Each year, every mobile phone provider showcases something new about their product. In recent years, instead of improving their phone’s battery life, they have focused on providing fast-charging batteries instead. It has become a trend since 2015, and people love the chance of charging their mobile phones faster than ever before. Thanks to fast charging mobile devices, anyone can always be on the go with a fully charged phone.
In this article, we’ll show you how a charger works depending on its specifications. With this knowledge, you’ll have a better understanding of which type of charger you prefer before making a purchase.
Here’s what you should keep in mind. Voltage multiplied by the current is equal to power. Therefore, if you want to increase your battery power, you need to increase either the voltage or current.
To classify as a fast charging technology, you need to have:
- High voltage and low current
- Low voltage and high current
Understanding How They Work
In this section, we’ll look into some popular fast charging technologies and understand each function.
High Voltage and Low Current Chargers
Many USB 3.1 devices follow the USB Power Delivery (USB-PD) specifications, which include using a maximum power output of 20V/5A (100W). Not all smartphones bring out that much power, and most phones under this category even exceed the given parameter. That’s why some of them can recharge your phone in just minutes instead of hours.
1. Mediates Pump Express
MediaTek’s Pump Express 4.0 is a charging innovation that promises to reduce your phone charging time into half. It is created for the USB-C cable standard and can provide up to five amps of charge current. You can charge wired devices, but they also have an option for wireless charging. You don’t need any special cables for this technology, and you’d get your phones charged just in time that you need them.
2. Qualcomm Quick Charge
More Android phones nowadays use the Qualcomm quick charge technology. It adopts the high voltage, fast charging standard. It will release its Quick Charge 5 by Q3 of this year, which is said to be the fastest commercial charging solution in the world. The Quick Charge 5 can charge up to 50 percent of the battery in just five minutes and a full charge under 15 minutes without sacrificing any of its safety features and accessories. What makes it great is that Quick Charge 5 leverages the existing USB PD-PPS chargers (meaning, your usual USB Type-A and USB-C).
Low Voltage and High Current Chargers
Phones under this category increased the amount of current allotted for high power charging rather than increasing their voltage.
1. Huawei SuperCharge
A Huawei phone with 3,000 mAh capacity can reach 48 percent of charging in five minutes. That speed is ten times faster than regular batteries. It has a max power of 40W and a voltage of 5/9/10V by using standard USB cables. Huawei claims that the more efficient charging method is getting your power voltage closer to the battery cell’s energy, instead of increasing the voltage and keeping currents at standard.
2. OPPO 125W Flash Charge
This charging technology by Oppo can make your battery charge up to 41 percent in five minutes and fully charged in 20 minutes. The technology supports the charging mainstream protocols of 125W PPS and 65W PD. It supports a charging scheme of up to 20V 6.25A, meaning increasing its power density without the need to increase the charger size. The technology also added temperature sensors to enhance safety protection during the charging time.
Each charging technology functions differently; that is why it is essential to know which charging technology is compatible with your phones. Knowing so will help you find the right charger to maximise your battery life. From the cable to the voltage you use, each contributes to how fast your phone charges.
