When considering that nearly everybody carries a smartphone these days – in addition to their keys and wallet – it makes perfect sense why so many designers and manufacturers have been actively designing accessories ranging from speakers and cases to stands and sleeves for the mobile devices. However, the one problem that everybody runs into is also among one of the most difficult to solve: battery life.
Inspired by the need to create a portable, on-the-go power solution for smartphone users that doesn’t involve carrying bulky cases or powerpacks, designers Doug Stokes and Chris Tait of Design on Impulse in the UK recently created what they are calling “The World’s Smallest Phone Charger” – AKA “The Nipper”.
Consisting of two AA batteries and a magnet that reside on a user’s keyring (the batteries are only installed when in use), the 10 gram Nipper is capable of charging smartphones while users are out and about or perhaps most importantly – during an emergency situation.
“The Nipper was primarily designed for emergency use,” explain the designers.
“When all else fails, when all hope is lost – in situations where you desperately need to use your phone but have no access to laptops, electrical sockets, wind turbines or solar panels the Nipper will be there for you.”
The design of the Nipper contains 3 neodynium magnets that are responsible for both making an electrical connection to the circuit board as well as holding the batteries together. According to the designers, the circuit is actually a “boost converter” that converts the power from the batteries into a 5v power supply to charge your phone. For today’s modern smartphones, this means that the batteries can supply an additional 10% battery capacity in 30 minutes, and 20% in just over an hour.
Like so many other hardware developers today, Stokes and Tait turned to 3D printing to make their idea for the World’s Smallest Phone Charger real – and have put the concept on Kickstarter to help it gain some traction; already, the campaign has surpassed their $10K goal by more than $3K and it has three weeks left to go.
“If we’re making small volumes of Nippers, we’ll 3D print the cases out of high quality nylon, but if demand is high and we have to make a full Nipper army we’re going to injection mold the cases out of polypropylene,” says the designers.
“The two halves of the Nipper are connected by either fabric or genuine leather straps. The neodynium are nickel plated on the classic Nippers, and gold plated on the premium Nippers.”
While the concept is certainly impressive, the fact that Tait and Stokes just graduated school together and entered a national design competition to develop The Nipper makes the story all the more impressive.
“One moment we were doing our finals and the next we were in the centre of London, working on a product we’d come up with in our flat which we’d been given support to make into a reality,” said Stokes.
“A lot of people who have just graduated are spending the summer travelling or trying to find a job and move out of home. But being able to go straight from university to working in Somerset House every day, where you’ve got Parliament on one side and St Paul’s on the other, is pretty amazing.”
Considering that the device comes in a number of colors and will likely expand to include multiple strap options, the charger is likely to fit with anybody’s style similar to modern smartphone case designs.
For those interested, a ‘Classic Nipper’ can be purchased starting at just $23 over on Kickstarter.
