I don't know how many times a day I look down at the battery on one of my devices and think wow I thought I just charged this thing! Having a charger in my car is essential for me right now because I have two jobs and the amount of time I spend in my car is staggering. I'm on call literally 7 days a week and sometimes I forget to charge one of my multiple iPhones or iPads. What I like about this Power Gen 2.4 Amp charger is that it gives me two USB ports of variable power. The 2 Amp port takes care of the high draw devices like my iPads and the 1 Amp port handles the lower draw devices like my GoPro Hero+LCD or my iPhones.
In my opinion having the 2Amp port is essential because it will charge my iPhone twice as fast as the common 1Amp USB chargers. This may effect the battery performance towards the end of the battery life of my iPhone, but I will be ready to upgrade by then and the trade off is worth it.
Power Gen also sells a wall charger and car charger combo for $12.99 as opposed to $8.99 for just the car charger, but either way the cost is nothing compared to how often you will use this little powerhouse. I actually have 3 different chargers from Power Gen that I use on a daily basis and I love the availability of an extra port and the speed of charge.
If you are thinking about getting a car charger forget about the dedicated 1Amp charger and take a look at this little guy.
What about you? Do you have something that you use everyday to make life a little easier?
