Quick Charger Power Bank 10,000mAh for Mac Book and Samsung

This is a lifesaver! There were a lot of times that I need my phone badly and it would just be battery empty when I am out of the house. Not very often that there is an available outlet around to use to charge my phone. Most of the time I go to hospital and take an hour train ride to and from the hospital and my phone would just die when I need it the most. Just recently my phone's battery drains out too fast and I need to recharge it immediately. Good thing I saw this product which is not too pricey compared to other power banks. I bought a power bank a year ago and after a week, it is already useless. that is why I was hesitant to buy another one. But this power bank looks very promising. I love that it is light weight that I can easily fit it in my purse without feeling the weight. It charges the phone easily. I haven't tried it with my macbook yet(I still need to buy the cable :)) but generally this is a great buy! It is worth it!
