Works great to float charge my car battery with limited current.

Like another reviewer said, this module runs hot. I had to mount a 50mm fan on top to run testing, and only up to 4 amps. Buck/boost performance looked normal with about a 30mv drop going into boost mode as the input voltage dropped. Had to adjust my scope to look at noise. It's usually in the mv range, but this ran over 3 volts peak to peak over the entire range of operation (17 to 10V input; 12.6V output). I bought and tested 4 different brands of buck/boost modules. The Jacobs Parts and the Drok both had far better efficency solving the heat problem (both use LTC3780 chips). The Drok has input and output filters included which dropped the noise to 130-180 mv over my operating range. All of this testing was done with a fixed 4A load. Don't expect to get power ratings from any of these modules as stated. These ratings are peak power and are typically twice the continuous power rating of the devices.

I was a little worried at first with using it on my Raspberry pi or my Jetson nano for noise on the output, but after using them for multiple hours with no noticeable temp difference from feel. I was less worried, after a little bit I did add on some capacitors on the output just to be safe but voltage was holding accuretly even while my batteries were dying.

I bought this buck/boost converter after trying several other unreliable converters (others failed to hold their output voltage steady under load, and/or dipped/spiked in voltage after power-on). This buck/boost converter seems to give a very robust and stable voltage output compared to the others, so finally my search is over. However, there's a good reason why there are two big heatsinks on this unit (and why I'm giving it 4 stars): it gets very hot to the touch, even when operating well under-spec. I'm dropping 29V input to 24V@1A, and I'm concerned about the temperature both heatsinks are reaching. I may need to mount a cooling fan.
