Power Converter

What Is a Power Converter?

Power converters are essential electrical accessories that bridge the gap between your vehicle's onboard power system and the everyday devices you depend on. Power converters work by transforming one type of electrical current into another — most commonly converting AC (alternating current) household power to DC (direct current) automotive power, or vice versa. Whether you're parked at a campsite on shore power, outfitting an RV, or running a mobile electronics system, having the right power converter ensures your equipment gets the clean, stable voltage it needs to operate safely and reliably.

How Power Converters Work

Most vehicles operate on a 12-volt DC electrical system. A power converter acts as a translation layer, stepping voltage up or down and switching between AC and DC as needed. For example, a common automotive use case involves converting 110-volt AC shore power down to 12-volt DC to run in-vehicle monitors and accessories without drawing on the vehicle's own battery. This is especially valuable for RV owners and fleet operators who want to keep cameras, displays, and safety systems running while connected to external power.

It's important to distinguish between a power converter and a power inverter. While an inverter converts DC to AC (letting you run household appliances from your car battery), a converter does the reverse — taking AC power and delivering stable DC output suitable for automotive electronics. Many vehicle accessories, dashcams, backup camera systems, and safety monitors require a steady 12V DC supply, making a properly matched converter a critical part of any installation.

Key Considerations When Choosing a Power Converter

• Voltage compatibility: Confirm input and output voltage ratings match your power source and the device you're running.
• Amperage rating: Choose a converter with sufficient current capacity for your equipment — a 3-amp unit suits most monitors and small electronics, while larger loads require higher-rated models.
• Application: Shore power setups (RVs, boats) benefit from wall-plug converters, while permanent installs may need hardwired solutions.
• Protection features: Look for overload protection and stable output regulation to guard sensitive electronics from voltage fluctuations.
• Form factor: Compact plug-in converters are ideal for portable or temporary use; panel-mount units suit permanent installations.

Brandmotion Power Converters

Brandmotion is a Detroit-based automotive technology company with deep roots in vehicle safety and mobile electronics integration. Brandmotion's power converter lineup, such as the ACCY-WMOP, is purpose-built to complement their advanced camera and monitor systems — allowing users to run Brandmotion displays on AC shore power without draining the vehicle battery. This makes their converters a natural companion to any Brandmotion AHDS wireless monitor installation, whether in an RV, truck, or fleet vehicle.
