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

Works as described, ran 24 hrs straight no problem, ran cool

Got the 72 watt (3 amp) unit for Starlink mini. I am able to use this with the stock cable with this (adding the barrel plug of course). The device tends to pull around 20 watts so there is plenty of capacity left and of course it can pull up to 60 watts technically.

Trying to cut down parasitic load, went from a 15amp unit down to this 3amp. 13v in 24 out. Works fine ?? I think maybe folks overloaded theirs or have high inrush current. Haven't cooked the 15amp either. This unit shows unloaded 0-.20 watt use. Where the 15 amp uses 1 watt idle. Big help if you're trying to max maximum use of WH when the sun is down. - It's running a ubiquiti LTU lite, and soon to be an LTE radio.

The first unit I received did not work properly, kept blowing fuses. Returned that one and the second one has been working properly so far.

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

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.

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.

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.
