Power Adapter Yongnuo EA11012E-1900 — 19 V 5 A, DC plug 5.5×2.5 mm

The Yongnuo EA11012E-1900 power adapter supplies a stabilized 19 V DC output at up to 5 A through a standard 5.5×2.5 mm barrel plug. Packaged as a compact external brick, this adapter is intended to provide a reliable mains-to-DC conversion for photographic and electronic equipment that accept a 19 V supply and the specified connector. The design balances portability for field use with stable performance for desktop setups.

Advantages

The adapter delivers a consistent 19 V output and supports currents up to 5 A, suitable for devices with moderate power demands. Its 5.5×2.5 mm DC plug is a common size for many monitors, LED lighting units and camera accessories, enabling straightforward compatibility where the connector and voltage match. The external-brick format keeps footprint and heat dissipation manageable during continuous operation.

Suitable for

• Powering LED video lights and continuous lighting panels that accept 19 V input
• Supplying power to field monitors and small studio monitors with a 5.5×2.5 mm barrel jack
• Running camera accessories or control units designed for a stabilized 19 V DC supply
• Powering small electronic devices or chargers that match the voltage and connector dimensions

Key specifications

• Output voltage: 19 V DC
• Maximum output current: 5 A
• Output connector: 5.5×2.5 mm barrel plug (center positive)
• Form factor: external brick (desktop/portable)
• Intended use: mains-to-DC power conversion for compatible devices

How to use

Connect the adapter to a suitable mains socket using the included mains lead, then insert the 5.5×2.5 mm plug into the device's DC input jack, ensuring correct polarity and a secure fit. Verify that the target device specifies a 19 V DC input and can accept up to 5 A before connecting. After use, disconnect the adapter from mains power and remove the DC plug from the device to prevent standby drain. Allow adequate ventilation around the adapter during extended operation to avoid overheating.

Usage recommendations

Check device voltage and polarity requirements before use, and avoid using the adapter with devices that require different voltages or connector polarities. For continuous or high-load operation, provide space for airflow and periodically inspect the cable and connector for wear. If uncertain about compatibility, consult the equipment manual or a qualified technician.
