Hand-powered Windup Mobile Phone Charger

The Hand-powered Windup Mobile Phone Charger is a perfect and affordable little gadget that allows you to top up your mobile phone using nothing but hand power. We’ve seen hand-powered chargers before, but this one stands out as it’s so cheap at just £5.99 (around $10) and it supports a number of mobile phones (sadly not the iPhone though). (more…)

Crank-Power Active Trax Audio Player

The Active Trax Audio Player eco-gadget is an amplifier and FM radio that can charge up using solar power, hand power (via the handle) and good ol’ AC mains power. Using a 3.5mm audio jack, you can play your iPod or any other MP3 music player that has a standard headphone socket. (more…)

Hand Powered Eco Media Player Revolution

If you’re travelling anywhere, one of the most irritating situations is that your music player dies; the batteries have run out of juice. That’s why I like the Eco Media Player Revolution, as you charge it up by hand-power. Refreshingly for a media player, it fully supports major music formats including Apple AAC, Microsoft WMA, MP3, and OGG Vorbis. (more…)

Hand-powered Penguin Torch for the Kids

Sometimes these eco-friendly gadgets do end up being a little odd, however, this is a green gadget focussed firmly on the kids. This is a hand-powered torch in the shape of a penguin. (more…)

Piranha Dynamo and Rechargeable Shaver

It’s refreshing to find a hand-powered green gadget that’s actually useful, particularly with the Piranha Dynamo and Rechargeable Shaver. With just 1 minute of cranking, you get 80 seconds of shaving time. If you charge up the shaver via the mains, it would take 8 hours and give you around 60 minutes of shaving.

However, if you’re in the middle of nowhere, a hand-powered shaver is a pretty useful eco gadget. If the shaver had some kind of generic charging socket, you could use a solar panel too. However, standardised charging sockets are a long way off, but it’s a simple idea that might sell a whole lot more gadgets.

Hand-Powered Mini Dynamo Massager Torch

Hand-powered torches have been around for ages. Essentially you repeatedly squeeze a lever that converts the linear motion into a rotational motion that drives a dynamo. The dynamo then charges an internal battery that allows the low-powered light (often LED-based) to light up for a few minutes or hours. However, the Mini Dynamo Massager Torch, rather bizarrely, adds a massage function! (more…)

Dance Charge – Charge your phone whilst you dance

Orange have announced the release of an eco friendly gadget prototype, a charging device that is powered by movement or “dance energy”. The concept uses a collection of magnets and coils to generate electricity from movement; the same principle used by kinetic watches. The Dance Charge has been designed with summer festival revellers in mind, allowing the device to charge from movement such as dancing. (more…)

Hand-powered Cranking MP3 Player

This intriguing little MP3 player is recharged from either a traditional USB connection or by hand. With just 60 seconds of cranking by hand, you get up to 10 minutes of power to play the music. If you’re in the middle of nowhere without a USB power source, it’s a great way to keep your batteries going and it’s good for the environment too. (more…)
