I have this Lenovo 20V - 2A laptop adapter, I would like to know if it's ok to use with my Razer Blade Stealth?
Razer Blade Stealth (RBS) came with 20V - 2.25A power supply.
No, for one simple reason: 250mA difference.
You must never ever use a power adapter that is rated less than the original for the device.
If the Lenovo was rated 2.5A then there wouldn't be a problem....
