I've been looking for a product like this. Most USB C PD to DC modules work in the opposite direction, USB C to DC output.This does exactly what I need, converts 13.7 LiFePO4 input to a negotiated USB C output.I tested it with:Raspberry Pi 4b, successful at 5.1vMicrosoft Surface Go Laptop 2, successful at 12vAnker USB C in/out travel battery power bank, successful at 12vShame they sanded the chip identifier off the actual converter IC chip, I'm curious what they used for it. But overall, it works perfect, there aren't a lot of modules out there that can convert DC to USB C PD.

These modules do what they say on the tin, but be aware that they cannot boost voltage. Even though they're listed as accepting 8-32V (although 8-30V is printed on the board itself), your input voltage needs to be slightly higher than your desired output voltage. For 20V operation, I found output would sag unless I fed at least 21.5V in.Unfortunately, their advertised PD voltages to match input very well. If you feed in 8V, it will still tell your device it can deliver 9 or 12V. If your device requests 9/12V, it will instead receive just under 8V. At the very least, it only advertises voltages above 12V if input is at 19V or higher. Realistically, you want at least 22V going in.The outputs advertised do not change with input voltage while the module is in operation. It must be power cycled to switch from low-power (36W, only up to 12V, when input is below 19V) to high power (65W, up to 20V, when input is above 19V) operation.This unit can become quite hot if used at 65W at ~24V input for extended periods, enough that touching it instantly hurts. The inductor and small microchip are what produce most of the heat.I selected the 5.5x2.1mm (5521) version, and it indeed fits a 5.5x2.1mm barrel connector just fine. The section with a barrel jack can be cut off, if desired.If you're aware of the limitations on this unit, it works pretty well. It's also quite inexpensive. Just pay attention to how much voltage you're feeding in.Listing of supported fast charging protocols:High-power mode, when input is at 19V or above:USB PD (65W) - 5V, 9V, 12V, 15V 3A - 20V 3.25A - 3.3-16V 3.25A (PPS) - 3.3-21V 3A (PPS)Qualcomm Quick Charge: - 5V, 9V, 12V, 20V - 3.6-20VLow-power mode, when input is below 19V:USB PD (36W) - 5V, 9V, 12V 3A - 3.3-12V 3.25A (PPS) - 3.3-12V 3A (PPS)Qualcomm Quick Charge: - 5V, 9V, 12V - 3.6-12V

I really like the new Echo Hub and have three ready to install where our old 12v security wires exist like I did with Ring keypads. However, I was having trouble finding the proper 12v stepdown adapter until I found the AITRIP charging modules and made my own. It appears that the Echo Hub requires more than standard PD 5-volt and 9-volt despite what Amazon's website states. Only adapters that support the optional PPS standard, introduced with PD3.0 to automatically adjust to specific voltages, have worked for me. I believe that this is because the exact spec is actually 5.2-volt/2.4-amp (12.5-watts) as stated on the Hub adapter and not an even 5 volts. I couldn't be more pleased with the AITRIP modules. They run cool at the 12.5 watts needed for the Echo Hub and allowed me to make three adapters that cost less than $6 each! This is way less expensive than buying PoE injectors and PoE to PD3.0 PPS converters like Amazon would have us do for a clean in-wall installation.

I purchased this to use with the power supply for an "18v" power tool battery charger I have.Since the power supply is 21v it is perfect for this charger module, and I was able to charger my laptop using the 20v PD profile.

VERDICTRecommendedWHYDC 5521 to USB-C PD 65W output. Good for charging cellphones, MacBook Air, ThinkPad - using DC input like from a car, solar system with battery pack. Nice compact design and works well so far.
