The iPhone is good at many things but battery life isn’t one of them.
To make matters worse, you can’t swap out the battery.
I carry the power cord around me everywhere when I’m traveling and I’m always plugging in. But that isn’t easy to do. Many coffee shops (also known as my traveling office) don’t have exposed outlets. And sometimes, I get so caught up meeting a founder that I just forget to plug in.
Then my iPhone goes from phone to brick. We’ve all been there and it sucks.
So i recently picked up the Just Mobile Gum Pro battery pack. A fully charged battery pack can charge my iPhone 2-3x times via usb.
I brought it with me on this trip to San Francisco. It’s been a life saver.
