This review deals with the OXA Power Bank with a capacity of 10,000 mAh. This is nevertheless enough to mathematically almost 4 times fully charge a Samsung Galaxy S4.
My text is complemented by an attached video.
The battery comes in a green packaging and is processed clean and tidy. Apart from the actual Power Bank are still mandatory instructions and various adapter plugs and a gray bag there.
The dimensions are quite acceptable (about 11cm long, 7 cm wide and 2.3 cm deep) for the relatively large capacity. At least you're still first on the weight (220g) puzzled because you do not keep this little box subjectively for so hard. That to me is not a negative point, because the supposedly high weight is mobile batteries in the nature of things.
Charged is the unit eg with the normal smartphone charger. After about 6 hours the battery is fully charged. Big plus compared to the competition is a digital display that provides information on the current energy storage level. There are 2 outputs (1 x 2 A, 1 x 1A), thus 2 devices can be charged simultaneously. Unfortunately, the labeling of the outputs is very difficult to read. My smartphone is charging reliably and in good speed. However, the Power Bank does not reach the specified values of 10,000 mAh. After repeated loading and unloading I guess the actual capacity only to 70% of the declared value.
The manual is in English and not really enlightening. However, one needs for such a product does not necessarily provide an accurate manual, because everything goes more intuitive by equip.
The gray bag I find awful, both in appearance and feel. Sure, that's a matter of taste, but for me this is unfortunately the same land in the trash. The included adapters I can not say much, you can watch the video if there is really something interesting here.
Small gimmick: In the Power Bank a small flashlight is built, the only short distances but provides enough light.
Conclusion: Good Power Bank in a compact housing. Toll is the display with charge status. The stated capacity is apparently not quite reached (there's a star deduction), although the device is more than useful!
