Use a USB-C PD power bank, and a USB-C power sink, and you can power the KX2 handily. I can power my KX3 that way, and most of my other QRP rigs as well. The sink I use is the PD Buddy Sink found on Tindie. It handshakes with the PD power bank and provides 12v at 2-3A (depending on the bank). I have a RAVPower bank with roughly 27Ah (probably rated at 5v, but that's ok) that works fine with this. It'll also take input power from a mains power supply used to fast-charge such a bank, or that might be used to power a Chromebook or other laptop. That gives me a VERY small and packable mains and mains-free power solution for all of my radios. I could even set it for 9v for the radios that use THAT.
There are other brands of power sinks out there. I ordered two of these: https://www.amazon.com/gp/product/B07T2858G6/ but they haven't arrived yet, so I haven't tested them. The Buddy Sink is programmed by connecting it to a computer via USB-C, then accessed with a terminal program. The ones I haven't received yet have a preset group of output power profiles you can toggle through by pressing a button on the board. There are others as well, but I haven't tried any others yet either. This isn't a massively unique approach. I'm sure there are other, cheaper, and probably more specific power solutions, but this has the benefit of being a multi-tasker. With it, I can charge my Chromebook, my phone, my external speaker, AND run my radios. I can charge the bank with a power supply that weighs ounces and fits in the palm of my hand rather than a brick the size and weight of, well, a BRICK. I even found 3d printable cases for the PD Buddy Sink that will accomodate either a direct wire output or a PowerPole connector, so I can attach interchangeable power cables. 73, Gwen, NG3P On Mon, Dec 9, 2019 at 12:33 PM Ignacy <n...@arrl.net> wrote: > This is a QRP radio that likes traveling.
