I have a brand new Coleman lantern that I got from a friend. It has a rechargable battery in it that is dead now. He said he lost the power supply charger for it. It t akes an output of 13.5V and 300ma adapter to charge it. I have collected many power units over the years and have many that I can fit into this slot on the bottom of the lantern. They are many different configurations. What is the range of voltages and ma can I use to charge this lantern without burning down the house?

Can I get a voltage range and a ma range. I have some that are close like 12V and 300ma and various others. What is more important the V or the ma(milliamps)?
