Smartphones these days, with their dual-core processors will barely last you for about a day, if you rely heavily on 3G. What we need in times like these, is a portable battery and Genius may just have the answer to this with their new ECO-U200 universal power pack. This portable battery pack is available for $39 (Rs.2,067) and a one-year warranty.

The battery packs in a rechargeable Li-ion battery with a 2600mAh capacity. The gadget consists of a microUSB port for connecting any USB-based device. There’s a button to start and stop charging as well as four LED lights to show how much charge is left in the power pack. The output power is 5V, so it will easily be able to charge most smartphones without breaking a sweat. Tablets may be a bit of a challenge though, as they usually require more power. According to Genius, the U200 should offer up to 9hrs of Internet time, 260hrs of standby time and up to 40hrs of audio playback, although these numbers will vary depending on the device being used.
