If you are looking for a quality Apple iPhone car charger you will find many choices. You will find that while you can get a car charger for a low price, they often fail after a few months and in some cases even sooner! It's worth it to spend the money up front to get a quality product that will last as long as your phone does.
You can run into many issues when purchasing a lower quality charger, including an incompatibility with how much power is needed. The different models of the iPhone don't always require the same charger. The new models need a higher amp charger to make sure they get the power they need for a full charge. You also want to make sure you don't damage your phone by using a lower amperage charger. Make sure the charger you purchase matches up to what your phone requires!
Another problem you can run into with lower quality iPhone car chargers is cheap quality. Not only can the cord be cheap and break easily, but the connector can break, but also damage your iPhone. It's not worth saving a few bucks if you end up having to pay for an expensive repair for your phone. Spend the money up front on your charger and you won't run into this problem.
There are a few different types of chargers you can purchase for your Apple iPhone. One will have the cord attached, which is nice but can be a mess when you aren't using it. Either you leave it hanging from the power outlet, or it gets tangled up in your glove box. Another style has a USB port built into the charger, and you can plug and unplug the cable from the base. This way you can leave the charger in at all times, and simply stow the cable when it's not in use. Most of your higher quality chargers will be of the two piece type, although this isn't always the case. You will also see a difference in the size of the base as you move through the price ranges. When you choose a higher quality charger, you are likely to find that by using higher quality parts they can put them into a more compact and less unsightly package. A few are even flush mount, so that hardly anything comes out above the edge of the power outlet.
Take all of this into consideration when you are shopping for your Apple iPhone car charger and the purchase you make will be with you for years to come. You want to consider the quality of the build and the components, as well as compatibility with your phone. You want to make sure it will not only perform well, but protect your investment as well. Having to buy a new charger, or even a new phone, every few months will quickly make you wish you had spent the extra money in the first place for a quality charger.
