S220HS 2.1 Channel Bluetooth Amplifier Board - High Power TDA7498E

In this review of the S220HS 2.1 Channel Bluetooth Amplifier Board, the bottom line is straightforward: this board is for DIY builders and small-system audiophiles who need high peak power and flexible inputs in a compact package. The reviewer found the dual TDA7498E chips deliver noticeably strong output for small home or portable systems, and the ability to rename the Bluetooth device and set a password through an app provides real-world convenience and security that many budget boards lack.

Key Features

• TDA7498E HIFI Chip: Dual TDA7498E power amplifier chips supply robust peak output suitable for bookshelf or portable speaker projects.
• Wide Voltage Range: The board runs from DC 12-38V, giving flexibility to match different power supplies and battery setups.
• Multiple Input Methods: Bluetooth, 3.5mm AUX, and USB inputs allow easy connection to phones, laptops, and MP3 players without extra hardware.
• Upgraded DC Socket: Gold-plated 5.5 x 2.5mm high-current connector prevents loose connections and reduces risk of sparks during use.
• Bluetooth Customization: You can change the Bluetooth name and set a password via the app, which helps avoid accidental pairing and improves security.
• After-sales Support: The vendor offers 7x24 customer service for troubleshooting and warranty questions, which is useful for DIY builders.

Who It's For

The S220HS suits hobbyists building compact home audio setups, portable speaker systems, or simple car audio projects that need a powerful 2.1 output and flexible inputs. Its wide voltage window and peak power figures make it a good fit where higher SPL and bass support are desired from a small board.

It is less suited to users who expect finished consumer electronics with cases, display screens, or plug-and-play consumer simplicity; installers who need certified automotive hardware or rackmounted professional amplifiers should look at purpose-built alternatives.

Pros & Cons

Pros

• High peak power output from dual TDA7498E chips gives strong headroom for small systems.
• Bluetooth, AUX, and USB inputs cover most source devices without adapters.
• Custom Bluetooth name and password via app improve convenience and privacy.
• Sturdy gold-plated DC socket for reliable power connection on 5.5 x 2.5mm supplies.

Cons

• Sold as a bare amplifier board so buyers must provide their own enclosure and suitable power supply.
• Peak power is quoted as PMPO; sustained RMS output will be lower in real use.

Our Verdict

The S220HS is a practical choice for DIYers and small-system builders who want a compact, high-peaking 2.1 amplifier with modern connectivity and Bluetooth security options. It offers strong value when paired with a proper DC supply and enclosure, but buyers should expect to handle installation and not rely on quoted PMPO as sustained power.
