Maksi Mako*
THE MAKO
*5 volts by UK plug in only. Really shouldn't be on the list - get a PT instead.
What do you mean "really shouldn't be on the list"? The Mako is AFAIK the only TRUE 5v device in the whole list as it uses a 5v battery instead of some kind of electronic modification or resistance trick (read wasted power and lower battery life due to heat) to achieve 5v.

So if you want 5v without dramas the 5v Mako is a simple charge and vape device that does 5v the way it should be done, with a 5v battery. The Mako does 5v great without the worries of stacked and modified 3v batteries.

There's no such thing as a "5V battery", especially not with NiMH chemistry. It's either a 4-cell 4.8V battery or a 5-cell 6V battery with some kind of regulator built in. The very low capacity (400mAh) would certainly indicate a stack of much smaller cells. So the Maksi uses all the same "tricks" as a regular li-ion mod, they're just bundled up inside a battery pack instead of out in the open. You also have to deal with the memory effect and low discharge rate common to all NiMH batteries as well.

There are several good reasons that most mods use li-ion instead.

Thanks for pointing that out...........I was looking at the Maksi but the low mAh concerned me. I completely missed the NiMH issue. I would also guess those batteries are less readily available.

It's almost certainly a stack of 4 1/3AA batteries heatshrunk together. I've never seen a picture of the maksi battery, but based on the "also takes a 3.7V 14650" claim, this would be about the right size (14mmx67mm). So not really 5V (4.8V nominal) and certainly not a single battery. Plus all the other NiMH baggage. The alibaba link was the only one I could find, so yeah, not readily available. Though smokejuice.co.uk sells them for only 6GBP for a pair.

So what's wrong with 4.8v? These things were so cheap that I just keep 4 of them in rotation and as soon as they go down a bit I shove in a fresh one. No problems here. OK, call it virtual 5v, but if you rotate them you are at 4.8 anyway so it's all good.

Don't forget you can also vape the Midi at 6v with a pair of protected 3v if you need more.

There's nothing wrong with 4.8V. The problem lies with your original insinuation that the mako is a "true 5V device" (it isn't), that traditional 5V mods use "tricks" to get 5V (so does every electronic device that needs a non-native voltage), that the mako doesn't use these "tricks" (it does) and that the mako's battery solution was somehow superior to the usual methods (it isn't).

The NiMH battery chemistry has inherent flaws that do not exist with lithium-based batteries. Because of this, virtually all high-power devices use li-ion or LiPo batteries.

If you want a 3.7V mod that uses a single standard li-ion battery, some variation of the mako may be appropriate. But if you are looking specifically fro a 5V mod, the mako will be outperformed by any of the other options. Of all the "tricks" that mod manufacturers have used to get 5V out of a mod, using an inferior battery chemistry has to be the dirtiest of them all.


OK, I just measured a fully charged "4.8"v and it reads at 5.75v. So don't tell me that rotating freshly charged batts at 5.75v is not really vaping at 5v.
It's not. A freshly charged 3.7V li-ion battery will read 4.2-4.3V, but you certainly wouldn't call that "4.3V vaping". Well, you would if you were the manufacturer of the Maxx, but they're just lying. Measure that battery again after a few min of vaping. It'll be back down to it's nominal voltage.

I didn't say it's vaping at 5.75v, you just did. I said it's vaping at 5v which if you swap it out at 4.5 for a fresh charge to 5.75v it is as good as. I've been vaping this non stop for an hour now, I just checked the voltage and it's 5.2v. By the time it reaches 4.5 my next battery will be ready at 5.75v again. What's the problem with that?

Everything I just said. NiMH batteries are inferior to li-ion batteries in every way. Whatever voltage they vape at, they won't do it for long because they have such a low energy density. They also have problems with memory effect and poor lifespan in high-drain applications. They are the wrong battery for the job.

That may well be. But I primarily use mine at 6v anyway. The "5v" option is only that, an option. I prefer 6v to 3.7v with LR atty as the hit is much better. The point is, if you want some "limited" 5v action then the Mako can give you that. All be it, not up to your rigid standards. If that excludes it from "the 5v list" then so be it.

1 1/2 hours now, non stop vaping. Reading at 5.02v, at this rate it should be 2 1/2 - 3 hours non stop before I need to swap batts, at which point I will be at 5.75v again. Explain to me how I'm not vaping at 5v again.

If it is NOT regulated the voltage changes as the battery drains so technically you vape at 5 volts PART of the time LOL !?
Also to really know what voltage you are vaping at you have to measure the voltage LOADED or with an atomizer on it ( you have to use a custom adapter to do this measurement )

Anyhow 5 volts 4.8 volts Blah ? you really dont know what voltage you are vaping at with out testing it loaded

Fine, remove it from the list and add it to "the true 6v" list which is what I use it at. :toast:

No that was not my point at all Un ! I was just trying to inform you as to what is really happening .
Most likely you are vaping around 4.5 volts from all of the battery tests I have done.

Mod are NEVER rated at the loaded voltage , when using a regulator the voltage stays the same loaded OR unloaded.

So you can see why all the confusion.

I hope at least this helped a little in your understanding ?

Sure, no worries. I understand but I also know that using that battery is definitely no the same as using a 3.7 so it is more than a standard battery but your explanations have been noted. It's all good.

The Maksi uses a 400mah 4.8V NIMH battery..... however when full charged it is at around 5.6-5.8V..... I think this makes it closer to 5V would you not agree?

I'd like to point out that the 400mah is a true rating and not like many of the other batteries which state overly inflated mah figures. It also has quite a high drain band from as high as 5.8V down to 4.5-4.6V. So that's over 1.2V before needing to recharge. Comparatively, a 3.6V li-ion normally gets wimpy around 3.7-3.8V so the voltage band of a 3.6V li-ion is much less = 0.5V.

Another point to mention is while although NIMH technology is not as energy efficient when compared with li-ions, it has been around a lot longer and therefore has been perfected over time and more importantly is relatively safe when compared to li-ions. So you are getting a relatively safe portable 5V option with the Mako Maksi and yes there are no tricks involved. We do have US plugs available now and no this is not a wired up 5V option - IT IS A BATTERY!

To the poster (CANDRE) who said that NIMH is inferior due to memory effect.... are you sure you wern't referring to NICD?? Different technology and NIMH as far as I am aware does not have this issue.

So please amend your OP and CANDRE please can you stop making such defamatory statements:

'Of all the "tricks" that mod manufacturers have used to get 5V out of a mod, using an inferior battery chemistry has to be the dirtiest of them all.'

Thanks.

Perez-uzza to this day
I just got my buzz and it is pretty awesome. I'm using it with the new "premium" cartomizers (KR808D-1) and loving it. Note that it has a 901 thread without airflow - so you need a 901 to 901/808 to get proper air flow for the cartos. I understand notcigs will have some in stock, in the meantime I got mine from altsmoke and understand Nhaler has them in stock, or healthcabin if you are into China.

Anyway, I love it so far. It is new so I can't post a full review yet, but what I can say so far is that it has a great utilitarian design. The voltage adjustment is nicely placed and tucked in - no accidental adjustment, yet easily accesible. The adjustable voltage allows for custom tailoring just the right hit for the atty - I like big hits without burning my cartos so that is very nice. The button is smooth small and simple - not likely to be depressed accidentally. The LED is useful, not just pointless bling - it will indicate a shorted carto, low batteries, or good to go.

The thing I'm most excited about is to verify that it will deliver full power hits through the life of the batteries. I'm on a fresh charge now and planning to vape it dead and find out. My first impression is that this is my favorite mod I've used yet, and at an excellent price too - I don't want to suggest a price increase but I would have paid more for this thing than I did.

This is the first device I've had that I think I would tend to use even if I was sitting at my computer with my favorite PT plugged in. Which I am. Very nice.

There's nothing more disingenuous than trying to claim a flaw is actually a feature. NiMH batteries are inconsistent. The fact that they vary widely between fully charged and empty is not something to be proud of. This simply means that the vaping experience will vary significantly during the short life of the battery. In comparison, li-ion batteries remain relatively constant between full and empty. A regulated 5V mod (whatever the method of regulation) will provide exactly 5V for the entire life of the battery. That is far preferable to "somewhere between 5.8V and 4.5V" depending on charge level.

No, I'm definitely referring to NiMH. NiHM may have a less pronounced memory effect than NiCad, but it still exists. Li-ion, in comparison, has no special charge cycle requirements.

I would gladly amend my previous statements if any of them were inaccurate, but they are not. In fact, I'll say it again - NiMH is the wrong chemistry for e-cig mods. It is inferior to li-ion in every metric. I won't say that it won't work, but I will absolutely insist that it won't work as well or for as long as li-ion. This is a fact, and as such, cannot be considered "defamatory" under the accepted definition of the word. "Criticisim" might be accurate, but factual statements are never defamatory.
