The Cellz Power Case for the iPhone 5 looks great in white. It is a case, a battery pack and it still allows for syncing too. It currently costs £17.49 with free shipping to the UK.

Obviously using a case with a built in battery is going to add considerably to the weight and size of the iPhone. The case weighs 166 grams. The additional battery however is a decent 2,202mAh.

In the box is a leaflet with the instructions, a micro USB cable and the power case itself. The inside of the case is lined with a soft material to prevent any scratching. The top of the case removes to allow you to insert your iPhone. On the rear of the case are 4 LED lights that allow you to track its battery level. Turning off the power case is as simple as holding the power button for 2 seconds. The case does feature 1,000 mAh fast charge in case you’re in a rush.

The case itself is curved to feels comfortable in the hand but you do notice the weight. But I must admit I don’t mind the extra bulk versus the additional longevity of the battery run time.

However, the bulk and weight might put some people off, but for long journeys or if you are a power user this really is an essential item.

But some of the downsides of the case are an inaccessible headphone jack. You would need some sort of extension (not included) or you will have to use Bluetooth headphones. Also, I found removing the iPhone from the case quite tricky as you have to slide it up to remove and there was no logical place to grip from. Also, the plastic removal top piece seems flimsy and I wonder if over time this will break.

So in many ways this case solves a problem, but in another way it does create issues like additional weight.

Rating 7/10.

Is this case for you?
