Q: I wanted to buy a power bank for my 6s, here in India, via amazon.in . I dont know which brand to trust and go for. Please help!

Hi

When buying electronic accessories for your iPhone, ensure that they are either genuine Apple products or that they have been certified as Made for iPhone under the MFi program. Certified items come with the "Made for iPhone" logo on them and/or on their packaging.

Genuine Apple Lightning to USB cables have certain text and a serial number printed on them.

Using uncertified or counterfeit accessories may damage your iPhone and/or adversely affect operation. Apple's warranty does not cover damage caused by use with a third party product that does not meet Apple's specifications.

Using counterfeit or uncertified third-party cables, for example, can cause issues including:

• Your iPhone may not charge properly.
• Your iPhone may not sync properly.
• Your iPhone could become damaged.
• The cable may become more easily damaged.

The only Brand I recognise is Anker

I have several of their accessories and including a power bank seen as a reputable brand in UK
