know how to choose phone charger it is currently something crucial, after all, since last year, the issue of chargers not coming in the smartphone box has gained strength and unfortunately is here to stay. With smartphones becoming more and more advanced in processors, cameras and especially in new technologies of artificial intelligence, having a good battery is essential. Although having a giant battery doesn't always mean performing well in this area, as it needs to be in line with system optimization and other factors. 56203l
With good technologies involving the way of charging, we have options where smartphones are charged in less than 30 minutes to 100%, even if this is still a minority. To help you understand every detail of chargers and how battery charging works, we made this article with all the details you need on the subject.
How does smartphone charging work? 4m2ag
In summary, we can say that each smartphone has a battery and each of them delivers energy more or less similarly to each other. Scientifically, we initially have two electrodes — one positive and one negative — and an electrolyte (substances that generate positive and negative ions when heated, such as sodium, potassium and others).
This process of ion generation This is what makes our smartphones charge, after all, they leave a positive input (socket, for example), go through the charger (where the electrolytes heat up) and finally arrive at the negative input (your smartphone connector).
In the case of recharges, what happens is that the batteries of lithium, used in smartphones, unlike a conventional battery, allow the process explained above to occur several times. When the battery is discharged, this chemical process causes electricity to be produced and when recharging it, the chemical process absorbs energy.
And how does fast charging work? 4i1x5u
Maybe you were just like meme from Nazareth after all this explanation (because I stayed when researching the subject), so to simplify things a little, before talking about fast charging, let's explain how charging works in everyday conversation.
When we pick up a plug adapter, the used on it are volts, amps e Watts. The volts measure the voltage, the amps the current of energy and the Watts are a measure of electrical energy. To find the wattage of a charger, all you need to do is multiply the value in volts by the value in amps.
Check the data of 15W Android charger below:
The higher the result in Watts, the more powerful and faster the charge will be. In the photo above you can see an example of an 18W charger with variable power. In this case it has the possible outputs: 5V and 3A=15W, 9V and 2A=18W or 12V and 1.5A=18W. The maximum power of the charger is 18W, but these differences in Volts and Amps make the smartphone stay safe and not overheat or explode.
We currently have some chargers that reach speeds of over 100w, allowing a full charge in less than 30 minutes, but they are still a novelty. In this matter, the most important thing is to understand this exchange of ideas between Volts, Amps and Watts to generate enough energy for a quick charge.
types of chargers 4c3h3x
Now that you understand how charging works, there's nothing better than getting to know chargers. Regardless of the smartphone you have today, the default is USB (except for connectors lightning that Apple insists on using in iPhones and other devices).
USB technology has undergone major changes over the years and thanks to that, today we can use a single cable — USB-C — for connecting the vast majority of devices. This evolution also allows you to charge a smartphone at a slower speed or at a faster speed. super mega fast. Check out:
Conventional charging, USBs and Quick Charge 1m376v
When choosing a charger, the most important thing is to check if it is compatible with the technology Power Delivery, USB-IF specification (USB Implementers Forum, an organization that sets standards related to USB) or the Quick Charge, from Qualcomm.
| USB version | Voltage (Volts) | Current (Ampere) | Max power (in Watts) |
| USB 1.0 | 5V | 0,5A | 2,5w |
| USB 2.0 | 5V | 0,5A | 2,5w |
| USB 3.0 | 5V | 0,5A / 0,9A | 4,5w |
| USB 3.1/3.2 (USB-C + USB – PD) | 5-48V | 0.5A/0.9A/1.5A/3A/5A | 240w |
| USB 4 (USB-C + USB-PD) | 5-48V | 0.5A/0.9A/1.5A/3A/5A | 240w |
The big difference is that with USB-C PD chargers, you will have more compatibility with other devices like laptops. In contrast, the Quick Charge takes advantage of being compatible with all USB standards and not just USB-C, having a system of backward compatibility the same. Check the details of recommended chargers for the main brands below:
lightning v3j3d
Apple is the only one on the list that insists it's not 100% USB-C, but currently ships a cable lightning for USB-C. Now that the craze of no longer shipping chargers in the box has gotten even stronger (I'll get to that later), you'll have to shell out a little money to get an iPhone charger that has the Lightning to USB-C standard. Recommendations for current iPhones are as follows:
| USB technology | Voltage | Current | Maximum force |
| USB-PD | 14,5V | 2A | 96w |
- Apple 18W, 20W, 29W, 30W, 61W, 87W, or 96W standard USB-C chargers;
- A third-party USB-C standard charger with USB-C PD .
Because Apple cables are now all Lightning - USB-C, if you have an older iPhone charger it will work, but it won't deliver. required speed for a quick charge.
Qualcomm Quick Charge z2p1c
The famous Quick Charge produced by Qualcomm is one of the main charging standards in the smartphone industry, especially when it comes to an Android charger. Devices with processors Snapdragon are all compatible with the technology, but the cool part is that it is not unique to them. Any manufacturer can license the Quick Charge power control standard.
| Quick Charge version | Voltage (Volts) | Current (Ampere) | Max power (in Watts) |
| Quick Charge 1.0 | 5V | 2A | 10w |
| Quick Charge 2.0 | 5V / 9V / 12V | 1,67A / 2A | 18w |
| Quick Charge 3.0 | 3,6V to 20V | 2,5A / 4,6A | 18w |
| Quick Charge 4.0 + | 5V/9V (USB-PD). 3,6 to 20V | 3A (USB-PD), 2,5A/4,6A | 27W (USB-PD) |
| Quick Charge 5.0 | 5V/9V (USB-PD). 3,3 to 20V | 3A/5A/>5A | 100+ |
The most popular version currently is the Quick Charge 4.0 +, which can deliver 27w of power and is even compatible with USB-PD. already the Quick Charge 5.0 has the potential to charge 50% in just 5 minutes and a full charge at 15, which is something very surprising. The standard also has an intelligent safety system that prevents the current (amps) from getting higher than necessary, which could lead to shorts and other accidents.
Samsung Super Fast Charging and Adaptive Charging 5k4p4c
The technology Fast Charging é Samsung exclusive and has been on the market for a few years. Adaptive Fast Charging was the most common until the arrival of the Galaxy S10, which already has the Super Fast Charging 1.0. On the Galaxy Note 10 Plus and later models, we now have the Super Fast Charging 2.0, allowing even 45w of loading speed.
| Voltage (Volts) | Current (Ampere) | Max power (in Watts) | |
| Samsung Adaptive Fast Charging | 5V / 9V | 2A | 18w |
| Samsung Super Fast Charging 1.0 | 11V | 2,25A | 25w |
| Samsung Super Fast Charging 2.0 | 10V | 4,5A | 45w |
The first version of Fast Charging was a little slow, taking about two hours for a full charge of the brand's main smartphones at the time (Galaxy S8 and S9, for example), but in the latest versions we already have much more interesting results, managing to charge a Note 10+ in about 1 hour.
One detail is that smartphones and tablets (Samsung), although they are certified with Fast Charging technology, are not exclusive to it, so if you have other chargers with Quick Charge or USB-PD technology, they will work with excellence.
Motorola TurboPower 292ux
the porters TurboPower are the ones that accompany the entire Motorola smartphone line for a good few years. Despite the name, they are certified with the technology Quick Charge 3.0 and guarantee a good result in most cases, reaching up to 28,5w.
| Voltage (Volts) | Current (Ampere) | Max power (in Watts) | |
| Turbo Power 15 | 9V / 12V | 1.2A / 1.67A | 15w |
| Turbo Power 25 | 5V / 9V / 12V | 2.15A / 2.85A | 25w |
| Turbo Power 30 | 5V | 5.7A | 28,5w |
Charging time with an Android TurboPower charger varies by device, but Motorola guarantees around 15 hours of battery life with 15 minutes loading.
Induction charging 6pp44
Wall chargers are getting more and more powerful and efficient, but we are in the era where removing excess wires is the best option. Of course, charging smartphones would not be left out of this new way of working with technology.
Induction (or wireless) charging is only possible thanks to the open interface standard Qi (pronounced TCHI), created in 2009 by the Wireless Power Consortium. The idea of transmitting electricity through the air has been around since the 100th century with Nikola Tesla. Technology has stood still for over XNUMX years and today we have it becoming more and more popular in everything.
How does it work? 6j3466
Wireless charging works by coils of copper, which can generate energy through an electromagnetic field. Generated on a charging base (or “pads”), when the smartphone comes into with this base, an electrical current is generated, where energy is sent to the smartphone's battery.
These “pads” can have different designs and follow the pattern of speed of 15w enough to charge most smartphones without a problem these days, but not as fast as a conventional charger. Here you make an exchange, leaving all the power that a conventional cell phone charger offers, but getting rid of the wires.
Types of induction chargers 6m2l6
As with conventional chargers, in the wireless version, we have a wide range of options and models. An important detail is that whenever you buy a “path” with Qi charging, always check that the product has the Qi certification seal, as these have been tested to avoid accidents.
The most conventional are disc-shaped bases, such as those of Samsung e Xiaomi, but today we also have interesting adaptations such as the MagSafe from Apple, a magnet that sticks to the back of the device, but is very expensive.
In addition, most current smartphones launched with induction charging technology also have reverse charging, that is, they also serve as a base for induction charging.
Power Banks 6d4w5i
We still have the Power Banks, portable batteries that have multiple inputs and outputs, allowing you to charge your smartphone anywhere, as long as it has charge. The Power Banks market involves batteries ranging from 5.000 mAh to 20.000 mAh, ensuring the survival of your smartphone and more people if necessary.
Also, the more robust, the more connections and possibilities, such as Lightning inputs for iPhones and even for inductive charging. As with any charger, it is important that you buy a model already known on the market to avoid accidents or that it does not deliver what it promised.
Do I always need to use an official charger? f1e3g
Knowing how to choose a cell phone charger is important not only for avoid accidents, but also to get the best out of the charging speed on each smartphone. In 2022, when the trend of not sending the cell phone charger in the box has become a standard on the main smartphones, the answer to this question is no, you don't always need to use the official charger for your device.
Although you don't need to use the official charger of your smartphone's own brand, that doesn't mean you should use anything you see around. Use official products from other brands or from outsourced companies that do a good job, as is the case with the Brazilian brand gorilla shield.
And since the question of not having accessories in smartphone cases has been raised, I think this decision is somewhat misguided. I think it could have been something more transparent. This has unfortunately become the new standard, but the good news is that we now have a standard charger, so with just one, you can charge multiple smartphones, even if you switch and the company doesn't send you a new one.
GaN charger 4o145
O Gallium Nitride (or GaN) is a semiconductor chemical element that became more popular after it began to be used in the creation of LEDs in the 90s. The material is expected to replace silicon in several areas soon, one of them, chargers.
According to GaN Systems, a manufacturer specializing in gallium nitride, semiconductor materials rely on what is called band gap (gap band, in free translation), that is, the energetic distance where no electrons can exist. In a nutshell, this band gap indicates how well a solid material can generate electricity. This is where GaN excels at silicon, making the GaN charger more powerful, efficient, and smaller.
We currently have some models of the GaN charger on the market, but they are still quite expensive as they have not yet become the industry standard. The GaN charger, in addition to all the power and stability, promises to be very interesting because it is compatible not only with smartphones and tablets, but also with notebooks. In Brazil, we already have some models with up to 65W of power for about R$200.

Even with the arrival of the GaN charger, not everyone will be able to invest right away in an accessory with this value, so I will divide the recommendations by brand models.
Apple 1b3j2x
Currently, the options available from Apple are these two, but there is one big caveat. despite the MagSafe be very interesting, he is bem salty and amazing, it doesn't come with the power adapter, that is, you would have to buy both or you already have one at home.
My recommendation in this case would be to go straight to a GaN charger, at least you would be paying a higher price for a product that is more powerful and will guarantee good years of use not only for the iPhone, but also for other products.
- Charger for iPhone and iPad 20W Apple – R$ 179,14 at Magazine Luiza;
- MagSafe, the iPhone charger that sticks to the back of your device – R$ 436 in sight at Magazine Luiza.
Samsung 2y6c3s
At Samsung we have more diversified options with slightly more inviting prices, including Power Banks and a pad for induction charging. The Power Bank, on the other hand, despite not being at the best price today, as it has 10000mAh and accepts induction charging, it can be a great choice for those hours of “desperation” on the battery.
Samsung's Super Fast Charging charger will meet the need for all situations with current Samsung smartphones and is well priced. The pad for induction charging, although cool, will only work interestingly if you have a good power supply (a 20W charger, for example).
- Samsung 25W Super Fast Charging Android Charger with USB-C Cable – R$ 119,90 at Americans;
- Fast Charging Samsung Wireless Android Charger – R$159,90 na Amazon;
- Power Bank 10000mAh Samsung with induction charging – R$ 239 at Magazine Luiza.
Motorola 2rd4t
Motorola remains one of the few large companies that still ship the charger in the box. In any case, if there is a need, it offers options for the single purchase of the most varied charger models.
GaN charger and notebook options 6sj25
Lastly, and perhaps most importantly, the charger GaN may be the best choice among all chargers today. Even with its price a little salty, given what it delivers close to conventional silicon, it's worth the investment. Check out some of the most interesting models at the moment:
- 65W GaN charger from Baseus with 3 entries – R$ 243,32 in Amazon;
- GaN charger with 20 Watt fast charging, compatible with iPhone and Android – R$ 119 at Amazon
- Dell USB-C 65W Laptop Compatible Charger – R$183
And so we end our smartphone charger recommendations. We had options with fast charging, induction charging and even the latest GaN charger.
