USB Charging Box Mods

@Scuba Vaper It depends on WHICH battery you look at. Efest only re-warp other companies batteries and sell as their own. Unfortunately they seem to change the original companies battery specs to suit themselves. Also if the supply is down they will re-wrap a different battery and sell it as the same. Basically it is a pot luck with Efedst.

 

Tienga's a retailer, he doesn't make them, well as far as I know he doesn't ... I don't think he'd knowingly sell anything "fake" either, seemed honest to me.

So question again - who makes efest batteries ? Do they have their own factory ? Or do they rewrap other's "a" or "b" grade batteries ?

 

Google it dude

 

Pot luck, I don't think there's much to add really, could be that you're getting a top of the line battery, or could be efest wanted to make more profit that month, and are shipping LG's rejects re wrapped and overstated amps and Mah ...

I dunno ... But what I do know is that reputable firms original bats are much more likely to be "safe", and don't actually cost that much more, and not that much less amps or Mah ...

Thanks, but I won't, just now, as I don't need any batteries.

My point is that you don't know who made your batteries, whether they are rewraps or not, and whether they are "a", "b" or "z" grade batteries.

So please can you google "recommended vaping batteries" (which is what I did, before buying my latest Sony VTC5s) ... LG, Samsung, Panasonic and Sony (and a couple of others?) will appear on many lists, and whilst they can still be used and abused by morons, they are likely safer and last longer, than any "generic" brand name ...

Ps, within that, I don't know if efest, are good or not. I only looked at them briefly when I was looking into 18350s, because the "big" names don't seem to make them.

It's entirely possible that your efest bats are great john, I just don't know, and was my choice to buy different brand. This was after research and a long thread here with @Siam Diesel , which I think you participated in.

 

Do not hook up 12v to anything designed for 5v! It will straight pop a fuse (if you're lucky) and/or fry the circuitry of the mod.

USB cable is specified for 5v and only 5v.

 

Oh I thought we were still talking about charging through mods. My bad!

I agree that no change would occur, the charger still outputs 4.2V @ 1A current regardless if 5V or 12V supply is given to it.

 

Since Micky and Big have HG2's in stock, I guess I'll get a few of them. No problems with the Efests, and for low wattage MTL I'm not worried, but I won't knowingly deal with a dishonest company. Maybe the young ladies in the photos on their home page are really re wrapped Sony retirees.

 

I have been vaping and charging my Efests battery everyday for the last two months, but it takes longer time to charge them up, and they don't last as long as they did.. Efests battery all I got so I can't compare it with another brand...

Even if they are rewraps or not, They are still Good battery's! I just fukd mine up with some ruff handling when I was using the elfest charger and not the USB. Anyways thanks again..

 

Batteries will wear out over time, it's to be expected. My sonys seem to take longer to charge and less vaping time. However for me personally, only a subjective measure, as I change watts, coils etc frequently and recently using dual coil setup which uses more electrons.

Ruff handling you can fix, by using care. That's user error, not a technical problem anyone here can fix or help you with.

Cables getting mixed up you can fix by labelling your cables. As said already charging only cables are usually thinner. Better quality charging cables, and cables with data are generally thicker.

Short lived batteries you can fix by buying better batteries.

If you want to charge batteries faster, then don't charge on USB. My nitecore D4 has built in adapter mains to charging voltage, and will charge at 3/4 amp on lion batteries (split across batteries being charged). My xtar needs an external 5v adapter and reckons it'll charge up to 1A (not sure, but I think this is per battery, so needs 2A 5V supply)

I don't know what charger is included in the mods, I'd suspect 0.5 amp, as that's max draw on a USB2 port.

Also, charging on USB depends on a) what the mod will use amp wise and b) what the supply will provide amp wise.

And actually with 18650s just buy more cells, then there isn't really a problem with how long they take to charge. If you have 4 batteries already charged, then just charge each one as it goes flat and rotate them. And so on ...

 

I believe the OP is using subox and eVic mini, if that helps ...

As regards the governing factor, that's what I said wasn't it ... Obviously you can't charge @ 1A off a 250ma supply ... But with OP asking about charging lions at 12V, for faster charging, I can see why you clarified that !
