Replaceable Battery

— it can be both rechargeable and non-chargeable batteries. This type of power supply allows you to work autonomously, and even in complete “separation from sockets” — the main thing is to have a supply of batteries at hand. In addition, the batteries are quick and easy to change, unlike the built-in battery (see related paragraph). The main disadvantage of such a power supply is the need to regularly buy batteries or pay a fairly large cost for rechargeable batteries.
