Type of power
After you decide on which memory you should choose, you should pay attention to the type of food. There are two types of power: batteries and built -in battery. The batteries are no longer relevant and left the market. Buy a player with a battery. Such players are very compact and comfortable. The only minus is that the battery must be charged from a socket or from a computer. However, if the battery is high -quality, then it can work up to 200 hours in active mode. This means that 10-20 days of permanent work are provided.
