Question: 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.

Answer: positive


Question: Only looks good in the picture, and the materials are very rough, stained and cheap. The copper is a lining not pure. I should’ve know due to low price but even at the price it is definitely very poor workmanship and not worthwhile. Now I have spend more money getting something better so as they say; better to spend wisely then hunt for bargains.

Answer: negative
