Genius now has a new small portable speaker called SP i170 has a spherical design and a range of 8 hours. The SP i170 is a speaker designed to provide sound where we can not be connected to the mains, its design is simple and has an internal lithium battery that, according to Genius gives a range of up to 8 hours.
Since it is a portable speaker, its use is intended primarily to grab for example the beach or hiking. It has a 3.5mm input jack that you can use an mp3 player, mobile phone or other compatible music source. The battery charge is via a miniUSB to USB connector, but would have been interesting to incorporate a microUSB connector on the issue of improving the compatibility with mobile phones.
