Have you heard about induction chargers or wireless chargers? They have been drawing the attention of users of electronic devices, especially smartphones, in recent years, shortly after Apple announced the iPhone 8, which was the first in the line to adopt wireless charging technology.

But it is important to bring a curious fact. Apple wasn’t the first to integrate wireless charging into its phones. The Nokia and Samsung brands had already taken the first step. The iPhone maker just gained more visibility in the sport for being the most popular smartphone company in the world.

Talking about the induction charger, it allows devices to be recharged without the need for connectors or cables, using the principle of magnetic induction to transmit electrical energy from the charger to the device. To charge, simply place the device close to or positioned on the induction charger.

The most popular wireless chargers in 2023 are:

  • Yootech F500
  • Xiaomi Qi Fast Charge
  • Mophie Wireless Charging
  • Samsung Duplo Pad
  • Anker PowerWave A2524
  • Samsung Slim

Despite the growing popularity of the induction charger and its practicality, it is important to consider some aspects before purchasing it. To help you make that decision, we present below the advantages and disadvantages of this type of charger.

Induction Chargers: Pros

Induction Charger Pros












There are many advantages to purchasing induction chargers. One of the main ones is the convenience and convenience that this type of charger offers.

In addition, induction chargers are more resistant and durable, which can result in an extra advantage for the user, as it is a long-term investment.

Discover now the main advantages of induction chargers.


The fact that these chargers are wire-free means you don’t have to worry about cables or connectors. If you hate a messy environment, with wires everywhere, this charger may be ideal for keeping your work or leisure space organized.

Improves the lifespan of your device

That’s right. Using physical connectors can wear out your device over time. On the other hand, induction chargers do not affect the input of your devices and even cause less heat to the device, offering less wear in general and reducing the loss of your device’s data interface. Therefore, even though these chargers are more expensive than conventional ones, they can help you spend less on maintenance or even on purchasing a new smartphone.


The fact of not having wires makes these chargers safer. Thanks to the use of magnetic fields that are generated by the charger and received by the device, the risk of electric shocks or short circuits is minimized. It is important that the products are original and purchased from trusted stores so that security is maintained and you have access to this additional benefit.

Accessible for all induction appliances

Devices that charge by induction are compatible with all chargers available on the market, unlike devices that are charged through wires, which need to have the same input format as your charger.

Nice presentation

If you care about the beauty of the environment, the induction charger is an excellent choice, as it makes any place more beautiful, attracting the attention of visitors who are more aware of technology. The wireless charger can be used on tables, bookshelves and shelves without detracting from the elegance of these furniture.

Energy saving

Induction chargers can help you save energy because some models have lights that change color according to the percentage of charge. In this way, the user can clearly and visually know if their smartphone is already fully charged or if it still needs more time in the base.

Induction Chargers: Cons

While there are many advantages to purchasing induction chargers, there are a few reasons why people might choose not to purchase induction chargers. One is that these chargers can be more expensive than traditional wired chargers.

Another reason is that cheaper or older induction chargers may experience connection issues between the device and the charger, resulting in slower or intermittent charging.

Learn about other common disadvantages of this type of device.

High Cost

These chargers are currently more expensive than traditional ones. Thus, they end up not being as effective in attracting more people to use them, as low-income mobile device users end up opting for conventional chargers. If you want to use a wireless charger, you’ll have to do your research to find a good value for money.

Limited Compatibility

Another factor that causes the induction charger to be overlooked by many is that it has limited compatibility with devices. As not all devices accept this type of charging, it ends up being associated with more expensive products. In addition, some models of cases may interfere with the operation.

Slow Charging

Although induction chargers have evolved in recent years, they still charge slower than conventional chargers. For example, on the iPhone 13 Pro, wireless charging reaches a maximum of 15 W and wired at 20 W. With 15 W, the battery of the cell phone manufactured by Apple goes from 0% to 100% in about two and a half hours. Currently, a small number of manufacturers have higher fast charging wireless chargers. Therefore, always check the battery capacity of your device and the power of the charger.

It’s not completely wireless

Many people looking to purchase an induction charger have the mistaken expectation that wireless charging means being able to move around freely while their devices are charging, as with a mobile network connection or WiFi. But that’s not the reality. With induction charging, you need your device to be positioned on the charging pad for the entire time you want it to charge. Thus, wireless charging is not exactly “wireless”, but it does offer the convenience of not needing cables to connect the device to the power source.

Is it worth buying induction chargers for your cell phone?

Although induction chargers offer numerous advantages, they are still not a perfect alternative to conventional chargers due to limitations that still need to be overcome.

However, it is important to highlight that they have unique characteristics that make them an attractive choice in situations that require sophistication and convenience.

Therefore, the selection of a charger must be careful, considering that it is a fundamental investment for the preservation of your devices and that this is still a technology in transition.

Common questions

Can a wireless charger ruin your cell phone battery?

In general, the answer is no. If the charger is of good quality and original, there will be no risk to your smartphone’s battery.

Is it normal for the cell phone to heat up when it is charging by induction?

Yes, it’s normal. The induction charging system generates mild heating that varies from device to device, but does not harm your cell phone.

How do I know if my cell phone charges by induction?

This information is usually on your device’s box, but virtually all newer high-end cell phones use this standard. This is the case for iPhones from 8 and up, and Galaxy models from S9 upwards.
