Advantages and disadvantages of wireless chargers

For some time, it is more and more common to see devices with wireless charging: both mobile phones, smartwatches or others. At the same time, this has caused wireless chargers to begin to proliferate.

This type of systems may seem very attractive at first, since it eliminates most of the cables that we usually need. In addition, it is really comfortable to reach a room and be able to place the mobile without having to connect anything: simply, place it on the surface of the wireless charger.

But is it really useful? The reality is that it is a system where the advantages are few but functional, while the disadvantages are several and, although they are not obvious at first, it is necessary to take them into account. Especially before buying one of these devices.

Pros and cons of wireless charging

First of all, the biggest disadvantage is that it is a system that spend much more than the traditional. The Wireless Charging Consortium (Wireless Power Consortium) has been noting that they are very inefficient chargers -between 39.6% and 59.4% -. At the same time, this causes more energy to be used when charging a device wirelessly than using a cable.

Second, wireless charging, and surely the one that affects us the most, is that it can shorten the useful life of our mobile battery. This method causes the battery to heat up more than usual during charging, which causes it to degrade faster than if we used a charger with cable.

So do you have any advantages? The reality is that yes, although we will be the ones who have to assess them and decide if they are worth it.

The first is that, being slower load, the process itself affects the battery less – especially if we take into account the fast charging of 18, 20 or 25W, which greatly accelerates the degradation of the batteries. In other words, the heat can shorten its life, but it is somewhat offset by the benefits of slow charging.

The second is that wireless charging is a much more comfortable system. It is ideal for those terminals where the loading port has been broken or has problems. Another is that it is a “universal” system, that is, if the mobile is compatible with this system, then the brand of the charger does not matter.

Some recommendations

If you are one of those users who find more advantages than disadvantages. And you would like to have a wireless charging port for specific moments -for example, it can be very comfortable for the office-, then we recommend these three models:

Charger 10W Nanami

For 22.99 euros, the Nanami charger is a good option for those who are looking for a wireless charger to leave on the table from which we telework or at strategic points in the home. It is a port compatible with fast charging of 10W and 7.5W and LED indicators that show the status of the charge.

Anker PowerWave Pad Charger

One of the big brands when it comes to chargers and portable batteries is Anker and, how could it be otherwise, the PowerWave Pad can be a great alternative for those looking for the best quality / price: for € 17.99.

Regarding the technical section, it is similar to the previous one: 10W or 7.5W and 5W load for some models.

For 18.99 euros, we are faced with another wireless charger that complies with all of the above: 10W, 7.5W and 5W for a few models. Also in line with the rest of the options, it is compatible with any mobile with wireless charging.
