Best USB chargers on the market: Our favorites

With the accelerated evolution of new technologies, our gadgets demand more and more from batteries. To meet this demand, it is essential that USB chargers offer an even better performance. Here is a list of some of the best models on the market.


Buying Guide

It may seem like a simple mission to choose a USB charger, but with some technical terms involved, it is important to understand a little more about them so as not to end up with an obsolete or delayed charger.

In our buying guide we will show you more information and details to help you not get confused and find a model that really meets your expectations.

What is a USB charger?

USB is an acronym in English that means Universal Serial Bus. In good Portuguese, it is most famous for being a Universal Port for connecting peripherals, such as printers, to computers, replacing the standards used until then.

Developed in 1995, it even reached the market in 1997 when the major brands started to adopt this standard. Initially it was mostly used for data transfer, but today it is best known by shippers.

Since then, it has gained updates and new formats continue to emerge, making them even faster and more reliable. They are also getting smaller, like the microUSB, ideal for smaller peripherals, like cell phones.

What are the advantages and disadvantages of a USB charger?

USB chargers offer several advantages as they can be connected to an outlet or external batteries. They also work for data transmission and are simple, requiring no additional configuration, making the whole process quite intuitive.

However, there are also some disadvantages. In some cases it is necessary to use adapters, since constant updates quickly make the models obsolete. And, if you opted for a cheaper model, you may find that they take a long time to recharge.

What are the different types of USB chargers?

Technology always has its advantages and disadvantages and it is common for products to evolve quickly. It is no different with USB chargers, which have spanned several generations.

The most used are still the Micro USB connectors, present in most cell phones and which is based on USB 2.0 or 3.0 and sometimes drives us crazy trying to find the right side to make the fitting.

The Lightining format is best known among Apple users, as it is an exclusive feature of the company and based on USB 2.0, offering higher transmission speed.

Finally, USB-C is still looking for space in the market and promises to last, since it fits anywhere, it is more compact, faster and easier to use. Unfortunately, it is not yet compatible with many devices.

How much does a USB charger cost?

The price can vary widely according to technical specifications and even the number of outputs available on the charger. The most traditional, outlet models, can be found for around R $ 5 to R $ 15.

Models with more outputs, reinforced wires and higher loading speed usually range from R $ 15 to R $ 30, with a few models costing more than that.

Where to buy a USB charger?

You can find cell phone chargers at stores specializing in electronics and technology. It is also very easy to find them at cell phone dealers, a great option if you have lost your charger and are looking for an original and reliable replacement model.

It is also very easy to find them on the internet, either in online stores you trust or in large distributors like Amazon, which delivers the product to your home with all the security you deserve.

Purchasing criteria: What to consider before buying a USB charger

As you can see throughout our article, choosing a USB charger may not be so easy with so many options and new models popping up all the time.

So, we separated some more technical criteria for you to analyze before making the purchase and not end up regretting or having to resort to adapters that end up impairing performance.

  • Wire size
  • Device compatibility
  • Loading speed
  • Portability

Carefully review the topics below to find a good charger and never have to go to your friends again to charge your phone when the battery hits 5%.

Wire size

It may seem trivial, but when you consider that we will often recharge while we are still using our cell phones or tablets, wire size is critical.

And, don’t worry, no matter how big the wire, it doesn’t interfere with speed. Just be careful when handling it, keep it from bending too much or forming a tangle. That way you don’t have to sit next to the outlet.

Device compatibility

With new generations of USB emerging, compatibility is one of the most important factors when choosing your charger. If possible, do a test or check the manufacturer’s specifications carefully.

In addition, some brands like Apple have exclusive models. Fortunately, USB 2.0 standards are still the most widely used and virtually universal.

Loading speed

At this point we will enter a little into the technical specifications of the products, such as their amperage and power. First of all, you would probably roast your phone by plugging it directly into the outlet, so the proper connector is critical.

It is he who controls the voltage that is used in charging so as not to damage the product. Currently, the voltage is usually 5V, with a minimum amperage of 2A.

Another factor that you will notice are the Wattz, which range from 10 to 15W. This is also a factor that influences the loading speed, so the higher the better.


A few years ago it would be difficult to imagine that we would have the capacity of huge computers in the palm of our hands, with increasingly advanced models coming out every year.

Unfortunately, batteries are the ones that suffer most in these processes, as they are increasingly required. That’s why USB chargers are so important. Whether connected to a conventional outlet, vehicle models or even using an external battery, evaluate which one offers the greatest benefit for your needs before closing a deal.
