In California where preemptive power shutoffs are occurring, neighbors help each other keep CPAPs and other medical devices running, reports Peninsula Press.

One of their biggest information needs is how to obtain backup power. For the residents with medical devices, COPE members have been researching the viability of lead-acid batteries, like those used to jump-start cars, and lithium batteries like those used for camping, to power their machines for brief periods. The batteries are better for the environment than gas generators, and cost between $50 to a few hundred dollars, instead of thousands.
