It just straight out does not work I put the right batteries in it and it does absolutely nothing but but then again it wasn't that expensive so so I kind of figured it wouldn't anyway

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.
positive

Like other reviewers have said, this product is NOT what is pictured here. Very disappointed. There is a distinct difference in how the two products work.
