Very practical Power Bank

The Bank holds power, what was promised in the description. But I still only given 4 stars because I found two drawbacks in the year.

1 point: The EasyAcc Power Bank is still very difficult in the backpack.
2nd point: The EasyAcc Power Bank needs too long to recharge.

So I wanted to buy myself a lighter Power Bank as this for here. B. EasyAcc 3000mAh Power Bank. Well, I was lucky that I got just paid a Power Bank. Clearly, this has only 3000mAh and not 10.000mAh, but I need this for the one-year practice only for my smartphone and not a tablet.
