Features To Look For In Buying A Dual USB Wall Charger

By Johny Jacson


A good thing about our gadgets today is the availability of various of available accessories. Phones and tablets with music players now have a wide array earphones to choose from. There's a lot of choices ranging from simple black colored ones all the way to big bass headphones.

This is also true for the chargers. Currently, there are a lot of chargers available in the market. And sometimes it's a disadvantage as well. It's just so hard to choose which charger to buy.

This way, bringing chargers along on trips becomes a hassle. Some are heavy and even bulky. Charging one phone would require its corresponding portable charger, and charging one tablet would require another.

Dual USB wall chargers have different features and styles. They come in different colors and sizes that it gets confusing choosing a charger for yourself. Well, don't worry. Here are some few features to look out for in choosing your own dual USB wall charger:

The Universal Serial Bus (USB) was developed in the mid-1990s that is a technical standard characterized by a unique engineering process and design. It is identified with connectors, cables, and communication procedures used for connecting devices as means of file and media transfer, mass storage, or simply power supply. It was specially designed to standardize connections that started with computer parts like keyboards, pointing devices, audio speakers, microphones, printers, disk drives, and other input and output computer devices.

The 2.4A port can also charge cell phones, iPads and other compatible devices, while the 1.0A port can also charge MP3 players and GPS devices. Cameras, Bluetooth headsets, and power banks can also be charged with the dual USB wall charger.

You see, not all chargers have this. Some are very specific in the wattage that they can carry while some are more flexible. Of course, choosing the right wattage for your gadget is also essential.

Second, choose a dual USB wall charger that is lightweight. Being a dual USB wall charger, it must first and foremost be very lightweight in order for anybody to carry them around. There are ones that are quite heavy. Therefore it is important to choose one that is lightweight and very portable so that you can carry it anywhere.

This may be caused by accidentally connecting two USB power supplies to each other, so the USB design was made to be distinct. That is why USB connectors are either type A or type B, depending on host devices that supply power and target devices that absorb power. Later on however, with the development of USB interfaces, multi-purpose connections have made it possible to for similar types to attach, which are used in smart phones and USB-powered Wi-Fi routers.

The next time you are scouting the internet and trying to look for a charger for your phone, keep in mind the different features that you have to look for in buying a charger.

The dual USB wall charger has efficiently replaced previous interfaces because of the USB feature, becoming more functional than serial and parallel ports and power chargers for mobile phones, tablets, media players, and the like.
