The build quality is very good and the bag for transport (included and with the new models gray and velvety) served its purpose. On the plus side, the charging cable is in the bag also ranked, so need not be carried separately.
Even my first device was unfortunately broken, but at this point I have to praise the outstanding support of anchor. I was part of a new anchor device sent (on Amazon.com) with the request to dispose of the defective device properly. Anker sees itself in dealing with their customers, so I was packing and return it saves and I did not have the items and new order or the like. Excellent, thank you for that.
However, the capacity of 3200mAh can not be fully utilized due to the power loss of 20%. Of the approximately 2560mAh 3200mAh therefore remain, which effectively available. This information can be found under the same FAQ by anchor information here would not have noticed me and therefore desirable.
The loading time is negligible due to the low capacity and depends on the charger used. It should be pointed out the Charger from Anker (Anker® 40W), which also makes me good service.
Although the build quality obviously varies, I would recommend the device still without a guilty conscience because of the customer support of anchor is excellent and problems are solved easily.
