With two output ports, you can charge two devices at the same time, and as they deliver voltages of 1.5A and 2A, charging will be faster than the original wall chargers (typically 1A) .
The build quality is good: the shell is simple and solid black plastic, the design is simple. Four LEDs provide information about the battery charge status.
Its compact size allows it to take around with you, but because of its weight of 240 grams, we prefer to carry in a bag than to have it in his pocket. Friendly Note: The battery comes with a small protective cover.
The current price of 39.99 seems a little high, despite the product's actual qualities: less a star.
