SUPERNIGHT DC 24V Step Up to 48V 5A 240W Converter Booster Waterproof

Working just like it should, with a slight increase in water pressure.

Works as expected. We had a hacker put in 12V head lighting on the cart by sniping into ONE of the 4 12V batteries. That didn't work out too well for the long run. You can do that but it is not proper and issues with uneven charging of the battery bank and the one battery used will eventually not take a full charge. We also bought 8 watts of new LED lighting (4 watts per side) this is very sufficient as the cart is always back away from the road on wooded cart paths. So we have plenty of extra 12V power we can use for other things (radio, additional lighting, cell phone charging etc.) if we wish. 120W will not power a road legal incandescent lighting array. For those you will need to bump it up to a few hundreds watts at least. However for carts that run on cart paths off road this thing is more then sufficient. I placed a 10A resettable thermal overload on the 12V output side and a 3A in line fuse on the 48V input side to protect the wiring and used 14 ga wire. I also soldered the wiring into the non insulated crimp connectors and wrapped them with electrical tape. Shrink tubing would have been better. Should last forever. UPDATE; The idle current on these things is about 32 watts with the lights off. That is enough to sink a full charge in 5 days at best even with our 7.2KW battery bank. These should be wired in with the on/off switch on the 48V to knock down the regulator too. By the math that's about 10% of our full bank charge a day, but when you take into account the various synergies at work with these lead acid batteries in reality it is closer to 20% over a 24 hour period as these batteries are really only good for 50% discharge of their total rated capacity. If you charge at the end of every day this is not a problem. But if put few miles a day down and do not charge but every now and then this becomes a real issue. I thought the idle current would be 1-2 watts, not 32. So the solution when the switch is mounted on the dash and the regulator placed under the seat at the batteries is to run a 4 conductor lead and pass 48V through the switch and back to the regulator and the 12V conductors from the regulator to the lights and whatever. I used 4 conductor lead because I was also going to put in a batter charge indicator later. So this to me is no big deal. I will just include the modifications when I mount the charge meter.

I used this to bump the voltage for my star link so I could run a smaller wire in my canopy camper as well as not have interruption during voltage dips such as when starting a diesel heater. it works perfectly! came Packed well and the price is on point!

I use this with a fused cig lighter plug to feed 24-28v to a little tpa3116-based monoblock amp driving 8 4x6 sealed soundbar subwoofers in my car. I had the amp and the little subs so it was the cheapest way to fill in the bass a bit. As an aside despite the max output limitations (~87db/1w before cabin gain with roughly 60 watts on tap) its sound quality is on par with the SI and TC-sounds/Morel/DSP installs I've done for clients in the past. Seriously. No one-note boomy bass, just smooth articulated fill. Works great, doesn't get warm in my application (it's pretty cold around here so YMMV with heavy loads in a hot climate, but the case remains ambient) and hasn't skipped a beat. Not much to review, but worth noting that if you use it for a similar audio application involving fragile or high frequency transducers you may want to add a simple high pass filter on the amp outputs for the initial surge when turning the car on. In my application this minor thud noise doesn't matter, but anything close to dc can bypass crossover non-polarized capacitors and pop your tweeter.

Fast shipping. Looks like good quality. Unit seems very solid and sturdy. I am using this for my Starlink mini to hook it up to my batteries on my RV. After installation and hooking it up to my house batteries, the unit read 24.2 V. So far so good. I would have given it five stars if it came with some kind of directions or manual, nothing in the box except for the unit and it’s parts. Luckily, I already knew how to install it.

Muy buen convertidor, liviano y de buena calidad. Me funcionó perfecto para la lo que lo requería

UPDATE 5/26/25. I received my replacement unit and while it didn't have the high-pitched whine of the first unit, it was only able to output13.5VDC which is nowhere near the rated 24VDC output. I would not recommend this converter. During my initial testing, I connected the boost converter to the 12VDC port on a battery bank. The battery bank displayed the unit was using 50–75 Watts when not connected to a load and was emitting a high-pitched whine. I'm not sure about the expected power draw, but I expected some power draw and the whine due to the conversion circuitry I then read the output voltage of the unit using a digital multimeter, which indicated the unit was only outputting 12VDC. I then verified the polarity of all connections and double-checked that the input and output were properly connected, and then re-tested with the same result. I contacted SUPERNIGHT support, they responded quickly, and they are sending me a replacement converter. I will update my review after receiving the new converter.

Was easy to set up. Does not get too hot. Good value.

Used this to have high/low beam for led light i added onto the front of my atv, it is in contact with mud and water constantly and has not shown a single issue.

Using ths Step Up boos converter to power a DC-DC Starlink Gen 2 kit, the previous one only lasting one year before seeing the voltage drop bellow something usable. This time, I opted for a 5A rather than a 3A to give some room to extra load. Under load, which is roughly 2A, the advertised voltage drop to 45 volts out of the 48 expected. Still usable, but make you wonder if this will last a year or if it will drop too.

Not good don't buy this,,

Ok

Werkt goed heb hem gebruikt voor camper van accu naar power station Bluetti en die geeft aan met laden 195 Watt en geen 480 Watt . Groeten Johan
