DC 12V Step Up to 19V 5A Boost Converter 95W DC Voltage Regulator Power Supply Converter Waterproof Module Transformer for Golf Cart Club Car Led

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

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 was used on a FIRST Robotics Competition robot to power a mini PC for vision processing. There are significant voltage drops due to the 8 motors powering the drivetrain and this would cause the PC to drop offline during competition matches. When testing this module offline it put out a consistent 12.25V with input voltage ranging from 13V all the way down to about 3V which is well below the claimed minimum of 8V. Our robot voltage drops to about 10V during matches and this past weekend our mini PC consistently stayed online during several dozen matches. I'd call that success.

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

I made a voltage mistake when I ordered a fan. This was the easy fix.

I have an old F250 with a quarter million miles on it that I don't drive much. It has a slow parasitic draw that drains the battery over 3-5 days. It's inconvenient to park near the garage and leave it on a trickle charger so I installed a solar panel on the roof. Used this DC converter to step down the ~24V solar panel to a safe 13.8V so as to not fry the electronics in my truck. Output voltage was tested with a Klein multimeter before installing. Added a 10 amp fuse for safety. It's working great!

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.

The product was dead out of the box, unfortunately I didn't try it until after the Amazon refund window, so out of luck now. I have purchased this same item before and it works fine.

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

Sam le de bonne qualité
