How to Find the Right Fast Charging Electronics for Your Phone?

Fast charging is the newest buzzword in the mobile industry, and almost every flagship smartphone launched this year came with some fast charging technology. Unfortunately, this has led to a lot of confusion about which fast charger you should buy for your phone and whether or not it’s worth investing in.

Fast chargers can bring your battery from 0 to 100% in as little as 30 minutes. However, there are different kinds of fast chargers, each with pros and cons. For example, some fast chargers are more affordable than others, while some are more portable than others. Others might offer other valuable features, such as an LED light when you need to charge your phone in the dark. While all fast chargers are essentially the same, not all of them work with every phone.

Therefore, checking whether your phone supports fast charging is essential before purchasing a new wall charger. However, there are multiple fast-charging standards available right now. If your smartphone is manufactured by a different manufacturer or model, you may need to buy a different type of fast charger to get optimal results. Fortunately, there are quite a few third-party manufacturers that produce universal fast chargers that work with most phones on the market today. In this article, we’ll discuss all things related to buying the right fast charger for your phone.

Understanding Fast Charging

Before we jump into the details of fast charging, it’s important to understand the working of your phone’s charging circuitry. In general, when you connect your phone to the charger, it draws power from the source at a rate of 5 volts at 2 Amperes. This charging current is then converted and adjusted based on your phone’s circuitry to provide the necessary power. The charging circuitry inside your phone consists of a few components, including a voltage regulator, a current controller, and a trans resistance (resistance to current flow) element. Most modern phones have a charging circuitry that allows for variable power input between 0 and 5 volts at 2 Amperes. This means your phone’s charging circuitry can take between 0 and 5 volts at up to 10 Amperes of current. Basically, your phone is designed to accept any amount of power from 0 to 5 volts.

Quick Guide to Fast Charging

Fast charging is a feature designed to rapidly charge your smartphone. The charging is done at a higher voltage, which results in a higher current flow compared to standard charging. This increase in current flow causes a decrease in charging time. Most smartphones support fast charging, and manufacturers have designed their own versions based on a few different charging standards. The most popular standard is called Pump Express. Other standards include Quick Charge and USB Power Delivery. The latter is USB-standard charging and the most efficient, but smartphones do not widely support it. All fast chargers are wall chargers with a higher power rating than standard chargers. Fast chargers work with a standard voltage of 5 volts, but you’ll get a current flow of 10 Amperes. This will result in faster charging times.

Which Fast Charger Should You Buy?

The best way to find the right fast charger for your phone is to check if it’s compatible with your device. You can do so by checking two things: the voltage and current rating of the charger and your phone’s charging circuitry.

– Voltage and current rating: To charge your smartphone faster, you need a wall charger that can provide a current flow of 10 Amperes or more. This will allow your phone to draw more current, charging the phone faster. Most smartphones support 5 volts at 10 Amperes, but some may support up to 12 Amperes.

 – Charging circuitry: The other thing to check is your phone’s charging circuitry. Your phone’s charging circuitry has been designed to accept power from a 5-volt source. Likewise, most smartphones are designed to accept a current flow of 5 Amperes from a 5-volt source.

USB-C Chargers

The USB-C standard has become a common standard for both charging and data transfer for a variety of smartphones. Many fast chargers are available that use USB-C connectors. These chargers allow you to charge multiple devices, like your laptop and smartphone, much faster. The only downside is that you need to buy a charger supporting your device. You can find a list of compatible USB-C fast chargers on Apple Electronics’ website. To find the right USB-C charger, you need to check the voltage and current rating of the charger. You also need to check the USB-C connector type on your device to make sure they match.

Wireless Charging Chargers

Wireless charging has become a popular option with many smartphone users. Fortunately, some wireless charging pads come with a built-in fast charger. When choosing a fast charger for your wireless charging pad, you need to check the voltage and current rating of the charger. Most wireless charging pads charge your phone at around 5 volts at 2 Amperes. You can also check the charging circuitry inside your phone to ensure it’s compatible with a wall charger producing 5 volts at 2 Amperes. Finally, check the wireless charging chargers Apple Electronics recommend.

Main Specification You Should Check

There are many specifications that you should check on a fast charger before you purchase it. The most important one is the maximum charging current, which is also the most difficult one to find. Most companies don’t give this information, and even if they do, it’s extremely difficult to interpret. Other important specifications include input voltage, output voltage, and output current.

The maximum charging current indicates how fast the charger can fill up your battery. Chargers with higher maximum charging current are more efficient, but they also tend to be more expensive. The input voltage indicates the range of voltages that the charger can accept. The output voltage and output current indicate how much power the charger can provide to your device. All of these specifications are important, but the maximum charging current is the most important one to look at.

Since each phone has different power demands, there are no hard and fast rules about what fast charger to buy. However, for a safe choice, look for one that has:

  • A high input voltage of at least 12V.
  • A high output voltage of at least 5V.
  •  A high current output of at least 10A.
  •  Protection against overheating and overcharging.
  •  A warranty period of at least 12 months or more.


Fast charging is an excellent feature that will allow you to charge your device faster. However, you need to buy the right wall charger to get the most out of this feature. The best way to find the right fast charger for your phone is to check if it’s compatible with your device. You can do so by checking the voltage and current rating of the charger and your phone’s charging circuitry. All fast chargers are wall chargers and come with a higher power rating than standard chargers. Fast chargers can be a life changer if you often find yourself with a low battery at the wrong moment.
