I never leave the house without this little black box

When it comes to packing your purse for a night out, most people think of taking the essentials: the cell phone, wallet, maybe a tube of lipstick.

But for me, there's one item I never leave the house without and that's my portable phone charger.

I'll admit it. I'm addicted to my portable phone charger.

I first discovered the glory of this brilliant invention in 2012 during Hurricane Sandy. I was in college in Washington, D.C. and became paranoid by all of the reports of possible power outages for days. I'm a self-proclaimed nervous Nellie and it doesn't take much to get me to worry, but the thought of not being able to use my phone while my family was in New York instantly convinced me to take the plunge and purchase a Mophie.

The storm passed, but that charger started to come everywhere with me. I had a sense of comfort in knowing that I never had to worry about my phone dying again while I was out.

To use the portable charger, you simply charge it with a cable when you're not using it. Then when you take it out, all you do is plug in your phone charging cable, press a button and your phone gets juiced.

I still have my first Mophie and it continues to work five years later, although it doesn't give as much of a charge. I also have another one from Amazon that's slightly thinner and gives your phone a little bit more battery power. When I first got it, I was able to even get two full charges out of one use.
