Core Features

🔋 Reliable Power Backup:

Delivering a stable 5.1V 6000mA power output, the X1205 ensures uninterrupted performance for resource-heavy tasks

and multiple peripherals, providing a dependable power source at all times.

📊Smart Power Management:

The X1205 intelligently monitors the Raspberry Pi's power status,

automatically cutting off power when Pi 5 is shut down to conserve battery life.

Its ultra-low standby mode optimizes energy usage and extends battery lifespan.

🛡️ Seamless Power Switching and Data Protection:

Equipped with AC power loss and adapter failure detection, the X1205 instantly switches to backup power during outages, protecting your Raspberry Pi from unexpected disruptions. It also supports seamless data backup by integrating with storage devices, safeguarding valuable data even during power failures.

🖥️ Convenient Automation:

The X1205 supports auto power-on, enabling automatic boot-up when power is restored. It also allows full software-controlled power-off for safe and hassle-free shutdowns.

⚡ Fast Charging Support:

With up to 3000mA fast charging, the X1205 quickly recharges to maintain readiness for backup power needs.

🏗️Stackable Design:

Designed to mount underneath without using the 40-pin header, the X1205 supports easy stacking with other Raspberry Pi accessory boards, offering versatile expansion options.

Safety Instructions & Warnings

It is essential to read and understand these safety instructions and warnings before charging your batteries.

• Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the instructions below may result in fire, personal
  injury, and damage to property if charged or used improperly.

• Never make a wrong polarity connection when charging or discharging battery packs. Always double-check the polarity of the
  battery's connector to ensure that "+" is connected to "+" and "-" is connected to "-".

• 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.

• Keep the UPS shield away from children to ensure their safety.

• Do not apply power to your Raspberry Pi via the Type-C USB socket.

• Do not use 21700 battery with built-in protection circuit.
