I absolutely love the packaging – it’s simple clean lines and appearance just shout “quality”. And there's certainly no disappointment when lifting out the charger with it's soft rubbery surface and curved shape. It's also a good size and not too heavy! So I'd be happy to have it in a pocket if I felt I might need it with me, with my Note II in my other pocket. The charger is about the same width as the Note II, but not as long and slightly thinker.
It so simple to use too. Just a slight shake to wake it and a circular segmented light shows the level of charge, which was near fully charged on arrival. So it didn't take long to complete it's charge using a micro USB cable I already had plugged in for my phone. It comes with a micro USD lead, but not with it's own USB wall plug - which was fine by me as I have plenty anyway.
There are 3 USB sockets, one of which is intelligent so it will charge any device as quick as possible. So plenty of flexibility.
I've not done any charging time tests, but the first time I charged my Nexus 7 tablet was plenty quick enough for me. It probably used up roughly 10 to 15% to fully charge the Nexus 7 from about 30% to fully charged. So the charger still has loads of charge left.
I fully recommend others to buy this product, or other Anker charger, if you want a good quality product. They have a good range of chargers with different capacities depending on your requirements.
I will definitely be looking at Anker products in the future.
Pros: Huge battery charges my phone (Samsung Galaxy S3) from flat to full around 4-5 times on a full charge of the power pack. It charges as fast if not faster than a standard UK Power outlet, and alot faster than the in car charging system I have so I often favour this over the car charger when I'm driving. You can charge upto 3 devices at any one time which has proven very useful when I have been out with friends we just all connect up and throw the phones in a bag while they all charge up. Granted charging multiple devices does share the charging speed thus slowing it down but it is still very quick and effective at charging the devices. I have used with various phones and tablets of various brands including apple product and never had a problem with any of them. Design:- The product is extremely well designed, a little heavy but again to be expected given its capacity. Its about the size of a small 2.5" external portable hard drive perhaps a little bigger but certainly small enough to carry around with the rest of your gear in a backpack. It could even be considered pocket sized if you have large pockets.
Cons: The charge time of the battery pack is very very very long, I would estimate 16-24 hours to charge the pack from flat to full however I have found that this seems to vary but it ideally wants to be charged at least a day before any long trips. This is kind of to be expected however given that the device has a 12000mAh battery and is therefore about 5 times the capacity of most high end smartphones.Read more ›
On the plus side (and it's a big plus) like most of the Anker products I've bought this unit really does deliver the goods, refilling my Samsung tablet once and S4 phone twice on one charge.
Dislikes? Well the short supplied lead would charge other appliances but for some reason couldn't be used to charge the unit itself. The battery meter on top of the unit seems to light up at random with the slightest vibration even not plugged into anything. I'd prefer to see more conventional display of capacity.
Anker seem very responsive to comments and suggestions and genuinely interested in making sure their customers are happy with their purchase. This is a very positive trait ensures that I favour their products precedence when selecting new tech.
