A portable charger can help you to save a bundle on gas

Though many people plug their mobile devices into their cars, they may be burning more gas than they know.

Many people have shrugged off the need for a portable charger due to the fact that they have an adaptor or a USB port that allows them to simply plug their devices into their vehicles so they can charge them up during their daily commutes and any other trips they need to make.

However, that technique may be more costly and may have a far greater impact on the environment than expected.

It has recently been pointed out in a number of reports that driving while talking on a cell phone isn’t the only harmful thing that these devices can do when they are used in vehicles. Even when the driver isn’t actively using them, if a smartphone is plugged into a car and is charging, instead of using a portable charger, it actually reduces the mileage of the vehicle in a measurable way. How much? According to a retired General Motors Co. engineering exec who studies power usage in vehicles, Jon Bereisa, people charging their smartphones in their cars are slashing their fuel efficiency by 0.03 miles per gallon of gasoline.

A portable charger is now seen as the best tool to avoid this harm to the environment and a driver’s wallet.

Portable Chargers - Gas SavingsWhen considering the number of vehicles and smartphones across the United States, Bereisa’s calculations show that charging using a car instead of an external battery pack could actually send an additional 970,000 tons of global warming-boosting carbon dioxide into the air.

That said, according to Delphi Automotive Plc vice president of engineering and program management, Mary Gustanski, “Do I think we’re at peak USB? No.” She added that “We’ll get more and more creative to not only allow you to connect with USB but also to connect wireless. Consumers want their car to be just like their home.”

While mobile technology may be evolving so that it will one day offer a solution that won’t have nearly as much of a negative impact on fuel consumption, until that day has come, a portable that fits easily in a pocket, handbag or glove compartment might be the ideal solution for fuel economy-conscious drivers who care about the environment and who are hoping to spend as little as possible at the pumps.

Study shows that tablet computers are causing insomnia

Though it has long been believed that light interrupts sleep, this research focused specifically on mobile device screens.

Scientists and doctors have known for many years that exposure to light can interrupt a person’s natural sleep patterns and make it harder to obtain the rest we need, but recently the light from tablet computers was put to the test by a team of researchers from the University of Bergen.

What they found was that people who use tablets and other mobile devices causes harm even when used in the dark.

The researchers looked into the impact of using tablet computers at bedtime when compared to reading a traditional print book. What the scientists discovered was that after reading a tablet screen for only 30 minutes while in bed, a negative impact on sleep can occur. The results of this study were published within the Sleep Medicine journal. The intention of the research was to determine whether the backlighting of the screens of mobile devices actually had a meaningful impact on the quality of sleep a user would receive.

The researchers compared the use of tablet computers with the results from people reading print books.

Tablet Computers Study - InsomniaThe study involved the participation of 16 students with an average age of 25.1 years. The research participants were permitted to sleep in their own homes and beds in order to ensure that the results were not compromised by an alteration in the participant’s sleep environment. The researchers then used a polysomnography tool in order to be able to detect sleep disorders in any of the participants. Before the study, none of the participants suffered from sleep struggles.

When the participants read from print books, the problem with sleep struggles was deemed nonexistent among the participants who already did not have problems with insomnia.

On the other hand, the tablet computers appeared to have an effect on the level of sleepiness of the users. It is suspected that the light emitted from the device screen may have played a role in this impact. That said, it’s important to note that while it may have taken more time for tablet users to doze off, the duration of sleep was the same regardless of the use of a digital screen or a print book.
