My plan is to get around this temporary slowdown is with modular 4S~2P battery packs that you remove and charge at 100W. With 5 of them in a Onewheel thatâs 500W charging at most via USB C. While you were at it you could also include the booster for a single input to charge the whole board at once.
While this setup would cost lots more than a standard pack if you factor in you get five PD powerbanks for when you arenât riding the cost might seem better.
Hmm wait what? I forgot to post this module here.
Sadly he doesnât bother demonstrating proper cell group isolation. 
Eh if people can get away with that in PEVs I think its fine in a battery bank.
Side note, that board does not let you actually pull 100w. Voltage drops off really hard when you get close to 5 amps. Itâs closer to 90w as specified in the video.
Playing The devilâs advocate I think power banks are way more likely to be extremely close to you/something fragile or brought somewhere like on a plane. I think itâs just a failure any time you demonstrate a battery build to beginners without mentioning cell isolation.
ok how the hell did I not post this one hereâŚ
while on the topic. Identical looking ones claim 120W.

Since there are no 120W trigger modules, I assume that is really just for charging itself and other devices that support 6A. If you took two of them and plugged them into each other what would happen? whichever one has lower voltage on the 4S input receives current?

@Battery_Mooch can you wrap your head around what they mean with the parallel and series connections??
Parallel current sharing just means you can connect two of them, so instead of a 20V 5A supply you can gang two up for 20V 10A. Similarly you could get 40V 5A total. Each supply unit has an STM32, as does the LCD control module, and they communicate wirelessly.
Aside from acting as a coordinator for multiple units, the main advantage is thlat you can have a precise and fairly clean supply for testing and lab work while being completely isolated from mains. Normally youâd have to pick a mains powered lab supply that is to some extent referenced to earth unless you go a bit crazy with it, or you run a battery supply. Your options would be usually a USB power bank (very very noisy and loose tolerances around a standardish 5V), directly off a lipo (much less noisy but no voltage regulation) or building your own regulator to run on battery power (probably noisy, definitely difficult and expensive). This solution is still expensive compared to a similar power output mains supply, but wide input clean output and isolation are the selling points
This is some cool shit
Have you looked into USBC trigger boards? This just looks like one with a barrel jack.
I got that much, its whatever the hell its doing to get USB C 3.1 features⌠28V is sort of mentioned but also no listed in its specs/abilities.

Ok this listing actually make sense. I think I will get this one.

Yes, but theyre probably enamel coated and do have some form of insulation between them. A little dab of silicone never hurt nobody though.
Thx, naked wires spoke the hell out of me.
