24 hours after using the battery, I am pretty amazed by this device's capability. It's 9600mAh capacity was stunning as it could charge 60% of my iPhone using only 25% of its battery power. Personally, I haven't try it with my iPad, but I am confident that this battery is able to charge my iPad fully. The weight so far isn't much of a problem, but the only thing is that you must charge the battery for about 15 hours to be fully charged. Anyway, I'm pretty contented with the battery's performance and its capabilities, and I strongly recommend this to users with devices that has a weak battery.
