Choose the Right USB Cable for Your Apple iPhone 4

One of the most crucial pieces of equipment for any Apple iPhone owner is the charging cable. From charging your battery to connecting to other devices like your computer, iPad, or iPod, the right cable can help you get the most out of your phone.

What is a USB cable?

Universal serial bus cables are used to connect your Apple iPhone, iPad, or iPod to your computer or to your other devices. They have become the technology industry standard for battery charging and data sync activities because they offer many advantages, such as:

  • Convenience: USBs can be used to carry both power and data, so you dont have to switch cables when you need to switch tasks. USBs can also be disconnected from a device while it is still running without causing the device to freeze up.
  • Speed: USBs can transfer data or electricity at speeds of up to 480Mbps compared to only 20Kbps for earlier versions.
  • Universal standards: Manufacturers use a set of universal standards, allowing a single cable to be used on multiple devices. Apple uses the same connector type across all devices, meaning users dont need to have separate chargers for their iPhones, iPads, iPods, or Macbooks.
What charger do you need for the iPhone 4?

The iPhone 4 requires the Apple 30-pin USB connector for its charger. This is a flat, wide connector that was used in most Apple mobile devices between 2003 and 2012, including the iPhone 3 and iPhone 4 models and iPad, iPad 2, and iPad 3. While you can use Apple 30-pin chargers interchangeably among these devices, you should use only the device-specific charger that will provide the appropriate wattage. In September 2012, Apple began using its proprietary lightning USB connector on chargers for all of its devices.

How do you pick a cable for your iPhone?

There are many different USB cables for iPhone 4 phones. Consider the following features when making your selection:

  • Length: You can find options ranging in length from a few inches to several feet. The USB specifications limit cable length to five meters, which is approximately 16 feet, 5 inches for full-speed devices, and three meters, which is approximately 9 feet, 10 inches for low-speed devices. Apple products are all categorized as high-speed devices.
  • Connector type: There are several different types of USB connectors. The iPhone 4 requires Apple's proprietary 30-pin connector. Apple uses the lightning connector across all of its newer devices starting with the iPhone 5. The lightning connector cannot be used with earlier versions of the iPhone.
  • Style: While these cables originally only came in black or white, you can now find cables in a wide variety of colors. You can also find a style that matches your personal tastes, including flat, round, braided, or even light-up LED cords.
