Review on 💡 DAOKI 5PCS XL6009 DC-DC Adjustable Step-up Boost Power Converter Module as a Replacement for LM2577 by Rafael Gomez

Works great. I'm supplying 13.2V and setting the output to 29.5V. I'm supplying a circuit that draws less than 500mA so I'm using 15W max. I've also used it on a newer 12V wall wart model to easily boosted to the same 29.5V. I used a modified wall wart device to replace the stock wall warts that failed during a thunderstorm. The 29.5V wiring is very long and prone to surges caused by lightning. This caused the original wart to fail, but that circuit has not yet died, although other devices have died. Also, black ants settled in the remote devices, causing the system to crash, and after measuring the input and output voltage of the booster circuit, I worried that they or the 12 volt wart had failed. But after cleaning the anthill. The chain immediately went back to business. I didn't expect it to be so resilient to short circuit conditions. Looks like he has his current limited or a 12 volt wall wart, can't tell which. They don't advertise that they accept such violence, but it's nice that it happened. However, I also connected the input voltage in reverse, in this case they pop and smoke. I didn't leave it plugged in long enough to know if they caught fire. A 5-pack is good for bugs like this and primarily for experimentation. You need a very small flat head screwdriver to adjust the output voltage level. 30 ohm group as a boost circuit load and there was very little deviation from my 29.5, I think it went as high as 29.3. It was a calculated load of just under 1 A and just under 30 watts. The resistors started to heat up, but the booster circuit worked fine.
