Very good the product. Has approx. 420g, then you will feel the weight on it in the backpack etc. It comes with a USB Type B cable to charge, but it has how to use Type C to do the same function.

The shark is good, never failed, rather heavy, but if you take into account how much it charges, it is very normal. In General, I am satisfied.

Enough for 2 charging the phone with a capacity of 4500, a little more remains. Charges slowly. In principle, a good charger, the only very strong smell of burning.

Good appearance, the power bank is made soundly. But there is probably no 20000 in it. Most likely something about 14-16000. After a full charge, I charged from It 2 times the phone with the 4300 battery and once the tablet with the 3500. Incorrectly shows the charging indicator. I drove sharply from 3 divisions to zero, while charging for 2 days with 4 indicators. In general I recommend to the purchase. He costs his money. Delivery in Russia is very fast. Until the Saratov region 3 days, received "five" at the checkout. In general-solid 4.

Like that it turns on itself when the phone is connected to it. On most others you need to press a button, this one itself recognizes the load. The rating is reduced due to the fact that the real capacity is very different from the declared one, according to my measurements by the tester, about 13000ma. I understand that absolutely all manufacturers overestimate real values, so to speak I was ready for this, but I expected at least 15000 m.
