Supercapacitors (ultracapacitors, supercapacitors) are a new type of rechargeable batteries which are characterized by a very short time of recharge, but nevertheless withstand tens of thousands of charge / discharge cycles.
One of the first gadgets that use the similar technology, is a flashlight with a long name 5.11 Light For Life Tactical Series UC3.400. This device is charging for just 90 seconds and is able to work after that for 90 minutes without interruption, providing illumination of 90 lumens.
You can recharge this gadget for 50 thousand times, it does not have any problems relating to degradation of the battery or the “memory effect”.
The preliminary cost of such a flashlight is 170 dollars.
I’d like to believe that soon ultracapacitors will be widely used as batteries for mobile phones and other electronic gadgets, as 90 seconds of charging is really great.
We haven’t written about chargers for a long time. But we absolutely do not want to present just another gadget “charging a dozen phones from one socket”, as there are too many of them already. And there are few people who have more than five phones / gadgets / players to charge at home. And this is not the problem anymore. Quite another thing is the road. Charging, especially emergently, on the road always caused some difficulties. This gadget is just for such a case.
If you hike for a long time, and the battery of the phone is low, and you cannot see any markings in the dark, which will help your friends to find you and you can’t get a taxi- it would be better to have a handy USB Power Bar. This little gadget is a battery that can recharge your mobile phone, and at the same time, a flashlight, allowing not to get lost in the darkness.
The kit comes with 7 various adapters for the most common models of mobile phones.
You can buy battery-flashlight for $32 in USBGeek store.
Danish electronics manufacturer Bang & Olufsen has announced its decision to begin production of mobile phones and even some types of equipment such as DVD-drives. Now the company is going through difficult times (again this global financial crisis). It seems that marketers realized that “people want to spend less on phones”, – said Karollina Malanezia, analyst of “Gartner Telecoms”.
However, the company would likely be able to stay afloat even releasing phones for 800 euros, paying special attention to their design or shell materials.
Of course, the demand for mobile phones is still outstripping, but few people want to throw their money away, buying Serenata.
So we don’t know the reason, but we will unlikely see new mobile phones from the company Bang & Olufsen. But, nevertheless, it is nice to know that somewhere on the shelves, are such rarities as Serene and Serenata.
Good news for lovers of bicycles. With the help of their two-wheeled friend, soon they will be able to charge iPod, mobile phones or other portable gadgets with OHM Personal Energy Device.
For its work it is enough to consolidate the special magnets on the spokes of the wheels, install the charger and press the pedal. OHM Personal Energy Device has a built-in battery with a capacity of 1200 mA / h, the rate of charge depends only on the cyclist.
There is one “but”: OHM Personal Energy Device is still under development, but I would like to believe that such a useful gadget will find its place under the sun.
The widespread use of mobile phones has already made a habit of listening to personal problems of passengers, or simply people who are near. In some countries the government tries to deal with people who talk too loudly on the phone, or prohibit the use of mobile phones in the transport or public places. In other countries they put “phone booths” for talking on mobile phone. But what if they have limited talking time on mobile phones and users do not follow the rules? Just muffle the signal.
Portable muffler of signals works with all types of signals: GSM, DCS, PCS, PHS, DECT, CDMA, and even 3G. Operating range is up to 10 meters. Battery life is up to 1,5 hours. It can be carried in any pocket (5,8 x 11,8 x 2,2 cm).
But the opportunity to stay in silence is not cheap. The gadget is sold online for $246.
The European Commission has stated that the leading manufacturers of mobile phones should come to an agreement and adopt a microUSB port, as a universal charger connector.
This will allow people to use one charger for all phones in the house.
This is not only convenient, but also prevents pollution. More than 4,000 tons of accessories are thrown out each year: people are changing phones and do not store accessories of their old phones.
Many companies such as Nokia, Samsung, LG, Motorola, RIM and others have begun to equipp phones with microUSB.
Nowadays, nobody is surprised that the production of smart phones is increasing in comparison with ordinary mobile phones, whose amounts are constantly decreasing. In 2008 131 million Symbian smartphones was sold in the world, while by 2013, annual sales volume will exceed up to 300 million.
Parks Associates, a company involved in research industry, predicts significant growth in the market of smartphones in the near future. According to polls, modern consumers prefer smart phones, because they combine an application for work and rest. In other words, people like toys, with which you can still call. In addition, the growth of a variety of applications for such devices is also a strong argument in favor of the acquisition of smartphones.
The forecast made by Parks Associates for 2013, provides that the number of smartphones sold worldwide, will exceed 1.1 billion. By this time, each resident of the western countries will have a smartphone, and after a short period of time they will spread all over the world.
Thus, after ten years, every existing cell phone will qualify as a smartphone by the standards of our time. Of course, by that time, most likely, you’ll see something new and smart phones will be out of fashion.
