Are you bored of constantly losing your charging cables? Perhaps the clutter on top of your table is annoying you? If that is the case, then it is time to buy a wireless charging pad.

Wireless chargers not only help you cut the cable clutter but also they are harder and don’t break as easily as the simple charging cables. Of course, there are special magnetic charging cables that can help in some cases but they are not the same as having a wireless charging pad.

The idea is simple. You sit in front of your desk, you drop your phone on top of a charging pad and the juice starts flowing to your phone. There is no need to connect cables and such. Their cost is not prohibitive and as such you should consider buying one if your Android phone or iPhone device supports it.

How wireless chargers work

In Wireless charging systems there are two coils that generate a magnetic field. One of the coils is located inside the charging pad and the other inside the mobile device. Using these two coils, a transfer of power is occurring from one device to another via air due to the magnetic field.

The coil inside the charging pad is the transmitter. The second coil inside the phone is the receiver. If the mobile phone does not have any such coil, then the phone does not support wireless charging. There are two types of wireless charging. The first one is the inductive charging and the second one the resonant charging.

Inductive charging

In inductive charging, the transmitter transmits electricity through the air by using a magnetic field. In other words, the transmitter converts the electricity to a magnetic field. The receiver on the other side, receives that magnetic field and using the coil converts it into electricity.

This kind of charging has the drawback that both the transmitter and the receiver must be in a close distance. The more far away they are, the less capable the system is, meaning that there is much less transfer of electricity from the transmitter to the receiver. The best would be that the distance should be less than 5 to 6 mm in order to transfer electricity efficiently.

Resonant charging

This type of wireless charging is a bit more complicated than inductive charging. It has the ability to transfer electricity between coils that are further away. As such, they don’t need to be close to each. Both coils, the transmitter & the receiver should have the same resonant frequency. One of the drawbacks is that the transfer of electricity between the source and the target is much less efficient.

It is universally compatible with all Qi-enabled smartphones. It can wirelessly charge iPhones at 7.5 W, Samsung Galaxy phones at 9W and the rest phones with wireless charging capabilities at 10W.

It has an LED light in front that indicates that your phone is correctly aligned on the pad and is charging. And not only that, it also has foreign object detection. The LED lights that it has can alert you of foreign objects such as keys and coins that could affect the wireless charging of your device. The foreign object detection mechanism helps to prevent the charger emitting unnecessary power and heat that could damage your smartphone.

The device is coming in four different color finishes. You can find it at $48.99.

Very cheap

Can’t work on your phone while charging
Doesn’t include a power brick

For us, the TOZO W1 is one of the most stylish wireless chargers on the market. It is made from CNC (Computer Numerical Control) processed aluminum which is of aviation grade. Due to its aluminum construction, it is significantly tougher and more durable than any other plastic charger in the market. It is so thin that it barely is 0.2 inches (5mm) thick. It has a diameter of 3.94 inches (10cm) and comes in a plethora of color options.

The TOZO W1 is coming with three charging modes. A standard charge mode of 5W, a fast charge mode of 7.5W and a 10W fast charge mode. Both fast-charge modes require a QC (Quick-Charge) 2.0 or 3.0 adapter in order to operate.

Like a lot of other chargers in the market it is equipped with intelligent foreign object detection mechanism that will stop it charging if other metallic objects are placed inside its wireless charging zone. Its over-heating, over-charging and short-circuit protection provides a safe environment for your phones while charging.

Unfortunately, that device has also two small drawbacks. The first is that although it includes a USB Type-C charging cord, it doesn’t come with a power adapter and as such you will have to provide one of your own. The second one is that because the phone is laying flat on the pad it is difficult to work with it compared with the charging stands.

You can find TOZO W1 charging pad at $11.99.
