The Dorhea MT3608 is a small adjustable step-up (boost) DC-DC module that takes roughly 2-24V in and boosts to about 5-28V. It can work well for light, DIY projects, but buyer experience suggests setup and expectations matter, especially for low input headroom and heat at higher current.
This IP68-rated DC step-down converter takes a wide range of 16V to 58V inputs and outputs a fixed 12V DC supply (up to 10A, 120W max). It is an easy way to run 12V devices from golf cart batteries or power-tool battery packs, with built-in protections for common electrical faults.
