    Powerful and Practical Battery case
  

*by M***C on Reviewed in the United Kingdom on 7 January 2018*

A very smart looking functional battery case for iphone 6/7/8. The case provides 3000mAh of charging capacity.The cover features a soft rubber grip to prevent slipping even with with hands. The case weighs 93grams so doesn't add a huge amount of weight, the bulk of the case is also reasonable (adding around 6mm) given it will significantly increase charging capacity to your phone.The case features all the button templates / cutouts you need to access your phone, features a power button recessed into the rear of the battery case with LEDs indicating current level of available charge. The cover goes on easily enough providing snug and protective fit all around the phone, removing is slightly trickier requiring levering from the top but with practice its easy enough. The only slight issue with the case is it doesn't support direct plugging in of lightening port headphones (iPhone 7/8) so will have to resort to using wireless headphones. The single charging connector can used to simultaneously charge both the phone battery and the battery case.Overall a good compromise of power versus bulkiness providing a lifesaver on days when you hammer your phone. Great price for a well designed battery case which you will be glad you have.

    When i first got it it was fantastic, looked good
  

*by C***G on Reviewed in the United Kingdom on 30 December 2017*

When i first got it it was fantastic, looked good, and i never had to worry about going flat, but alas only lasted a month before not working at all, so back to square 1 and wil purchase a different make and model.

    I’m really disappointed I brought this yesterday
  

*by M***L on Reviewed in the United Kingdom on 3 March 2018*

I’m really disappointed I brought this yesterday, the item it doesn’t charge my phone when charging, I have to take the case off and it also doesn’t let me listen to music through my headphones, when the case is attached to my iPhone 7 not sure why it has a circular hole for aux jack, when the item specifically says for iPhone 7s and 8s really really disappointing.
