Certificates: CE/RoHS, 1 year warranty, lifetime up to 100,000 hours. Package included: 1 x DC 8V/40V to12V 10A Converter Questions: How to choose the correct current for loads? 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. Review: Pretty nice little unit. - Nice package. The 10 amp model 12v to 12v gets just a little warm with a 3 amp load - just a little warm to the touch. It does draw a ton of inrush current when first turned on. Running it from a 5 amp lab supply with a 0.5 amp load the lab supply did an over-current shutdown. It is fine operating from a car battery, though. I'll be using this to power an 8" telescope, camera, filter wheel, and focuser. Review: Sand rail. Cooking ignition coils - Works great. Completely evened out my over voltage problem. ## Features - Input voltage range: DC 8V-40V; Output voltage: DC 12V(non-adjustable); Output current: 10A; Output power 120W. - High conversion efficiency: Synchronization rectification technology-multiple intelligent protection function with high conversion efficiency and stability.
