There are lots of times you go into stores looking for car chargers and grab the first thing in front of you. When your phone is about to die and you plug-in the car charger hope to bring it back to life, only to realize after the 20 minute drive that you have an extra 10% which will probably give you another 30 mins to an hour of use.Chargers range from 0.750A to 1.750A, and most of them are on the lower range, be sure to check the car charger output so you know the power you will charge with. Simply put the higher the better.
The TYLT car charger is one of the best I have one as how fast it can charge, at 2.1Amps it really charges your phone quickly. I have found that they are consistent with the power output and this applies to both MicroUSB and Apple products. There products are cleanly made and in it almost chargers a percent a minute, so in a 25 minute ride you would charge up to 20% which is amazing. There are other products who advertise the high Amp output, but only TYLT and Griffin seem to be legitimate, and in this case I highly recommend TYLT chargers, all their chargers are dual chargers, the long flexible one and the v-split charger. I first found them in Virgin in Dubai Mall, but you can also find them on Amazon.
