Concord Keystone ECO Booster 2.0 portable battery pack
Owning a whole lot of portable devices these days is the norm for many of us, and if there is one bane of modern electronics, it would be battery power. Or rather, the lack of it. Concord Keystone knows this, and hence decides to step forward and offer something that will definitely appeal to frequent travelers – the Concord Keystone ECO Booster 2.0 portable battery pack. This is an extremely slim and lightweight 2,000 mAh Li-Polymer portable battery pack which will cater for smartphones such as those from the Android and iOS front, more or less doubling battery life in the process when plugged in.
At the moment, the Keystone ECO Booster 2.0 can be said to be the only portable battery pack which features a built-in retractable microUSB charging cable. That is great, as it translates to carrying around one less cable, and will also help save space in your luggage whenever you travel. All you need to do is pull out the retractable microUSB cable when your device needs charging, and a blue LED indicator will light up to inform you that charging is taking place. Apart from that, it will also show off the remaining power level in the battery pack. Measuring a mere 0.4″ in terms of thickness and tipping the scales at 2.5 oz, it is the perfect traveling companion.
