From American food company Heinz comes this Beanzawave portable microwave. It’s the world’s smallest, portable microwave oven, measuring 7.4 inches tall x 6.2 inches wide x 5.9 inches. It’s only a prototype at the moment.

The price would be around $160 if Heinz ever decides to make this USB microwave oven, so you can have your beans anywhere.(What were they thinking with that name?) It would be convenient for those on the road since it can be powered it by a laptop.

We love our gadgets small, but sometimes it can get ridiculous. You are looking at the world’s smallest cell phone. The Xun Chi 138. It has a 1.3 megapixel camera, a touch screen with hand writing recognition, mp3 player and GPRS capabilities. It weighs just 55grams and measures a tiny 2.64 inches in length. It’s described as a “dual band GSM phone that supports GSM networks in Europe, Australia and parts of Asia, but does not work on North American GSM networks such as Cingular/Cellular One, T-Mobile, Rogers, Fido/Microcell, SunCom, Dobson, Edge Wireless, Alltel, Petrocom, Union, Pegaso/Movistar, Radiomovil/Telcel etc.” As you can see it’s ridiculously tiny, about the same size as a AA battery. Mini-Me would probably dig it, but some of us already have trouble with the buttons on our normal sized phones.

If you’re an outdoors kind of person, but don’t like to carry large gear, such as awkward and long fishing rods, this gadget is for you. It’s the smallest fishing rod in the world. Apparently, it actually has some quality to it. It’s made of stainless steel and polished aluminum. And guys take note, just because you have a small rod, doesn’t mean you can’t reel in a big fish.

They say it can catch a fish up to 4lbs in weight. When it’s all closed up it measures just 8 inches, but will extend to 37inches. It’s small and lightweight, perfect for the Bear Grylls type to quickly catch dinner and continue adventuring. You can store it anywhere. Can hold 120 yds of 5lb line and comes with hooks and everything else you need to get started.

One thing is always true about new devices. They get smaller. Samsung Korea has released the world’s smallest color laser printers, the CLP-315K and CLX-3175FNK. The CLP-315K is equipped with a NO-NOIS print engine that offers a resolution of 2,400 x 600 dpi, 32MB of internal memory, 16 pages per minute(black) and 4 pages per minute in color. This one is 20% smaller than the previous CLP-300 model.

The company also released the CLX-3175FNK laser printer with built-in scanner and fax. It’s 40% smaller than the previous CLX-3160 series. With this printer, you can easily scan documents to USB memory or print documents stored on USB sticks, camera phones and digital cameras without the PC. Until we see something still smaller, these hold the title for now.

I’ve got a bunch of devices that use AA batteries. Said batteries all rotate in and out of the same charger, so something like this would be very convenient for me. Especially if I needed some batteries charged on the go.

It claims to be the smallest and lightest battery charger in the world. I don’t know about that, but I know it will come in handy. It will charge two AA or AAA batteries to 75% of a full charge in three to four hours via the USB port, so it’s not the fastest. For $25, it’s worth it if you have many batteries to be charged.
