The material covering the power bank is very pleasant to touch and it does not feel like a low-quality product.
This power bank supports the next ports- 2 USB ports, 1 type-c port, and a micro USB port, on the other side, one of the USB ports supports fast charging.
Performance
The ROCCO is built for safety and has a build-in smart hybrid protection system, a 9 layer system (Overcharge, over current, reset, over-discharge, voltage-surge, temperature, power-surge, anti-reverse, short-circuit protection.
If will charge a smartphone or any device that supports those USB ports, basically anything. I used the fast charging slot to charge my Lenovo P2 and everything worked like a charm. If you using an 18W charger to charge the power-bank. it will take you around 7 hours to fully charge it.
By using a 5v 2a charger it will take around 13h and by using a 5v 1a charger it will take 24hours.
Thank to the little LCD screen you are able to monitor the battery level and also see the charging voltage.

My Opinion
Its the first time I have been using a power bank and I could not see any place for it. Oh boy, I was wrong ! most of us use phones or laptops every day, what if you really need to charge your phone or laptop or any other electric device and you don’t have any electricity nearby?
Well your basically out of luck if you don’t have a power bank.
It saved me so many time, works well and cost little.
The only issue I had is with its weight, not so lightweight but does everything it supposed to do and really saves me when needed.
