Best wireless chargers buying guide
Wireless chargers are becoming increasingly popular thanks to their convenience and practicality. With a wireless charger, there's no need to connect your device to a cable to charge it. Instead, you simply place the device on the charging pad and you're good to go.
But how do wireless chargers work? Firstly, it's important to know that these devices use inductive charging technology. This means that the charging pad contains a coil that generates a magnetic field when powered by a source of energy. When you place a compatible device for wireless charging on the pad, the device's coil detects the magnetic field and converts it into electrical energy to recharge the battery.
It's important to note that not all devices are compatible with wireless charging. To be able to charge wirelessly, devices must have an integrated receiving coil. This feature is common in newer mobile phones but may not be present in other types of devices such as tablets or laptops.
In addition, there are different wireless charging standards such as Qi, PMA and A4WP. The most widely used is undoubtedly the Qi standard, developed by the Wireless Power Consortium (WPC). Most of the wireless chargers available on the market use this standard.
In our guide to the best wireless chargers, we'll explore the different options available and help you choose the best wireless charger for your needs.
How Wireless Chargers Work
Wireless chargers are devices that allow you to charge your electronic devices without using cables. Instead of connecting your device to a power outlet or computer, you can simply place it on a charging pad and the charging process starts automatically.
But how exactly do these chargers work? Wireless chargers use inductive charging technology. This technology uses the principle of electromagnetic induction to transfer energy from the charging base to the device that needs to be charged.
The charging base contains a coil that creates an alternating magnetic field. When you place your device on the charging pad, the coil inside the device receives this magnetic field and converts it into electrical energy.
This energy is then used to recharge the battery of your device. The charging speed depends on the power of the wireless charger and the type of device you're trying to charge.
It's important to note that not all devices are compatible with inductive charging technology. To use a wireless charger, your device must have integrated Qi (pronounced "chee") technology. Qi is a universal standard for wireless charging developed by the Wireless Power Consortium.
- Example: If you own a smartphone compatible with Qi technology, you can simply place it on a charging pad to begin the charging process. However, if your device is not compatible with Qi technology, you will need to use an adapter or a special case in order to use a wireless charger.
Advantages and disadvantages of using a wireless charger
Using a wireless charger has several advantages, but also some disadvantages to consider. Here's an overview of the main ones:
Advantages
- Convenience: With a wireless charger, there's no need to connect the device to the power cable every time you want to recharge the battery. Just place it on the charging pad and you're done.
- Simplicity: Using a wireless charger is very simple and intuitive, especially for those who are already familiar with Bluetooth or NFC technology.
- Space saving: Without power cables, your desk or bedside table space will be more tidy and clean.
- Compatibility: Wireless chargers are compatible with many devices, including smartphones, tablets, smartwatches, and other products equipped with Qi technology.
Disadvantages
- Slower charging speed: Wireless charging can be slower than traditional charging via cable.
- Heating: During charging, some devices may overheat due to the energy transmitted by the charging pad.
- Distance: Devices must be placed close enough to the charging pad to function properly, which can limit freedom of movement.
- Cost: Wireless chargers can be more expensive than traditional power cables.
In conclusion, using a wireless charger can be very convenient and practical, but it's important to carefully consider the advantages and disadvantages before deciding whether to purchase it or not. If you're always on the go, for example, you may prefer a traditional charger for its speed and portability.
What to consider before buying a wireless charger
Before purchasing a wireless charger, there are some things to consider to ensure that you're making the right purchase. Here are some important factors to keep in mind:
Type of device
The first factor to consider is the type of device you want to wirelessly charge. Not all devices support wireless charging, so it's important to check if your smartphone or tablet has this feature.
Charger power
The power of the wireless charger is another important factor to consider. Wireless chargers have variable power, expressed in watts (W). The higher the power, the faster the charging will be. However, not all devices support higher powers, so it's important to check what is the maximum power supported by your device.
Design and Size
Wireless chargers come in different shapes and sizes. Some are designed to be used only at home or in the office, while others are portable and can be used anywhere. It is important to choose a design that meets your needs.
Price
The prices of wireless chargers vary greatly depending on the brand, features, and quality of the product. Before making a purchase, make sure to compare different products available on the market and choose the one that offers the best value for money for your needs.
Compatibility with Device Case
If you use a protective case for your device, it is important to check if the wireless charger is compatible with it. Some chargers may not work properly with certain cases or may require the use of special adapters.
- In summary, before purchasing a wireless charger, consider:
- The type of device you want to wirelessly charge
- The power of the charger
- The design and size of the charger
- The price
- The compatibility with device case
