  • LCD Power Capacity Display

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 basically 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 off 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 are able to charge to their full power at least once with this power bank. Even after charging once to their full power, those smartphones are able to 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.
