Sofia ★★★★★

Tapped the 6-24V input range for a small solar setup and it holds a steady 5V even when the sun dips. The synchronous rectification keeps it cool enough to touch after an hour of charging. Exactly what I needed for the price.

Joshua ★★★★★

Wired this into my car’s 12V line to charge my phone on long drives, and it’s been rock solid for two months. The synchronous rectification keeps it cool even when I’m pulling 2 amps, and the 6-24V range means I can test it on my drill battery too.

Christopher ★★★★★

Spliced this into an old GPS tracker that needed 5V from a 12V battery bank, and the synchronous rectification keeps it cool enough to touch even after hours of run time. Input range handles voltage dips without hiccups, which is more than I can say for the last module I tried.
