Want this question answered?
2 ports USB charger (1A). I was surprised at how much faster it recharged my phone than using my laptop port.
two times faster
Because, my dear Watson, the car moves faster, so obviously the charger does, too. Elementary, my good friend.
parallel port if you want to know why go to it140 if you know what that is.
Blue port. If you have the rear air then the charge will be greater than front air only.
USB is faster than a parallel port because it is based on a much faster technology. The bus speed is considerably faster and uses a more user friendly interface.
Phone will charge faster with a larger charging current. Charging current depends on voltage, so your home charger likely has a higher voltage and therefore a higher charging current.
no it cannot charge a computer. a phone battery does not have enough power to charge a computer. maybe it can it the phone battery has a bigger capacity than the computer (which is imposibble)
Twice as fast.
Twice as fast.
The charger with the 900ma output will charge the battery faster than the charger with a 500ma output. The phone with the 900mah battery will last longer between charges than that of the 500mah battery.
I wouldn't imagine it would. If it's a decent charger it should regulate the current, regardless of input voltage. But if it's cheapo, then it's likely it will charge faster with the car running, rather than being off.
