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:
Bought this in February 2018 and it's June 2018 now, stopped working overnight. Unfortunately for me I am in Europe now and don't know if I'll be able to get it replaced. Worked great when it was working and now it doesn't charge and when I plug in the cable to charge my phone through the case, it says a ridiculous amount of time until fully charged.
answer:
negative

question:
Reads like a novel. Engrossing. Great insight into the characters involved. Really get to know them - particularly their motivation on both sides - spies and spy catchers. Backdrop to John Le Carre's Tinker Tailor Soldier Spy.
answer:
positive
