00:00Need solid DC-DC power converter for 24V bench project without spend fortune?
00:05Tested options under $43.
00:08Found top 5 cheap workhorses with near-perfect ratings.
00:12First board, MT3608 2-pack boost converter.
00:17Cost $3.75 total.
00:20Input take 2V to 24V, step up clean to 28V at 2A max.
00:25Great for tiny IoT sensor nodes, boost single lithium cell to 24V rail.
00:31High efficiency, tiny footprint, nearly 5,000 sold.
00:35Next board, 24V to 5V5 asynchronous buck module.
00:40Cost $3.63.
00:43Best feature is direct USB phone charge output.
00:46Replace old LM2596 run hot.
00:49Run cool at high load, perfect step-down power 24V 3D printer rail to Raspberry Pi.
00:56Third unit, heavy-duty sealed 12V-24V to 5V buck converter.
01:01Cost $8.52.
01:04Metal potted case make waterproof, handle up to 15A continuous without fan.
01:10Buy this for car, truck, or outdoor LED strip project where vibration kill bare PCB.
01:16Fourth board, XL6019 5-i step-up module.
01:20Cost $3.51.
01:23Take 3.3V to 35V input, push stable 24V output with higher current ceiling than MT3608.
01:31Built-in MOSFET run cooler under load.
01:34Best choice when project need more boost torque for motor or solenoid.
01:38Fifth pick, generic A-36V to 5V bare wire buck converter.
01:43Cost $3.69.
01:47Offer wide-voltage swing, rock-solid 5A delivery, built-in reverse polarity protection.
01:53Wire direct into automotive 24V bus or solar bank to drive dashcam or LED array reliable.
