  • any time you use the wrong Amperage or polarity you can mess up electrical items. Why would you want to wreck a laptop. Give it to me, I'll sell it and make some money. Hey... i might even split the money with ya.
  • I just wanted to add a bit of clarification to my brother's answer. The ampere rating refers to the amount of current the charger can safely deliver to devices plugged into it. If the charger is rated for say 10 amps and the device only need 5 amps, then the device will still only draw 5 amps. This will leave you with 5 amps worth of capacity for the charger that is just not used. You could even potentially use the unused capacity to run a different device at the same time. However, if the charger's capacity is less than that which is required for the device (let's say 3 amps for this case) then the device will try to draw more current than the charger is intended to deliver. Resistance within the charger could cause it to overheat, which can cause damage to the charger and, in extreme conditions, even cause a fire.
