    Device became fully charged easily & quickly using the included USB-C, and it fully recharged my iphone in a short time (although no cord provided for that). Always keep it with me, as I often need to recharge when no electric outlets are accessible. Power blinks & outages no longer prevent me from staying connected. Heavier than expected, but worth its weight in gold. I find Anker products to be superior to other brands. Highly recommend.
