S220HS 2.1 Channel Bluetooth Power Amplifier Board - High Power 2.1

In this review the S220HS 2.1 Channel Bluetooth Power Amplifier Board is judged as a budget-friendly, high-power option for hobbyists and DIY home audio builders who need flexible inputs and strong output capability. The single biggest reason to consider it is its raw power potential driven by dual TDA7498E chips, which promise hefty peak outputs and the ability to run mid-size speakers and a powered subwoofer when paired with an appropriate power supply. It is best considered by those who can accept some variability in sound refinement for the tradeoff of power and connectivity.

Key Features

• TDA7498E Chip: Dual TDA7498E chips deliver the amplifier's main power advantage, making it capable of driving bookshelf speakers and a subwoofer with substantial peak power.
• Multiple Input Methods: Bluetooth, 3.5mm AUX and USB inputs make it easy to connect phones, tablets, laptops or MP3 players without swapping hardware.
• Wide Voltage Range: The amplifier accepts DC 12-38V, giving flexibility to run from different power sources including 12V and 36V adapters for different power needs.
• Upgraded DC Socket: A gold-plated, high current 5.5 by 2.5mm shielded socket reduces sparks on connection and improves reliability for frequent use.
• Custom Bluetooth Options: The unit supports custom Bluetooth name and password settings, which help manage multiple Bluetooth sources in shared setups.
• After-sales Service: The manufacturer advertises 7 by 24 customer support for troubleshooting or quality concerns, which is useful for DIY users.

Who It's For

The S220HS suits DIY audio builders, hobbyists and small home theater tinkerers who want a compact, high-power 2.1 amplifier module with flexible inputs and the option to power larger speakers or a subwoofer. Its wide input voltage range and multiple inputs make it practical for projects that will use different power supplies or source devices.

It is not for listeners seeking studio-grade fidelity or plug-and-play reliability without tinkering; some customers reported mixed reliability and occasional units failing. Buyers who need guaranteed long-term durability or precise sound tuning should consider more established, higher-end integrated amplifiers.

Pros & Cons

Pros

• Strong peak power capability from dual TDA7498E chips suitable for driving mid-size speakers and a subwoofer.
• Multiple input options including Bluetooth, AUX and USB for flexible source connection.
• Wide DC input range (12-38V) allows use with different power adapters and setups.
• Gold-plated high current DC socket reduces sparking and improves connection reliability.

Cons

• Some users report inconsistent reliability and a few units failing early, so quality can vary.
• Sound refinement and protection details are limited compared with more expensive, purpose-built amplifiers.
