USB cable question - any definitive answer on this ?

[CeciliaElec]

Hi

New member, just got the joyetech eroll, very happy with it so far!

I've searched the forums, and there seems to be a thread or two about USB cables, which can be used etc.

The one specific thread I found on this gives user opinions that any cable can be used.

However, the eroll manual strongly highlights to only use the original usb cable that came with the product, or serious damage may occur.

I've heard similar before - i.e. Samsung customer service told me that (for one of their cameras), charging via a Samsung mobile phone charger was fine, charging via laptop USB port was fine, however the original cable HAD to be used.

Can anyone with expertise in the area give a definitive answer on this ?

I've tried to stick to manufacturers instructions (for almost any product from any manufacturer, they emphasise to use original charging cable only), but occasionnaly mixed & matched with no apparent damage.

Are manufacturers just protecting themselves ? Isn't USB supposed to be a STANDARD, i.e. all the same ?

Hoping for a referenced, expertise reply

Thank you very much for your help!

Cecilia

When it comes to charging e-cig batteries ALWAYS follow the manufacturers recommendations. If you need to replace it make sure you replace it with a charger with the same specifications.

The majority of problems with regards to e-cigs and fires in the home are from someone using the WRONG charger.

Its no so much the usb cable itself. More the adapters people use to plug them into the wall/cig lighter etc... On those adapter will be the input and output info for it. Some have an output of 3.7v and 500mah which is the same that a USB 2.0 plug on a computer puts out, but others such as most samsung chargers are capable of 2000mah outputs. If you battery cant handle the much or the wire/connections with you device it can fry your stuff in short order. The cable is just the "messenger" carrying the current from the source. If it says to charge via usb port on a PC then you want a 500mah 3.7v output.

Hope this help clear it up some.

USB cables are supposed to be standard, but I've had experiences that suggests otherwise. My Asus t100 and Sony Xperia z1 won't charge properly unless I use the cables that came with them, even though I'm using the wall adapters that came with the devices. Then again, both of those require fairly high charge currents whereas the eroll probably doesn't.

The cable merely connects the devices...and yes they are standard although some have those bumps on them (noise reduction chokes) and of course some may be of inferior quality.

It's the charger that is the key...just make sure it's rated the same and you should be fine.

Yeah, when it come to batteries don't screw around. Make sure that you are charging them with a device that is made to charge them.

Some devices that require high charger outputs need an USB cable that has an extra wire to allow "fast charging". Those cables will work with normal lower output charging devices but not vice versa.

Yes, and then we have the OTG cables required for data transfer on smartphones. E-cigarettes don't take a high current though so I'm thinking any usb cable should work.

out put specs for usb ports is 5 volts at 500 ma.
its the charger itself that counts.
all usb port enabled chargers are 5 volts at the input.
the most important aspect is the out put voltage.
a 3.2 volt charger wont hurt a battery that requires 4.2 volts fully charged.
it just wont charge the battery to its full potential if at all.
a 4.2 volt charger will over charge a 3.2 volt battery possibly causing damage.
this is also how quick charging is accomplished.apply more voltage than
the battery is rated for a set x amount of time.
some chargers and batteries enable the data line to communicate with each other
to select the correct charging profile.
the trouble is no one knows unless specifically informed the internal working of the charger
or battery.
rule of thumb is match the voltage output of the charger to the battery.
current is regulated by the load.max output current by the charger.
this means even if the battery can handle a higher current when charging
the charger limits the current to its maximum out put rating resulting in
a longer charge cycle.

Exactly the kind of well-informed response I was looking for, thanks!
