There seems to be a lot of innovation happening in the tech industry when it comes to batteries and it looks like 2015 is gearing up to be a breakthrough year in transforming the way we power our handheld devices like smartphones and mobiles.
One of the big players in this area is eZelleron, a startup company based in Dresden, Germany, which has been developing "low-emission energy sources for mobile power suppliers" over the last six years.
Its latest product is kraftweRk, a pocket-sized and very portable power generator that can be carried about in an effortless way. It's unique selling point, the team behind it argues, is that unlike a traditional charger, it "generates electricity rather than merely storing it".
The company says that it is "amazingly small and highly efficient", does not need to be connected to the grid to be charged – uses gas – and operates using new and pioneering fuel cell technology".
"kraftwerk is a fuel cell power generator. Based on our unique and award winning microtubular metallic fuel cell technology, kraftwerk directly transforms gas into electricity," eZelleron states on its Kickstarter page.
"The user fills the gas into an integrated tank. Whenever power is needed, the gas goes into the fuel cell and is converted directly into electricity. A standard 5 V USB plug allows you to connect all your electronic devices supported by the USB standard."
Here are some interesting stats about why it may be a game changer – one filling of the device can supply you with energy that is equivalent to 11 iPhone charges, you can refill it within three seconds and takes most types of gas.
