Xperia Z Ultra 4000mAh Mugen Power Battery Case is a bit heavy due to its larger size and the battery plate embedded in its lower portion. As when it charges Xperia Z Ultra, it gets somewhat heated due to induction from the case.

Charging Results

• It took us around 5-6 hours to charge the case fully with the AC Adapter came with our Xperia Z1.
• While charging Xperia Z Ultra from 0-53% , the case got discharged completely and it took around 2 hours 50 minutes to do that.

Well we have used so many battery case till now for Xperia Z, Xperia Z1 and all gives similar results due to lower output power given by case to phone..

Pros

• Durable, easy to use.
• Can charge your Xperia Z Ultra upto 50-60%.

Cons

• Too expensive, many cheaper case are available in market.
• Too much time taken to charge the case.

Mugen Power is well-recognized brand when it comes for external battery case, so it’s purely users wish to got with cheap cases or with a brand, well after using so many case Mugen Power case heats a bit less as compared to others and fits well.
