If the original charger for your máy tính broke or you just cant find it, you may consider using a different charger. Most of us have dozens of chargers lying around, and once our original chargers break, we often look at those old ones or look for help on the internet. But, can you use a máy tính charger with a higher wattage than the máy tính? If your máy tính charger has higher wattage than your máy tính, you should be able to use it without a problem, as long as several other conditions are met. For example, the connector has to match the máy tính and the amperage has to be equal to or higher than the laptops amperage. Of course, using the charger that was specifically designed for your máy tính is always best. Click here to search máy tính charges on Amazon. There are even more caveats that you have to be aware of, as well as some precautions to take. Its always best to be informed and to know as much as you can about a subject before you try something new. So, if you want to use a charger with a higher wattage than your máy tính, read on. Does Wattage Matter for a Laptop Charger?If you want to charge your máy tính with a charger thats not its original one, you may have to look at several factors, including wattage. Here are some things to consider. The PlugThe most important thing for a charger is that its plug matches the máy tính. If it doesnt, then nothing will work. For example, most phones have similar chargers and most can be changed easily without bothering with other elements like wattage or amperage. But, laptops are a bit different since most usually come with different plugs. Each manufacturer could have a proprietary plug and this creates issues. There are all kinds of connectors, from round ones to USB ones, all in different sizes. If your charger matches your máy tính, you are already halfway there and you should have fewer problems charging with it. If none of the chargers you have fit your máy tính, you will probably have to order the right one and pay for it, and these can get expensive sometimes, but it depends on the manufacturer. Once you find out whether it matches or not, its time to move on to more technical details, and see if the setup you are going for can work. These technical details include wattage, amperage, and voltage. And if they are not suitable for your máy tính, then you might cause a small fire in your room. So, you have to be precise and careful. The VoltageThe voltage comes first and you will likely find it on the box thats attached to your charger. This box is called the power brick. The voltage number defines what will pull the power to your device. If the number on the power brick marked for voltage doesnt match that on your máy tính, you could cause a big problem and destroy your equipment. Laptops generally have around 15V (more or less) and most chargers will match that. The voltage is a very important factor and it should match the voltage on the máy tính. Find the voltage of your máy tính in the papers and guides that came with it, on its box, or even perhaps at the bottom of it. The AmperageAmperage is another important factor in this process. The amperage states how much volume of power the máy tính can take and the charger can provide. Youll find the amperage on the power brick as well and in the papers that came with your máy tính. If you want the charger to work for your máy tính, you need to make sure that these numbers match. At the very least, the amperage on the charger can be a bit bigger, but not by a lot. It should never be lower than the one on your máy tính. Otherwise, you could start a fire or cause damage to your equipment. The WattageThe wattage is the final important factor. The wattage is the amount of power a device draws and needs, so your charger should provide the same or higher amount of power. Youll find these numbers on your power brick as well and on the bottom of your máy tính. So, make sure that they match or that the one on the charger is higher than the one on the máy tính. Most laptops will need between 45 and 10 watts of power, so if the charger provides less by any chance, dont use it. Maybe your charger isnt showing the watts, but if the amps and the voltage match well, you shouldnt have an issue. Still, if you notice smoke or overheating, remove the charger from the máy tính immediately. Other Tips When Matching a Charger to a LaptopOf course, this is not the complete list of things that youll need to check when looking for a new charger to buy, but if you just need to know whether one of your chargers will work on a máy tính, this will be enough. Because chargers are often expensive, you may start looking for one that doesnt necessarily come from the manufacturer. Knock-offs come in all sorts of shapes and sizes, but they are not always the best option for you. They will break often and they might even damage your equipment. They are not the safest either since there are basically no standards in the knock-off industry. These chargers will also not work well they wont charge. So, your máy tính may sit on the charger all day long and nothing will ever happen. Its better to go with the original chargers or a charger from another brand that works on your máy tính. Can I Use a 90-Watt Charger on a 45-Watt Laptop?If you want to use a 90-Watt charger on a 45-Watt máy tính, you should know that this is possible. Wattage defines how much power a device can draw. In this case, your máy tính has a wattage of 45 Watts, so it will draw that much power from the charger. Your charger can take it and it wont get too hot during the charging process. In fact, youll have quite a smooth experience with this. Of course, you have to consider the amperage as well. The amperage should match as well. If it cant match, then it should be higher. Wattage is a measurement that will tell you how much power a device can draw, but the amperage defines the volume of electricity that flows to your máy tính at once. Naturally, make sure that the plugs are matching too. On the other hand, if you have a máy tính charger with 45 Watts and a máy tính with 90 Watts, you would not be able to use them together. The problem here is that your charger wouldnt have enough power to give to your máy tính and it would work harder than it has to provide it and match the needs of your máy tính. All of that heat would cause various issues like a fire, overheating of the charger, and so on. If the amperage doesnt match or is higher than your laptops amperage, you would also have issues. Your máy tính would require a volume of electricity that your charger simply wouldnt be able to provide. So, stick to higher or equal when it comes to connecting chargers and laptops. ConclusionSo, there you have it, as long as your amperage and wattage are higher than the one on your máy tính, you should be able to use it properly. Of course, first, make sure that the plugs are right for your máy tính. However, dont try to do the opposite and plug a charger with lower wattage than your máy tính into it. This could cause some serious damage to your equipment at best, and at worst, it could cause a fire. So, be careful when tampering with electronic equipment or you might get hurt and cause damage. Always take the time to get informed on what you are trying to do or ask an expert for their help. For more, check out Can I Use Water to Clean My Laptop Screen? (With Two Alternatives).
