Also that raises some concern because the input wires are 16awg, which is rated to handle only about 10amps at 12v. This is not to US wiring standard and could potentially cause a fire. When I asked the seller about this they simply answered "yes, it is ok" with zero explanation as to why. But the facts are it isn't technically safe with those specs. That input wire should be at least 8-10awg if using a 30amp fuse. **Q: So will this go both ways? 12v to 48v up or 48v to 12v down?** A: No, it is 12v to 48v dc step up converter **Q: Will the output be regulated, that is limited to 3a, 14 watts, regardless of the load? and with no damage to the buc?** A: Yes, this 12v to 48v converter will automatically adjust the current and power required by the device at the output, provided that the voltage of your device is 6-16v. **Q: I am looking to convert a 18V 5 amp hr RYOBI one plus drill battery to a 12V lighting for an EBIKE is this suitable for this and which one do I need?** A: Please check the model of 24V TO 12V 10A 120W Step Down,here is the ASIN: B0963J2YBD ## Frequently Bought Together - DC 12V Step Up to 48V 6A Boost Converter 288W DC Voltage Regulator Power Converter Transformer for Golf Cart Club Car Solar System - 150W GigE Passive PoE Injector with Surge Protection, Developed for Starlink pinout. - YAOSHENG Rectangular Dishy Cable Adapter to RJ45.
