The average replacement cycle for smartphones is 1.3 years. Millions of batteries are lying in people's desk drawers, often with significant charge capacity in the smartphone battery.
South Korea based Enlighten has created a portable smartphone charging solution. The Better Re has been designed to "quench the battery thirst of mobile devices" and to utilise batteries that still have potentially useful life.
The power dock has a "multi-clip" designed to fit any smartphone battery. It uses these batteries to charge your mobile device, tablet camera or iPod. Expansion packs, magnetically attached to the charger give more capacity.
Even after two years of usage, the company claims that lithium-ion cells in smartphone batteries have around 80 percent of their efficiency remaining.
The company aims to "save and create a sustainable energy solution with the sleeping energy" contained within these batteries.
The Better Re charger works with any size or model of smartphone batteries.
It can be used for a long time by replacing the batteries in the Better Re device.
An LED on the device indicates whether the device can be used as a charging device or not.
A micro USB charges both the device and the battery it contains.
There is also an adaptor for devices with 8-pin lightening cables.
Better Re claims that its device has "infinite lifespan and expandable capacity". Its Kickstarter campaign has already received over $42,000 towards its goal of $50,000.
It just could be the solution to your eco-challenges of recycling all of your smartphone batteries and provide you with a seemingly unlimited battery charger for all of your devices on the go.
