Fire alarm systems need to be inspected, tested and tagged annually. Testing must include all smoke detectors, manual pull devices, annunciators, visual indicators and strobes, control units, voice/alarm communications systems and any other devices that are a part of the fire alarm system.
it will need a port like this one to get more power from the usb since it only give 5.0 volts and this powered usb give up12 to 24 volts so you dont have that in a laptop and there is no way it could raise the power on the usb port in a laptop without damaging something .http://en.wikipedia.org/wiki/Powered_USB.
If you measure the Supercharger to Grip charging voltage on a USB-C break out, you will see a 12V charge voltage. The only way the charge voltage can be something other than 5V is to negotiate that voltage in software using the PD protocol. I can say with 100% certainty that the Grip is PD.
