Yep, different chargers have different voltage requirements. It's always a good idea to check the specs, when combining equipment from different suppliers.
About talking a risk; It's obvious, that the modification of a PC PS involve some kind of a risk (which is also mentioned in the link I supplied). But I cant see how you risk the charger - I've heard of PC PS going down, that is, they either deliver the voltage or dont deliver a voltage. Like all other PS. So that wont risk the chargers life. But I've never heard or seen a PS, that delivers a TOO HIGH voltage by accident - which would damage the charger. Nor have I heard of other chances of damaging the charger. So can you please enligthning me about in which manner a PC PS user risk the chargers life?
one thing is something may go wrong and may deliver a too high voltage by accident. I canīt say for sure if this can happen or not in regular use but I wouldnīt say this canīt happen. Most PS have an overvoltage shutdown but I think this is happening at a voltage too high for some chargers. Talk of 18-19V.
Most of the PC PS are so cheap constructions regarding design and especially electronic parts used. I know of a very good PC magazine making extensive tests with all kind of hardware and PS also. I have seen damaged PS in about each of their tests and they donīt do any crazy tests. Just everything a PS have to pass to be working OK according to all national and international rules.
What I know from personal experience:
Some years ago at the European Champs 1/10 Onroad in the UK there were some problems with the main voltage. It was somewhat higher than in other countries and due to a high load shutting on and off all the time there were bad voltage spikes which caused a lot of switching PS being damaged. Most of them (about 30) were the Victor PS. This isnīt a bad PS and way better than most PC PS but not as good as industrial PS. What happened- not only PS but also some chargers also were damaged.
What I want to say there are some extrem situations where a switching PS could go bad and damaging the nowadys expensive chargers also and you can be shure this could happen at about every bigger race if you are not using a PS made for this conditions. Working at home is an easy task for a PS as you have constant conditions at the main voltage usually.
But at the race there are lot of chargers shutting on and off all the time causing fast changing conditions for the main voltage. This is even bader as not every driver have his own power outlet but some drivers are using one line. So in the end you will have a big and fast changing voltage range where the PS have to work.
