With lush 13,000 mAh Power Bank it has in comparison to many other models very high capacity. They can thus deliver more power and must be recharged for less frequent but then correspondingly longer than Power Banks with less capacity. Over the longer charging time as well as the higher weight, you should be aware before buying, ie who only occasionally go wants to charge a device such as smart phone, tablet, etc., may not need such a powerful model, but would also well served with a lighter version to 5,000 mAh. That one should think as I said in advance based on the planned use.
The processing of the device leaves no wish unfulfilled. Well, I think first of all that two devices can be charged simultaneously. Primarily outdoor lovers will appreciate the illuminated battery level indicator, as on the built-in flashlight. Also Design-technically, the Power Bank can be proud with its brushed aluminum surface. Overall, the laboratory equipment in my view, therefore, and makes being no notable weaknesses.
