The global AC-DC power supply adapter market revenue was around US$ 12 billion in 2023 and is estimated to reach US$ 24.1 billion by 2032, growing at a compound annual growth rate (CAGR) of 8% during the forecast period from 2024 to 2032.
AC-DC power supply adapters, also known as AC-DC converters or wall warts, are electronic devices that convert alternating current (AC) power from a wall socket into direct current (DC) power that can be used to power a variety of electronic devices. These adapters are commonly utilised in a wide range of applications, including charging smartphones and laptops, as well as powering small appliances and electrical devices. An AC-DC power supply adapter's principal role is to convert the high voltage and alternating current supplied by the power grid into a lower voltage and direct current that suits the requirements of the item being powered. A sequence of electronic components such as transformers, rectifiers, and voltage regulators are used to accomplish this conversion.
Factors Influencing Market Growth
- The demand for efficient, low-voltage, high-current processors is increasing. This is increasing the demand for AC-DC power supply adapters, ultimately expanding the market.
- With the advent of digital transformation and automation for AC-DC power supply adapters, the demand for AC-DC power supply adapters will increase, thus driving market growth.
- The rise in innovations in 5G Internet of Things, electric vehicles, and other electronic devices is expected to increase the demand for AC-DC power supply adapters, thus propelling market growth.
- A surge in mandatory safety standards and compliance with regulations may hinder market growth.
Impact of COVID-19
COVID-19 has given the market opportunities as well as challenges. The pandemic brought to light how important a robust power infrastructure is for enabling remote work and other critical services. It became clear to prime vendors that investing in robust electrical systems, like high voltage and current integrated circuits (ICs), was necessary to ensure a steady flow of power. The growing emphasis on resilient infrastructure is creating opportunities in the market for AC-DC power supply adapters.
