Could these be filled from a Soadastream type CO2 cylinder?

I have the Sodastream system and it looks like you could make it work with a suitable adapter. I'm not sure why you would want to do it though. The Sodastream cylinder is too bulky to carry on a bike. It certainly would fill a lot of tires if you used it at home!

The Sodastream cylinder could probably also be used for forward thrust!
I meant filing the disposable CO2 cylinders from a Sodastream cylinder. Are they threaded?

The Sodastream cylinder looks like this:
Some of the 16g Co2 inflator cartridges are threaded depending on the inflator type:

A an adaptor could be made but there is no valve. Once the seal is punctured on the 16g cartridge, there is no way to reseal it.
I suppose some amateur machinist could make up something but the cost savings would be minimal. The Sodasteram cylinder costs $35 (refills are half that) . The 16g inflator cartridges only cost about $2.50 each and you don't use many. I bought a box of 6, five years ago and I still have 2 left.

I bought one of these from Luna Cycles. I didn't know they were on BangGood for half the price, but that makes sense. $10 for that sweet LUNA logo isn't so bad though...
I have the Milwaukee M12 inflator, that is a dream to use, compared to a good floor pump. I was just going to haul that thing around until I saw the "ePump" from Luna. Seems like a good idea, and much smaller/lighter than the Milwaukee M12 inflator, and can be powered from my bike's 52V pack.
I should probably pick up an AirZzoundz horn while I'm at it, now that I've got effortless air on tap.

I'd like to see e-bike manufacturers get together and agree on a standard high current power outlet with 12V converter to install on bikes. There are already quite a few portable electrical products that could be used with e-bikes. More are sure to follow. The USB port available on some bikes is woefully inadequate for most of these products. The only other option, without hacking into the wiring harness, is to remove the battery from the bike to access the contacts directly.

I ordered the best one I could find, so I could run 12V stuff from my 52V pack. I ordered this Pro Chaser 35A converter from Amazon: https://www.amazon.com/gp/product/B07GNV4WGT
Then, I ordered this fancy dash to go with it, for 2.1A USB ports and cigarette outlet: https://www.amazon.com/gp/product/B074FH81GQ
Also grabbed a GoPower 300W inverter, a 50A MAXI-Fuse holder, and a 12V fuse box, hoping to have a workable 12V system to play with, without adding any more batteries to my main pack.
