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.
The big sell for most users is going to be faster charging. Type-C can deliver power at up to 100 watts at 20 volts. This means that larger devices can now be charged from USB, including laptops and monitors. Say goodbye to the clunky AC adapters we've been lugging around until now.
