Besides a big-battery mobile phone itself, Ulefone Power can also serve as the power bank of other devices. In a latest official test by Ulefone, the Power charged iPhone 6 from 2% to 47% in 95 minutes.
During the test, Ulefone Power drained from 100% to 20%, which means 1210mAh of the energy were consumed, given that the Sony li-polymer battery packed in the Ulefone device has a total capacity of 6050mAh. Since the iPhone 6 battery is 1810mAh, we can get a conversion rate of 67%. This is an acceptable figure because after all Ulefone Power is not a devoted power bank and both devices were turned on during the OTG charging. About the OTG output of Ulefone Power, Ulefone says it’s 5V/0.5A.
Ulefone Power is now sold for USD179.99 at Gearbest and Banggood, featuring MTK6753 Octa-core 64-bit chipset, 5.5-inch 1080P AUO LTPS display, 3GB RAM, Sony IMX214 13MP Camera and soon-to-come Android 6.0. In addition, Ulefone Power will come with an OTG cable.
