Battery Charging Question

Am I correct that you can charge a mod that accepts a mini USB with a Samsung phone charger? I think I read that some place, but would like confirmation.

 

Yes you are right.

 

VERY cool...thanks!

 

Just be aware that some of the modern Samsung phone and tablet chargers can put out 2+ amps. I wouldn't subject a small battery to that on a daily basis. All depends what charger you have and what your charging but yes you can.

 

Nothing to worry about there, amps are drawn, not pushed. A device will only draw as much as it can handle. Voltage is what is pushed, but voltage will be the same for all USB devices.

 

Disagree with you there. You can charge a battery at 1A, 2A, 50A. A battery will take as many amps as you give it.

 

I just want to add that these phone "chargers" is in fact not charges but a power supply unit, the phone has the charger build in so to say, same goes for alot of the vaping stuff you charge with usb(not ego's, here the charger is in the thing you put on the 510 connection)

The only thing that could happen is too small amps, i seen cheap 7/11 usb "charger" as low as 500 mah wich would take a long time to charge or fry the power supply(usb "charger") maybe both.

 

We are not talking about charging a batt. here, we talking about powering a charging chip that will charge a batt.

 

The OP didn't specify. I do know DNA style mods have their own charging board.

 

I think thay all have if thay have a usb charge option, you cant charge a batt. with constant 5 volts without it gives problems.

 

Maybe I should clarify, I was talking about USB charging, not directly charging batteries. Yes, it is possible to draw more amperage when you are charging something like an 18650, because the battery doesn't contain any circuitry. The charger is choking the amperage down to the required level. If you get plumbing, amperage is the width of the pipe, voltage is the pressure of the water. When you partially close a valve, you restrict the flow (amperage) but the pressure (voltage) stays the same. This is what the charger is controlling.

USB follows a specification. USB hosts will only put out 5v (to simplify, some can put out more but communication needs to take place first). To charge something via USB, the device needs circuitry to manage that power. For the eGo screw-on chargers, the circuit board is in the little bit that you screw the eGo into. For something like an iTaste VV or my Vaporshark, that board is inside the device. It is that board that takes the supplied 5v and uses it to charge the battery, doing stuff like monitoring battery voltage and cutting off power when it is full.

Normally, a USB device will only draw 500mah (.5 amps) from the host. To draw more, the device has to signal to the host that it is capable of drawing a higher amperage. There was previously no standard on this, which is one of the reason iPads need a special charger. They send the signals differently. Now, however, there is a standard, which is why just about any tablet will work on the universal 2.1a chargers. This is also the reason you can't plug an old iPhone that expects 500mah into a 2.1a charger and have it charge 4x as fast. It just doesn't work.

On a normal battery (non USB, back to the 18650 example), as I said before, there is no circuitry. Just like you can draw too much too fast (short circuit) you can charge too fast and damage the battery. Batteries have both a discharge amp rating and a charging amp rating, so most of the good chargers out there have a selectable amp limit. You're right, if you didn't have this function, the battery would just pull as much as it could until something fried.

 

Going to do a test. Dam these little VV V3 have a nice battery life when all you want to do is drain them

 

Specifically, I'm looking at this for both charging and pass through. Most likely on a Innokin iTaste VV V3.0. It interests me, because I already have a Samsung at my computer desk, so I would not have to add more wire to the mix. In addition, the Innokin iTaste VV V3.0 does not come with a wall mount, so the option to use the phone charger is attractive, as I don't have to deal with buying/adding a wall mount. I do have a wall mount that came with the eGo-C, but not sure if that is compatible. Plus, I might not want to tie that one up. Just sorting out what my options are.

 

Again, it'll work fine for both.

 

COOL! Thanks very much!
