Question About Charging My Mod

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  

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)  

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..  

my vaporizer has a battery of 2800 to
was charging on a 2a 5v charger
carried about 3 full charges.
so the manufacturer recommends a 1 to 5 v charger
tripled charging time instead of decreasing.
do I continue with 2a instead of 1 a?
can give problem ???
thanks  

I have an orbit cannon vape pen. I believe it's 510 style.

I bought it 5 months ago. I just got around to using it. You press the button 5 times, and it turns on, press it 5 more times and it shuts off. The light also indicates the battery voltage. It turns white when fully charged, and then blue, and then red when it's almost dead. There is also a light on the charger that is red while it's charging and then it's supposed to turn green when it's done charging.

Well, the e cig battery light stays white for a short while, and then turns blue. It used to stay white longer. It's like after a short bit of usage, it goes blue. The red light on the charger also never turns green no matter how long it stays plugged in.

The e cig stayed in the box, and the battery was depleted. I picked it up a few days ago and put it on the charger to start using it and noticed this.

Does it sound like the battery is messed up? Last night I charged it 3 hours and the red light on the charger never turned green so I unplugged it. The light on the battery was white. Today I went to use it, and the light was blue - I never used it and the e cig itself was turned off.  

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.  

Can I use an external battery pack to charge an IPV Mini?

I have a 10,000mAh external battery to charge my cell phone (Note 4, with a 3500mAh battery), which has 2 options for charging: 1.5v=1A and 2.5v=2.1A.

Is it recommended? Is it safe? Are there any precautions I need to take if I use the battery pack?

I haven't gotten around to getting an extra 18650 battery (and charger) for the IPV Mini. I've finally realized that it takes maybe 2-3 hours to charge the battery via the USB cable. But the one battery doesn't quite last me all day, depending on how heavy I'm using the Mini.

I usually carry a Volcano Inferno once the Mini dies, but the Volcano really sucks in comparison to the Mini. I'd love to be able to charge the Mini while I'm out and about.

I've added a pic of the external battery for specific information.


Thanks for all your help.  

I'm charging a purple EFEST IMR battery in an XTAR LI-ION battery charger and I wanted to make sure Efest IMR purple is actually covered under LI-ION charging.. I can upload pictures in a second but I've been charging the battery for about an hour and this is my first electrical mod so I am trying to make sure, thank you. It says it is for rechargeable Li-ion batteries only but so far the battery is not hot or any problems  

Hello Guys,
I noticed that there are a lot of people who are used to charge electric equipment in Inappropriate ways.

Don't know how many vapers use the charging cable to connect your e-cig device or charger first and then plug the adaptor to the power supply end.
Taking phones as example, if you firstly connect your phone and then plug your adaptor in the socket, there will be a huge voltage assault to the phones which is bad for the life and performance of your phones. Otherwise is the adaptor you are using is DC adaptor, by connect the adaptor to socket first, the high AC volatle can be converted to low safe voltage such as 5V, 12V, in this way, the assault to your devices will be reduced in a large degree.

This is all the same for charging e-cigs, and batteries.
 

In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A); in USB 3.0, it moves up to 900mA (0.9A). The charging downstream and dedicated charging ports provide up to 1500mA (1.5A). USB 3.1 bumps throughput to 10Gbps in what is called SuperSpeed+ mode, bringing it roughly equivalent with first-generation Thunderbolt. It also supports power draw of 1.5A and 3A over the 5V bus.
