Top critical review
Great idea, but unreliable in the cold
on 5 March 2014
Having read through numerous reviews of different products, this seemed to be the best choice for an iphone 4 backup/charger.
First impressions were excellent - the item feels substantial and well made, and nice touches like a useful protective bag being included, numerous connectors (less as noted in many other reviews a lightening connector) all for under £20 seems like amazing value for money.
The first few uses were problem free, and helped keep my phone charged whilst off the beaten track and that was more than worth the purchase price.
The problems started not long after purchase, when travelling in sub zero weather in the UK. When plugging in the phone it would charge for a couple of seconds, then stop for a couple of seconds then start again and keep repeating that cycle. The phone was not at fault and I worried that damage could be caused by the stop/start charging. I tried a number of options including new cables etc but without luck. Though I could not be absolutely certain I put the fault down to the very cold weather, but I was no longer confident to still use this routinely.
Anker customer service responded unprompted to my review and replaced the unit - this time with a slightly different model to the one I had bought, including being packed with different accessories. As at Mar 2015 I see that the photo of the item has been changed to a third design, so it seems Anker are changing the product quite often; hopefully later purchasers will have more luck with theirs.
In summary, this is a great idea but did not prove reliable in cold conditions.
