! ITEM !! DESCRIPTION
|-
| Compatible with||
*Raspberry Pi 4 Model B/3B+/3B/2B/A+/B+
|-
| OPERATING SYSTEM ||
* Raspbian Stretch
* Safe shutdown function tested for Raspbian, other operating systems to be tested and advised
|-
| KEY FEATURES ||
'''Smart Uninterruptible Power Supply (UPS)'''
*Provides continuous operations for up to 10~30hours (depending on battery type and qty used)
*Max 5.1V 8000mA Power Backup for even the most demanding RPi set ups
*Four 18650 Cells Lithium Ion Holder, can work with only two or three or four 18650 Lithium Ion batteries
*Can work with X750-A2 4-cell battery holder to increase battery capacity up to 38400mAh (12 18650 batteries)
*Supports 2A via micro-USB socket or 3A via DC jack fast charging
*Integrated battery protection circuit
*Integrated over current protection and over voltage protection
*Integrated Maxim's fuel-gauge systems (Reading battery voltage and percentage via i2c) - Cabling required
*Integrated 10-A fully-integrated synchronous boost converter
*Intelligent automatic charging and discharging
*On-board 4 green LEDs indicate battery charging and discharging levels of 25%, 50% , 75% and 100%
*On-board blue LED show the status of power on/off


<head>
'''Safe power management'''
*Equipped with momentary button for easy power control
:Press the button to turn on
:Press the button and hold for 1~2seconds to reboot
:Press the button and hold for 3~7seconds to implement safe shutdown
:Press the button and hold for >8seconds to force shutdown
*Supports safe shutdown and full poweroff through software
*On-board blue LED shows the status of power on, reboot and shutdown
*On-board pin header to select auto power-on when power supplied or battery installed
*Ultra-low standby power consumption of μA to maximize battery life
*Operate in both charge mode and boost mode to allow full system management and battery power management
*Advanced system power path management avoids frequent charging and extend battery life
*Advanced system power path management allows 3A fast charging and powering Raspberry Pi at the same time
*Powers the Raspberry Pi via the 40-pin header - no additional cabling required
*On-board DC power jack (5.5*2.5mm) and XH2.54 connector convenient for power input
*On-board PH2.0 connector allows to connect external power switch and DIY your perfect case
*On-board XH2.54 power output connectors allow to  power other devices
*Mounting holes and standoffs provide mechanical stability of the Raspberry Pi and X750 assembly
