Most mobile phone car kits will include several key components which are fundamental to any driver. These are a headset, Bluetooth adapter, in car charger and signal booster.
Why in car chargers are essential
If you are going on a road trip which might take several days then having a working cell phone is going to be very important because of emergencies. Now because of the latest technological improvements model phones can do a lot more such as browse the Internet can record videos. However these tasks greatly reduce the battery life of the device. Without an in car charger your battery will die in about 5 hours time.
Mobile phone car kits price range
Ideally you do not want to be spending more than $30 for such a kit. They do provide great value but at the same time you have to get a good sale or cheap discount. Amazon and eBay are the best places for this online. Otherwise you can go to your local market and try to negotiate a better price. Print off an online offer if you think this might help you with the negotiations. In my experience this can always reduce the price of the online price is competitive.
The top end of the range will be around $70 but here all the components will have higher levels of quality which in my opinion is not really worth paying the extra money for as the cheapest mobile phone car kits can do all the same things just as good. iPhones are a great example of why you need these kits so make sure if you buy one then you also buy the other.
