直流电逆变器可以变220v吗

直流12v可以通过逆变器逆变为220V来使用。 但是12v电源的电流大小决定220v用电器的功率。 而容量大小决定用电器的使用时间。 所以要看12V直流电的来源!如果电流过小咋没有逆变意义。 这点需要注意。 看了一下描述，题主实在学校寝室用，学校寝室大多数晚上到一定时间后会拉闸限电的。 这个时候就会很不方便，例如手机充电，笔记本电脑供电等。 这种情况可以根据自己用电量大小来匹配逆变器，电瓶等。 但是大功率电器还不要想着逆变这条路了！ 超过1000瓦的用电器，使用逆变器都是不方便的。 需要更大容量的电瓶，更大的逆变器，充电器。 整体造价过高，体积过大，不适合使用。Is 220v more dangerous than 110v?But before you elevate 220V over 110V, you need to realize that 220V is more dangerous than 110V. 220V delivers a higher current which is more likely to kill you than 110V systems. As far as the average electrician is concerned, 110V is safer to work with than 220V. Most homes in the US rely on 110V.. What is 220v used for?220-volt outlets are the most powerful plugs that you’ll find in most residential homes around the United States. These plugs are meant for ovens, dryers and other high-powered appliances that you simply can’t power with a standard 110V outlet.. What is the difference between 110v and 220v?When comparing 110-volt with 220-volt circuits, you have to keep in mind that they both essentially do the same thing. That is, they carry the voltage to power electrical outlets. The equation is as follows: Power = Voltage x Current, with current measured in amps. When 220v wiring is used, less current is required than with 110v wiring.. What is the cost of adding a 220V outlet to your home?Determining the overall cost of adding a 220V outlet to your home is difficult to do and depends on a bunch of factors. A short run might be done for as little as $400, while the long run might cost you closer to $1]
