2PCS HiLetgo DC-DC Power Buck Module 6V-32V12V24V to QC3.0 Fast Charging Single USB Charging Converter Board Review

I used one for fast charging in the car console and the other as a buck converter. Fast charging works great, no problems with it.

Fast charging my Galaxy S21+. no problem. Stays cool as a cucumber and does exactly what I need it to do. The pay is small but good. As long as it lasts, this thing is a solid winner for my needs.

I installed it in my homemade airplane as a USB power port. I've found the QC3 function to work fine, but introduces a lot of electrical noise on the 12V rail. My intercom picks up the noise when it starts charging, so unfortunately I can't use it on my plane.

Connected to VW Sportwagon 2013 via original 5A fuse in the main fuse block near the door. Looks very factory and they are working great so far. I use them to fast charge my Samsung S20 and iPad. Allows me to connect a factory iPod USB port through the head unit.

I like this buck converter, I used it in the car. My LG phone identified it as a fast charger. My other phone didn't do this and it could be a cable/phone issue. (Actually I didn't care that the phone still charged fast!) I will buy more for 5 volt power adapters in the future.

I am EE and I own many of these types of modules. To date I have not written any reviews. This is the best. These modules performed very well in everything I offered them. I use them on my Sunkingdom 18W solar panels and also directly for a great USB fast charging system that tolerates solar outages. quality inductance!
