School Check-List: Laptop, Tablet, Smartphone, Dual USB Wall Charger

By Johny Jacson


Education has gone digital, and students these days demand more and more devices to cope with their learning needs and preferences. Gone are the days of regular books, notebooks, and pens, and here come the tablets, phones, and laptops among others.

Staying in dorm rooms is convenient for them to be near their schools, but these rooms only have a few outlets which are often reserved for appliances like refrigerators and air conditioners.

People barely put down their gadgets for their remarkable ability to keep them occupied. With people always carrying their devices, charging must be smart and finished in no time.

Before the dual USB wall charger that made living trouble-free for people who are always on the go, there was only the simple battery charger. It works by providing a pulsed DC power source to the battery management system (BMS) of the device. The flow of current is continuous and non-adjustable according to the time of charge. It's so simple, that along with its inexpensive price, it takes a long time to charge a battery to avoid overcharging by any means.

The different currents characteristic should be highlighted because this allows the two devices to be charged at the same time at full speed without sharing power. Within a few hours, multiple devices can be fully charged, two at a time. Therefore, even power hungry devices can be charged quickly.

The next step for improvement was developed by Apple, which featured a universal USB port for all types of Apple products, until other brands developed on producing smaller chargers with USB ports as well. Now, charging is improved more than ever thanks to the universal dual USB wall charger developed by Vority.

This charger is universal, which particularly means that it is compatible with any device that can be charged using a PC or a Mac USB 2.0/3.0 port. Although the ports are labeled with "tablet" and "phone," other devices, such as iPads, Music players, cameras, and Bluetooth devices can be charged using either port. There's no more discrimination between Apple and non-Apple products, or between big and small items. When not in use, the charger's prongs are foldable, making it compact and easy to store.

A very useful advantage of the dual USB wall charger is that it's able to automatically stop charging when the battery of the device it's charging is full. In addition, the current capacity, the device itself, and the USB cable contribute to limiting the charging current that enters the gadget.

The dual USB wall charger is light and small, suitable for roaming users who are always outdoors. People won't have to look for the device's assigned charger among the sea of chargers and wires. All they have to bring along is one universal dual USB wall charger and USB cables.

Using a dual USB wall charger that is designed for fast-paced lives, people will never have to wait that long for their gadgets to recharge one at a time.
