When you are on a long road trip or in a traffic jam during a daily-commute , it may seem harmless to connect your phone to your car's USB port.But unless you really need to use your phone,charging(充电)your iphone during your commute could be a big mistake.
Why? For starters,the USB port in our car probably provides less electricity than your phone really needs to charge.As a result,your phone might stop working while it charges.
Many people may notice that on their way home from work their phone charged very little during their 30-60 minute commute,"says Brad Nichols,an engineer at Staymobile."It is mostly because that the phone is using more power than the car charger isproviding it."
Nichols also says that your phone could receive too much power,especially if you are using a cigarette lighter port to charge up.Most cigarette lighters can provide more power than most chargers can afford.If a charger cannot keep providing the proper power, it may make the phone broken.
Charging your phone could do harm to your car's battery(电池),too.This usually isn't a big deal for those who own new cars with healthy batteries,Nichols says.But if your car is older,you might not want to charge your phone through its USB port.
Most importantly,it's not safe to use your phone while driving."Anytime a person's hands leave the wheel or eyes leave the road,it becomes dangerous for them and the other people around them," Nichols points out.Bottom line:Play it safe,and wait until you get home to charge your phone.
I am worried about my teeth. My front teeth are so big that they almost look like buckteeth(龅牙). When I take photos,I never laugh. I am also afraid my classmates will laugh at me. If I had smaller teeth like other people, I would be very happy. ( Mari, Lima, Peru) | |
I want to change my pessimistic attitude(悲观的态度) to life. Sometimes, things are not that bad, but I take everything too seriously. Once, I thought I didn't do well in an exam. I became very sad. But when I saw the result, it was not as bad as I thought. I worried about it too much. I think I shouldn't be so pessimistic. ( Troy, London, UK) | |
I want to change my bad temper(脾气). I often get angry and hurt the people I love. Every time my mother cares about me, I think she talks too much. Sometimes, I even argue with her. But I know ▲ . I shouldn't do that. I will try to change my temper. ( Jake, Ottawa, Canada) | |
I often dream about having long legs. They would make me look more beautiful, and help me run faster. I like running and always join the running races at school. But other runners always pass me during the big race. I try my best, but it doesn't work because of my short legs. So I want to have longer legs. ( Nancy, Sydney, Australia) |
