Pegasus Astro Pocket Powerbox Power Pack

The Pegasus Astro Pocket Powerbox is suitable for the “grab and go” astrophotographer who doesn't need a lot of automation. The device can provide 10Amps of power, a sufficient number of 12V Outputs, Two Dew Heater Channels,  A DSLR power output, and an environmental sensor to monitor humidity and temperature.

4 x 12V DC Power outlets for your equipment

A powerful mosfet transistor provides “electric juice” to your precious equipment. It supplies of electricity 4 outputs. Can switch on/off for all ports.

Built-in Voltmeter

Precise voltmeter measures and displays in real-time your input voltage. If the input is more than 14V, the power is instantly cut off to protect your equipment.

Camera / DSLR Output

An 8Volt Output is suitable to provide power to your DSLR camera.

More than 10A of total power

Controller has been designed to support up to 10 Amps of total current.

Standalone Operation

Pocket Powerbox 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 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)

Firmware can auto adjust the PWM Outputs by consulting the environmental sensor Dew Point reading. Just click “Auto” and leave it to the Pocket Powerbox to decide if it is time to switch on and precise tune your dew heaters.

ASCOM 6 Fully supported

Pocket powerbox fully supports ASCOM6. In combination with our main program which acts as a server, you can use our latest ASCOM 6.3 supplied drivers to:

  • Pass environmental settings to supported software (e.g Sequence Generator Pro / MaximDL )  (ASCOM ObservingConditions)
  • Switch ON or OFF all 12V outputs. (ASCOM Switches)

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. The LED is very dim but in case you don’t like it on you can switch it off via the software.

Power Cables are included in the package

Four power cable of DC 2.1 mm to 2.1 mm male (1 m) is included in the package.

External Environmental Sensor

External one (1) meter temperature & relative humidity sensor is included in the package. Know exactly the environment conditions of your location.  Temperature, humidity and dew point measurements are displayed in the software.

USB2 Connectivity

Connect the device to your laptop/PC and control Pocket Powerbox from the supplied software or ASCOM drivers

Reverse Polarity Protection

Pocket Powerbox has been designed 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 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

The device is firmware upgradeable to support future features and bug fixes.

Compact Size and Lightweight

A hard plastic ABS lightweight and compact sized box encloses the controller board. Size is 109 mm x 74 mm x 25 mm. The weight is 250 grams.

Excellent device for astro imaging setups

This little device decreased my setup and break down time in more then a half, helped me with wire management and weight balance. I own two of these, one permanently mounted on an OTA of Meade LX90 and the other one on a Meade C6000 70mm APO refractor on an AVX mount. Especially for the people who own telescopes like LX90 and using Alt/Az mounts on a wedge for astro imaging would know very well how hard it is to keep the wires from wrapping around the tripod. This box along with a single board PC mounted on the OTA allowed me to have just a single power cord running down off of my setup and contain the rest of the cords for the imaging camera cooler, guiding camera, due heaters, mount power and single board PC power cord. Now I don’t have to spend an hour plugging and organizing the cords. With the smaller refractor it is also very beneficial making it super easy building a portable scope with all the wires mounted on the OTA for easy field setup. Environmental sensor is a nice bonus, works well. I especially recommend it to everyone like me who doesn’t have a luxury of a permanently mounted scope. Even if you do, you would probably still enjoy it.
