Product Description

This small but powerful device (in short PPBADV) is a welcome addition to our Powerbox product series. Proudly stands between Pocket Micro and Ultimate Powerbox v2. It has been designed to provide more advanced features than Pocket Powerbox Micro and especially a USB Hub that accepts up to 4 USB ports.


4x 12V DC Power Outlets

A powerful mosfet transistor provides "electric juice" to your precious equipment. It supply of electricity 4 outputs. Can switch on/off all 12V outputs (not individually).

This single channel can provide up to 10Amps of current to all ports. Current is shared among the 4 x 12V ports

Built in Voltmeter

A precise voltmeter measures and displays in real time your input voltage. If the input is more than 14.5V, the power is instantly cut off to protect your equipment.

Adjustable Regulated Output

An adjustable output is suitable to provide power to your DSLR / Mirrorless camera / or your RPI3/4. You can tune the voltage to different levels (3,5,8,9,12 Volts). Please note that we provide a wide range of battery couplers for Canon, Nikon, Sony, FUJI Cameras

Built in Amp-Meter

An Amp-meter placed after the DC input reports the total electric current. There are also three additional amp-meters: One for the 12V outputs and two for the Dew Heater Channels. This allows you to easily monitor the detailed and overall power consumption of your equipment.

Expansion Port (EXT)

Expansion Port (EXT)

EXT (expansion) port is available for device expansion. This RJ12 socket allows the connectivity of current and future Pegasus Astro products. Plugged devices can be controlled from Pocket Powerbox Advance standalone software or dedicated ASCOM driver.

More than 12A of total electric current: The powerbox has been designed to output up to 12 Amps of electric current. Please note that a usual backyard astrophotographic setup requires 5-7 Amps.

Embedded USB3 Hub – 2 x USB3 & 2 x USB2 Ports

A powered USB3 Hub at the back of the device provides:

  • 2 x USB3 SuperSpeed Ports
  • 2 x USB2 High-Speed Ports.

The new SuperSpeed hubs operate in parallel with the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.

Embedded USB3 Hub

USB Port Configuration under PPBADV Gen2

  • USB Port1 supports USB2 devices
  • USB Port2 supports USB2 devices
  • USB Port3 supports USB2 & USB3 devices
  • USB Port4 supports USB2 & USB3 devices

* Older product revision (Gen1) had only 3 out of 4 USB Ports that were compatible to USB2 devices. For detailed information please check the product manual.

USB High Power Output

USB Port 1 provides up to 3Amps of current. You can connect any device that requires 5V. E.g a Raspberry PI 3/4 or Intel Compute Stick M3/M5 can receive power from this specific port.

Other Key Features

  • Standalone Operation "Out Of the Box" - Pocket Powerbox Micro can work "out of the box" as a standalone device. Just plug the cables, setup the "autodew" functionality and every time you boot the device, it will retrieve your settings. So, If you don’t like to connect to a PC every time, you don’t have to. Simple as that!
  • Two Channel Duty Cycle PWM Outputs - Two Pulse width modulation (PWM) outlets are capable to provide power to your "thirsty" Dew Heaters. No more moisture fuzzing your equipment and destroying your clear nights. These outlets can be remote-controlled from your laptop using the supplied software.
  • Auto Adjustment of PWM (Dew Outputs) - Controller can auto adjust the heater power levels by consulting the environmental sensor Dew Point reading. Just click "Auto" and leave to Pocket Powerbox Micro to decide if it is time to turn on and precise tune the level of your dew heaters.
  • More than 10A of Total Power - Controller has been designed to support up to 10 Amps of total current.
  • Led Indications for Power and Failure States - Led can blink in patterns to warn you regarding important power issues (e.g over or under voltage). Moreover light can be turned off using the software. Our led is very dim but in case you don’t like it on you can switch it off via the software.
  • Reverse Polarity Protection - Pocket Powerbox Micro has been design with a reverse voltage polarity protection. It will definitely save your night if you accidentally connect the main power supply in reverse polarity!
  • A Hardware Watchdog - A hardware watchdog resets the device if for any reason there is no response from the controller for two seconds. A neat feature in the unlikely event of a controller freeze – when you have a remote observatory and you need to be certain that everything works as expected.
  • Upgradable Firmware - Device is firmware upgradable to support future features and bug fixes.
  • Compact Aluminium Enclosure - A high-quality robust, blue anodized aluminum enclosure houses the electronics of the Pocket Powerbox Advance. Size is 100mm x 71mm x 24mm. Weights 250 grams.

Supported By:

ASCOM 6 Fully Supported

Pocket Powerbox Advance fully supports ASCOM6. In combination with our main program which acts as a server you can use our latest ASCOM 6.5 supplied drivers to:

Customer Reviews

Based on 4 reviews
Great tool for my astrophotography project

I'm connecting the Powerbox to my Raspberry Pi 4B

Pegasus Pocket Power Box Advance Gen2

This is my second Pocket Power Box Advance, and it is an excellent product. It is capable of distributing enough power to run a mount, camera and anti-dew strips. I like the Pegasus Unity interface, which provides control over the power distribution, dew control in addition to monitoring of environmental conditions through an external sensor. It has a sufficient number of USB ports (4,) for camera, guide camera, and focuser. Delivery from All-Star Telescopes was prompt!

Great dew controller

Great for keeping the frost off while imaging in winter.

PowerBox Adv Gen2

Lightweight, more than enough connections including USB3 for main camera and 12v (or even adjustable voltage) for dewheater strip(s). This mid-line model suited me best for the number of connections I needed. Used velcro to attach to scope. Interface for box operation is straightforward (i'm using a laptop remote connection). Have yet to test the temperature sensor "auto" setting for the dew heater, been manually setting for now. Use some zip ties or other straps to keep the cable management in check for no snags.
