Smartphone case with Built-in Charger/Pop-up Crank

When phones tend to lose power they are not of much use and it could happen to anyone especially those that are smaller or older. However a phone case with a spare battery built-in could solve the problem. Usually power cases tend to be bulky and not so attractive but there are some new devices which have been slimmed down while helping to charge up the device.

Smartphones when they tend to be drained off would cause a bit of inconvenience to the user.The creation of a smartphone case with a built-in charger together with pop-up crank could keep the phone powered and in use. The design of the Ampware, putting the case in production is in the pipeline which tends to charge within a minute to keep the smartphone running for extra 40 minutes of talk time.

If an additional five full minutes to crank is done, the user could use the phone for an extra three hours. This is a first run through of hand wrench which has been shaped as a part of a telephone case. Besides this, it also has a USB port wherein one could use the case to charge other devices also and not just the phone to which it has been connected

Charge Phone - Spinning Handle

A smartphone case capable of charging the phone with built-in hand crank has been put up for sale. A wind up iPhone case which could charge a phone by spinning a handle towards the back could solve the problem of battery anxiety. According to the designers the Ampware CrankCase offers three hours of power on winding the handle for only five minutes.

The technology which tends to make the work is not revolutionary but has been incorporated in a solid though possibly life-saving smartphone case. Co-founder of Ampware, Mark Gabriel based in Baton Rouge, Louisiana had stated that he was inspired to develop the device after he had been separated from his family by Hurricane Katrina in 2005. He realised that without power, there was no way where one could stay in touch with friends and family.

With several of the people having the same problem during the incident like Karina as well as the recent happenings during Hurricane Sandy, he had to find a way in order to enable people to stay connected irrespective of access to a traditional power source. According to him `CrankCase tends to leverage the prevailing technology in a new way in generating power, keeping the mobile device charged without the need to depend on the traditional power outlets.

CrankCase – Magnetic Dynamo generator

CrankCase tends to use a magnetic dynamo generator in order to create the power required to charge the phone. It utilises a rare earth metal spinning within a magnetic field in order to generate electrical current in a coil of wire rolled around the magnet. Mr Gabriel had mentioned that spinning the handle on the back of the case for a minute could provide adequate battery life of 40 minutes of standby use for an iPhone and 20 minutes for an iPad mini.

 The handle towards the back of the case could also be utilised as a means of support for propping up the phone while watching videos. Mr Gabriel has now launched a campaign on Indiegogo in order to fund the development of the case and the team intend to start shipping the device at a cost of $59.

To pre-order the Ampware case, an early bird donation of $29 is essential wherein the estimated delivery would be in October this year.
