stunning architecture, and coffee shops that sell weed.

With this in mind, itโ€™s no wonder that Amsterdam has been voted one of the happiest places to live on Earth โ€“ย itโ€™s currently ranked #6.

I just spent a couple of days in Amsterdam with some friends and my fiancรฉ, thatโ€™s us below.

And while I was there I conducted a little experimentโ€ฆ

Could I ACTUALLY get through 2-3 days on a single charge from two 18650 batteries?

Dual-18650 Vape Mod Battery Life โ€“ Would It Cut The Mustard?ย 

Thatโ€™s basically around 40+ hours of vaping, give or take, as I donโ€™t vape when I sleep. But even with this taken into account, it was still a pretty tall order.

I knew I couldnโ€™t use a sub-ohm tank or a rebuildable, as they require too much power. The only tank I owned that might do the job was my Kayfun, so that was my weapon of choice while on vacation.

The mod I used? UWELLโ€™s Ironfist, which is a dual-18650 mod that looks kind of like a Lambo with its loud, in-your-face yellow and black chassis.

As for the batteries, I opted to go for a fresh set of FOG STAR Batteries (18650s, obviously).

With E Juice, I took a combination of standard E Juice (60/50, 6ml Nicotine) and a couple of bottles of Yami Salts. You can run Nic Salts E Juice through a Kayfun, as theyโ€™re not sub-ohm.

Nic Salts give bigger hits, so, therefore, you vape less.

And Iโ€™d need to cut down my vaping if I wanted to get through three days of use from a single charge.

Did I Take My Vape Battery Charger Too?

Of course! I had no idea whether this experiment would work or not; I also knew Iโ€™d be drinking as well, and the more booze you drink, the more you vape.

From the outset, I wasnโ€™t confident.

But I knew the Kayfun ran at very low wattages and still performed, so I was pretty convinced itโ€™d make it through at least a couple of days.

Soโ€ฆ How Long Did My Vape Modโ€™s Battery Life Last?

Amsterdam!

Day One

By the close of Day One, with very moderate usage, Iโ€™d run the battery down to 70%. Not too bad. But still not good enough for the experiment; I needed to make it more efficient.

Day Two

So, on day two, I ensured that when I wasnโ€™t using the mod I turned it off.

This way, any idle power sipping would be nipped in the bud. Annoying, yes! But it worked.

At the close of play, Iโ€™d used less than 20% of my remaining battery life.

Day Three

And this meant I went into day three with just over 50% battery life on my vape mod..

This was also my last day in Amsterdam too, so I was feeling pretty confident by this point, so long as I was careful with usage and I switched off the mod when I wasnโ€™t using it.

Then Death Came Knockingโ€ฆ

When did the mod eventually die? It didnโ€™t happen in Amsterdam! Nope, it made it all the way home, finally dying on the drive back to my house from the airport!

But thatโ€™s still a really impressive performance: 3 days from a single set of 18650 batteries.

Itโ€™d be impossible to do this with a high-power sub ohm tank or a rebuildable atomizer, so the key here was the Kayfun tank.

Why Kayfun Tanks (And MTL Tanks) Are Great For Battery Life

Itโ€™s kinda simple, really: a standard mesh coil vape tank will run anywhere from 50W to 100W, and even with three batteries, this will still run down pretty quickly โ€“ย more power means more battery drain.

Conversely, my Kayfun tank runs in and around 10W to 15W, if Iโ€™m feeling fancy, on a 1.4ohm build.

This means it sips power, leaving plenty of juice left in the cells for prolonged vaping sessions.

The Kayfun is an MTL vape tank, meaning it draws like a cigarette. Itโ€™s also rebuildable, itโ€™s basically an RTA, but because of its tiny deck, you canโ€™t really run it as a sub ohm tank.

But! A Kayfun produces great vapor, even at low wattages, and insanely precise flavor, especially when used with PG-heavy E Juice โ€“ย you want, nay NEED, that throatiness when using an MTL tank.

And this is why I always use Kayfun tanks when Iโ€™m out of the house, on nights out, or long drives. Itโ€™s better than a pod mod, just as convenient, and you get brilliant, precise flavor.

The only downside? Kayfun tanks are expensive; like $119.99-expensive!

Thatโ€™s a lot. But for me, the Kayfun pays for itself in a variety of ways; the most notable being its positive effect on battery life and overall flavor.

There are cheaper MTL tank options, however, and the โ€œnext bestโ€ option, in my opinion, would be Innokinโ€™s ZENITH tank which retails for around a fifth of the price of the Kayfun V5.

Is it as good? No, not even close โ€“ย thatโ€™d be like comparing a Fiat to a BMW โ€“ย but it is definitely a very good vape tank.

The Kayfun is just an exceptional piece of hardware (thatโ€™s why it costs so much!).

TL;DR โ€“ย if you want 2+ dayโ€™s worth of battery life from your dual-18650 battery vape mod, get yourself a Kayfun tank. Mine just did three solid days of vaping in Amsterdam, and it didnโ€™t miss a beat!
