Battery powered sterilizers

 

— powered by replaceable batteries of a standard size — for example, "finger" AA or "little" AAA (the specific size should be specified separately in each case). Just note that batteries are usually not included in the kit; however, this configuration has its advantage — it allows you to choose the batteries at your discretion. You can even buy rechargeable batteries and not spend money every time on fresh batteries. In itself, such power, on the one hand, makes the device independent of sockets and allows you to use it even on the road; on the other hand, batteries produce very little power and are not suitable for steam sterilization, or even for use in heaters. As a consequence, this type of power is found exclusively in portable UV sterilizers.
