Little more complicated than that. The amperage is divided based on need, but the voltage falls to lowest common denominator. So let's say you have a phone and a MacBook. The phone supports only 5V and 9V, the Mac goes up to 20V. The cable will push 9V to both devices and share amperage. The phone takes 2 Amp (18W) and the Mac will take the remainder (3 Amp, 27W).It only shares 140W if both devices accept 28V.So you don't need "double" but it's easy to get throttled by voltage. Anker recommends at least a 45W adapter since that unlocks 15V usually and at 5/9V pushes a full 3Amp.

I assume you need an outlet charger than is "double" whatever charge rate you want?

You can't double power out of nothing.
It seems there's some confusion about how this cable works, if you're inputting 140W, you can't expect both devices to receive more than that combined.
I recommend reviewing the following concepts:
Law of Conservation of Energy
Electrical Power Law (P = IV)
These will help explain why energy can't be created or multiplied without an additional power source.
You didn't read my post clearly. I never said that you could. Encourage you to reread and review what I actually posted.

I just read it. If one device is drawing 140W (28V at 5A), then the power source is fully used. There's nothing left for a second device unless you reduce power to the first. If both devices are running, the combined draw will always be 140W, or less if both devices are drawing power at their max.
I pointed out a mistake in the physics. There's no shame in that. Everyone gets things wrong sometimes. But refusing to accept a clear correction is a problem.

It normally cycles between ~$18 and MSRP, so $16 is a decent price.
I like this cable because:
- I can use smaller, cheaper, 1-port USB-C AC adapters instead of larger, more expensive, 2-port USB-C adapters
- It reduces the cable weight and bulk by nearly half, since there's only the splitter and an extra foot of cable at the end
- It simplifies charging, since I don't have to deal with 2-port AC adapters and how they often split power very unevenly, forcing me to keep track of which cable is the higher power one
Make sure to look at the "Charging Guide" table to set your expectations on how your gadgets will charge so it meets your expectations, though.
