On the X-09 lock, it is indeed charged by the dial. Turning it to the left.
The 2 pins on the back are shorted to change the combination.
The sliding rod is a tamer indicator. This is important because the serial number, which is located on the capacitor (sticker removed on yours), can be used instead of the correct combination to do a code change.
On many safes the lock is much more expensive than a door blank. So you would cut the door out, short the change key pins, and set a new combo with the serial number. Hopefully you documented this serial number in another safe. If you observe the tamper pin has been disturbed you know the security of the serial number has been compromised.

I recently retired an identical Mi Power Bank Pro as it was puffing up too, was still working but didn't want to risk it. Was purchased pretty much when it was launched so got quite a few years from it as a dash cam battery through hot summers as it has pass through charging.

Dave, please, stop pretending you’re unable to understand protections again a new, potentially dangerous disease. There’s no way you’re dumb enough to not understand the threat it potentially posed.

Right, you lost me. Lockdowns work (waves from WA) and save lives.

When it comes to breadboard power adapter – you just have to turn the breadboard around to get the correct polarity. 🙂

The Kaba Lock is used in Datacentres on Server Rack Cages. A company I have worked for had them on their cages in the IBM Datscentre at Norwest (just up the road from you, Dave). You spin them for up to 20 seconds or so to "charge them" and then use it like an old fanshion tumbler lock. You have to be reasonably quick or the charge would run out.

That's totally an underwater mine! AMAZING! 🤩🤯💥

I've smashed like on this video because of extremely accurate Dilbert comic. And the usual quality content. Thanks!

Other comments have already indicated what your bomb is. The enclosure is explosion proof, used in hazardous atmospheres where the flash point is low due to the presence of flammable gas or dust. I used to design instrumentation used in the oil and gas industries which used similar enclosures and intrinsically safe electronics.
