I am a businessman, I am a busy person, I fly everywhere to hold business meeting and attend business activities. Such a series of busy things makes me do need a portable charger to keep my iPhone 5S fully charged during my business trip. As a businessman, I have so many business affairs to communicate with my client, family and friends via my iPhone. Sometimes when I feel tired, I can take a break and enjoy listening to music on the plane. I am a travel lover. I like to use my iPhone to take beautiful photos to record my happiness, sadness, inspiration, interest and unforgettable memory. But unfortunately, almost all smart devices' battery can't maintain for a long-time use, obviously include my iPhone 5S. I'll be crazy if my 5S is power off while I am outside and having an important business talk or travelling. Just like a general who would be panic if his army has no weapons in the war. So, I realized the importance of iPhone portable charger after several lessons on battery died. Busy business life makes me have little time to buy a suitable charger in the supermarket, so I surf the Internet to figure out what kind of portable charger I should choose. But the search result confuses me a lot. There are so many kinds of charger with different capacity, color, weight, design, quality and price.
