Whats this about the LavaTube not going up to a true 6 volts under load?

I did a review on it. It's in another thread in this same subforum.

In summary, the "regulated" voltage doesn't do what it is supposed to do. With a fresh AW IMR high drain 18650 reading 4.2v the most I could get out of it was 5.8v. With a half discharged battery at 3.8v remaining, that dropped to 5.6v maximum output, at 3.5v left on the battery, max output was only 5.3v.

I have the Black and Silver LavaTubes. Using 3 separate 3.0ohm Smoketech cartos in my Tubetank. I usually run about 5.1-5.5 volts with a 65%PG/35%VG blended juices. The volt range under load with my voltage meter shows me exactly what I have set it at. At 6.0volts my voltage meter under load reads 6.1 volts on my silver LT, and 5.9 volts under load on my Black LT. This was the same for all 3 cartos. On a 3.0ohm atomizer set at 6volts, my black LT reads 5.91 under load, and my Silver LT reads 5.98-6.09 under load. My LavaTubes seem to be working as intended.

It sucks that some people's LavaTubes are not fully working at higher voltages. I'm totally happy with my purchases. And I have a feeling that future runs of these units will get some of the kinks worked out hopefully.

Oh, and Happy New Year Everyone!

Mine was a preorder unit. Maybe they've revised it for the full release? If that turns out to be the case, I would send mine back under warranty, and re-review the new version. A-hem... Volcano?

Perhaps "preorder" should have been noted but regardless the reveiw was top quality and I for one greatly appreciated it.

Thanks everyone.

The way I look at it, I already own a Riva 3.7, a 5v Box Mod and 5v Passthrough. I've experienced vaping between those ranges. I have not experienced 5v up to 6v and that's an important reason to get the LT VV.

I won't use it so much to adjust for flavor of the juice unless I can do it without going down too much in voltage. I like the stronger nicotine and more vapor of the higher voltage.

Some have a red indicator window and some a blue. No way to order which one you prefer. I'm hoping I get the blue and the voltage is true up to 6v for me because if I only get 5.3 out of it, that's not gonna give me the experience I'm looking for.

Kinda leery in the first place about using any mod that has a booster circuit bumping up a small 3.7 volt battery. ( perhaps I should have ordered stronger than 1600 mah) I'd be more comfortable with two 3.7 v batts that are regulated down to 6v so I'd know the true power is there. I may have to send this thing back for an exchange if the voltage don't go up to 6v and keep doing that till I get the unit that's working as advertised. We'll see when it comes in.

I'm keeping my fingers crossed.

I asked about this issue in the Volcanoecigs forum and I got this reply

5.8v is normal under a load for any boost mod dialed up to 6v. If you dial them to 5v, under a load you'll get 4.8-4.9v usually. You would need to dial it up to about 6.2v-6.4v to keep it at a steady 6v under a load and I don't think the board goes that high. If you want a true 6v steady under a load you have to use a dual battery mod with a regulator that drops the voltage down. Even then it can take a few seconds for the regulator to adjust itself under a load.

This means even the over esteemed (IMO) Provari won't even go above 5.8 v under load. I take some comfort in that.

My reply

I think I'd be satisfied at 5.8 v. for a top voltage.

At 5.6 v and a 3.0 ohm coil your pulling 12 watts. At 6v you'd be pulling 13.65 watts. Those ranges are pretty hot.

I just don't want the unit to at least not get me close and therefore satisfied.

If I need hotter than that a slightly lower ohm coil at higher voltages could get you up to the 15, 16 and 17 watts ranges with 5.8 volts.

The coils I'll most likely be using are rated 2.8-3.0 ohm.

Actually, my Provari puts out exactly 6v under load in the same conditions I tested the Lavatube under.

Actually, the under load voltage of the Provari is always spot on with the set voltage under all circumstances.

Ha ha, you popped my Happy Bubble. LOL but seriously, so therein is a major difference in the booster circuits of each mod. Interesting. Do you really find there is much of a difference between 5.8 and 6 volts?

John, honestly, I really wouldn't know. I personally don't vape that high (highest I usually go is 5.2v). My only issue is that volcano advertises that the LT is regulated 3.0-6.0v. I just wanted to see if it really could do what they claim it can.

Btw, I'm not just picking on the Lavatube. I put the Provari through the same paces when I got it as well. There was no need to post a review about it because it performed exactly as provape said it would. I will hopefully soon acquire a buzz pro and will again do the same kind of testing to it.

I think it goes deeper then that. There isnt a big difference in .2v, but after a hour or two most people cant get more then 5.3 when its set at 6v. A .7v difference IS a big deal.

Would using the 2200 mah battery help with that as opposed to the 1600 mah do ya think? I ordered 1600's but if this turns out to be a real problem I'll upgrade.

Why is it wrong to expect the cheapest option to do as it's advertised to do......I'm personally not gonna just "lay down" and accept sub par performance when I effectively entered into a contract for an item that is stated to give a certain level of performance. As far as I'm concerned I've entered into a 1 year contract with Volcano (warranty) and I will get the performance level that I have been promised which could potentially mean the revision they get this thing right. The below would be acceptable in my opinion as is stated in the instruction manual but only if it's official which I have no idea.....We are all entitled to get what we pay for as stated regardless of price. The below standard though still doesn't meet the definition of "regulated" as defined in the LT specs. I'll have much more to say once mine arrives later this week and I run it through its paces. Hopefully this rant just turns out to be a waste of my time and a little space. All will definitely be forgotten if it vapes as promised and I'll rave about the LT to everyone who asks....that's good business Volcano...distrubute a product that works as advertised.:)

[h=2]When to Charge the Lavatube[/h]
Press the Lavatube’s power button seven times in succession to see the current charge level of the battery. The screen changes to display the current voltage between a minimum of 3.3 and a maximum of 4.2. The Lavatube uses a voltage booster to raise the battery’s output to a maximum of 6.0 volts. When the power level drops to 3.5 volts, it is nearly time to charge the battery. You will also notice that the vapor production of the Lavatube drops slightly at this point, because the booster can no longer bring the power level of the battery quite up to 6.0 volts
