A great device that maintains various tablets and phones recharged (while freeing up USB ports of my computer!). This wall charger can charge up to four devices at once via the USB ports on different amps: the two upper ports provide fast charging 5V / 2.4A; the bottom two are 5V / 1A. It is compatible with smartphones, digital cameras, tablets, mp3 and mp4, my Kindle, an LED lamp, even the food banks. The voltage delivered by each USB port is very stable. The end of charge cut preserves battery life. The speed is much faster than most home chargers, too. It works seamlessly with all that I connected on him. It is essential to me to charge a digital voice recorder that had stopped charging by the computer. Finally, the price is very reasonable.
