You are going to need a cable or adapter to charge your iPhone or Android device. It is so easy to forget to take them with you though. ComboZip may help you avoid that. This is a bracelet that can also serve as a charging cable for iPhone and Android devices. This multi-functional bracelet can be extended if you unzip it. It can also help with moving files between your devices.
ComboZip looks decent and is very portable. When you are done with it, just zip it back, and put it in your bag, around your wrist, or anywhere else you can think of. ComboZip is available in Lightning and Micro USB models. The Micro USB model lets you copy your videos, pictures, and documents from your PC/Mac easily.
This interesting product is on Kickstarter right now. You can get an Apple version for under $25 at this time.[via]
