The best way to charge you e-cig and batteries

[Mangguo]

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.

Mangguo, can't say that you're wrong or right, but citations are always welcome. A lot of us appreciate details, and as a geek/tech nerd, the more information, the better.

Can't be wrong but, as an electronics specialist, I can't say this explanation is 100% right on either. There could also be a remanent charge in the charger (which can screw with the electronics) and plugging a charger to the equipment before plugging it into the wall also means there is a small discharge current from your equipment to the adapter.

Don't mind the details, the part that is 100% right is: first plug in the wall adapter, then the cable (if applicable), then your equipment. Do that in the reverse order once the battery is full. That is THE rule in electronics on how to deal with wall adapters.

Thanks for bringing this up.

This is incorrect. At least, with any power supply/charger made in the last dozen years or so. For the example of cell phone charger: It has to ramp up to 5.0v, so it may (or may not actually) supply less than 5.0v until it is ramped up. Switching supplies don't take long to ramp up to the correct voltage, but they do have to ramp up before they will deliver that to the connected device.

There is no difference that could cause overload on the device end if the device is attached before power is applied to the switch or if the switch is powered before a device is attached. Either way, the caps have to fill... either the capacitors are already full when you plug in the device or they have yet to fill when you plug in to the wall.

[SIMPLE VERSION]:
Just follow the right order of things: plug from the wall to the device and unplug from the device to the wall.

[COMPLICATED VERSION]:
All power supplies have always needed to get the caps filled to be up to output voltage. Recent power supplies use smaller caps, but more complicated power switching. No matter how they work, you are draining your equipment if they're not plugged in. Ramping time should take much less time than you need to connect the rest of the equipment to the power supply. I think this is all wayyyyy over most vapers heads, though. Not bashing on you mate, just wanting to keep people interested so they can learn and follow good habits. Simple rules are easier to remember than physics for most people. I'm also simplifying my own post here:

Sorry, I trried to find eveidence online but failed. This is a conclusion made by myself from what I experienced.

Thank you for your detailed explanation.

Simple rule of design: Never trust the user. In this case, never trust the user to plug this end in before the other end. These chargers are designed in such a way that they just don't care what order you choose to do things in.

I'm not trying to be ornery. There is just no difference to the device in what order one chooses to plug in.

It's just a transformer followed by a rectifier and almost certainly a regulator in the case of 3.7v and 5.0v applications. If you plug the charger without the device, it's just an open-ended transformer. The only current drawn is the one from the ion losses and the creation of the field within the transformer, and that's not even enough to be called nominal. Plugging your device in at that point is just like switching a switch on. As for the other way around, the transformer will be ramping up because of the inductor. And, in the case of all of the chargers I've had apart that handle batteries the type my e-cigs use, there are capacitors to fill. There just isn't a difference on the device end if the switch is open while the voltage ramps up or if the switch is open after it's already ramped up.... other than a tiny little difference in time between making the connection and electrons flowing.... and I'd actually have to go across the street to the lab to get them to figure out exactly how much time because it is surely less than a millisecond.

The USB-510 chargers don't activate until everything is together. Or sometimes after you plug things together, unscrew and rescrew the battery twice and then wiggle it a bit ....

 

[Alien Traveler]

Simple: in manuals for chargers there are no advice on order of plugging things in. So, it does not matter. Or almost does not matter.

 

[bluecat]

Doesn't matter. Used to, but hey we can run a car off batteries now. Of course depends on what the wart is, most are mini transformers.

Actually, the best way to charge your batteries is to hook your charger up to a treadmill and then start running.

How many would have charged batteries using this method? It would be the death of vaping. Hard to drip while running.

 

[HauntedMyst]

If it was their only choice, lots would! And they would lose weight, be healthier and feel better. My wisdom and ideas help mankind.

LOL, of course, there won't be much difference about which order you plug things in if there is no long delay (or more than minutes and provided the device is well built enough and had no defects). And you reminded me of a quote I use a lot: "Make it idiot proof and they'll make a better idiot"

Look who's talking!

The answer is 42.

 

[Robert Cromwell]

42 is the answer to everything. Perhaps the perfect wattage?

Darn.... I have to wait for the DNA42 now?

EDIT: I just realized I mostly vape at 4.2 volts, my car's plate number starts with D42 and I'm turning 42 next year... Ask me any question and I'll answer it 16 months from now

 

[Robert Cromwell]

Naah the Istick 50 will do fine for you. 42 is all you need.

I had a old ford , I had to pump the gas 3 times wiggle the key and pat the dash board lovingly as I turned the ignition and say come on baby and it would start most times.

Lots of little rituals seem to make us feel better and we swear buy them but lots have no mechanical practicality what so ever.
