The AN/PRC-77 entered service in 1968 during the Vietnam War as an upgrade to the earlier AN/PRC-25.It differs from its predecessor mainly in that the PRC-77's final power amplifier stage is made with a transistor, eliminating the only vacuum tube in the PRC-25, as well as the DC-DC voltage converter used to create the high plate voltage for the tube from the 15 V battery.
The Universal Power Adapter for Mobile Devices (UPAMD), codename IEEE 1823-2015 (before approval P1823), is an IEEE standard for power supply design intended to cater to the power range of 10–130 W (optionally 240 W) for mobile devices like laptop computers.
The increasing need for international travelers to use their laptops as well as access the internet created a demand for electrical adapters, converters, and telephone adapters. While today most electronics are dual voltage 100-240V and capable of handling electricity worldwide, previously many of them needed a voltage converter.
A common use of the voltage converter is for a device that allows appliances made for the mains voltage of one geographical region to operate in an area with different voltage. Such a device may be called a voltage converter, power converter, travel adapter, etc.
IEEE P1823 was a proposed global standard for a universal power adapter for mobile devices (UPAMD) that require between 10 W and 240 W. E.g., Laptops, larger tablets and other mobile devices that can require much more power than the (non-Power Delivery) USB battery charging specification limit of 7.5 W at 5 V. [25]
