       Product Overview  
 
 

140W PD 3.1 Power Bank & UPS: Dual Output (12V/10A, 5V/12A) for All SBC Devices.

 

The XUPS2 is an integrated UPS and PD3.1 power bank solution designed for single-board computers (such as Raspberry Pi and NVIDIA Jetson), network switches, and industrial or utility applications requiring emergency backup power and power conditioning. It delivers reliable backup power with outputs of 12V/10A, 5V/12A, or a combined total of 120W, ensuring uninterrupted operation even under high-demand setups or when multiple peripherals are connected.

Equipped with an advanced power management system, the XUPS2 intelligently monitors charging voltage and current, as well as UPS output voltage and current via I2C communication. It automatically cuts off power after the host system shuts down to optimize battery life, featuring ultra-low standby power consumption. The board also provides seamless transition between power sources during outages or adapter failures, and supports convenient functions such as auto power-on and AC power loss detection.

Additionally, the XUPS2 supports fast charging at up to 5000mA for rapid battery replenishment. It integrates seamlessly with compatible NVIDIA Jetson platforms for robotics and edge AI applications, as well as with storage systems and industrial controls, ensuring reliable performance during power loss or battery-powered operation. The XUPS2 is an ideal component to enhance system reliability, protect critical data, and maintain continuous operation in a wide range of setups.

⚠

Do not mix and use old batteries with new batteries, or batteries with different brand names.

 
⚠

Lithium batteries have a limited cycle life. Please replace old batteries with new ones when they reach their service life or when   they are two years old, whichever comes first.

 
⚠

When charging the Battery Pack, please place the battery in a fireproof container. Do not leave the UPS shield on wood material   or carpet unattended.
