3.7v vs. 5v?

[lemonshrew]

I'm getting ready to buy another mod (a Foxy Box) and I'm trying to decide if I want the 3.7v or the 5v. I currently have a Provape which is 3.7v. I've never used a higher voltage device. My husband still uses KR808d-1's. Part of the reason I want a new mod is to get him onto something better. The KR808s are not working for him. I'm happy with the Provape, but I'm not happy with the 510 carto's.

The pro's of sticking to 3.7v:

Already have LR cartos and atty's.
Won't have to invest in new batteries/charger/etc.
Familiar with what works, what doesn't.
I like the size of the 3.7v foxy box, which is the reason I want another mod. The Provape is a little big to handle when I'm not at home.
​

The con's of sticking to 3.7v:

Bought 2 packs of LR carto's filled 7 of them. Every single one tastes like burning carpet. I don't know if it's the brand, or if they sent me the wrong carto's or what. The dual-coil carto's work fine (although I'm not overly impressed with the amount of flavor). Atty's are the best, although I still can't get rid of the metallic flavor.
Maybe I'm doing something wrong, but I have a hard time getting the 510 stuff to work. KR808 wasn't great, but it was easy.

At this point I mostly drip. Best flavor by far! Problem is, my husband will take some time to figure out that it's worth it. So in the meantime, I need to get him some reliable good-tasting carto's. If all of the 510 stuff is like this, he won't bother with it. Most people on this forum who use 510 seem to be happy with it, so I'm inclined to think most people are not having this problem with the 510 stuff.
​

Is my problem voltage? the QC of the carto's? the LR?

Would using different cartos/attys at a higher voltage give me the flavor and hit I need without the hassle?

Would 5v make my life easier or harder? Part of me thinks I should start over with new stuff and give up on the 3.7 LR stuff. The rest of me figures that's probably not going to help. It sure won't help my wallet!

Also, I would like to get an adapter and use my old kr808 carto's, but I figure they will burn out at 5v. But, I have no idea if they will work at 3.7 either so . . .

Thanks for any opinions!

BTW, my plan is to buy 2 foxy box's if they work for us. I'm gonna get one to try to get hubby into the action, and if it takes I'm gonna get one for myself as well.

Personally, I own a 5v Foxy with a 3.7v in the mail as we speak I can attest that the 5v is great little mod and performs very good! I also have a Variable Voltage MonkeyBoxx, but the great thing about the Foxy's, is that I can take them everywhere I go (without worry to dropping or losing a $200 mod). That's why I am getting a 3.7 as well, because I like the best from both worlds.

For performance, I'd say you should at least try the 5v - I love how liquids taste at higher voltages. I use standard 2.5-2.8ohm attys on 5v with no problems. I've used 3.0ohm cartos and 3.5 attys (which would be around the same as 3.8v on a 2.0ohm) and they work wonderful as well.

For size, the 3.7v I haven't held in my hands yet, but it is obviously smaller than the 5v. But! The 5v isn't HUGE either and I think it feels great in my hands, personally.

As far as batteries/charger goes - both the 5v and the 3.7v take 14500 900mAh and the same charger respectively.

If you do not have any 2.5ohm + attys/cartos, then yes, you'd have to purchase some. But, if that was the only thing holding you back, I'd say give it a go.

As far as your old 808 cartos, what resistance rating are they at? If they're 2.5 + I don't see what they would burn out? Some juice, imo, tastes better at higher voltages while others taste better at lower. That's I went with VV for my first mod, so I could figure out with little hassle which juice would be great with what voltage. Which is why I am recommending the 5v now, because you already have 3.7

But, whatever decision you make, I believe you'll be happy with the Foxy Box. Steve does a great job soldering and assembling them and they're pretty durable little guys. Good luck!

Try the 5V it's new and different!! (take that with a grain of salt, I love to try new stuff )

You can use almost any atty or carto at almost any voltage if you use your thumb to regulate
the heat. If it tastes burnt, let go of the button sooner, or pulse it on and off while drawing.
Simplest VV "mod" I've found, works every time, can't overheat if the button isn't pushed...

 

[lemonshrew]

Thanks Levitas! I was just thinking the same thing; since I was planning on getting 2 anyway, I should get 1 of each! With his prices I can actually afford it!

Unfortunately, I don't know the resistance of most of my old carto's. I bought them from one of those sites that won't give you any details. It actually took a bit of digging to figure out they were kr808's. I can't find any details on the carto's.

I also have some of these from COV:

High Performance Regular Resistance 2.8-3.0 ohm cartomizers​

But, I haven't been able to get them to work at all on my old kr808 batt's, so I figure they're the wrong ohm or something.

I'm going to get the adapter and give 'em a try.


I also have some Smoketech dual-coils. I'm trying to figure out it they will work on the 5v. COV says they will, but I'm massively confused about the ohm thing. The description from their site:

510 Dual Coil Mega Cart 1.5 +-.2 ohm, in steel. Dual 3.2 ohm coils in parallel giving a total resistance of approximately 1.6 ohms. These produce great amounts of vapor due to the greater heating area of the dual coils but have less potential to burn due to the higher individual resistance of each coil. Keep them WET! They will burn if you run dry! These hold about 25 drops of e-liquid. New improved filler material is more absorbent. NOTE: Will not work with eGo, 510, 901 or mosfet driven type batteries. The Dual Coil should to be used with 3.7 volt mods with a switch capable of handling 2 or more amps. The Dual Coil work great on 5 and 6 volt devices. Your results may vary and the protection circuits on some batteries at higher voltages may see these as a short and not work.​

What do you think? Have you tried the dual-coils on 5v? Does somebody sell dual-coil's that will work on 5v?

Thanks!

I haven't tried the dual-coils on a 5v but, I have a sample on the way and numerous people have told me that you CAN indeed use them on 5v. Not only that, they say it's BEAST! So, I would say yes, you can definitely use them

Good to know Stosh! I can't wait to play around with it!

Fantastic! They give fantastic vapor on the 3.7 (maybe I'm just spoiled on the atty as far as flavor goes).

I'm well familiar with underperforming cartos, as the ones I tried initially turned me into a savage anti-carto bigot for months.

In the end, I was converted by the 801 Fushion sold by Ikenvape: 801 Fusion Cartomizer

Mind you, dripping delivers superior flavor to anything in my experience, but as cartos go, these are a reasonably close second. You'd need an 801/510 adaptor of course, but those aren't hard to find.

As to the 3.7V/5V voltage question, you can do an end run around around the problem—gain all the advantages, suffer no drawbacks—with a variable voltage mod. Granted, you'd have to spend more initially, but if I had all the money I'd wasted wandering from fixed-voltage mod to mod, I could buy about three more VVs.

I spoke to someone that was able to use a 1.6 dual coil in their 5 v box mod, but I have tried, and the batteries shut off. I am, however using a boge 2 ohm carto at 5 volts with RY4, and so far so good. The right place to be at 5 volts is around 2.8 ohm in my opinion. Cigar Man was going to try the 2.0 ohm dual coil at 5 volts and have not heard back from him.

As far as testing attys and cartos for resistance, if you dont have a multimeter, you should pick one up. It takes all the guess work out of attys and cartos.

Thanks! I will check those out. Are they special because they are 2.5 ohm, or is it something else? I'm afraid I don't know much about ohms.

Good point PI. I have looked at the VV's, but that quickly starts getting out of my budget. I'm sure, like you said, it would be more cost-effective in the long-run. But, coming up with the money now is always a problem for us poor people
Maybe I can save up for one one of these days. My husband already laughs at me and my new "hobby".

Good idea Steve, thanks! I'm looking forward to my Foxy Boxes! I'll get in touch with you soon to make my first order.

Anyone know where I can get one at a reasonable price? (By reasonable, I mean dirt cheap .)

Thanks! Can you recommend some "strong" flavors? We tried RY4, (can't remember from where) but it wasn't very strong. I've got it in my steep box now, and it may be better from somewhere else. I'm not really a fan of the tobacco flavors anyway, but my hubby seems to like them.

We tried Boba's Bounty and he loved that, but it made my mouth sore, and it not only made his mouth sore as well, but caused a big ole sore to come up on his tongue. There must be something in it we are allergic to or something (although, it's kinda weird that it would bother both of us). We've both used 100%PG and 50/50 PG/VG mixes with little trouble.

He is still on analogs, so his taste buds haven't recovered like mine. I offered him a taste of my chocolate the other day, and he said he couldn't taste anything. It wasn't an overwhelming flavor, but I could definitely taste it.

I'm gonna have to find him some "powerful" flavors to get him off those analogs.

KBV rice krispity treat to me is one of the most flavorful I have tried (that I love)

It's awesome on 3.7 with a LR carto or dual coil

 

[emus]

I've have RN-4081, 510, M401, Joye 306 (1.7ohm and 2.5ohm), dual coil 1.6ohm.
Mostly 3-3.7v. RN4081 at 5v 4ohms.

dual coil carto at 3.7v produces warm vapor and powerful TH; the most unique one.

Fav atty is 306 3.7 v at 1.7ohm and 2.5ohm.
Have to be more careful not to burn juice at 8watts(3.7v 1.7ohm).

What I find interesting is I get big clouds and TH w/ all of the above if they are wicking good and juice burns clean.
The biggest variable I've found is draw and and wicking; not TH and vapor production.

You want something to make you life easier, I say get a passthrough in both 3,7 and one in 5 volts. Use the passthroughs while sitting at your computer at home and save the batteries for when you go out.

 

[BuzzKill]

There are some low cost VV devices out there for a low $$ ( not all of us have the extra funds for top of the line stuff ! )
I think there is a kit out there that is around $35 ( I cannot for the life of me remember who has it ???? )

BUT being able to adjust the TH and flavor is " Priceless "
