Car USB Charger Buying Tips

Updated on September 28, 2011

Charge Your Gadgets on the Go with a Car USB Charger

If you have portable electronic devices that charge using a standard USB connection, a car USB charger can be a very convenient item to have. In most instances they can charge MP3 players, cell phones, digital cameras, GPS devices and other items while you're driving using your car's cigarette lighter.

Learn a bit more about these affordable chargers and find some for sale on this page.

Tips for Choosing the Right Device

The average car USB charger is very affordable and will take up little space. They should charge most portable devices that use a standard USB connection. When you purchase one of these devices you might want to consider just a few things.

  • Number of devices
    Some of these chargers are capable of charging only one device at a time, others can accommodate two at a time.

  • Status
    It can be useful to know when the device is charging and when it's done with the task, therefore an LED indicator light is very handy.

  • Protection
    The best car USB charger should offer circuit breaker protection and ideally, surge protection as well.

  • Flexibility
    If you want the charger to work in a 12v socket and standard AC outlet as well, look for this feature.

  • Compatibility
    Obviously, you'll want the charger to be compatible with the devices you want to charge. Some models are designed specifically for a given device (for instance, an iPhone) but others are more universal. If the device you wish to charge uses a standard USB connection and requires no special software or adapter, many of these chargers will work. You might also want to check the power requirements, specifically how many milliamps are needed and match that up to what the charger can handle. (i.e.: 700 mAh or 800, etc.)

  • Connection
    Most of these USB car chargers merely accept the USB charging cable that comes with your device. Without this cable, you may need to purchase the cable separately.

      it is told, that some divices have a kind of blocking system to prevent usage of universal chargers, so you have to use only the charger which is purchased with the device.

      is it true ?

      Great tips. Since many devices charge via USB these days, it's great to be able to have a universal charger in the car.
