Audiotek Output 12A Amp Mobile 13.8V DC Power Supply - Reliable 12V

In this review of the Audiotek Output 12A Amp Mobile 13.8 Volt DC Power Supply, the bottom line is simple: it is a straightforward, no-frills regulated DC supply for anyone who needs a stable 13.8V feed for 12V equipment. The reviewer found it best suited to hobbyists, installers, and technicians who power CB radios, HAM rigs, scanners, mobile auto sound systems and similar devices. The single biggest reason to buy is its consistent regulated output and screw terminal convenience that make installations quick and dependable.

Key Features

• 12 AMP Regulated Output: Delivers steady current up to 12A so connected 12V devices run reliably under typical loads.
• 13.8V Nominal Voltage: Provides the higher 13.8V output expected for many radio and communications systems to maintain proper operation at full load.
• 110V Input Compatibility: Plugs into standard 110V mains for home or shop use without special wiring.
• Screw Terminal Connectors: Heavy duty screw terminals make it easy to attach wiring securely for installations or bench testing.
• Short Circuit Fuse Protection: Built-in fuse protection helps protect the supply and attached gear from overloads and shorts during installation or operation.
• Wide Device Support: Rated to power cellular phone chargers, CB radios, scanners, HAM radios and auto sound components with a common 12V requirement.

Who It's For

This power supply is aimed at home users, radio hobbyists and installers who need a compact bench or mobile supply that provides a regulated 13.8V and up to 12A of current. It is especially useful for powering communications gear, bench-testing amplifiers and running small auto audio systems where a reliable DC source is required.

Users who need ultra-quiet, fanless operation for RF-sensitive lab work or those requiring industrial-grade fire resistance should look elsewhere or verify environmental ratings, since customer feedback included mixed notes on noise and at least one report of a unit experiencing a serious failure under unknown conditions.

Pros & Cons

Pros

• Reliable regulated 13.8V output provides stable performance for 12V radios and electronics.
• Solid build with heavy duty screw terminals that simplify wiring and installation.
• Good value for the power provided, with customers noting consistent voltage under load.
• Short circuit fuse protection adds a layer of safety for field and bench use.

Cons

• Noise level drew mixed feedback, so those with sensitive RF gear should verify suitability for their setup.
• At least one buyer reported a failure with fire implications, so installations should follow safe mounting and fuse practices.
