Potential Issues With Unstable Voltage for Retail POS System

February 2, 2024

To ensure the smooth operation of your retail POS system, we recommend using the dedicated power adapter provided by Sunany while using Sunany retail POS system to ensure the stable voltage. Unstable voltage can lead to the following issues:

1. System Crashes: Voltage fluctuations may cause the retail POS system to crash, resulting in interruptions in operations and potential data loss.

2. Hardware Failures: Unstable voltage can damage internal hardware components of the retail POS system, such as the motherboard, memory, and screen, rendering the device inoperable.

3. Data Loss: Voltage fluctuations may lead to data corruption or loss, negatively impacting the normal functioning of the retail POS system.

In order to avoid these issues, we encourage Sunany clients to use Sunany’s power adapters specially designed for retail POS systems. They are manufactured by CWT (, a well-known power supply manufacturer in Taiwan. They have passed the world’s mainstream certifications and can provide stable power supply to ensure that the equipment is in operation. Reliable operation in any environment.
