I needed a charge right away. Loved that this charger was ready to go from the package. Gave me enough charge to get home.
Driving my truck I realized that my cell was almost dead because my only on hand USB cable had failed from old age and my rough treatment. I needed to respond and contact people quickly and hated the idea of a quick stop somewhere for an overpriced, chintzy, light duty, knock off of some sort, USB replacement available only in yellow or neon green. Fortunately Sears was close and still open, with a helpful associate who pointed out that for less money a USB cable only, this backup battery included a decent length USB cable and battery was precharged so instead of having to run back out to plug into my truck, I just connected battery to phone walked to food court and completed all work and family tasks while enjoying a wonderful dinner. Carry this with me everywhere, just in case. Highly recommend.
