Its not all perfect thoughhas one annoying quirkdefect there is a button that when you press it lights up leds letting you know how much battery is left as one led has 25 written next to the other 50another 75and finally 100 but for some reason i always have to press that button make the battery start charging a plugged in device if i just attach my phone or bluetooth they wont start to get charged until i pressed that buttonand i have to do this every time i plug and unplug any device to charge from this battery although you only have to press the button once every time you connect it and as long as you dont disconnect the device you wont have to press the button again even if the device charges for a few hours

You will know its charging by having the percentage leds light up and one of them will start and continue to blink while charging an attached device the whole time it is charging so if an device is plugged in but no lights are blinking on the battery it is likely not changing the attached device

To charge your device press the button and a light should start blinking and your device will start getting charged

My only complaint is that in the product description and on the box it says that it is a fast charging battery pack but when i plug it into my note 5 it just says that it is only cable charging not fast charging

The only issue i had and the reason that i left out one star was because the cord included did not work with my iphone 6s

Could be another defective product

One huge problem to begin with is that they have no instructions or any info what to do and what to expect
