DC 12V Step Up to 19V 5A Boost Converter 95W DC Voltage Regulator Supply

Used to solve led flicker from my utv stator. Wish they were a little smaller but seem quality. Added a fuse on power in just in case. So far no issues. Almost zero heat when going from 14ish volts with utv running to 12v stable power. Used one for each light. I did try to use it on a video signal, did not filter out noise enough, but seems to work well for LEDs

Some radio gear cannot tolerate standard auto lead-scid voltages that can exceed 14 volts during driving. Likewise, ham radio QRP transceivers require no less than 12 volts. This sealed, no-adjustments little brick provides exactly 12 volts out, when supply voltage varies from as low as 8 to as high as 30 volts. Other wattage ranges are sold too.

I was having an issue with my solar setup for my electric fence energizer failing to work because once the energizer got more than 12 volts it just stopped working (obviously has over-voltage protection built-in). I needed a way to make sure no more than 12 volts went to the energizer. The place we bought this from had a couple of diodes in the circuit that were being used solely for their voltage drop to get the voltage from the battery down to 12 volts. That seemed hacky to me and was unreliable. I connected the input of this voltage regulator to the load output of my solar controller then connected the output of the voltage regulator to the input of the fence energizer (well actually through an on/off switch first but conceptually the same). The energizer is quite happy with the 12 volts this regulator is putting out. I have only had it for a few days so can't speak to its longevity but so far so good.

This is a great product to have I was able to build my own charging unit

When Starlink says the Mini works with 12VDC, don't believe it. I added this booster and my Mini is now rock solid. The included quick-couplers made installation a snap.

I'm reviewing the 12V -> 19V 5a converter I have a bench power supply and a load tester to test it out. My final use case is powering a portable mini-projector (which has a laughable "up to 2 hours" internal battery, which in reality doesn't last through a 1.5 hour movie) from some 12v batteries. The projector uses about 60w when charging/running. The bad: I wish this had a voltage range input. The 12v batteries can be anywhere between 11v - 14v. That's probably OK ... but who knows? A spec would be nice. Apparently their "smart chip" doesn't prevent low output voltage if the input can't handle the load. I limited the power supply current to see what would happen -- rather than shutting down, the converter just put out lower and lower voltage (and made a buzzing noise as it tried to keep up). In reality, this is probably fine. The sources I plan on using will have no problems with my 60w use case. The decent: Voltage output was 19.2v with no load, but dropped to about 18.3v with any load applied. It would be nicer if it kept the output to 19v. The good: Measured efficiency was between 92% - 96%. Nice to see it can at least reach the advertised numbers, and 96% is a great result! I didn't measure output ripple, but the output stayed pretty consistent across the range I tested: input (11v - 14v) and load (0.5a - 4a). The load tester I have isn't designed to test ripple, and I didn't really try. Eyeballing the voltage meter looked like the ripple might be fairly high (maybe 0.3v) -- but that's a terrible way to measure ripple.

I installed between '90s 8hp 2-stroke 6amp loop gen output under the cowl and boat wiring to motor. That power comes from stern boat wiring buss bar. My chart plotter and especially auto-tiller connected to same bus bar would act up when motor was even at only 25%. More than 90% problem eliminated now. Could not auto drive a straight line without it. Now, maybe 1-2 steering blips a day. Smaller motors don't have voltage regulators. I have 3 solar charge controllers so 13.8V seemed optimum to send to the 225ah battery without more regulation. I almost never run over 50% throttle. Solved a pretty serious problem.

I got this when the Starlink Mini came out so there were no dedicated power converters. It worked fine for about a year. Unfortunately, when it failed it killed the Starlink Mini.

Used on Emmo G5 E-scooter to reduce 48 V to 12 V for lighting system and horn. Unit is located in front near steering column.

Does not do what's advertised
