While portable chargers or power banks are ubiquitous among smartphone users now, there’s a new range of such devices which bring the advantage of wireless charging, a feature trend that is gaining popularity especially in Windows Phones in last 18 months.
These are essentially the portable power packs that you can carry around, but without the need for wires. When you want to charge your phone, you just lay it flat on the brick. While the Nokia Lumia 920, 928, and 1520 (non-AT&T models) can charge natively, the Lumia 720, 820, 925, and 1020 can use optional shells to enable the Qi feature.
Few months back, Nokia introduced DC-50, a $99 wireless portable charger that packs 2400 mAh battery. It was followed by the announcement of a similar product by Hong Kong-based Mugen Power. I’ve been using the Mugenizer N11 portable wireless charger since a few weeks, and it is one of the two chargers, the other being a Nokia DC-18, I carry with me when I head out.
