Your iPhone always decides to die at the most inopportune time, are we right? You need to look up the restaurant directions or send a five-word text just as your phone shows that dreaded flashing voltage sign. With the Incipio offGRID, a mere click will zap your phone back to life like a portable defibrillator. The case saddles right up to your iPhone, leaving little extra bulk and barely any sign of its hidden power inside. The OffGrid charged our dead iPhone up to about 65%, enough to carry us through a precious few hours extra until we could get back to a wall charger.
