Coolreall 15600mAh Power Bank

As you will recall I recently reviewed a 3 USB port power pack from a company called Coolreall.  Well I am at it again this time with a slightly smaller version.  The power pack I am reviewing this time is the Coolreall power bank 15600mAh and has 2 ports meaning it is able to charge 2 items at the same time.  In comparison to the other power pack this one is slightly smaller in size and weighs a little less too so it’s easier to carry in a hand bag as it’s not quite as weighty.  This is a more practical power bank to take if it’s travelling in a handbag.  The power bank is again black and has the same sleek design and can be used with most popular smart phones and tablets.

Inside the box as with the coolreall 20000mAh power bank I had everything I needed to get the power bank charged so I could take it on my travels this included the power bank, a micro USB cable and instruction booklet.

The 4 LED lights on the unit show the charging progress of the power bank and when it is not being charged you can press the small button at the side and these lights will come on to show you the power level.  There is also a torch light which can also be turned on and off using the same button and comes in handy should you need a torch or are using the device somewhere that is dimly lit.


The power bank has a high capacity and can charge an iphone 6 up to 6 times, a Samsung Galaxy S6 4 times or an ipad mini 2 times.  Sounds useful doesn’t it especially for long car and aeroplane journeys.

This power bank detects and delivers the optimal charging current for any connected device to ensure the fastest and most efficient charge which is very useful when you need a device in a hurry.  As with the coolreall 20000mAh power bank there are 5 built in safety mechanism to prevent over charging over-discharging, over-voltage, over-current and short-circuit protection which is reassuring to know.

You can take a look at the power bank here:


This is a great item to have at hand when you are out and about especially in cases of emergencies as it’s just typical that our batteries are going to be running low when we need them.  I like to avoid problems and keep my phone charged as much as possible but with a hundred and one other things to do each day it isn’t always easy to remember so having some form of back up can be very helpful.
