The powerbank model for Motorola 2 is the wireless series powerbank. You can charge the smartwatch til 5 times and also more. In this way you can use your smartwatch for the full week. There are necessary few hours to charge your powerbank, one time is discharged (you can see it from first green flashing led). We choosed Panasonic batteries since they represent the best compromise in long lasting and efficiency. The charging cycle is classic and not fast; this because the batteries can have the better and longer life, and also to avoid fast charging system with smartwatches that cannot support this system. The powerbank can be put either vertically and horizontally, during charging, without any problem, since it locks the smartwatch in a safe way. During charging you can put the powerbank where you want, in your bag, suitcase, backpack,handbag, luggage. Since it is ultraportable, it will charge your smartphone without problem.. There are 4 leds that indicates the charging percentage, from zero to 100% in 4 steps (so 25/50/75/100%). The additional usb port lets you to charge your smartphone when you need, til 3 times, it depends on model. Since we start our production, there will be available a series of different designs to choose from. And if you have a metal strap that cames with your smartphone, don't worry! We have our adjusting screw that can fix perfectly your metal strap like a leather one. For all these characteristics, our powerbank it is a really very useful instruments that can match perfectly your smartwatch, and that says to you: impossible to stay without it! Our powerbank is not a project or an idea. It is the result of three years of hard work, day by day, and it is a real and fully functional product, whose you see the real final prototypes images, not 3d! When in production, obviously they will be again more perfect in details. All our powerbanks, in these three years have never given problems to the same smartwatches and never will give.
