The Powerpak Itorch has great form and size. Very easily fits in the palm of your hand. Easy to charge although using USB it will take several hours. The cable is included (USB to micro USB) that allows for easy use. You will need an Apple cable however for specific Apple products. Charges an Iphone very quickly. 50% to 100% in just about 30 minutes. Also works with an ipad just takes about twice the time. Is a significant tool to extend use and very easy to have with you. The laser pointer and flashlight feature are added benefits. Extremely powerful laser so worth keeping handy for presentations. The battery life extension well worth it and great for trips where you have limited access to a power source. Would strongly recommend for the frequent traveler and commuter.
