Today's smartphones are awesome with beautiful and bright screens. But these beautiful and bright screens take a lot of juice from the battery. It's hard to do a day with one charge. For times when you know you'll run out of battery, Cooper Cases have this nice sleek Power Card Pro Universal Smartphone Portable Powerbank.
It's a 1000mAh power pack that fits inside you wallet. So you are always sure to have extra juice to make it to the end of the day.
Made of nice aluminium, it's very premium looking in silver which is the color I chose.
There is no need to carry a USB cable because it has a built-in MicroUSB output. I find this very convenient because I always misplace my charging cables. Doesn't help that I have two boys with tablets who are constantly taking them...
Now with 1000mAh you will not fully charge your smartphone from a dead battery. You will however have enough power to make it to the end of the day. For my Samsung S7 it's like an extra 50% battery life. Which is fine by me and exactly why I chose this small power pack instead of the larger 20000mAh which I also have but use when going somewhere for a few days and not know when I'll have access to a power outlet.
For everyday use as a back up battery, this Cooper Case is perfect.
