    After searching for a powerbank that is about 3000-5000mAh, I finally happily settled down with Besiter Mercury 5000mAh. It has a sleek design (glossy on both surface, aluminium feel on the side). It’s slightly smaller than the size of iPhone 6/6s, but it’s thicker than the phone, as shown in picture. I am amazed that the powerbank is charged using lightning cable (which they claimed to be the first to have this). As you can see in the picture, there are only two ports, i.e. lightning and USB. An MFi certified lightning cable is supplied with the powerbank, it’s about 1.5ft long. There are four small light indicators at one corner representing how much battery you left in the powerbank. The indicator looks really neat as it’s white in colour and small (unlike those led indicators which can be too bright). Seller told me there will be one year warranty. We just need to contact them. Amazon order as a proof of purchase. Note: you might have to get some screen protector like protection on your own if you want to protect both glossy surface, but bear in mind these surface have curved edges like the iPhone 6/6s.

    This item arrived very quickly, good to look at and charged my iPhone very quickly, will be invaluable when I am travelling for my iPod iPad mini and iPhone. I will be recommending this to my son who travels worldwide for his work, will be great when he has long haul flights, might get for his birthday in April. I had a question about the product and it was very quickly answered by vender. Having tried out for a few days am pleased at the speed it charges my Apple items, and of course it will be great for my Kindle e-reader with the correct cable. It is also good to look at.

    I have an Iphone and with using it alot during the day, this is extremely useful as I can charge my phone on the move. It comes with a lightening adapter for the iphone, so I didnt need to carry any other cables. Also, it matches my iphone perfectly, defintately looks v. professional.

    My second besiter charger and the better of the two. The smaller size of the mercury and the fact it doesn’t require you to carry a second cable make it the one to have.
    It still has the same solid feel as the eclipse although the 4 lights indicating charge aren’t as good, I preferred a numeric battery life indicator.
    Product arrived quickly and well packaged.
    Overall very satisfied.

    Very reassuring and slim enough to have this in your handbag. Charges my iPhone 5 and iPad 2 with plenty of spare capacity. Great for long train and aircraft journeys. Will suit any future device too by using own device leads too. Takes a few hours to charge the besiter Mercury itself once depleted but this can be done whilst using it too.

    I bought this specifically because it’s supposed to have a pass through functionality to allow you to charge both the bank and your device at the same time. Well, it doesn’t work. I’m really disappointed.

    Only needed it once thus far but worked perfectly. Thin but large – nearer the size of iPhone 6 plus. Not really to carry in a pocket.
