4 x 12v DC Outputs

A powerful MOSFET transistor provides “electric juice” to your precious equipment via four 12V power outputs. The outputs can be switched on/off (all outputs, not individually).

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

Built In Sensors

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.

A temperature and relative humidity sensor measures and report your current environment values.

2X Dew Heater Outputs

Two dew heater outputs allow you to control your heaters precisely. Auto-dew functionality can automatically control the intensity of the heaters by consulting the built-in temperature and humidity sensor. A Pair of cable adapters from DC 2.1 -> RCA is included in the package.

Built-in Voltage and Amp-Meter

An Amp-meter placed after the DC input reports the total electric current and voltage levels. This lets you easily monitor your equipment’s detailed and overall power consumption.

More than 10a of electric current

The powerbox has been designed to output up to 10 Amps of electric current. Please note that a typical backyard astrophotography setup requires 5-7 Amps.

Embedded USB3 Hub - 2x USB3 and 2x USB2 Ports

USB High Power Output

USB Port 1 provides up to 3 Amps 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.

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

  • 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.

USB Port Configuration under PPBADV Gen2

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

Optional Pucks for other mounts

The Powerbox Saddle can be directly placed onto the NYX-101 mount. For another type of mount, an extra puck is required. Currently, the following mounts are supported:

Puck (PEG-PUCK-AM5) can attach the Powerbox Saddle onto the ZWO-AM5 mount.

Puck (PEG-PUCK-EQ6R) can attach the Powerbox Saddle onto Skywatcher NEQ6 and EQ6-R mounts.

Puck (PEG-PUCK-RST) can attach the Powerbox Saddle onto RST 135 and RST 300 mounts.

Stand Alone Operation Out of the Box

Pocket Powerbox can work “out of the box” as a standalone device. Just plug the cables, and 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 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 can power 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 to Pocket Powerbox Micro to decide if it is time to turn on and precisely tune the level of your dew heaters.

More than 10a of Total Power

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

LED Indications for Power and Failure States

Led can blink 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 if you don’t like it, you can switch it off via the software.

Reverse Polarity Protection
Pocket Powerbox Micro has been designed with reverse voltage polarity protection. If you accidentally connect the main power supply in reverse polarity, it will save your night!


A hardware watchdog resets the device if, for any reason, there is no response from the controller for two seconds. This a neat feature in the unlikely event of a controller freeze in a remote observatory, where you must be confident that everything works as expected.

Upgradable Firmware

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

Losmandy and Vixen style support
