Sanwood Technology: Fortify the Safety Line of Power Banks with Professional Testing Equipment

As power banks have transformed from "optional accessories" to "essential daily carry items," market demands for them have evolved from simply "being able to charge a device" to "absolute safety and reliability." For enterprise, compliance is the bottom line for survival, while reputation is the the sharp key for breaking through. And all of this begins with whether a product can withstand professional testing before being put into use. Sanwood Technology's environmental simulation testing equipment can help companies conduct reliability tests on their products in accordance with standards such as GB 31241 and UN38.3, avoiding quality risks from the source.

I. Safety Crises

Several typical safety incidents in recent years have revealed common challenges in the industry:

Air Transport Risks: A certain brand of power bank experienced thermal runaway in a low-pressure cabin environment, leading to an emergency landing.

Extreme Climate Failures: Products fail to output power normally in low-temperature winter environments, or the outer casing overheats and deforms during high-temperature summer use.

Transportation Damage: Internal solder joints detach due to vibration and impact, causing short-circuit hazards.

The root cause of these accidents is often not a single component failure, but rather a systemic failure of the product under the stress coupling effect of complex environments.

II. Standards System

Faced with increasingly stringent market regulations and consumer expectations, the national standards system has built a crucial line of defense for the safety of power banks:

GB 31241-2014 "Safety Requirements for Lithium-ion Batteries and Battery Packs for Portable Electronic Products" it sets comprehensive safety requirements from the cell to the finished product. The standard covers multiple key testing items, including environmental safety testing (adaptability to low pressure, temperature cycling, etc.) and mechanical safety testing (extrusion, vibration).

UN38.3 "Test Standards for the Transport of Dangerous Goods" serves as a passport for products entering the global market. The standard includes eight stringent tests, such as altitude simulation, thermal testing, vibration, and mechanical shock, simulating various extreme situations that may be encountered during transportation.

III. Solutions 

Under such stringent standards, Sanwood Technology, based on its in-depth understanding of industry standards, provides a series of professional solutions:

Altitude Test Chambers

Temperature Range: -70℃～+150℃

Pressure Range: Atmospheric Pressure~4.4KPa

Verifies product reliability in high-altitude areas and air freight scenarios;

Evaluates the impact of rapid pressure changes on product sealing and safety valve performance.

AGREE Test Chambers

Temperature Range: -70℃~+180℃

Humidity Range: 20%RH~98%RH

Accurately simulates and simultaneously applies temperature, humidity, and vibration stresses, meeting the stringent requirements of UN 38.3 T.1 to T.4 and multiple environmental adaptability tests in GB 31241.

In addition to the above equipment , we also offer professional testing equipment such as High and Low Temperature Chambers,Battery Test Chambers, and Rapid-Rate Temperature Change Chambers. From simple temperature shock to complex comprehensive stress screening, our equipment matrix aims to help companies build a one-stop internal reliability testing laboratory, firmly grasping the initiative in quality control.

IV. Conclusion 

Sanwood Technology provides not just individual testing equipment, but a complete reliability testing solution. There are no shortcuts to safety, and quality requires proof. Let us use our professional testing capabilities to build a solid foundation for the safety and reliability of enterprises products.
