Fast charging, flashlight The developer writes that it has 10000mAh, but he could hardly charge the phone only once. When opening the case, it turned out that it contains 3 batteries of 2000mAh each, that is, a total of 6000mAh.  Oleg Kruchinin: use Hoco B20-10000 more than year |
I recommend something better.. It seems to be not bad, but there is a but... 20000 mAh should charge the phone 6 times, well at least 5, but alas 2 times if you're lucky... use Hoco B20A-20000 month or more i recommend it should buy |
Design If you don't put it in the box carefully enough, the flashlight will turn on and at the most interesting moment it will turn out that the battery is dead.  Anna Serednytska: use Hoco B20A-20000 few months |
Hoco B20-10000 is a spare tank, ready to come to the rescue for "refueling" gadgets, as they say, in the field, when access to the outlet is not expected in the near future.
capacious tank
The first thing that captivates a mobile battery is a tasty price tag. Especially in light of the claimed capacity at 10,000 mAh. Of these, over 6500 mAh is available for charging gadgets. The rest is lost in the process of converting the voltage from 3.7 V on the batteries of the external battery to the standard USB bus voltage (5 V). Also, part of the energy is lost along the way when the Power Bank is heated and exposed to low temperatures.
Tandem ports
Both ports of the mobile battery output current up to 2.1 A. The gadget “refuels” its tanks via the microUSB input. By the way, in the company of interface connectors, there are two bulbs of a built-in flashlight, which can be useful in the dark (when going out into nature, returning home along dark alleys, etc.).
Head up
Indication of the remaining battery charge of the model is displayed on the digital screen as a percentage. It harmoniously fits into the plastic body of the device, decorated with carbon. The only complaint about the “bank” is the excessive thickness of the case (24 mm). On the other fronts equal to the battery, you still need to look carefully. In the low-cost price range, the Hoco B20-10000 rules the roost virtually single-handedly, towering over its closest rivals by a whole head in terms of functionality.
