Hi everyone, this is my first post! Long time MikroTik fan.
MikroTik devices are really modular when it comes to power so I've been looking into a portable solution for fun.
The keyword here is "portable", it has to be easily transported, not involve solar power and not require dragging around a 12V car battery.
The devices I'm testing this with are an LtAP LTE6 and a hAP ac.
I've seen this done
with a different TalentCell power pack that outputs 12V DC, powering a hAP ac² and a homebrew USB power-hub.
My thoughts for a setup involve using a TalentCell PB240A1
and a barrel plug to a two port barrel plug connection to the devices (like the twitter post).
Since I stack the connections to the DC output via a single port and the devices connect to it in parallel, the amperage draw from the battery increases, not the voltage.
If my math is correct, there should be more than enough power for both devices [the battery specs state the output at (29.4V-21V) / 3A].
What I'm looking for from the community is any advice on additional safety measures, fuses, or even a tried and tested setup direct to a battery without any middle-ware.
A better setup to me looks like a direct connection to a battery, with just a fuse. No circuitry or step-up/down converter in between except for maybe an undervoltage/overvoltage protection circuit.
I could also add a current measuring device inline to the cable and set alarm triggers when it hits about 80% use. A direct connection would offer way better efficiency in all cases.
I'm aware of the PowerBox and PowerBox Pro but it seems slightly unnecessary for a portable setup. A more expensive option would have been with a GoalZero battery.
However, GoalZero made the Sherpa 100AC without a 12V output compared to the older versions. It does have a built in inverter (modified sine wave) but again... efficiency!
Anyone who has tried this before, I would love to hear about your setup!
