Abstract

All desktop computers including workstations and servers have internal power supply with DC output of 12 v and 5 v from an AC 110 v/230 v outlet. They do not have a portable AC-DC adapter or an external/internal battery power supply. The laptop computers are powered by internal/external battery or charged simultaneously from an AC 110 v/230 v adapter. Each laptop uses different battery voltages from 10.4 v to 14.8 volts or more, specific to the particular model. The product consists of a combination of three components used as a whole, in combination or as separate individual items/components. The three components are an AC-DC 110 v/ 230 v (30-230 watts or more) adapter with regulated dual DC output of 12 v and 5 v, an AC-DC 110 v/230 v (30-230 watts or more) adapter/charger with regulated DC output of 5 v, 12 v and 16 v and an internal and/or an external low profile DC/DC adapter/converter with variable of fixed DC input of 8 v to 16 v (or wider range) and a regulated multiple DC output of 3.3 v, 5 v and 12 v and/or other regulated multiple DC output voltages. Materials: Hard plastic polymer casing, PCB with components and wiring, DC output jacks. The proposed portable AC/DC adapter 110/230v, of variable wattage, is a new type of AC/DC adapter using 1 or more transformers complete with the circuits for two or more regulated DC outputs and/or a dual DC output of 5v and 12v and a battery charger. A key component is the internal/external low profile DC-DC adapter/converter with variable DC input of 8v to 16v (or wider range) and a multiple regulated variable DC outputs of 3.3v, 5v and 12v and/or other multiple regulated variable DC output voltage combinations.
