I need some suggestion for portable vacuum that has a decent suction power so I could use it for general cleaning around my place but it should also be gentle enough to cleaning the inside of my PC.

In case you are wondering, I do have a great cord powered vacuum cleaner but it’s kinda heavy and I can’t use it to clean the inside of my PC. I am also aware of the risk of static electricity charge from vacuum ruining PC component but I never experienced such thing before.
