A good thing to have on hand is a power bank (portable charger)! They are cheap and handy. You need to check the mAh (size) and also the weight if you carry it around in your purse. The one I have gives my cell phone three full charges. I can charge three devices at one time. If there is a power outage, it's a must have.
