I design electronics and can not fit all you would need into this small space. So let's keep it simple. Use the parts listed for your machine from its maker and it will be fine.
I seek a cheap car lighter-socket source charger for my Gateway LT2021. The manual says the AC charger gives out 18 volts, The AC charger cover says it gives 19 Volts, the battery pack says it runs at 11.1 volts. An available ACER car charger product seems ok as to the 19 volts, but i wonder if the plug is right for my Gateway LT (which Gateway says is an Acer product anyway). Has anyone got the inside facts on this, any experience or knowledge on substituting these products?
