The cave thing was worse than you remember: he got in an argument on twitter with a guy telling him how dumb the submarine idea was, so the smart reply was to call the guy a sex tourist... and it was obviously the cave expert called in to supervise the entire rescue.
Nevermind how that was an ad hominem to begin with lol.
Not my case, fortunately. Yes, I've got the official dock. Yes, I've moved from 512 to 1tb microSD. Yes I've pushed the 64gb ssd to 256 and today 1tb, but that's it. No screen protectors, skins, case, controllers, power banks.
I'll admit that I don't like screen protectors and skins, already have a badass power bank and multiple gamepads lol... plus for a limited amount of things I've got a 3d printer, so that's another way around the issue.
Maybe long term, but other than that they're extremely similar. Same specs and while Samsung makes the flash memory I prefer, the Amazon Basics ones are made by the company that bought Lexar and makes the drive in the 64gb Deck.
Ender 3 with BL-TOUCH, that BTT drop in replacement board with silent steppers (the first model), geared extruder, Micro Swiss nozzle, Creality glass bed, unholy loud Sunon fan on the block and a few printed extras.
Then a Monoprice Mini Select v2 with an aluminum extruder. Both have their Raspberry with camera and Octoprint.
You shouldn't have to do any conversion, the whr value is what's used to allow or not powerbanks on airplanes so that value is either clearly in the specs, or if you already have it, on the bottom :)
I'm going to add that the math about the Deck having a 5200mah battery and thus with (let's say) a 25000mah powerbank it's easy to think that 25000/5200 almost 5 charges... that's wrong. The Deck has 7.7v battery while powerbanks normally are 3.6 so things don't translate directly.
Fastest way to know? https://www.steamdeck.com/en/tech/ The Deck has a 40Whr battery, a 20000mah powerbank should be around 74Whr and there the math is clear: less than two charges. Usually on the bottom of a powerbank there's the specs, should have that value too.
Sabrent is a well known company and, while I personally don't have experience with their stuff, LTT often uses their ssd for builds.
Right now I'm on one of those dodgy 256gb Kingdata... under the sticker it was all Micron number parts so at least the one I got is fine. But I'm looking forward prime day to see if I can get a tb of something more reputable XD
The Nintendo Pro controller needs a warning: triggers are not analog, they're normal buttons. On the Switch you don't notice its too much because no game uses them, but otherwise it's an important bit of information. Even something simple like Grand Theft Auto is going to be worse for it as soon as driving comes into the picture.
It's a rare intro that gets me to be less lazy and skip it... until the peppy remix. That felt so exceptionally bad (and often out of place! Hunted alien getting cornered and torched by flamethrowers? Yay cut to happy song!) that I would chuckle regularly. Sharknado levels of so bad it's good.
