Comparing USB Charger And A Wireless Charger

By Johny Jacson


The wireless USB charger is one of the newest innovations in the mobile device industry. More and more users are turning to wireless chargers simply because these are extremely convenient to use, even when traveling.

It is a combined USB wireless charger. What is that, then? More like a universal charger that features USB ports for those devices that have USB adapters for their chargers and those devices that are Qi tech inductive power standard enabled.

QI technology is a new interface standard developed to transfer electrical power through induction up to a maximum of 4 centimeters. The Qi inductive power transfer system consists of a compatible receiver to be paired with a power transmission pad.

When the Qi-enabled device is placed on the transmission pad, the battery is charged through resonant inductive coupling.

Now, you find in the market this new charger type that combines the two kinds of charging device into a USB wireless charger type.

The next thing to consider is the specifications. Average power output is rather low at 5 volts, but this is understandable given the other features of the wireless charger. Chargers with higher power output can fill up your devices much faster.

First, you will plug this wall adapter to your power outlet. As the device has combined the wall adapter with the actual charger, there will only be the plug wire and the actual charger. A red light will indicate that the charger is working properly. Incidentally, this light is not the kind that obnoxiously disrupts your vision at night, as it is visible, but not too bright.

Check feedback indicators like lights and sounds as well, because these will let you know if the charger is functioning properly.

Devices usually have a USB port dedicated to docking the USB charger's wires. These ports can get damaged through use and would require replacement. With the new Qi technology, the only time you're going to need to dock that connector wire is when you're transferring files to a non-Bluetooth enabled device.

The device should either be manufactured with a Qi technology receiver or is equipped with one that can be purchased for certain types and models of devices.

There are new charging devices released in the market that feature both the USB type and the Qi-tech wireless type in one package, like the Vority combined Qi-standard and USB charger.

These are just several of the factors you have to look into when buying a wireless USB charger, but these should help you start picking your own wireless charger already. For starters, you can try Vority Ki+4, the first combined 4-usb-port and wireless charger, as it performs well on these criteria.
