The durability of cables for charging cell phones or other electronics depends on the quality of their components, but also on how they are used and stored. A lot of people end up having one in reserve, so they don’t run out of battery when least expected.
The tangle of wires can also be a nuisance, in addition to the need to always have an outlet available.
To try to solve these problems, smartphone manufacturers have been betting on wireless charging. It uses induction energy transfer, a technology derived from an ancient process developed by Croatian inventor Nikola Tesla. Just plug the charger into the socket and bring the phone closer.
If you want to try this option, but don’t know how to choose, check out some tips:
loading pattern
There are few wireless charger standards on the market. The most famous of them is Qi, a nomenclature used by companies such as Apple, Samsung and Xiaomi, among others. You can also find technologies like A4WP and PMA Powermat.
There will hardly be any compatibility issues, as cellphone manufacturers default to Qi. But anyway, it’s worth researching this before buying the accessory.
power
You can find models ranging from 5W to 20W. This variation impacts the price of the product and recharge time. If the budget allows, prefer chargers with more power, which allow you to recover half of the battery of some smartphones in up to 30 minutes.
Base
Loading ways can change from one model to another. There are chargers that activate the battery by approximation – in these, you need to leave the cell phone on a tray on the table. In others, it is necessary to dock the phone in a vertical base. Some have a kind of magnetic hook, which attaches to the device.
An important point: the charger base must have the same power as the source connected to the outlet. Want an example? The Apple model has 15W, but it must be connected to a source of equal or greater power for this capacity to be reached.
battery life
There is no consensus on the impact of wireless charging on battery life. Manufacturers claim that there is no risk if the charger follows the correct specifications.
But a study from the University of Warwick, England, pointed out that this type of charging can make the batteries get hotter than desired. In lithium-ion batteries, such as cell phones, this could shorten their lifespan.
Here are some popular models with good reviews from consumers.
