Daily deal – Kensington iPod and iPhone battery pack for $26.24 (after rebate)

My daily deal for today is for a product I reviewed last year. The Kensington Mini battery pack and charger for iPod and iPhone is (as the name implies), a portable backup battery pack for your iPod or iPhone.

The device can charge off any USB charger or USB port, and comes complete with a retractable miniUSB charging cable.

The battery pack can add up to about 30 hours of music playtime, 6 hours of video, or 3 hours of talk time. To start charging your device, you simply plug the battery pack into the dock connector of your iPod.

When I wrote my review, this product retailed for about $47. It has since come down in price, and is on sale at Buy.com for $36.24. The deal gets even sweeter once you apply the Kensington $10 rebate to your purchase.

The rebate form is valid for purchases made till January 11th, so don’t wait too long. Buy.com will ship the unit for free.

Daily deal – Shure I2C-MP noise isolating headset for $39.69

My daily deal for today is for the Shure I2C-MP stereo noise isolating headphones. These headphones combine passive noise isolating headphones with a microphone. The combination means you can use them on your regular MP3 player as well as a compatible mobile phone or smartphone.

They have been tested with the Apple iPhone and the Blackberry Curve, but should work on any phone with a 3.5mm stereo headset jack. If you plan to use these headphones on the “old” iPhone, you’ll need to order a headphone adapter, thanks to the silly recessed headphone jack design.

These headphones normally retail for a little over $100, but Amazon.com has them on clearance for just $39.96. Of course, at this low price there is a slight trade-off; they do not feature a call pickup/hangup button. This means you’ll have to reach for your phone to control the call.

Despite that minor detail, under $40 for a pair of Shure noise isolating headphones is quite a bargain. The advantage of noise isolating headphones is that they are very light, and they don’t require batteries to operate.

The headphones include a personal fit-kit consisting of several different earpieces and a nice Shure carrying case.

Remember, Amazon ships their own items for free (when over $25), and Amazon Prime members can get these headphones sent with 2-day shipping for free.

Daily deal – APC UPB10 battery pack for $14.95

My daily deal for today is the kind of product you should buy first, then decide whether you really need it.

The APC UPB10 is a small external Lithium-Ion battery pack suitable for charging most USB powered devices. This includes most Blackberry devices, iPod devices, the iPhone and almost every other smartphone on the market.

The device comes with a standard USB cable for charging off your PC or existing USB charger. To charge your device, you simply plug it into the UPB10 and let it do its work.

The 10Wh capacity of the battery is sufficient to fully charge most devices once or twice.

A device like this can be a true lifesaver, if you have ever found yourself stranded at an airport with a dead phone , or mid-flight with a dead iPod, you’ll learn to appreciate the ability to breathe some life back into your gadgets. Just remember to carry your USB cable wherever you go, or to buy a spare.

The UPB10 normally retails for about $50, but Frys.com has it on sale for just $14.95. Shipping is about $6 for most destinations, and lucky readers with a local Fry’s store can opt for in-store pickup to save the shipping costs.

Public service announcement: stop using your iPhone 3G charger!

Our friends at Engadget are reporting on a potentially dangerous situation with the charger included with the iPhone 3G. Apparently the prongs on the tiny Apple USB charger are prone to staying in your outlet when you unplug it, creating the kind of situation you’d rather avoid.

Apple.com has all the information you need, including where you can order a new charger. The replacements will be shipped out starting October 10th, which is also the date you’ll be able to walk into the local Apple store and leave with the new version. The defective charger was only included with the iPhone sold in the US, Mexico, Canada, Japan and various Latin American countries.

Apple strongly suggests that you cease using the charger, and simply use the included USB cable to charge your phone using your computer. Alternatively, you can use the previous generation charger (with the folding prongs) or almost any other generic USB charger.

Stay safe, and if you do happen to run into the problem described, be sure to disconnect the power before even thinking of trying to recover the broken prong from your outlet!
