Power banks can have high power capacities but can still be low quality because there are other aspects of a power bank that you to consider that make it all come together into a complete package. For example, there’s the charging speed which is how you actually experience the power bank, the size, and weight or other features such as how the power capacity is displayed. The reason that a portable charger is portable in the first place is that it has a power capacity but the surrounding parts are what builds up to a good or bad experience.
This Villain 20,000mAh power bank is quite famous on Amazon and it sure has a lot to boast about with its power capacity, and powerful charging. Let’s see what it really has to offer and if any of it is of any value.

Power Capacity:
The power capacity of this Villain power bank starts at 20,000mAh and along with its charging speeds, the conversion rate of this charger is mostly going to be average. The reason for that is because it doesn’t have very fast charging speeds, but we’ll get more into detail about that later. For now, though, I will say that one USB port has a charging speed of 5V/2.1A and the other port has a speed of 5V/1.0A.
Using both of them at the same time can make the conversion of power slightly worse but for the most part, the conversion of power is going to be quite average.
3.7 x 20,000 = 74,000 / 5 = 14,800

|
---|---|---|---|
iPhone SE | 14,800mAh | 1,624mAh | 13,176mAh Left Over 9.1 Full Charges |
iPhone 6 | 14,800mAh | 1,810mAh | 12,990mAh Left Over 8.1 Full Charges |
iPhone 6 Plus | 14,800mAh | 2,915mAh | 11,885mAh Left Over 5.0 Full Charges |
iPhone 6s | 14,800mAh | 1,715mAh | 13,085mAh Left Over 8.6 Full Charges |
iPhone 6s Plus | 14,800mAh | 2,750mAh | 12,050mAh Left Over 5.3 Full Charges |
Samsung Galaxy S6 | 14,800mAh | 2,550mAh | 12,250mAh Left Over 5.8 Full Charges |
Samsung Galaxy S6 Edge | 14,800mAh | 2,600mAh | 12,200mAh Left Over 5.6 Full Charges |
Samsung Galaxy S7 | 14,800mAh | 3,000mAh | 11,800mAh Left Over 4.9 Full Charges |
Samsung Galaxy S7 Edge | 14,800mAh | 3,600mAh | 11,200mAh Left Over 4.1 Full Charges |
Apple iPad Mini 2 | 2,479mAh | 6,470mAh | 8,330mAh Left Over 2.2 Full Charges |
Apple iPad Mini 4 | 17,500mAh | 5,124mAh | 9,676mAh Left Over 2.8 Full Charges |
So you’re going to be able to use a 14,800mAh Output power to charge devices.
This power capacity is going to be most useful when it comes to charging smartphones regardless of what the smartphones is. Since high capacity flagship smartphones such as the Galaxy S8 or the Google Pixel are able to charge to their max power about 4 times to their full power with this Villain power bank.
If you’re charging a smartphone with a low capacity such as the iPhone SE or even an iPhone 7, then they’re able to charge to full power about 8 times if the Villain power bank starts off at a full power capacity.
Power Capacity for Tablets
Then when it comes to charging tablets it does a pretty good job to charge them to full power too. Mini tablets such as the iPad Mini 2 or 4 are able to charge to their full powers about twice. Even an iPad Air 2 can charge to its full power twice if the power bank starts off from a full charge.
Output Charging:
There is two Output charging ports on this Villain power bank and unfortunately, the charging speeds on each of the ports are different. One USB port has a charging speed of 5V/2.1A and the other port has a charging speed of 5V/1.0A. This is a problem because if you’re charging two devices at once, there’s always going to be a device that is charging slower than the other, and that would be the one that is charging with the 1.0A USB port.
With that said, this is a common mistake that many power banks have and in this case, you’re always going to want to use the 5V/2.1A port first for faster charging speeds.
Input Charging:
The power bank is recharging through a single Micro-USB Input port and it has a max recharge rate of 5V/2.0A. To charge the power bank as fast as possible you should use a 2 Amp USB wall charger or higher to recharge the power bank as fast as possible. A full recharge can take 7-8 hours so it’s best to recharge this power bank while you’re sleeping.

Design
Size and Weight:
It’s quite a large power bank with it having a 6.4 inches in length, a width of 3.2 inches, and a thickness of 0.8 inches. It has a weight of 1.1 pounds. So you can still take this portable charger anywhere but most of the time you’re going to want to set it down and use it.
Functional Components:
On the short side of the power bank is where there are two USB ports and two LED flashlights. The on one long side is where there’s the Micro-USB input port and on the opposite long side is where there’s a power button.
You must press the power button to begin charging and the power button is also used to turn on the flashlight by double tapping it and double tapping it again to turn it off. On top of the power bank is where there’s a convenient LCD screen that shows the power capacity and also the Output charging speed that the ports are doing.
Build
Structure and Material:
The Villain power bank is built quite well as it has a plastic bottom and the siding of the charger is made of metal. It’s a not a Rugged power bank, but the charger is tough enough for light bumps and shortfalls.
Tech:
The tech with this Villain power bank is quite good as it has safety protections to keep you and your devices safe during charging.
Reliability
On the reliability front, the reliability waivers with its different parts. The reason for that is because it has a good power capacity, however, the Output charging speeds aren’t very good. It might have a large size and heavy weight but it can still be taken anywhere that you want.
We think that the Villain 20,000mAh power bank is the basis of a high capacity portable charger is supposed to be with its capabilities but it doesn’t do anything extraordinary to make itself better.

Summary:
Power:
The power capacity goes through an average conversion rate and that’s what makes it able to charge many devices multiple times over. However, the charging speed could use some work because one port is 2.1A and the other port is 1.0A.
Design:
It’s a large power bank that is also heavy. Most of the time you’re going to want to set it down. The good part about its design is that it has an LCD screen at the top that can show the power capacity and the Output power.
Build:
The build quality is standard and is perfect for everyday use.
Reliability:
It’s a reliable enough power bank but you shouldn’t have too many high expectations for it when it comes to the charging speed because that’s where it falls short.
