The PD trigger is just a small board to tell the PD charger to give 20v to the usbC and then give it to your laptop so you still need to use the inverter and another PD charger. If you want direct 12v to 20v you should use a DC boost converter. You can adjust the output current and voltage.
Dc boost converter looks something like this: https://www.amazon.com/DROK-Transformer-Adjustable-Controller-Stabilizer/dp/B00C498MGY/ref=mp_s_a_1_8?crid=1SQU9SX8NW1TK&keywords=dc+boost+converter&qid=1676853448&sprefix=dc+boost+%2Caps%2C423&sr=8-8
I'm back with more questions. I have a small indoor garden in my living room which current has a few cfl lights that are doing a poor job of providing enough light so I think I'd like to upgrade the lighting with 2 100 watt (run @ 50%), cool white leds. I want to use cool white as this is for a simple indoor vegetable/greens garden - no concern with flowering. Can you look over my list of components I think I might use?
So far I have a laptop power adapter with a rated output of 18.5 V @ 6.5 amps (120 W) I was hoping if I don’t run the lights at more than 50% this should be acceptable…but I also don’t know if it would be safe or a good idea to run both emitters off 1 power supply of this rating … or would I be better off with something like : http://www.ebay.com/itm/16-7A-200Watt-Switching-Power-Supply-Driver-for-LED-Strip-Light-Display-86-265V-/281165945573 ? Price is a bit of a concern, but so is safety and space - I would like to avoid having a million different things in the area where I have my “garden”..
For emitters I have been looking at items on ebay such as: http://www.ebay.com/itm/100W-High-Power-Super-Bright-LED-Cool-White-100-Watt-LED-Lamp-Bulb-Chip-C-/350973550137 and http://www.ebay.com/itm/100W-High-Power-Super-Bright-LED-Cool-White-100-Watt-LED-Lamp-Bulb-Chip-CC-/390744099114… would you recommend any seller? I’ve read numerous places that many of the Leds on ebay are “counterfeit” or less than top notch quality - which is fine.. can you recommend any that are better than others?
Then as for proper voltage.. I’ve been reading lots about boost and buck converters, voltage rectification etc. (as well as power supplies) - I’ve been wondering if it would make more sense to invest in 1 power supply, and 1 boost converter capable of handling the entire load, or if I should have a boost converter for each emitter? Obviously running 1 at max capacity wouldn’t be efficient but one with like this: http://www.amazon.com/DROK-10-60V-Converter-Voltage-Regulator/dp/B00C498MGY/ref=sr_1_8 should be more than enough for 2 emitters. Or would it be better to use 2 power supplies, and 2 converters? My gut would say 1 power supply, 1 converter but I’d like to hear from someone else..
