Eton Crank Flashlight & Phone Charger - 2 Pack

Question -If there is no power, will cell phone towers still work?

Typically speaking, most cell towers and switching stations have backup power capabilities, either in the form of generators or batteries. If the blackout lasts a few hours or less, you will likely not lose cell service, although this is HEAVILY dependent on your specific location and provider.

If the blackout lasts for several days, then you can expect cell service to eventually go down, unless providers or emergency responders make special efforts to keep them up and running by providing additional portable power.
