In our daily life, there will be a lot of things that often do not use, but need to be more urgent, so we usually put up a few in the home, do not need to go out when the use of the purchase, to save a lot of time. I saw the adapter in the supermarket doing activities at the last time. I just grabbed several of them and put them in my home, which has been useless for a long time. Just before the day before the computer did the homework, the computer suddenly broke and needed a adapter , the husband let me out to buy, just I said that the last time I went to the supermarket bought a few, I took out to let him install, the computer can be used normally, the child is also very happy to continue to do the homework .
