Your iPhone may have a great battery life but it does not last forever. You are going to need its cable to attach it to your computer or a power source. I don’t know about you but I always end up forgetting to take my iPhone cables with me when I travel. If you happen to have the same issue, you may want to check out the Bluelounge Kii charger. This compact charger is lightweight and lets you charge and sync your iPhone and other Lightning devices on the go.
Kii is small and fits directly on your keychain, as you can see in the above pictures. It is dual-sided, one end is an Apple connector while the other one is a USB so you can attach your phone to your computer. The above pictures show the Lightning version but a 30-pin version is available too. Kii costs as high as $39.95, depending on the version you pick.
