SpareOne, designed to be an ultimate safety and communication device, provides up to 15 years of battery life when stored unused (off, with plastictab inserted) or 10 hours of talk time when in use.
Flip the tab onto its belly and you'll come face-to-face with the grippy, hard plastic that plays host to an extraneous bit of Lenovo branding and the slate's 5-megapixel camera module.
