Running out of juice should be nearly impossible if you have one of these around. Especially the 20,000mAh power bank from Urbn. 20,000mAh, Let’s put that number into perspective. 20,000mAh can charge an average smartphone more than six times over with some juice to spare. That means long road trips with extensive sat-nav usage should be a breeze. Lying at the core of this powerehouse is a high capacity lithium polymer battery that should provide the same level of power charge after charge. It also features two ports for simultaneously charging two devices, which it does pretty quickly with its 2.1 amp output capacity. It might just be a power bank, but this one has some smarts to go along with the power, intelligently adjusting the power output to safely charge your precious devices. All this in a class leading size and oh so reasonable price. What’s more, Urbn also has a 10,000 mAh variant for the less power hungry folks out there. You can grab the 10,000 mAh variant for ₹899 and the max powered 20,000 mAh variant for ₹1599.
