Does anyone have experience with voltage converters? My main battery is LiFePo5 with ~11-13.4V...
now i'm thinking if it makes sense to get aconverters who can give me stable output to run those things. i saw they use 'switching frequencies'. would it ad noise? cheers |

There is nothing more stable - or noiseless than a battery! So why bother adding anything else - especially something that could add noise to your system? It will also waste energy.Really, don't bother! |

Its probably simplest to just use a dc to ac inverter and use the adaptor which came with the product, but if it's for a multi amp DC audio system then consider something like:- Edited by Lucasdude - 20 February 2022 at 6:47pm |

I agree with this. I have used a fair selection of products in my van that were labelled as 12vcd/1a, the same as the 4x4 mini, at various voltages up to around 14v, and non of them broke. However, that's not to say that your 4x4 mini will be as tolerant so I'm not recommending you try it!

I would be very surprised if it couldn't cope with a couple of Volts either side of 12V as it's going to be generating other supply rails internally anyway. However a quick inspection of the internals by an electronic engineer would soon confirm either way.

Yes - there are some ics that operate at 5V, 3V, or even less that can be very sensitive to the supplied voltage and need regulators, but most of the stuff that works off 12V or 15V will happily take a couple of volts more (or less). And most of the AC adaptors you get are "nominal", ie they are not going to give exactly 9V or 12V, etc.

Should be good for 12V, +-3V.
