Stylish and inexpensive
The Chinese brand Hoco at one time started with the production of cases for smartphones and tablets, then expanded the range with cables and adapters, after which it also started producing power banks. Usually, their models are distinguished by their appearance. For example, small batteries look like a cartridge with lipstick, others are painted like a tree or camouflaged. However, the hero of today's Hoco B31-20000 review is more likely to gravitate towards classic forms, although its design cannot be called boring: grey rough plastic with inclined grooves, the ends are highlighted with yellow inserts, an oval of the same colour highlights the power button on the side.
Soft touch
The battery is soldered in soft-touch plastic, pleasant to the touch, which fits comfortably in the hand. The dimensions and weight of the Hoco B31-20000 cannot boast of being particularly miniature: it turned out to be very overall, but for some reason it weighs less than its competitors with the same capacity — only 330 g. Therefore, it is more convenient to carry it in a backpack or bag. It will also fit into a jacket pocket, but it will clearly stick out of it. However, capacious batteries are not designed to be carried in pockets; there are more miniature options for this.
Low efficiency
All controls and connectors are located on one of the ends of the external battery. We are talking about a microUSB port and two full-sized USB ports (for charging the device itself and third-party gadgets, respectively). 2.1A output current allows you to fully charge a modern Xiaomi Mi 9T caliber smartphone with a 4000 mAh battery in about 3 hours. Theoretically, for this option, the claimed capacity of 20,000 mAh is enough for exactly 5 seconds of charging, but in reality, the usable capacity is much lower and is somewhere around 14,000 mAh, which is enough for 3-4 full charges of an average smartphone. Yes, on the one hand, this is a very low efficiency, on the other hand, the price is still tempting.
