Needs a bit more power

Zebronics Power Grid 7200MAH
Price: Rs 2,490

We decided to test the Zebronics Power Grid on a busy reporting assignment to Bangalore. The Zebronics Power Grid has a 7200mAh battery and has two outputs of 1000mAh and 2100mAh. To put this in perspective, the Samsung Galaxy S3 has a 2100mAh battery, while the iPhone 4 has a 1400mAh battery. Technically, once in full power, the Power Grid should be able to charge both these devices twice over. The Power Grid has an arc of LEDs which blink when you are charging and glow solid when it is fully charged. The latter is achieved only with six hours of charging, not that easy when you are constantly on the move. So on Day 1, with an early morning flight to catch, we were not able to fully charge the batteries of this box. By afternoon, the iPhone was in the red trying to catch networks on the move and find us the way using Google Maps. Plugged on to the 2100 mAh slot of the device, we were back to full charge in about an hour, just in time for the last meeting. But this had drained the power Grid almost fully.

Next day, the Power Grid's help had to be sought only by sundown. We plugged in the iPhone and an iPad, and both had about full charge at the end of an hour. We would have expected the Power Grid to have at least a third of its charge left by the end of this, but it was fully drained out by its efforts. This is a handy device, but falls a bit short of what you would expect a 7200mAh battery to do.

BAG IT OR JUNK IT? Good for those with multiple devices
