The chargers of the different technological devices have become an indispensable complement at this time. Any baggage worth its salt gives you top priority when traveling.

At home, if the family is moderately large, the occupation of sockets is notable. However, the expansion of wireless advancements is making these tasks much easier.

In this context, qi chargers move. Among those analyzed, we first highlight a 7.5 W model from the Yootech brand for its comfort, performance, and economical price.

In short, wireless or induction charging is an efficient and convenient way to charge devices without the need for cables.

What is Qi?
Qi is a standard accepted by more than 200 world-class technology companies that provide the user with easy and safe wireless charging.

It also guarantees full compatibility for all those devices that have the Qi logo.

What products are compatible?
For example, all the high-end models from Apple and Samsung. We refer, as examples, to the iPhone 8, 8 plus, and X or the Samsung Galaxy S8 or Note 8 and Galaxy S9 and S9 Plus.

In the case of the South Korean brand, it is one of the most compatible models since they started with the Galaxy S6.

  • Google also has terminals compatible with the Qi standard, in the case of Pixel 3 and 3 XL and later. These are just a few examples.

    How does it work?
    Its operation is based on electromagnetic induction. We try to summarize what it consists of in the following steps:

    A signal is emitted from the base through a transmitter coil.

  • This signal looks for its receiving counterpart in the Smartphone mechanism.
  • When the two are linked, the electromagnetic induction process begins.
  • Electricity (or flow of electrons) begins to circulate in the transmission coil.
  • This circulation generates a magnetic field that is identified by the electrons in the receiving coil.
  • The flow of electrons from the receiving coil begins to circulate due to the magnetic field.
  • That circulating electricity in the receiving coil is what charges the device.

    Inductive or resonance?
    The difference between one type of wireless charging and other lies solely in the distance.
    Inductive: It requires physical contact between the device and the charger in addition to having the charging coils of the smartphone itself and those of the charger aligned and connected.

    Resonance: Keeps the phone, charger, and charging coils close together without touching.

    The inductive one is much safer as it reduces the risk of cramps when the devices are in contact.

Another advantage is that while the resonance load reaches a maximum of 7 V inductive it offers up to 15 V.

Advantages of wireless mode
Accessibility:
It is as easy to charge as to leave the mobile on a table since the base can be located anywhere. That is, if, for example, you have a couple of chargers, you can take calls at home and leave the device on the charger between one and the other.

Protection: These chargers also preserve the terminal against wear and tear caused by frequent connection and disconnection of cables. It is much stronger than charging cables that end up deteriorating.

Comfort: We have already pointed out some advantages related to this aspect. As comfortable as leaving your smartphone on any site as you pass. Without using more than one hand and using tenths of a second.

Speed: This accessibility and comfort do not detract from its speed since it is comparable to a conventional charger.

What to keep in mind
Compatibility:
Without a doubt the most important factor to take into account. Check first if the wireless charger is going to work for your mobile.

 

Standards: In this section, note that the most popular is the Qi that is analyzed here, but it is not the only one.

There are other charging standards such as PMA that allow higher electromagnetic fields, but it is less efficient than Qi.

The Watt up allows you to charge devices that are up to a distance of five meters from the charging base.

Finally, we point out the Fast Wireless Charging developed by the Samsung brand that, as we have pointed out, in certain models is compatible with Qi.

Power: Improves unstoppably as, to date, taking longer to charge than its wired counterparts has been the biggest drag on wireless devices.

 

At present, and in the case of Qi, that disadvantage has been reduced to a minimum as we have already advanced. It should be remembered that this standard can load with up to 15 W of power, although the usual range is 5-10 W.

Design: With its greater penetration in the market, its design has diversified. We can distinguish three great options:

Dock: Support that allows loading horizontally and vertically. It is always in view and is already offered with designs to integrate them as a decorative element, for example, in imitation stone.

Base: More compact and with the disadvantage that you cannot see at a glance what reaches the screen while it is charging.

Carpet: Undoubtedly the most practical for charging several devices at the same time, although, as in the case of the bases, there is no information while charging.

By car: There are wireless for the car with ideal support to go on a trip with guarantees of not running out of charge.

Overcharging: Not a problem for cordless phones as they can remain operational after charging without diminishing their lifespan.

Yootech 7.5 W: Efficient and economical
YootechIt works very well in contact even with a silicone case, although better if it is removed, with a very fast start of charging. Very easy to use, just check that it is placed in the center, and very comfortable as well as economical. To get an idea of ​​the charging speed, and its proximity to cable chargers, in a quarter of an hour it can reach half of a smartphone placed with just 5% charge (it also depends on the mobile model).

It comes with an anti-slip rubber and a built-in light that turns on when charging turns off after a few seconds or flashes if an incompatible device is inserted.

It has three charging powers depending on the smartphone you have (it is essential to consult in detail all the models it supports).

Its technological development allows it to have temperature control, protection against light voltage surges, or short-circuit prevention mechanisms.

Vcloo 3 in 1: For Apple fans
Vcloo 3
A different alternative. Within a range of very small and light devices, it is an exception because it is more bulky since it has a multipurpose nature (iPhone, I watch, and Airpods).Simultaneous charging for these three devices in a model that, of course, is more expensive without excesses. Although any smartphone compatible with Qi can be charged, it is clear that it is aimed at Apple fans.

The component that recharges the watch is very practical since it comes with a magnet and not in the base, which makes it more comfortable since it is not necessary to use the cable.

Very practical and with a design that looks great. It charges very well and avoids the clutter of cables, much more appreciated when it comes to charging three devices at the same time.

The system of small lights that it carries can be annoying if it is left to charge at night, but you have to know that it can be removed by pressing a button.

Nanami: Charger and stand

An alternative with a base that places the mobile as on a lectern to charge it correctly. In normal mode, the complete would be around three hours.

Sober and elegant design inspired by a wind surfboard, although the upper edges are too pointed. The light always stays on, although it is not annoying.

The advantage of these designs is that in addition to loading, they can serve as a support to watch a video comfortably.

In short, an alternative with an optimal value for money, versatile, and very suitable if you are not looking for an ultra-fast charge as a priority.

Te-Rich 15W: Colorful and comfortable
Te-Rich 15WA charger that may well look like an elegant and discreet decorative element. Its upper face of glass with a mirror effect and its matte edges give it a lot of showiness.

It detects the mobile in any position, which is not a minor detail as it further accentuates its comfort. Ideal for those who always take into account the aesthetic factor.

CHOETECH Wireless ChargerOne of its biggest attractions is in the price. It performs its functions very well with a reasonably fast charge and without unusual heating.
