MVP Owners Group-into the next generation

[Night Hawk]

hi everyone, I didn't realize there was a thread dedicated to MVP batteries and actually just posted this question on the main board...but I'm hoping that perhaps you can all help me..

I got my new Innokin MVP 20 Watt's in today..

The batteries came with the standard USB cord..much like the ones that come with most cell phones these days. I'm currently charging it via my computer..but, I have several AC wall adapters and I'm wondering if I can use those.
The manual for these batteries recommends a 5V 500mA USB wall charger, however, when I looked at the ones that I have, they are rated OUTPUT: DC 5V 850mA

Are these still okay to use with my battery..or do I need to buy a wall charger specifically rated 5V 500mA

I'll keep charging it with my computer if needed for the time being, but would much prefer to plug it into the wall...I just don't want to fry it or something until I better understand what this means.

If you have an ac wall adapter with a 5v usb port that will work! I charge the two MVPs here one being the older 2.0 version with a 2A two port porable charger being a 12,000mah battery with two ports. 1A for each when divided. With any regulated mod the current will only be drawn until the charging circuit detects a full charge to the battery and then shuts itself off automatically.

For charging straight current directly into batteries without anything in between on the other hand that would be a problem you won't be seeing. Here I grabbed a Sharp alarm clock with two ac outlets and a single port I use for charging everything up on without any problems. The charging citcuit regulates just how much current is drawn even when there is a surplus available. Always check when charging just the same in case something starts getting too warm which then would indicate a problem of some type.

Well... good... bad... that perspective. I would generally say that's a good thing, because you must be running pretty low wattage and not vaping a lot of juice. If you are happy, then it's probably a good thing.

I usually have it set to 3.7V I don't fully understand the whole VV/VW thing yet so coming from the Vision Spinner II I am use to the Voltage setting. How does the VW work? I have read elsewhere that in VW mode the MVP automatically sets the Voltage for the detected coil. If this is true then I'm to understand that if I put a tank with a 2.1ohm coil on my MVP and set the VW to say 7.5W then I have no fear of ruining the coil? Or even if I set the VW to say, 9.5W then my coil will be safe because if the VW is too much the MVP will automatically adjust? Or is this incorrect? If so, please let me know.

 

[ian91]

The calculation is Wattage = Voltage squared / Ohms. So for your purposes Voltage = Square Root(Wattage * Ohms)
A 2.1ohm coil at 7.5 watts will return a voltage of 3.97. At 9.5 watts, it is 4.47. I would start at 7.5 and work your way up. My wife uses 9.5 watts with a 2.1 ohm coil and she seems to like that. She started out around 7 watts.

Thanks you Night Hawk...
All the USB AC adapters that I have are all rate 5V...I think one is 1000mA and this one I was going to use is 850mA..
So based on what your saying, I should be fine with either one...?? Right?

Thank you again for replying...much appreciated.

To simplify things a little that would be V times V divided by the resistance so 4x4 is divided by 1.8ohm where you then need to calculate the math according to some or simply use the wattage setting until you reach the one where the best results as far as flavor and vapor are found. For a full description a good reference for understanding Voltage vs Wattage more fully you would go to Vape Store Directory – Variable Voltage (VV) vs Variable Wattage (VW) Vape Devices

The 1A or 1000mA shouldn't be any problem since the MVPs have a regulation on how much is drawn while the company will make a certain recommendation for the 500mA since that is the minimum requirement in order to see the battery fully charged. Many an adapter are only 400-450mA and would be useless from not being adequate.

With PC port charging that is actually slower then molasses at times and used while on the go or when lacking any other usb ports to charge with since the current as far as USB 2.0 is lower while the newer 3.0 allows for six not four devices providing a boost there.

Those will be fine. More than fine.

I can't see where there would be any problem unless a detect did come up for some reason since once you have it plugged in the charging for the most part is automatic. The MVP will turn the charging process off once the max battery level is reached. Recently as I mentioned earlier I more or less solved the charging situation here fast enough where I can a cell phone and two batteries or mods being charged at the same time by going with the portable charger as well as just happening to spot the alarm clock one day with the twin ac outlets and usb port.

The portable charger is also charged up by way of a usb port as well since that is large capacity battery you can carry in a purse or coat pocket. One vendor has it the one I bought still marked down onsale for $90 off of the retail price at Amazon. It didn't take to grab it up for only $39.95 when another vendor has it marked way up at $173.40 above the MSRP! Amazon.com: Jackery® Giant+ Premium Portable Charger Aluminum 12000mAh Power Pack and External Battery Bank with Dual USB Port for Apple iPhone, iPad, Samsung Galaxy, Nexus, LG, HTC (Orange): Cell Phones & Accessories

Another listing has it even lower for $35.95 seen at Amazon.com: Jackery® Giant+ Premium Portable Charger Aluminum 12000mAh Power Pack and External Battery Bank with Dual USB Port for Apple iPhone 6 Plus, 6, 5S, 5C, 5, 4S, iPad, Air, Mini, Samsung Galaxy S5, S4, S3, Note, Nexus, LG, HTC. Portable Batte

The alarm clock I mentioned was priced for $44.95 at Amazon but found at Walmart for under $25. http://www.walmart.com/ip/Sharp-Alarm-with-USB-and-Outlets-Black/24225430

With either of those you won't have to worry about charging any ecig let alone the MVP. Cell phones draw more heavily on them. Walmart online at least also carries another portable charger for only $13 but can't say how good that one is as far as the quality. http://www.walmart.com/ip/12000mAh-...tery-Pack-Portable-USB-Charger-White/41475494

As for wall outlets with usb ports they have a number of them at their site to look over. http://www.walmart.com/search/?query=usb wall outlet&typeahead=usb wall outlet

These are just some ideas to pass along here for you or anyone else who may find one of these quite usefull. The only time I had any problem with one of these was with a 6 outlet model with surge protection where one of the two usb ports didn't work. http://www.walmart.com/ip/Belkin-Belkin-6-Outlet-Surge-Protector-with-2x-USB-Ports/29562457

The Amazon links are through smile.amazon since I support the Vape-A-Vet project where a small percentage is donated to the non profit group to help vets get into vaping. Just about of those are 5v 1A as far as being able to charge the devices like IPhones that draw more heaviily.

I PIF'd my 3 MVP2's after I got my first iStick (the "original" 20Watt)...they just felt like bricks!!!

IStick (just) came out with a 30Watt version. It's essentially the same small size that's so comfortable to hold. It has a Stainless-Steel threaded spring-loaded 510...and...they changed the "controversial" MEAN regulation to RMS.

10percentoff coupon lowers the price to $31.49

Eleaf iStick 30W Battery - Eciggity

This looks pretty sweet! Overall, I prefer the MVP 20 watt in my use case, but thats definitely a sweet deal. I dislike- to say the least- the connector on the iStick. They have solved that with this one, so thats not an issue. The 30watts is good for some I suppose, but im not really sure I need 30 watts. The Russian 91% doesnt have the width to use a coil that could take advantage of 30 watts, unless you go dual coil. I thought id be all about that, but honestly the 28 guage single coil works so well I have no real need to go dual coil (wastes more wire, harder to wick, etc)...

There is one thing I dislike about the iStick that isnt really its "fault." The fire button location. The Russian 91% air hole lines up perfectly with it which sucks- sometimes the 91% needs to be "burped" or leaks a little juice if left on its side for a long time. Eventually the iSticks button gets "sticky" and wants to stay on, not engage, etc.

For me, The "brick" and Tank like feel was and is a positive.

If I wanted something dainty I probably would not go for a box mod.

I carry my MVP20w around without having to adjust my pants.

Really is not that heavy.

Eric

Yup! I prefer the brick like feel when hanging around the house. I preferred the iStick on the go, but the MVP 20 watt isnt bad.

Been using the MVP 20watt full time now for the last few days and im really liking it. Nice fast warm up, long battery life, and good feel. I suppose the power hungry might want more, but its great for me!

I have read elsewhere that in VW mode the MVP automatically sets the Voltage for the detected coil. If this is true then I'm to understand that if I put a tank with a 2.1ohm coil on my MVP and set the VW to say 7.5W then I have no fear of ruining the coil? Or even if I set the VW to say, 9.5W then my coil will be safe because if the VW is too much the MVP will automatically adjust? Or is this incorrect? If so, please let me know.

Nope, if you set it at 9.5 then 9.5w is what you are going to get regardless of the topper you put on it. The "automatic" part comes in when you switch to a different resistance topper. The unit will "automatically" change the voltage so you get the same wattage out of the different resistance coil. My suggestion would be to just leave it on Voltage if that is what you are comfortable with. I have owned MVP's since before they offered VW and the only time I have ever put them in to VW is when I got them and made sure the feature worked properly. Since then they have never been put in to VW.

Thanks you Night Hawk...

I have been using a 5v 1ah cell phone charger to charge my mvp's for a couple of years now.

Well, I ended up with a pair of black Cloupor minis, a pair of ss Kayfun v4 clones and a vct 4... My wife decided she wanted a mini and a Kayfun too

I read 30 descriptions and not one made any mention of swapping RMS/MEAN

and you know if it happened - THEY'D BE SHOUTING IT FROM THE MOUNTAINTOPS

I'm still waiting for mine to arrive. But multiple "early adopters" (some even with oscilloscope tracings) of the 30Watt-iStick report that MEAN has, indeed, been replaced by RMS.

[sando7]

anyone hear yet about the price on the MVPV3?

 

[fishj]

Has anyone ever tried to sub ohm with his mvp 20 way? I have tried the Atlantis, Kanger Subtank, and .8 ohm Kanger coils and none of them fire? I finally was able to use a 1.0 Kanger coil in a Genitank. Nothing lower would work for me. Thanks.

 

[draconianchaos]

The MVP 2.0 can't subohm as the 20 watt just bumped the upper power limit it shouldn't be able to either.

it seems a bit peculiar, but what Innokin rates them at:

VV4 = 4A/15W/.8Ω
MVP 20W = 6A/20W/1.0Ω
MVP 3.0 = ?A/30W/.4Ω (not sure what the amps rating is)

Great ! I just skimmed around a bit, and seen no reference as such
but reading your links, peeps seem to think it is better (all that matters)

hope it works swell for ya…

Both of my MVP 20w fire at exactly .9 , no lower. While technically it is sub ohming, It is not what most consider sub ohming when they talk about it.
That is one reason I am awaiting the MVP 3.0.

I didn't see any pictures as proof or such, but after a thread search for 'scope' I saw this.
At least I haven't seen anyone trying to apply AC RMS calcs to DC PWM in a while
