Compact companion

While preparing a multi-day city trip the idea came up as I can "extend" the battery performance of my smartphone. A short research I ended up quite quickly in the Power Bank anchor. The price of just 16 and the capacity i. H. v. 3000mAh were the decisive reasons for purchasing discontinued.
The first positive surprise I got already when opening the package. This had not only noble, but also waited with some from a marketing point of very clever details. For example, there was a small turn card with the headings "Happy" or "Not Happy" in the package, under these were then accordingly support contact details and a link to the parts of the positven experience to find.

But now to the actual product:

Positives:
Delivery are next to the Power Bank, a USB cable and a small carrying case. Everything makes a high quality impression and even after repeated use, I can not tell the rapid wear, as it is found in other low-cost products usually. The Power Bank is very compact and can be as a man in a jacket pocket easily transported without barely noticeable. You can determine whether more capacity is available on a small button. Should this be the case, the control LED lights up for a few seconds. If the Power bank is empty, the LED blinks. Charging works very quickly in both directions, ie, the Power Bank is rapidly recharged for the next use and the charging of smartphones by the Power Bank works without long waits.

Optimization measures:
Concerned to be intense with the Power Bank, one finds some optimization measures. I have deliberately chosen the word "optimization" and decided against terms such as "negative" or "vulnerability". The reason is that these points have the "whining at a high level" come close.
Examples: In addition to the status LED would be a multi-stage charge level indicator (eg LED 5 in 20% increments.) Sensible. Also, the weight can certainly be a bit optimized. Last but not least you have to squeeze the Power Bank with the USB cable into the small bag, because it is still very compact. Here a little more size would not hurt.

Conclusion: product appearance, performance / quality and price are right and I'd buy this power bank at any time.
