Universal Magnetic Mount 7000mAh External Battery Charger, Portable Travel Charger Power Bank with Built-in Lightning & Micro USB 2-in-1 Cable for iPhone & Android

I keep it in my glove box. You should to.

My phone was 17%. And it took over 6 hrs to charge. I am returning it.

This is great item to have as a back up when your phone gets low on battery life. I love that I brought this charger for a trip, and it's nice being able to consolidate the number of sockets I take up.
