Daygreen 12V Step Up 24V 10A Power Module Voltage Regulator DC DC Boost Converter 240W, Non-Isolated

Good quality, very robust. Indestructible. I bought 25 for a small product run on something I make for the agricultural market. All exactly the same and fully functional - showing me they have the manufacturing process under strict control. I torture tested one of these and it cant be broken as far as I can see. It can instantaneously source more than 10A output which is what happens when a large contactor gets energized in my application.. Overcurrent is tolerated and leads to voltage foldback - not a complete inturruptions of output - which is what I needed.

Like some sort of magic voyage wizard this little guy eats 12vdc and spits out 24vdc. I pull about 6 amps and it hardly gets warm. No fancy blinky lights, no knobs or dials to monkey with. It's as basic and foolproof as it can be. I will be buying a second one for another application I need it for.

I used this to power electric recliners in RV. Wanted to step up 12V circuit to 24 but it blows 15A fuse with initial surge current. Works fine with 12V battery out of an old computer backup unit. Will see how many cycles I can get before having to recharge.

Bought 2 of these for 2 zones of LED strip lights in my campervan. High density LEDs need 24V and my system is 12V. I run the lights every day for the past 9 months, no issues.

Bought this to step up my voltage from 12 to 24 volts for faster charging of my BluettiEB55. Works great

I used this to power multiple ubiquiti radios. It works well. The voltage stays at 24.4V and does not heat up.

Worked flawlessly for 4 days and died, no blown fuse or anything, opened up or failed internally, not what I expected after such great reviews, hoping to arrange for a replacement.

It worked like it should. I used it to charge a 24 volt lithium battery with my car battery during a power outage.
