Not a FAN. I do like powerbanks. I HAVE ALOT OF THEM. i let this bad boy charge for 12 hours..... thought it was changed but i guess it didnt completely. only charged the phone 15% should have been more with a full charge. and it GOT HOT. they power5bank its self. just from charging my phone. that is a concern for me bc its new and should not be getting super hot. i do love the size bc it fits right in my purse. but...... Hot and purses.... i dont like i dont need a fire. but other then that i like it
