I am literally lost for words, this is amazing. I have been running usb fans ontop of the radiators to move heat around better, it's worked beautifully and now my home doesn't heat up at the last minute before bed it's warm and welcoming when I get in from a long day and really need to be cosy. These run the usb fans all day and have the ability to charge a phone, run usb devices like mifi and usb lights (I didn't do it at the same time, although it's possible) I solike it because it's so compact, when your heading out the door and you notice your phone doesn't have charge it can easily fit in your handbag / backpack etc with ease and charge it up for you on the go! No more bulky power banks weighing your bag down.
I have had power banks in the past most of my usb lights run off them, most are great this however for the capacity it incredible. It lasts longer than I anticipated and the price is outstanding.
I highly recommend this to anyone needing a power bank for a low drain high usage item like a usb fan or lights. You won't be disappointed infact you'll be amazed
