I just received the new Sandberg All-in1 Laptop Powerbank 24000. I have 3 Elektron devices that require 12V at 1 or 2A and it should be possible to power all 3 at the same time (potentially even up to 5!). There’s a 2.1mm DC out port that support 12V at 4A, so with a DC splitter and 2.5mm adapter you can power two Elektron devices. The two USB-C ports support PD at 12V/3A each. And the USB-A supports 5V at 4.5A.
It also has power through ability, so if you plug it in, it will provide ~45W to the power bank and assuming your devices connected use less, keep the power bank topped up, so it can serve as an 2, 3 or even 4-in-1 power supply for your devices as well (you do loose either the DC or one USB-C port when in power-through mode).
So you should be able to use up to 5 12V outputs at the same time - if you get a DC splitter cable, a pair of Birdcord PD USB-C -> 12V adapters and one USB-A to 12V converter (Birdcord or Ripkord) you’re looking at a total of 5 Elektron devices!
All this is theory, as I’m not sure if it can distribute enough amps at the same time on all ports and if the power through works as well as I hope, but I’ll be testing with my OT, ST and DNK once I get the DC splitter cable I ordered and report back here if anyone’s interested.
