Built for advanced users and enthusiasts, it features refined hardware, a transparent shell, integrated speaker, and a high-capacity 2500 mAh lithium battery.

Key improvements and features include:

  • Single power on/off switch that fully cuts power when the device is off, eliminating phantom battery drain and preserving battery life.
  • Advanced battery management IC with real-time monitoring of battery percentage, voltage, current draw, and charging status.
  • Matte display for improved outdoor visibility and reduced glare in direct sunlight.
  • Flat 360-degree knob button inspired by the classic click-wheel design, offering precise and intuitive navigation.
  • Dedicated GPIO port enabling future user-developed add-ons and hardware expansions.
  • Improved charging performance for faster and more efficient recharging.
  • Built-in microphone with hardware toggle, allowing quick switching between the internal microphone and external audio devices.
  • Automatic audio switching that seamlessly changes from speaker output to headphones when plugged in.

This product includes only the Portapack H4M unit with transparent shell, integrated speaker, and 2500 mAh lithium battery. It does not include a HackRF board.

I have an old version. Pre v6, clone from 2014. Would that fit? https://imgur.com/a/E7Vo932 Kind regards, Pepijn

Hello, Thank you for your question. Based on the photo, that appears to be a very early pre-v6 HackRF clone from around 2014. For boards of that type, compatibility with the Portapack H4M is unfortunately not something we can guarantee. The main issue is that older clones often differ from the later standard HackRF One layout in terms of header alignment, PCB dimensions, and overall mechanical fit. Because of that, the transparent shell especially may not fit correctly even if the board looks similar. So in this case, we would not recommend assuming it will fit. The H4M and shell are best suited for the later standard HackRF One layout / newer compatible boards. Kind regards.

Advantages
Great addition for the HackRF One.
It gives many options, tools etc, without having a computer at hand.
Had a little bit problems with my Portapack but SDRSTORE solved it perfectily.
They're very busy, so be patient for there answers.
For the rest, I'm very happy with it :-)
Disadvantages
Only thing what is, for me, a minor is the dialwheel, it feels a bit "flimsy", and personaly I would prefer a dial knop instead of a wheel.
