I want to share how to run RST-135 mount with power bank(portable charger). A power bank supporting USB PD and a 15V decoy trigger cable can provide 15V to the mount. The RST-135 mount consumes 15V 0.2A for tracking, so it consumes 24Wh in 8 hours. For reference, the 10,000mAh power bank has a capacity of 37Wh. Power banks are a good solution because they are readily available and inexpensive.

What is the USB PD 
USB PD 15V decoy trigger cable (select – 5525 interface 15V)
