Notebook AC adapters: higher wattage = faster recharge time?
I want to get a 2nd Universal AC adapter for my Toshiba laptop, which came with a 75w AC adapter (15V, 5A). I see 90w Universal AC adapter models that claim "recharge up to 20% faster," which I assume refers to when you're using the laptop and recharging the battery at the same time.
My question is...if my Toshiba laptop came with a 75w AC adapter, is it designed to use only a maximum of 75w power? Or is it capable of drawing as much power as the AC adapter can provide?
