  • Pegasus Astro Pocket Powerbox Advance (Gen3)

    The Pegasus Astro Pocket Powerbox Advance (Gen3) consolidates your entire imaging rig's power and data management into a single 350-gram unit. It delivers a total of 14 Amps through four switchable 6A 12V outputs, two 5A PWM dew heater channels, and an adjustable 3-19V output for powering DSLRs or mini-PCs. The integrated USB hub features four USB3 and two USB2 ports, each delivering 3A with full surge and ESD protection, while the 1.5A motor controller automates your focusing routine.

    14 Amps of Total Power Across 4 x 12V and 1 Adjustable Output

    Designed to run a complete portable setup, the Pocket Powerbox Advance Gen3 accepts an unregulated 12V DC input and distributes up to 14 Amps of current. It features four individually software-switchable 12V DC outputs, each capable of handling a 6A load for powering your mount, camera cooler, and other accessories. A dedicated adjustable output provides a regulated 3-19V at up to 3 Amps, ideal for powering a specific camera model via a battery coupler or running a NUC-style computer at the telescope.

    A 6-Port Hub with 4x USB3 and 2x USB2 Ports

    Cable management is simplified with an onboard 6-port USB hub that connects to your host PC via a single USB3 Type B cable. The hub includes four high-speed USB3 Type-A ports for cameras and filter wheels, alongside two USB2 Type-C ports for mounts or focus controllers. Each port is rated for 3A, can be individually enabled or disabled via software, and is fully protected against electrostatic discharge and power surges, ensuring reliable communication with all your devices.

    1.5A Motor Controller and 2-Channel 5A PWM Dew Outputs

    The Powerbox Advance Gen3 integrates two key controllers to automate your imaging session. A built-in bipolar stepper motor controller can drive most electronic focusers on the market, delivering up to 1.5A per coil for precise, repeatable focus adjustments. Additionally, two software-controlled PWM outputs provide up to 5A of current each for running dew heater straps, with automated duty cycle adjustment based on the readings from the included environmental sensor.

    Onboard Voltmeter and External Sensor with ±0.5°C Accuracy

    Real-time monitoring keeps your system running safely through the night. An onboard voltmeter measures and logs the input voltage, alerting you to potential power supply issues before they affect your session. The included external sensor provides ambient temperature readings with ±0.5°C accuracy and relative humidity from 0-100% with ±2-5% accuracy. This data is used by the software to automatically manage dew heater output, preventing moisture formation on your optics without wasting power.

  • What is the total power output of the Pocket Powerbox Advance Gen3?

    The Pocket Powerbox Advance Gen3 can deliver a total of 14 Amps (or 168 Watts) across all its outputs. Each output has its own maximum (6A for each of the four 12V outputs, 5A for each PWM dew heater channel, 3A for the adjustable 3-19V output), but the combined draw of all outputs must stay within the 14 Amp total.

    Can the Pocket Powerbox Advance Gen3 power my DSLR or Mirrorless camera?

    Yes. The adjustable 3-19V DC output is specifically designed for this purpose. You can set the voltage to match your camera's requirements and use a compatible battery coupler (sold separately) to power it directly from the Powerbox, eliminating the need for camera batteries.

    How many USB devices can I connect to the Pocket Powerbox Advance Gen3?

    You can connect up to six USB devices. The built-in hub provides four USB3 Type-A ports and two USB2 Type-C ports. All six ports connect back to your computer through a single USB3 Type B cable, greatly simplifying your cable routing.

    Does the Pocket Powerbox Advance Gen3 work with my specific electronic focuser?

    The integrated motor controller supports any bipolar stepper motor that requires up to 1.5A per coil. This covers a wide range of popular focusers. The controller is fully supported by Pegasus Astro's Unity Platform software and has ASCOM 7 and Alpaca drivers for compatibility with third-party imaging software.

    How does the Pocket Powerbox Advance Gen3 prevent dew on my 8" SCT?

    The included environmental sensor constantly measures the ambient temperature and humidity. Using this data, the Powerbox's software calculates the dew point and automatically adjusts the power level of its two 5A PWM outputs. By connecting dew straps to these outputs, the system will gently warm your telescope's optics, keeping them just above the dew point to prevent condensation all night long.

    What happens if I plug in a power supply with reversed polarity to the Pocket Powerbox Advance Gen3?

    The Pocket Powerbox Advance Gen3 has built-in reverse polarity protection. If you accidentally connect a power supply with the wrong polarity, the unit will not power on and will not be damaged, protecting both the Powerbox and all connected equipment.
