The VB99 Mini V Mount battery from K&F Concept is delivered in a very stable box, which is lined with foam on the lid and on the bottom. The manufacturer has included a leaflet with instructions and information, but unfortunately the language is only English. A charging cable is also not included in the scope of delivery. The black plastic housing is very solid and most of the connections are protected from splash water by soft rubber covers. The first thing I did was fully charge the battery. The capacity of the internal lithium-ion battery with a size of 6700 mAh is displayed with percentage accuracy. The OLED display is easy to read, but I would like it to be a bit bigger. The glossy black surface on the front is approx. 65 mm wide and approx. 60 mm high. The display, on the other hand, is only about 20 x 10 mm. The strengths of this device lie in the protective mechanisms such as overcharging, overvoltage or overcurrent. In addition, the internal battery can be charged even though a camera or smartphone, for example, is being supplied with power. I was able to quickly charge my smartphone via the USB-C as well as the USB-A socket. While the charging time via USB-C corresponded to that of my 220 V power supply, it was even a little faster via USB-A. Conclusion: very solid power dispenser with a sharp OLED display, but I would like it to be bigger. I'm not deducting a star because you can see this in the pictures before you buy it. I hope this review is useful
