This was for a work project that was originally designed for the cheap 12 and 5 volt lithium ion batteries, but because of space constraints it was decided to switch to USB Power Delivery and power everything from one battery pack. As such I needed a nice big chonky power bank, and when it comes to performance, reliability, and bang for the buck, it's hard to beat Anker. And since this thing is designed to charge laptops, I was confident it would give me at least a couple of hours through a decoy adapter. It's not like I'm using enough LEDs to light up an aircraft hangar.

This thing is capable of cranking out 20 volts at 3.25 amps, which is good enough to power my Thinkpad if I wanted to. But the most the buck converters in my project could tolerate was 16 volts or so, so I set the decoys to 15. That would let me run longer thinner wires if necessary without too much power loss.

This is about a half inch longer than the aforementioned 12 volt batteries, and even though Power Delivery can be a bit of a pain to deal with as a DIY maker, it was totally worth it here.

One gripe I do have is that the USB C port can drop to 5 volts if a device is plugged into the USB A port first. No problem, just connect the PD device first and Bob's your uncle. I could see myself using this to keep a laptop going, but a more portable device like a Nintendo Switch or a Steam Deck would be super awkward unless there's a table nearby. This is definitely too chonky for pants pockets.
