For example, if the max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current. ## Features - Input voltage range: DC 8V-40V; Output voltage: DC 12V(non-adjustable); Output current: 20A; Output power 240W. - High conversion efficiency: Synchronization rectification technology-multiple intelligent protection function with high conversion efficiency and stability.

Not hard to install. *by R***N on Reviewed in the United States on June 2, 2023* I bought this for my 48 volt electric golf cart. The guy that refurbished it hooked the light kit to two of the batteries. That meant that whenever I was using the lights, two of the batteries were getting used more than the other 4. I did not like that, so I bought this converter along with a fuse box to hook the lights to. I hooked mine up with a relay and used the voltage from the ignition key to trip the relay so that this device was only powered when the key is on. This saves on battery power being used when you are not using the cart. It was a fairly straight forward install and I had no trouble. Works as it should and I recommend it so far. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works well *by B***D on Reviewed in the United States on June 7, 2023* Works well and I have had no issues.
