What is Reddit's opinion of 6 Pack MELIFE Type-C USB-C PD 12V DC Fixed Voltage Power Trigger Module 5A Type-C Female Input Module?

From 3.5 billion Reddit comments

Yes, these are much cheaper but you're limited from then on.

While this will work hypothetically (my laptop is a 93 wh and it charges at 60w) as soon as I connect it while I'm using it the power draw on it can be as high as 230w while I'm gaming. So you can charge it within pd spec but you can't use your laptop and charge it at the same time.

Now you can wait until eventually they release a pd spec that supports that wattage but we are relatively far from that (they exist and some new devices support this but it's still very new tech. You likely won't see it for another 3 4 years

If you do want to do this for other projects that have under 100w of power draw you can use these I personally used these to pull 12v out of my power banks. But please don't do this for your laptop. It won't work

The guy I bought my Z12 from said that he had never used the fan before, but the mirror obviously takes a while to get ready. Originally there was a barrel jack and while using a lead battery or making a special 12v lithium battery with a special connector just for the telescope would work, I figured they were both too inconvenient and i'd never use the fan either. So I made this USB-C power delivery connector and replaced the barrel jack. Now, any battery bank with power delivery capability will send 12V to the fan. Link for the chip is below:

The board isn’t doing that, your MacBook Pro has a controller that tells the charger brick to switch to 20V. Without a controller IC you can only get 5V, and possibly 0V since the small board is unlikely to have any pull down resistors on the CC lines.

These boards have the chip to negotiate the 12V; all you’d need to do is solder the + to your board’s + and GND to GND.

They are all a bit dodgy. If the power supply doesn’t support the requested voltage, these boards give you the next highest voltage. I also have no idea how much current they ask for, and there is no way for them to tell you how much current you’re allowed to draw.

So they are helpful for hackers but are not safe for any other applications. IMHO.

Need a chip to talk to the power bank to negotiate above 5V. There are modules like this.
