Charging 21700 Battery At 2000 Mah

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'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  

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  

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'm using Samsung 21700 T40 batteries.
Trying to figure out..
Is it best to charge a battery when it's discharged or nearly discharged?

I like to keep things simple with a routine of charging once a day, but then the battery will be set to charge even when there's 15-30% power left.

Is that bad for the battery?  

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 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?  

So I have a SMOK M80 XPRO PLUS that I got a few days ago. Just wondering is it safe to use a phone charger to plug it into the USB port on the bottom?

My uncle, who I stay with, watched some news article about someone's battery blowing up in their apartment and just wants to make sure I am charging this thing safely. I have been using my phone charger up to this point, with no issues.

Any feedback would be greatly appreciated! Thanks!  

I just got an istick 30w the other day from a local tobacco store. I bought an istick 30w for $45 which isn't too bad, I'm having problems with it not charging to full. I am using a 1a rated charger and it is supposed to charge to full in exactly 2.5 hours with a dead battery. I cannot get it to charge above about 75-80%, no matter what I do. As of now it's been on the charger for 2 hours and 38 minutes and is at about 80%, and is showing no sign of continuing to charge.

When I leave the device on overnight, I will wake up and it will be at around 65%, and it would have just stopped charging. I don't understand.
