Power banks are indispensable accessories in daily life, and the selection of their performance parameters is particularly important for users. In this article, we will use UGREEN’s power banks as examples to provide an in-depth analysis of the three key specifications of power banks and portable chargers: capacity, output, and input.
Understanding Capacity in Power Banks (mAh)
mAh is the unit that is used to measure the capacity of a battery. In theory, the higher the mAh, the more charge it can store and ultimately provide you when it comes to the power banks. UGREEN has many options, starting from a 5,000 mAh charger all the way up to 25,000 mAh.
The bigger the charge capacity, the longer it can charge your phone. However, many brands are chasing the mAh number but forget the quality of their products, which results in bad results like overheating or damaged devices. But if you choose a reputable brand such as UGREEN which comes with all the safety features like charging protection, you will never harm your phone, nor bring their battery life down.
Output (Voltage, Current, and Power)
In a power bank, the output is how it delivers energy to your device. The output voltage is the voltage supplied by the power bank to charge a device. Voltage is basically the electrical pressure that pushes the current and it is measured in a unit called Volts.
Interestingly enough, most power banks operate at a voltage of 5V, which makes it a standard. However, some devices might require a voltage of 12V like laptops and more. Next, we have Ampere a MilliAmpere. This unit incorporates how fast a power bank will charge your device.
A higher current means a faster charger. For example, a power bank with a 2A capacity will output a charge much faster than 1A. So, if you need to charge your device quickly, consider choosing a power bank like UGREEN 100W 20,000 mAh power bank as it can charge phones, tablets, and even laptops.
Lastly, we have power which is measured in Watts. Power is when you combine both voltage and current. Moreover, a 5V/2A power bank typically charges at 10W. Similarly, a 5V/3A portable charger charges at 15W, offering faster charging.
All three of the output units are quite important and help you in charging your devices optimally. So, in general, choose a power bank with a good output speed and safety features.
Input (Voltage and Current)
But now, we must understand the importance of input in the world of power banks. Input is basically how fast a power bank charges. All of UGREEN’s power banks charge quickly and can be charged at a fairly quick rate.
For example, the UGREEN Foldable Kickstand Magnetic charger charges at a speed of 20W, charging it up quickly so you can use it for your personal case. Just like we mentioned in the output second, power banks need energy to charge too.
Hence, you should choose a power bank that can charge at least faster than 10W, depending upon its mAh size.
How to Choose the Right Power Bank
Now that you understand all the basics, how to choose the right power bank? For that, you must understand the input and output of the devices. Ask yourself, do you value a bigger reserve of power bank that you want to use to charge your devices quickly?
In that case, choosing a 20,000 power bank will be ideal since that can charge both your phone, and your laptop at a fairly faster rate. However, there’s another issue. If a portable charger has the necessary capacity but will still charge slowly, what’s even the point?
That’s where UGREEN’s bundled products come like the UGREEN 100W 20000mAh Power Bank that comes with a 100W charging speed and a data cable that can charge at the same rate.
This power bank itself can charge at a fairly faster rate of 60W, which will help you use this product to its maximum potential without breaking the bank. On the flip side, if you value less capacity, you will be greeted with a better size.
UGREEN provides many wireless charging options that quickly charge your devices with their high power delivery and build quality.
Conclusion
Understanding power bank specifications allows you to choose the right product. You should always go for a product that will not only give you the specifications, but also a good warranty, and the perfect product to charge your devices.
