AVAILABILITY : 0This boombox does it all and likely, more than you think it would. In addition to being a powerful (try that bass!) boombox, this item charges via solar energy (thanks to its panels) and is able to re-distribute that energy to other portable devices to charge them as well. Connectors are provided for cellphones and it can also charge any mini-USB compatible portable products. It also plays MP3 music thanks to its USB and SD slots. And it plays the radio!Memory: SD / SDHC Cards, 2 GB max, USB drives 2 GB maxFormats: MP3FM RadioSpeaker Output: 2WControls: - ON/OFF - Volume - Play/Pause - Previous/Next - Mode Connections: - USB to DC5V port: for powering and charging the internal battery - USB port to play MP3 files - SD Card slot - Charge slot for cellphone and other portable devices - 3.5 mm (RCA) socket for earphone Power Source: Internal battery, Solar panel, USB connectionCharge time: 3.5 hoursUsage Time: 3 hoursInternal battery: Nokia 3.7V Lithium, 1000mahDimensions: 80 x 90 x 200 mm
