What's REALLY amusing to me is that you can order an entire Surfrider clone for $20 and yank the 20X1 adapter out of it and save money on all these "legit" 20x1 adapters. https://www.fasttech.com/p/1849003 Oh, the switch is also 20x1 and works with Caravela tubes. Bonus! I did just that, I'm currently using that 20x1 hybrid adapter and switch with a Caravela 18650 tube.There are multiple big name websites out there that sell 20 x 1.0 hybrid adapters.
Edit: for $22 you can get a copper 20x1 adapter with the XXIX clone - https://www.fasttech.com/products/0/10009268/1832004 which also has a 20x1 switch.
