And another exploding ecig

[Dennis]

As @gords1001 said, it is the "in the event of charger failure" that has to be taken into account re safety.

I know.
It's the way he said it - you'd think gords1001 woke up on the wrong side of the bed today..

I said something but it had already been said so I'm editing this to shut up instead.

 

[TomVa-ping]

Yet again it's the ecig fault ffs

Where is the charger that is supplied when bought and also does she not read up on things?

Human error yet again ducking it for us

Just to be clear.

Yes applying more than 4.25vdc can be bad for most li-ion/li-po cells (there are cells that charge to 4.35vdc max). However. You cannot just randomly apply any potential current you wish. All cells have a c rating, their maximum charge and discharge ratings are factors Of this c rating, so you will see maximum discharge 2c or 5c or in some lipo cases 25c or more. You will see maximum charge rate 1c or 5c etc. You shouls though, if you dont have access to the ratings, always assume charge at 1c discharge at 2c.

This is why people suggest sticking to a 500ma supply. It eliminates one of the charging state issues in the wvent of charger failure. Yes you can still apply excessive voltage, that will make the cell unstable, but excessive current will make the cell fucking hot and that is the big concern here.

So could the idiots that keep saying a two amp power supply feeding a little puny cell is fine please fuck off till they understand what they are talking about fully? Kthanks

nobody said it was fine to charge a puny cell at 2 amps, you abrupt, arrogant prick. who the fuck are you to start calling people idiots just because you've fabricated an argument in your head. i said it was fine to plug an ego charger that was regulated to the correct voltage and current into a 2 amp charger. big difference. instead of getting your knickers in a twist and referring to people as an idiot when someone plugs an e-cig into the wrong charger, why not lobby e cig vendors to place warnings on non regulated or battery specific chargers or to include better quality chargers or even just pass on correct information instead of being a raging bell end and acting like the whole future of vaping is resting on whether they blow their battery up or not. if i didn't enjoy vaping as much i'd vote against it just to piss off people like you.

You are missing the point !

It is fine up to the point that it remains regulated once that circuit goes tits up which it can and will with repeated use you are then pushing 2a down an eGo battery only supposed to be taking 450ma.

It will still eventually vent if sending 500ma if the regulation fails but it will take a lot longer as opposed to 2a.

i'm not missing the point at all, you just don't have a clue what you're on about. how will repeatedly using an ego charger on a power supply that CAN supply 2amps should it be connected to something that actually draws 2 amps. you'd rather blame anything but the actual problem. if it goes tits up it is either a defective or shit quality charger and if it is the correct charger for the battery and it has not been misused in any way (connecting to a 2 amp supply isn't misusing it before you start) it is the fault of the vendor or the manufacturer.

if i'm to use your logic, should i stop plugging my nitecore charger into the mains as it only requires 12v and not 230v? should i source a car battery and keep it specially for the nitecore to charge 18650's and 18350's so i don't plug it into the wall and risk having to make the inbuilt step down circuitry do it's job? surely if i keep using it as it's been designed to be used then it will eventually give out and burn my house down according to your logic? and when this car battery is flat i should put it in a car to have the alternator charge it rather that plug it into a mains charger as that will be also 230v and the car battery only needs 12? how about solar power, or windmills? should i rig it up to my bike so i can pedal and charge it? i think you need to give your head a shake...

Your TV / Radio will run on 110V but you won't switch it on using that setting when wired to 240V will you ? I don't know maybe you're the person that would ?
Your Nitecore charges at 500ma and that's designed for bigger cells so why the hell would you want to charge an ego with 2a

Just putting it in to perspective.

Exactly. Just because a wall plug CAN supply up to 2A doesn't mean it WILL force those 2A into anything that's connected to it. It's up to the device connected (the regulated charger) to draw whatever Amps it needs from it. Current is highest when first connected then becomes lesser and lesser as the battery tops up (battery voltage increases) and eventually becomes a maintaining trickle at the time the led goes green. Should the regulated charger go tits up, then it will continue charging the battery without the led going green (notifying you) but the current will still be lowish because the battery is back up to 4.x V and fighting the voltage applied by it's own counter voltage. Exception to this is the battery itself going bad and continuously drawing a high current from the charger but no higher than it can provide regardless of how many Amps the wall plug CAN produce, but that could happen in any charger, which is why we shouldn't leave any unattended. For example, it was mentioned that a single discharged 18650 battery in a single bay on a nitecore i4 charger can draw UP TO 750mA (not mAh). If I were to remove the battery and shortout the terminals the current wouldn't go higher than 750mA because that's the highest current this charger can send to a single battery/bay regardless of of it being connected to a 240V wall socket. (although I'm sure the i4 would detect this and switch off the bay).

You're talking about plugging a device that uses an unregulated 110V mains input into an unregulated 240V mains?
Depends - if the internal power supply in the TV is the traditional magnetic transformer feeding a traditional diode rectifier bridge, capacitors, Zener diodes, etc, than these would be receiving double the transformer's output voltage - probably frying the TV's power supply and/or electronics. Modern Power Supplies used in computers, battery chargers, etc are multi-voltage.

Let's keep it simple -
If you screw a 500W/240V bulb into a 240V socket it will DRAW 2.08A
if you screw a 20W/240V bulb into a 240V socket it will DRAW 0.08A
if you screw a 5W/240V bulb into a 240V socket it will DRAW 0.02A

Sound familiar? [emoji12]

And I'm the arrogant one?

Do what you like, clearly there's no way you are going to grasp the idea of damage limitation or risk reduction, its far easier to throw the toys out of the pram and spit vitriol like a spoilt child.

I would attempt to explain the idea, but Danny K already has and you seem more interested in throwing insults than considering another point of view.
