4 x 12V DC Power Outlets for your Equipment

A powerful MOSFET transistor provides the “electric juice” to your precious equipment. It supplies electricity to the 4 outputs, which you can individually switch on and off via software.

Built-In Voltmeter

A 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

The 8 Volt output is suitable to provide power to your DSLR or Mirror-less camera. We provide different battery couplers for Canon, Nikon, Sony and FUJI Cameras

More Than 10A of Total Power

The power controller has been designed to support up to 10 Amps of total current.

Standalone Operation

The Pocket Powerbox can work “out of the box” as a standalone device. Just plug the cables, set up 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 of providing 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)

The controller can auto-adjust the heater power levels 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 turn on and precise tune the level of your dew heaters.

ASCOM 6 Fully Supported

The 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 Observing Conditions)
  • Switch ON or OFF all 12V outputs. (ASCOM Switches)

INDI Fully supported

The Pocket Powerbox fully supports INDI - Bundle it with Stellarmate or any other device that can use INDILib.

LED Indicators for Power and Failure States

The LED will blink a code to warn you regarding important power issues (e.g over or under voltage). The already dimmed LED can be turned off using the software.

Power Cables are Included in the Package

Four power cable (DC 2.1mm to 2.1mm male - 1m) are 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.

USB 2 Connectivity

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

Reverse-Polarity Protection

The Pocket Powerbox has been designed with reverse-voltage polarity protection. It will definitely save your night if you accidentally connect the main power supply in reverse!


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 upgradable to support future features and bug fixes.
