Having multiple laptops can be a hassle, especially in a large family. Multiple laptops for your kids can become a nightmare to keep up with, and can often get damaged or lost. Buying a universal laptop charger and putting it in a common family room, like the kitchen, or living room, can create an organized family environment with one universal charging station. This will allow you to keep an eye on your kids, and manage who can use their laptop at certain times. Taking away the use of the universal laptop charger is a great way to motivate your kids to follow the rules, as they will not be able to use their laptop with out the charger.
A laptop is a great light-weight and portable way to use a computer and can handle all the power of a desktop computer in a smaller and more convenient design. Laptops come with a charger that is very different from a desktop computer power cord, and are unique to every laptop model. If your laptop charger becomes damaged or lost it may be hard to find a replacement for your original laptop charger because they’re simply too many laptop models to have a charger for each model available for sale at an electronic store.
You may be able to order your original charger from your laptop manufacturers website if they have it available; however, some companies do not give you this option. This can create a problem if you use your laptop often or have any important files and documents stored on the hard drive, because without your laptop charger you can’t use your laptop once it runs out of power. This inspired the creation of a universal laptop charger, which features many different adapters that will fit in any laptop model. If you have many laptops you can use a single universal laptop charger for each laptop, allowing you to only carry around one charger. This is a huge convenience especially if you travel a lot and carry multiple laptops with you.
Some laptops require the same brand universal laptop charger. For example; if you have a Dell laptop, you may need a specific Dell universal laptop charger. This is because there are so many different laptop models for each laptop manufacturer, new and discontinued, multiply that by at least ten laptop companies and you have a thousand different laptop chargers. This is simply too many to have available at a store or even online; therefore, a universal laptop charger can be a life-savor. Other universal laptop chargers can fit a variety of laptops and come with many adapters allowing it to fit different brands of laptops.
Before you buy a universal laptop charger make sure your laptop model is listed in the compatible models. Every universal laptop charger should have a list of laptop models that it is compatible with; however, some universal chargers support more laptop models than others.

I can definitely relate to the problems of controlling how much time my kids spend on their laptops and your idea of a universal charging station is a brilliant one!
