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.

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
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 bought a brand new freemax twister 80W kit and when i connect it to the charging port the blue ligt flashes then theres no light to show that it is charging, what may the problem be???
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.
I purchased the Geek Vape Aegis Boost a few weeks back. This is probably the 20th vape device that has stopped working on me. The micro usb port no longer takes a charge and I was gentle with it when charging it. I'm going to stick to vapes that use usb c charging from now on.
Does anyone have a recommendation for a vape decice that has a large enough battery for a full day of heavy vaping, uses usb c and had a large tank that will also hold enough juice for the day? Draw activation would be nice but it's not necessary. I also need something that is mouth to lung because I get a sore throat easily from vaping. Also, I'd much prefer the battery to be integrated in the device as opposed to having to put the battery in. There are too many options on the market and I can't decide which one to get so I would appreciate any help. Thanks so much in advance.
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
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..
how many time do you touch the device to check if it is hot while you are charging it?
Mine charges at arms length so I find myself putting my hand on it every 20ish minutes or so
I found using the stock 1 amp plug it got 3-5° warmer when charging, with a 500milliamp one, no difference at all
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
I have an Egrip. Long story short I think I got water in the charging port. It's not working. Did I ruin it or might it dry out and work later?
