[EX Q]: Clip is smaller than OEM, they also don't expand nearly as well as the original and don't have a relief cut into them for easy removal... Half the installed clips have fallen out in less than 500 miles so I guess that relief isn't really needed. These are far less superior that the OEM clips. Buyer beware, you get what you pay for...
[EX A]: negative

[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
