Since that device charges via a provided USB micro cable, the current capacity of the adapter should make no difference. The "charger" itself is internal.
hmm, depends. on many of the cheaper clone copy, forgeries, the circuitry isn't designed to handle a higher amp input, sometimes, and sometimes this can cause some devices to like, behave erratically. any where from ego's launching and sticking animate and inanimate objects, to lippo box mods billowing black smoke, like phelps just got a message and dive is self-destruct or something like that.
With any device with designed circuitry, tis best not go outside their programed parameters. To me it's a warning Will Robinson, asteroids.

People confuse with "USB Power Sources" with "chargers" A USB power source puts out 5V. It needs to have a current rating high enough to accommodate the current your charger will pull from it. Using a USB power source that's capable of producing more current than that is not a problem.
the amount of current drawn depends on the load.
the load will only draw as much current as it was designed too.
the load doesn't know or care that the source has more power available.

bad circuit design.
worst case scenario,the circuits lose efficiency and shut down.
this tape has been out for a while with no real proof that an e-cig
was even involved.

If you're especially concerned, get a USB current meter (I've seen them for under $10) and make sure the device is drawing a reasonable current to charge the kind of battery it has. Under 500mA should be safe for any of those devices. I'd think they all should be under 1C (i.e., max mA drawn during charge < battery capacity in mAh)

to make sure we are talking apples.
any device with a female usb port is not a charger.
whether its on a computer or wall mounted device.
this is considered a power supply.
minimum requirements are 5 volt output at 500 ma per usb port.
devices that have the male usb port for direct power or charging
are generally rated at 5 volts input and (480 ma or less to operate).
these include chargers,mini nerf missile launchers,fans and
and passthru cables.
i have seen usb power supplies rates at 2.3 amps output.
these can emulate 4 usb ports with power to spare.
these are also necessary for so called quick charge devices.
chargers or charging circuits used in these devices deliver
more than the 420 ma that a standard ego style charger
and charge the battery quicker. ego type batteries are
designed to handle a charge current greater than 420 ma.
the reason most chargers are rated 5 volt 480 ma was
to meet the usb standard and not overload your computers
power supply. now plug in power supplies are becoming
popular.
can you use a quick charger on your computer port?
it depends. count the number of ports on your computer
and multiply the amount of ports by 480 ma.
with 4 ports there should be 1.92 amps available for use
as all the ports use the same power supply.
if ports are already being used subtract 480 ma for each
port in use to find how much power is left for use.

I wouldn't count on that. Computer ports generally shouldn't have loads that draw more than 500 mA plugged into them. In principle,. no load should ever draw more than 500 mA from a USB power source without ascertaining that the power supply is capable of providing more. There are a couple of different "Standards" for how that's done, and at least one of them is pretty much precludes transmitting data from the same port.
That is the correct way - no more than I think 100mA without negotiating 500mA under USB2.0. Apple and maybe others allow computer ports to negotiate via a non standard protocol higher currents. Macs go to 1100mA. USB 3.0 has a different set of current levels. It may also be more officially forgiving of the large number of USB "devices" that don't even connect to or use the data lines at all.
It should make no difference to a device if a USB port is capable of 500mA or 3000mA. Concevably a very poorly designed device could rely on voltage sag from an overloaded 500mA port. Who knows. Probably not worth worrying about. Just, it used to be a pain to measure port current. Now it's an easy $5-10 monitor.

480mA or 480mAh? The smallest ecom-c I see is 650mAh. USB supplies are usually rated 500 or more mA. 480 would be odd, but possible (and of no consequence vs 500).
The ecom-c (twist) definitely has the charge controller in the body.
Their description says connect to computer or "a wall adapter". Not even "only our wall adapter". The ecom-c also clearly has microprocessor circuitry in it for power regulation and battery status, so it's not like it's just a battery in a shell with a USB socket being misused as a charger connection. Doubt something like that was ever made, but who knows.
