The Possibility Of An Ego Type Battery Charger Mod

I ordered two of these batteries from FastTech. The cheap price and high capacity (without having a mod or some awkward huge battery) attracted me to them. Some two weeks later they show up...

I have two Puff King chargers that came with starter kits we bought at a B&M store. We've been using them with Tripl3 eGo batteries, one Puff King battery (and another Puff King battery, which was taken back and exchanged for another eGo-T battery, which broke), and so far no problems screwing any batteries in. These two from FT show up however and neither will screw into one Puff King charger, but they both did into the other (same charger, down to the model number and everything). Now, one battery from FT still screws in, but the other doesn't.

I took the non screwing in battery to a local B&M store and the guy there was able to screw it into one of their chargers. He handed it to me, and I unscrewed it, screwed it back in, unscrewed it again, and then neither of us could screw it in again. Now I have one battery from FT that will screw into one of my chargers, but not the other. The other battery will charge, but it has to just like sit in the charger and hope the connection stays okay for it to charge. I still have no problems screwing any of my other batteries into either charger, just these ones from FT. Also, it's worth mentioning that the FT batteries never seemed to screw in right... it always felt weird and finicky getting it to go in.

What's up with these batteries? They claim to be eGo/510 threaded, just like my other batteries. They look just like my other batteries too, except they won't screw in right...  

I've been charging my 18650 batteries on a Nitecore charger but having to unscrew my Smok XPRO m65 is a real pain so thought I may as well make use of the USB port and charge the battery while it's still in the mod.
But I've been hearing a few horror stories of other mods such as the clouper, apparently its not safe to charger using the USB port

I'd really appreciate it if anyone can help inform me if I'd be able to use my phone charging adaptor with my mod.

The input and output specs of my phone charger and mod input are in the attached pics.

Cheers everyone  

It's quite expensive and I can charge it with a better charger that will prolong it's usability then I'm all for it. It doesn't matter how long it takes to charge, because I have others I can use while it gets charged. The manual says not to use chargers that didn't come with it but I want to find a way to improve their lifespan anyways because their lifespans are short & they're very expensive.

Apollo Valiant VV & VW 1300mah Battery is my battery's link. If there are any better batteries that are better I may be interested in upgrading, I strongly prefer the stick kind like this, but if they are super awesome they don't have to be but I don't like the idea of having to build a battery myself.  

I bought my Sigelei 100w Plus a few days back and ordered 2 Sony VTC4's on my same order (I'm confident they're legitimate, I've bought some before) to be able to marry them together and use them with my Sigelei. Upon receiving the batteries, I labelled one A, and one B and put them into my charger at the same time (charger was off, put both in and turned it on), one battery is slightly more charged than the other (it's 2/3 bars, while the other is still 1/3). I'm a bit worried about using married batteries, I understand rotating A and B in my Sigelei and charger but will they be the same charge when they're done? They're new batteries and they both went on at the same time yet one of them is charging a little bit faster.

When both of the batteries are fully charged, will they be safe to use and cycle accordingly? I heard about if one battery has even a tiny bit less, the batteries will take an uneven load and it will make it risky. How do I ensure that these batteries remain married?  

Hi
I just got a Xtar VC2s charger for my 21700 batteries (Samsung 40T).
Chose that charger also because it "charges at safe low current".

When it charges 2 batteries, it's at about 1000 mAh for each battery. All good.
But when charging only one battery, it charges it at 2000 mAh. Hmm?

I assume 2000 mAh is still "safe".. But won't that reduce lifespan on the battery?

The charger manual says "when the power supply is insufficient, the charger will reduce the charge current correspondingly".
So maybe I should get a usb power supply with like 1000 mAh output?

I will only be charging one battery at a time, and prefer charging slowly if that gives more safety and lifespan.

But I don't know if charging at 2000 mAh is really an issue..  

So i just got the nitecore 1a charger in the mail today for my 18650. Previously i was using the usb charger to charge it on my ipv mini 2 but i haven't tried the nitecore yet. about how long would it take to charge this battery on my nitecore?  

I got EVOD battery and aspire charger.

Specs of EVOD charger has 400mA output and aspire charger 420mA output. It's the only difference

Can I charge EVOD battery with Aspire charger safely?

My EVOD charger is an hour away.  

I just got a nitecore i2 charger always just use the charger on my mod but it's starting to get a tad wiggle to it so figured I'd buy decent charger just wondering how long to charge and is it supposed to get a little warm?  

Just watched a news video... "Vape pen charger explosion"
Vape pen charger explosion causes thousands of dollars worth of damage to California woman's home
The lady was charging a vape pen and the charger "explodes" causing a nearby paint can to shoot up into the ceiling. The fire dept guy says "those lithium ion batteries..." and so on. Now wait just a minute! Technically, it wasn't a "vape charger" and they showed the vape pen looked fine. Pens don't come with a charger, just a USB cord, so it was just a universal USB charger (like for phones, ect) and the pen battery didn't explode. Also, why did she have a paint can sitting next to it? Did she leave the vape pen on (might not matter)? Was the USB cord damaged (short)? Pens use a LiPo battery not Lithium Ion. I know I'm nitpicking, but all people will really "hear" is vape pen explodes... nobody really thinks things out. Could this have happened anyway while charging a phone or something else? Right after watching this, I see an article in the local paper telling people to stop vaping immediately because of the recent events (and they don't mention ANYTHING about the real cause!) Final thought: there was also a water bottle next to where the charger was... maybe she spilled water on the charger? I'm like Peter Falk in the old TV show Columbo... "but what got me thinking was..." Maybe I overthink things, but at least I do think (and ask questions)  

So last night I guess I was more tired than I anticipated and forgot to unplug my charger before knocking out. I was charging a 18350 battery. As soon as I woke up I remembered and immediately unplugged the charger. I left the battery sitting all day and just checked it on my multimeter and it reads 4.18 volts. I also checked it on my sigelei and it read 4.2 volts. I am th overly cautious type though so I just wanted to ask you guys if you think the battery is still safe or if I should properly dispose of it.
