So i have the RC car which runs on a rechargeable 3.6v, 500ma Ni-Cd battery. The car came with a charger that is rated 4.8v, 250ma output. The problem is the charger is not working anymore and i really don't want to lose the car. I have a mobilephone charger which is rated 5v, 500ma output. The question is can i use mobile phone charger in place of the RC car Charger...??
