About the weak current feel on the aluminum case
17
In some very special case some people could feel very weak current
on the aluminum case
The reason for this phenomenon is due to the electromagnetic
interference suppression component in AC adapter which built a
necessary circuit between the primary and secondary
This weak current is controlled within the limits of security standards
required of and the production of this product in the factory have
passed the strict quality inspection so you can feel free to use it
