Power banks that have low power capacities are among the most used type of power banks. And this is because when a power bank has a low power capacity, it means that it’s going to be smaller.

Overall, the power capacity of a power bank and its size are directly correlated. Even though a Mini power bank can only charge a smartphone about 1 or 2 times and only have a single charging port. These small power banks hold most of their value with the fact that you’re able to take it anywhere you want to.

This is the Shinngo 6,700mAh power bank that is similar to power banks just like the Jackery Bar Premium and also in some ways different because it uses an LCD power capacity display that most power banks with its capacity simply don’t normally use.

Power Capacity:

This Shinngo power bank starts with a power capacity of 6,700mAh and since it has only a single charging port, the conversion of this power bank is going to be average or at times it can be better than average depending on the charging speed that you’re using with the power bank.

3.7 x 6,700 = 24790 / 5 = 4,958mAh

So during charging, you’re losing about 2,000mAh of power capacity and that’s going to leave with you about 4,900mAh of usable power that your devices are going to be able to use.

It’s with this Output power capacity that it makes the most sense to use this Shinngo power bank for smartphones because it’s just enough to accommodate the smartphones in the best way possible.

This is because even the higher capacity smartphones like the Galaxy S7, iPhone 7 Plus, or the Google Pixel can charge to their full power at least once with this power bank.

Even after charging once to their full power, those smartphones can leave leftover power that can be used later just in case you need it. So if you have smartphones that a battery capacity of 1,500mAh then you can very well charge that type of smartphone to its full power at least twice.

Size and Weight:

In Mini power bank terms this Shinngo power bank is on the higher spectrum because its power capacity is still quite large and that means the power bank is going to be larger than most Mini power banks. Or least larger than most power banks that you consider to be Mini in size.

Functional Components:

Almost all of the functional parts of the power bank are on a single side. This is where you’ll find the USB charging port, the Micro-USB Input port, flashlight, and the LCD power capacity display.

On the side of the power bank is where there’s the power button. Also, the sides of the power bank are where there are depressions on each side which makes it easier to hold the charger.

The LCD power capacity display shows 3 digits and it’s an overall better way of reading the power capacity than just a couple of dots that most power banks use. The power button does have a few usages as you’re able to turn on the LED flashlight by double-tapping it and you must press the power button to begin charging.

However, this Shinngo power bank is highly reliable with its ability to charge most smartphones about 1 or 2 times and it has an Output and Input charging speed that stands at 2 Amps.

The usage of an LCD power capacity display is very useful because it gives a more accurate reading of where the power capacity is at so you’re careful about using the power capacity and recharging it in time.
