00:00Need cheap DC-DC boost modules under 15 bucks to step up low-voltage sensors, relays, or lighting circuits and
00:0672-volt battery rigs?
00:08Found 5 top-rated units tested for micropower jobs on big builds.
00:13None touch 72 volts raw step main pack down first, then use these cheap boards for precise auxiliary tuning.
00:20First, standard MT36085 pack at 433.
00:24Takes 2-24 volts in, kicks out up to 28 volts at 2 amps peak.
00:30Cheap bulk pack for bench testing, tiny LED strips, or running 12-volt trigger circuits off low 5-volt taps.
00:36Burn 1 out, for backups left in drawer.
00:40Second option gives 10 MT3608 boards for 630, but adds USB-C and micro-USB ports directly to input rails.
00:48Makes bench powering dead easy with standard phone cables before hardwiring.
00:53Outputs up to 28 volts.
00:56Perfect bulk stock if wiring lots of 5-volt accessories across multiple sub-harnesses.
01:01Third pick is 35-watt buck boost module at 719.
01:06Does both up and down, input 5.5 to 30 volts, output half-volt to 30 volts at 4 amps.
01:13Includes clear LCD screen showing input, output, current draw in real-time.
01:17Best unit here for monitoring display power or dialing exact gate voltages.
01:23Fourth is single MT3608 package at 495.
01:27Same classic 2-24 volt input, up to 28-volt output spec, built for Arduino integration or LED drivers.
01:35Costs bit more per board than multipacks, but handy if build needs one tidy board without extra loose inventory laying
01:41around.
01:42Fifth module runs beefier XL6019 chip for 389.
01:47Takes 3.3 to 35 volts and pushes out up to 24 volts continuous with 5-amp peak rating.
01:54Integrated heat-sinking handles higher thermal load better than MT3608 chips.
01:59Best choice for driving small 12-volt cooling fans or horn relays.
