The Fist Pack/Mobile Power Univeral Charger

[dedmonwakin]

I was thinking quick-set magic putty. But a blob of hot glue would do the trick

I have Magic Sculp 2 compound epoxy putty, (one of the mediums I sculpt with) which has a working time of 3 hours and takes 24 hours to cure.

The 2 compound Epoxy putty (plumbers putty) mentioned in the video has a working time of 3 minutes and cures in 1 hour.

My only concern of using hot glue to attach a cap to a button, is that it flows, and may get into the switch or atleast jam it up.

I'm looking into different switches that allow for greater amperage and possibly a better fit, such as mini reed switches or momentary rocker switches.

Not a vast array of miniature switches on the market for DIY consumers.

If you think you have enough space (should be) I could post a touch switch - then just a chrome contact is all that is required; and lasts for ever with near zero resistance.

The unit has a master on/off ?

 

[dedmonwakin]

BTW, I searched n google using image search, for anything that might match or better this, but found nothing.

Is it charged now and up and running ??

Yep, all is well, been vaping on it since it fully charged at 1:30 today. So, eleven hours with 3 status lights showing....I can live with that.

I did notice, that the 4th light, does not stay on long at all. After 30 or so minutes of use, it stays at a steady 3 lights all day. Which is pretty much the same when I use the USB out, but drainage occurs much faster charging a device.

Was curious about the dual atomizer mod made by another member and reviewed by Igetcha. Thought I would test a dual atty mod myself, by hooking up my passthru to this mod and vaping both from this pack and out of the USB out.

I love throat hits and all, but it's like smoking a cigar and inhaling. Not for me.

So, it's cool to know if my wife wanted to vape, and if I were tolerating enough to have a cord dangle from my pack, she could use a passthru from my pack while I vape at the same time.

Like a mini, hookah

Unfortunately no. This is what I have yet to incorporate. There is room for a switch, but....I would really like to keep the original case in tact as much as possible, so I've been delaying this.

But, yes...I would love to see how to make a touch switch, provided you make the directions easy enough for electronically inclined people.

Ok, will try to get a touch switch ready soon.

Re 3 of 4 lights - the vape would surely still be better than it was on the usb out because though the voltage has dropped the current is not limited (the voltage at the atty would actually be higher than on usb).

didnt see the double atty mod review you mention, though i did see one such by the australian guy.

personally i think double attys rock - the much better way to use extra power than just upping the voltage! All those people building 6v+ mods would do better to build double atty mods at ~4v

Oh yeah, I agree. Although I do find having two carts in my mouth a little awkward. Also, it's very difficult to get a tight seal around 2 carts, so drag time is delayed, but for the better. If I were able to take a full drag that I would at a single one, I'd have to follow it up with ice cubes.

But you are correct. The passthru out of the usb out, had delayed heat compared to the atty ran direct to the capacitor. Took a couple drags more to get it to catch up in almost equal vapor to the dedicated atty connector.

Attys use about 5w but 2w is sufficient - except for one thing, heat up time. Hence temp control can achieve fast heat up then limit the wasted power; user experience at least the same (minus burnt tastes), battery lasts longer.

The double atty paradigm is best because it matches juice flow with heat transfer in a way that a simple higher voltage mod cannot.

One can join the mouthieces easy enough, but there is still need to fill two carts, drop into two attys.

When all these things come together, we will have our nirvana:

dual atty (or equivalent; beefier atty design)
automatic juice flow from large reservoir
temperature control
usb charging/passthrough

Some other useful features include:

touch switch /push atty switch
assisted draw ('fan')

We need a device that can more than satisy, and can be adjusted
without needing to fiddle with all the time
big vape, no burning

this is the goal ...

Do you think there is a way to make the usb out amperage higher by removing something and still keep it at 5v?

My ipod charger in the video is 5v 1amp out. Doesn't out perform this pack in terms of mAh, but the heat and vapor production still is noticeably better out of the white ipod charger.

The battery with in it is a 3.7 single cell li-po, stepped up to 5v. I suppose that being a li-po makes a difference?

Push atty, I was thinking that I could do that with this mod the other day. I don't see why I cant push the battery back a bit by removing one of the tabs that holds the negative back side in place. All that is really keeping the battery in place is the tabs that its soldered to (which has much room for play) and a double sided sponge adhesive on the battery.

You say attys use 5watts? This pack at usb out puts out 8.1 watts.

No, not easily possible in such a small device; in any conversion power can only be lost. The circuitry could be improved but not a simple change.

The white unit can supply more power, but it is bigger. The circuitry is better (as well as the battery).

The black unit outputs 2.5w from the usb. Can output the req'd 5W from the battery itself. The white unit could feasibly output a bit more than 5w because the voltage is higher and the current less limited (perhaps 20% more; but because juice flow cannot necessarily increase to match, I would forget the white unit).

ps: though potentially could be better, typical voltage step up converters are around 70% effiecient.

 

[dedmonwakin]

Dang, oh well. It was a thought. Plus, it may just seem better because I'm using an RN4081 atomizer. I assume the smaller the atty, the better the TH and Vapor production is from the very beginning of use. At Least, this has been a noticeable difference to me, which is why I'm not that fond of the 901.

It seems the 901 can produce vapor much longer than the 4081 because of its size and the double wrap of mesh around the ceramic insulator. This comparison is by drip method.

 

[kinabaloo]

Think of a simple transformer with coils around a core. The voltage out depends only on the ratio of turns. But the efficient/max current/power transfer depends on the number of turns, quality of the wire and the core. So yes, it could be better but only by being made better; it's not a simple matter of removing something.

But by eliminating the step-up conversion, one gets more power out.

grats Dedmonwakin for your excelent mod , its preety nice looking and the battery life its outrageous , what can i desire more , still i got one question , I am surely going to buy that power pack and wanted to know if the mod is available for me as i am a novice at modding and would really like to mod this thing up . Would you mind doing a step by step guide? i would relly enjoy that.Thank's in advance

Yes, I'll be doing a step by step. Just working out some bugs, if there are any. It'll most likely be photos over video tutorial, haven't decided just yet.

 

[freddo]

waiting patiently for the build guide This is great, good find!!

 

[Nforcer]

Thank you mate , i really apreciate that .

 

[dedmonwakin]

I may also look into this battery pack. This has great potential too.

May not be as sleek, but it allows for easy removal of the 18650 battery, which means you can have multiple batteries on hand...not that almost a few days worth of vaping isn't enough on one battery, but who could ever have enough?

2200mAh Universal Portable Power Pack For Mobile - Black - GBP £13.00 : neTimes.com

The flashlight (torch adaptor) might be able to replace and tap into it. Making the atty connector totally removable, eliminating any need for a on/off switch.

Only thing I'm curious about, is it possible to both charge and supply power through one output? I don't see or read a secondary input for charging in the description.

So, if there is only one input/output-it won't be possible to vape with while charging.

 

[kinabaloo]

Quite like it.

Simple, clean look.

One connector for in and out. Autoswitched or with diodes or just circuits kick in because a voltage is applied or a load connected.

LMAO! Also found a site, that apparently isn't selling just yet.,...http://www.digipowersolutions.com/store/product_info.php/cPath/254/products_id/688

wow dedmon....you make some amazing finds! Do you spend your days searching the internet??

I rather like the idea of the usb-connected torch on this unit! Get a few of those and convert them to an atomizer connector of your choice and you'll be able to vape any e-cig that catches your fancy at that moment. Brings a whole new concept to "plug and play"!

Unfortunately, my computer is next to my workstation...so yes
That's exactly what I was thinking, aside from being able to exchange the battery out. I suppose vaping while charging wouldn't be that necessary since one has now gained the ability to change out the battery.

I'm just wondering if I could open it up with the case still intact. I see no screws, looks fairly seamless. And the flashlight fitting, looks somewhat larger than the case, but not by much.

To me, modding an already existing mobile battery pack makes far more sense, provided it is cheap,(in cost) determined safe (PCB) and enough room for modding. Beats having to build from the ground up, not to mention all the added features of the existing battery pack,....makes me happy.

Although, building from the ground up is satisfying, I'm just not educated enough to make it as advanced as I would like in techno features.

Wish I had seen this on dealextreme while placing my orders for the blue mobile power universal battery charger. http://www.dealextreme.com/details.dx/sku.18883
