Nokia Unveils Bicycle-Powered Phone Charger

Nokia unveiled on Thursday a bicycle-powered phone charger.

The Nokia Bicycle Charger Kit, which can be attached to any bicycle, powers up from the pedaling motion of the bike's rider. A dynamo--the electricity generator--is powered by the front bicycle wheel as a rider pedals and transfers electricity to a charger attached to the handlebar, which a phone plugs into.

"To begin charging, a cyclist needs to travel around six kilometers per hour (four miles per hour), and while charging times will vary depending on your model of cell phone battery, a 10-minute journey at 10 kilometers per hour (six miles per hour) produces around 28 minutes of talk time or 37 hours of standby time. The faster you ride, the more battery life you generate," Nokia said in a statement.

The charger can be used to power any Nokia phone with a 2mm power jack, according to Nokia.

The kit comes with two small brackets, in addition to the charger and generator. One bracket attaches to the bicycle's handlebars to secure the charger and a cell phone holder. The other secures the small electric generator to the bike's fork.

The world's largest maker of cell phones said in a statement that its new product will provide "free and environmentally friendly electricity for mobile phones" and will likely be welcomed in areas of the world where bicycles are a transportation staple.

Priced at about $18, the charging kit is set to be available from Nokia online and Nokia phone retailers by year's end.

While its certainly newsworthy that Nokia is offering a bicycle charger, it follows others. In 2007, Motorola demonstrated a bike-powered charger at the Consumer Electronics Show. In September, Dahon unveiled the $99 Biologic FreeCharge for charging small electronic gadgets by connecting to any existing dynamo hub on a bike.

Nokia's announcement came in conjunction with the release of the Nokia C2, a cell phone capable of holding and operating two SIM cards at once to allow for separate phone numbers to be used from one device simultaneously. The dual-SIM C2 allows the user to not only switch between SIM cards, but even swap one SIM card for another, while the phone is on and working.

Battery is Here to Stay

NY Times

Coaxing the most from your gadget's power source

If you’re a recent convert to smartphones, you’re probably still discovering all the amazing things that your new BlackBerry, Android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your phone’s battery lasts.

While a standard cellphone’s charge can easily go three days or more, many smartphone owners are dismayed to learn that their new mobile toy requires charging every 24 hours, or even more often. It was great that I could use one device — my iPhone — to check my calendar and respond to multiple incoming calls during January’s Consumer Electronics Show, but I paid the price when its battery died at 2 p.m.

The answer was not to desperately search for an electrical outlet to recharge the phone (though I’ve done that) or to consider giving up the phone (done that, too), but rather to figure out a strategy to reduce energy consumption while still having it available for essential tasks. Whether you’re using a laptop or a smartphone, the devices can be tweaked to get the most out of its lithium-ion batteries.

Reconsider Your Network

All things being equal, the C.D.M.A. mobile standard used by Verizon uses more power than a G.S.M. network, principally used by AT&T and T-Mobile. If battery life is critical, you might want to consider G.S.M. as long as its coverage meets your needs.

Dim It

The brighter your screen, the more juice you’re using. If you’re in a dimly lit room, turn down your LCD screen’s brightness. If your device has an autodimming feature that detects the light in a room, use it. Similarly, if you use your smartphone or laptop to play music, lower the volume.

If you have a BlackBerry, the company’s holster will automatically turn off the screen when you insert the phone.

Stop Searching

It is great that you can use Bluetooth technology to connect your smartphone to a headset, or use Wi-Fi to speed up the downloading of e-mail messages. But when you’re not using that headset or not near a Wi-Fi hot spot, turn off those features on the phone or laptop.

The reason is that portable devices will continue to look for Wi-Fi or a Bluetooth headset, using power.

Similarly, put your phone to sleep when it is in standby. On an iPhone, you do so through the “Settings” icon. On a BlackBerry, use the “Manage Connections” icon.

Skip a Generation

Your smartphone is also continually looking for a cellphone signal. If you’re in a weak signal area, your phone must work even harder to find one, decreasing battery life. If you know that there is no coverage in your area, turn off your portable device’s mobile capabilities.

If your G.S.M. 3G network is not available or the signal is weak, the battery will drain faster looking for one. Consider turning off the phone’s 3G network or using the slower EDGE network instead. It will make Web access slower but won’t affect phone call quality.

Check Mail Manually

Mobile smartphones can check for e-mail messages and instant messages automatically. Or they can be set to “push” notifications as soon as they arrive in your server’s mailbox.

Both strategies can be power hogs. To increase your battery life, turn off push and increase the interval between when the phone checks for new messages. Or better, set up your phone to check for messages manually.

Turn Off Everything

The simplest way to cut power to a minimum is to put your smartphone into “airplane mode.” You turn your BlackBerry or iPhone into a music player and personal organizer, and you won’t be able to receive e-mail messages or make or receive phone calls, but you will stretch your battery.

“In airplane mode and running just the alarm clock, your iPhone battery will last up to a week,” said Kyle Wiens, co-founder of ifixit.com, an online iPhone and Mac laptop repair company.

Disable the Animations

The hotter your laptop feels, the more battery power it is using. And one of the biggest users of power is Flash animation, the technology behind many online videos and animated ads. To improve battery life, disable Flash when not using wall power. BashFlash and ClicktoFlash for Macs and Flashblock for PC are programs that will automatically restrict Flash.

Get an App to Aid You

There are a number of applications that can help monitor battery life and shut off various functions that cut down on a mobile device’s effective power.

Battery Go and myBatteryLife tell iPhone owners how much charge they have left and how that power translates into minutes of talk time, music, video and Web surfing.

NB BattStat alerts BlackBerry owners to the amount of cell phone battery charge remaining, as well as the battery’s temperature. (Hot batteries lose power more quickly.) The device can be set to vibrate or sound when a predetermined low battery level is reached.

Radio Saver will monitor your BlackBerry’s mobile coverage and shut off the device’s mobile circuitry when you are out of range of a cellular signal.

Best BatterySaver allows owners of mobile phones using the Symbian operating system (including models from Nokia and Sony Ericsson) to create battery-saving profiles. For example, certain features can be automatically turned on when the phone is connected to a wall plug, or Bluetooth can be automatically disconnected when the battery charge drops below a certain level.

For the laptop battery, programs like Battery Health Monitor (Mac) and Laptop Battery Power Monitor (PC) keep track of battery charge and estimate how many more times you’ll be able to recharge your battery.

Realize the End Will Come

The older generation of nickel cadmium laptop computer batteries suffered from memory issues; if you didn’t fully charge and discharge one, it would hold a progressively smaller amount of juice.

Today’s lithium-ion batteries don’t suffer from memory loss, so it is safe to top off a battery.

Lithium-ion batteries cannot be overcharged; a device’s circuitry cuts off the power when they are full. However, manufacturers still recommend that a laptop not be continually connected to power once the battery is at its capacity. If a laptop won’t be used for several months, it should be stored with the battery in a 50 percent charge state.

All batteries can be fully charged and discharged for a fixed number of cycles; lithium ion batteries typically last between 300 and 500 cycles. Information on the number of cycles can be obtained at manufacturers’ Web sites, or at batteryuniversity.com.

No matter how well you husband your rechargeable battery resources, there comes a time when you’ll need to send your battery to its final resting place.

Like most things nearing the end of their life, your battery will stay awake less and sleep more. “If your battery lasts only an hour after you’ve charged it,” said Anthony Magnabosco, owner of Milliamp.com, a battery replacement company, “you know its time is up.”
