In need of keeping your phone and tablet topped up while you're away from home? How about this whopper from RAVPower, available from Amazon UK for one day only at £16.49. The battery pack comes with a substantial 16750mAh capacity with a pair of 2.1A USB outputs. That'll be enough to charge your phone four times.

Despite its capacity it's still a fairly portable battery pack with a neat power level meter and, as ever, an included flashlight. It comes in either white or black and as it's a deal of the day the price will go back up real soon.

Grab it while it's hot!
