Phoenix Wireless Bluetooth Speaker ($99.95). The Phoenix speaker is no bigger than a coffee mug, but its sound quality is surprisingly large. It is easy to pair with a Bluetooth-enabled phone, laptop or tablet, and the rechargeable battery lets you play tunes for up to eight hours.
Nook Simple Touch ($99). Barnes & Noble's entry-level e-reader has a crisp, non-backlit display that's great for outdoor reading. The 6-inch touch screen is easy to navigate, and B&N claims the device will run for more than two months between charges. Unlike the cheapest Kindle, you won't see "special offers" -- namely, ads -- on the Simple Touch.
Apple iPhone 4 (free with a two-year AT&T contract). Sure, this deal comes with the usual ball-and-chain: a contract that costs $60 or more per month. But if you're shopping for someone who's on your plan and dying for an iPhone, the iPhone 4 is a cheapskate's delight.
Motorola Droid Razr Maxx 4G ($50 on Amazon with a two-year Verizon Wireless contract). This bargain Android phone has plenty of high-end features, including speedy 4G LTE wireless, a bright 4.3-inch display, and an 8-megapixel rear camera. But its best feature is its battery, which delivers up to 21 hours of talk time.
Nokia Lumia 900 ($50 with a two-year AT&T contract). Microsoft's Windows Phone software rivals the iPhone and Android in sophistication and simplicity. The Nokia Lumia is cheap and stylish -- a good phone at a great price.
Apple iPhone 5 case ($25 to $30). Did someone on your gift list just get an iPhone 5? A protective case is a frugal way to show you care. The Moshi Origo ($25) is a snug silicone shell. The Cygnett UrbanShield ($30) is a slim carbon-fiber case with a screen protector.
PowerGen Dual USB Port 2A car charger (Amazon.com; $10). The PowerGen plugs into the cigarette lighter and can power two electronic gadgets simultaneously. It lists for $30.
Apple Wireless Keyboard ($69). The iPad is nifty for reading books and watching videos but lousy for long-form writing. Wordsmiths need a physical keyboard. Apple's $69 wireless model connects to the iPad via Bluetooth, runs on two AA batteries and automatically powers down when idle.
Sony CycleEnergy (about $60 to $100). Smart phones are notoriously power-hungry, and some run for only a few hours between charges. Sony CycleEnergy is an external battery that's easy to pack alongside a handset.
