If you are running out of power on your iPhone or iPad, the UNU Ultrapak can bring it back up to speed in less than 15 minutes, with up to 75% power. The Ultrapak charges itself faster too, being able to collect energy at record speeds –up to 8X faster than conventional recharging methods. To achieve such charging speeds, Ultra-X deploys a much stronger charging input, rated at 31.25W. This means that within approximately 15 minutes the Ultrapak has stored the equivalent of a full iPhone 5 battery.
The Unu large unit is the Ultrapak Tour ($99.99). It's a 10,000mAh with two charging ports. The smaller one is the Ultrapak Go ($59.99). It has 3,000mAh ultra-portable w/ one charging port. Available late September, 2014.
Leo says that packs a lot of juice and with the capability of charging faster is a definite selling point.
