The small and powerful external battery fits into any handbag and was recognized right from my wife. With 6400 mAh it is sufficient for about 2 full phone charges. The article as a whole is very well made. The two USB outputs with different outputs are suitable for universal and for different types of mobile phones. The brushed aluminum housing flatters in the hand and feels good. The remaining charge status is displayed via 4 LEDs. I find the battery very practical.
