Design could be improved but the build quality and recharging capacity is useful
on 23 February 2014
Pros: I use my phone a lot more than is probably healthy - with data, bluetooth, wifi, calls, watching movies, surfing the internet, satnav, for work and for the long train journeys to and from. My battery rarely lasts a whole day so this is a great solution. It's the first external battery I've found with a built-in neatly-kept cable and it's the same dimensions as my phone which makes it easy to pocket (though it is still the same size as a smart phone so it's hardly tiny). I like Anker products and have an Anker internal battery as well.
Cons: Aside from the size, I think this needs some design evolution.
1) I use my phone with a rubber cover. The microUSB connection is set in a much wider piece than a standard mains or USB charger cable. Although not impossible, you need to take the phone out of the cover to use this and that makes 3 phone-sized objects to find space for. If the connector was smaller, it could all work much neater. I tried this with a coupl e of other phones in cases to the same end.
2) taking my phone out of its rubber case means that it bangs and slips against the hard plastic case of the external battery when the idea is that the phone can neatly sit on top of it when charging. Perhaps some rubber/non-slip surface on one side of this battery would help?
3) When re-charging the battery from a mains charger (through the microUSB port), the connection is VERY loose. I've tried this with a number of chargers to check this wasn't a one-off. It could be a faulty unit but ANY slight nudge when recharging results in the connection being lost - it's nowhere near as snug as when its own microUSB connector is plugged in.
I do like this as an external battery and Anker make some great products. I just don't think this is there yet.
