A universal laptop charger is an excellent idea when you have multiple devices in a home and everyone has his or her own favourite brand. When the charger wears out and needs replacement or when a spare is needed, one that works with multiple brands is the practical choice. They come with multiple tips to ensure that one fits your device. It is ideal when you are traveling or if you carry your laptop from work or school to home. Never run out of power in the middle of a project when your charging unit is in your bag.
Find new or used chargers from sellers on eBay. You may want to trade in your laptop or netbook someday, but you want to keep the universal laptop charger forever.
