Batteries powered glue guns
Batteries
— powered by replaceable elements of a standard size, for example, "finger" AA.Such power supplies are usually not included in the kit, they must be purchased separately. On the other hand, batteries are cheaper than branded batteries, they are available in a wide variety of brands and even types (there are both disposable and rechargeable cells). Another important advantage can be the ability to quickly replace dead batteries with fresh ones. However, by the standards of glue guns, this type of power supply does not differ in either power or battery life. Therefore, there are quite a few battery-powered models, and they are all compact, low-power devices designed for small amounts of work.
