As energy prices rise and green credentials come under scrutiny, each step in the energy path is being examined for inefficiency. Andy and Courtney listen to Paul Panepinto from Green Plug on their technology.
Green Plug have developed a digital controller to optimise the conversion of electricity between AC and DC. For the non-engineers, AC (alternative current) is what is in your wall socket and DC (direct current) is what most of your gadgets use. All those power bricks and wall warts are transformers combined with AC to DC converters to change 110 V AC to 12V / 5V DC.
Green Plug has pioneered the use of intercommunicating digital power and load processors to optimise the AC-to-DC power conversion and increase efficiency. It’s an area that has been typically overlooked in power management but Green Plug has reduced the implementation cost to make the inclusion of the technology cost-effective. Over the next few years, it’s likely that this technology will start to appear laptop and phone chargers, so keep an eye out for it.

The SolarCharge is a universal charger for all types of smartphone including 
The KeyCharge has a smaller capacity at 750 mAh and is intended for a quick boost rather than a full recharge. Small enough to fit on a keychain, the KeyCharge only comes with a micro-USB connector and consequently is not suitable for use with iPhones or iPods. Two variants are available to cater for the different positions of the micro-USB connector on smartphones, i.e. side or bottom. As with the SolarCharge, the KeyCharge is recharged via a micro-USB connector, either from a PC or from a mains adaptor.
