Status: offline 		Hey,

After searching for quite a while on the internet for a charger i've found that the majority are designed with a 12V DC input. I was just wondering why they dont incorporate a 110V AC input aswell. I know there are chargers out there which do have inputs for both, but most dont. I can also understand why you would use DC (for instance if your out) and I know you can buy power supplies for using in your house. However there must be some other reason for not having an AC input; isnt there?

Please post your opinion.

Yet there are a few that are not, how they get away with it is still a mystery, no doubt a political pay off involved somewhere.

Thanks for insight
