[EX Q]: This is the second power bank I bought in past two month. The first one turns out the capacity is too big to travel by air. I got this one under 10000mAh. Tested a couple of times. Works great. Built in cables very convenient. Comes with a storage pouch good for travel.
[EX A]: positive

[EX Q]: I used them one time and pulled them out of my phone and wire went everywhere and now they do not work. Biggest waste of money and would cost me more to send back.
[EX A]: negative

[EX Q]: I ended up sewing the patch onto my jacket but it might have had something to do with the fabric of the jacket. I'm not sure. The iron on started peeling from the corners almost immediately. It looks great now it's sewed on. I haven't washed the jacket yet so I don't know if that will effect the patch.
[EX A]:
positive
