Great Christmas gadgets under £100

1. Philips Power2Charge, £20 from Amazon
Sufferers of gadgetitis tend to develop a worrying secondary condition where they end up hoarding power supplies. The Power2Charge is the cure. It's a universal USB charger that can be used to power up MP3 players, smartphones, portable games consoles and a whole host of other devices.

2. Bow Wow Dog Speakers, £23 from Paramountzone
These doggie-shaped speakers put the woof into subwoofer. They might be small, but they bark out 6W of sound -- enough to keep the neighbours awake at night. Handily they're powered via a computer's USB port and you can get them in either white or black.

3. Utag Digital Dog Tag, £25 from Purityequip
These digital dog tags plug straight into a USB port and can be used to store vital information such as your emergency contact details electronically. They come encased in a weatherproof holder and can be worn either as dog tags or used as a key ring.

4. Lili Webcam, £30 from John Lewis
Who said webcams had to look boring? This cute jellyfish-shaped model is available in red, green or blue and has a 1.3-megapixel resolution. It connects to your PC via USB and shoots smooth video at up to 30 frames per second.

1. Robot Arm, £30 from Red5
Have you got a loved one who dreams of being able to recreate that Renault Picasso advert in their front room? No, us neither, but if we did we'd buy them this funky five-motor bot, which is operated via a wired controller.

2. Sega Mega Drive Handheld System, £30 from Xploder
Honey, we've shrunk the Mega Drive! This handheld recreation of Sega's blockbuster 16-bit console comes preloaded with 20 classic games, including Sonic and Knuckles, Shinobi III, Altered Beast and Golden Axe. You can even connect it to a telly for big-screen gaming.

3. Griffin iTrip AutoPilot, £35 from Amazon
There are loads of iPod FM transmitters on the market, but this one is particularly good because of its auto-scan feature. Basically it scans the FM radio spectrum to find the three best frequencies to use and then saves them automatically to three programmable preset buttons for recall later.

4. Brick USB, £25 to £35 from Firebox
The Brick is basically just a USB key, but it's the funky Lego-style design that makes it so desirable. You pull the brick apart to reveal the USB plug and can choose from three different colours and two capacities -- 2GB and 4GB.
