[QUOTE="phil d, post: 476678, member: 27126"] Some of these inverters are rubbish, unless you are spending a good chunk of money on it then don't bother. I bought one a few years ago to charge drill batteries in my van, it worked fine when connected to a battery sat on the garage floor and it charged the batteries, the problem came when it was connected in the van. Without the engine running it ran fine, start the engine however and it cut out and wouldn't work, it kept saying overvoltage. Some of these cheap chinese ones are not very good on the input and output. in the end I found mine was designed to work on 12v but it had no tolerance, so when the car engine started and the voltage increased to around 13.5 it was enough to cause it to shut down. In short, if the OP needs a power source for something as critical as it sounds then like it or not I think he's going to have to lay out a few hundred quid for a decent unit. [/QUOTE]
