When buying, carefully inspect the battery, if it is swollen, then do not take it. Sotmarket sells devices with expired batteries, and judging by the reviews on the Web, it is not alone. If it is possible to check when buying - if a squeak is heard during charging, then the battery is dead and does not charge. Initially, it is not charged and, according to the instructions, it should be charged initially for 6 hours . Like a fool, I listened to a squeak for 6 hours, then when I saw that it was not working by googling, I realized that it was a dead battery.
