This bag caught my eye at Llansamlet tesco as the tag said 'mobile phone charging bag'. Curious, I took it to the cashier and asked her about it as I couldn't find anything electronic on the bag. Out of the front pocket she pulled a very high quality looking portable phone charger and USB lead. There is pockets within the bag that hold your mobile device along with the charger. I bought it in black and cream! Great Christmas gift and a nice bag with a cool use!
