• This is a palm-sized charger that can be easily used instead of a power generating rod for experiments such as charging the foil of an electric meter.
• When the lever of the main body is pressed toward the object, it can be charged positively, and when the lever is released, it can be charged negatively.
• Since it can also be used as a static eliminator, it can also be used conveniently to remove static electricity when measuring chemicals.
