What is good is that this Ismart technology allows the battery to send the maximum power that can receive your devices. If you have a reading light and a smartphone, one can receive 1A (kindle) while the smartphone or the tablet can be up to 2.4. It is really good as it means that your devices are recharged faster than an ordinary battery that delivers only 1A or 2A maximum gold on ordinary batteries, often, choose a single port sometimes I have two devices that want only a low output power (exple: two reading lights !!).
