When choosing the best USB wall charger, it is important to find one with the correct type of USB plug, or one that allows you to use your own cable. Choosing the best USB wall charger for your needs may also depend on the types of devices you have and if you will need to charge more than one at a time. Many modern electronic devices and other gadgets use a standardized type of power port known as universal serial bus (USB). Cellphones and various other devices commonly use micro or mini USB plugs in particular.
Due to the way they operate, one USB wall charger is typically interchangeable with another. There may be exceptions, so it is a good idea to verify the power needs of your device before purchasing a USB wall charger. In most cases, choosing the best USB wall charger will come down to factors like design, convenience, and portability. Some chargers are portable, while others support multiple devices or have other useful features. In addition to wall chargers, certain travel USB chargers may also allow you to plug into a 12 volt power source.
If you will be traveling with your charger, it may be best to find a flat, compact unit with a collapsible plug. Features like these can allow the unit to be stowed away for easier transport. Some USB wall chargers are so compact that they consist only of the wall unit, allowing you to plug a separate USB cable in that matches your particular device. Since this cable can also be repurposed to connect your cellphone or other gadget to a computer, you can further reduce the amount of clutter you will need to pack.
Other USB wall chargers allow you to plug in multiple devices at once. These charging stations may also allow USB cables to be plugged in, depending on the design. If you have a number of different devices that you would like to charge at once, a universal USB charging station might be the best choice.
Wireless charging is a method of powering cellphones and other devices that may offer USB options. While some products come equipped with the ability to accept a charge from wireless stations right out of the box, USB adapters are often available for existing devices. This type of wireless USB wall charger may also be useful if you have a number of items to charge at once. If a large tangle of wires is something you want to avoid, then this type of charger may be the best choice.
