Solar Instinct Solar - how long takes battery charge via USB for totally discharged state?

About 2 hours it is OK.

Have you got USB2 or 3?

In my case more than 5 hours. I have tried with a wall charger, quick charger and USB port of my laptop. Never less than 5 hours. I think it's not normal.

Hello I had that result on USB3 (Dell Latitude)

Yes, that's long. Do you use the original cable that came with your Instinct? Try cleaning the contacts both on the cable, and on the watch.

Could be also wrong cable or bad connection. When connecting watch to cable, try to push little bit and move with connecting from one side to another.

I also have over 2 hours of charging time

The charging time from 5% to 100% was almost 2:45 hours with a non-original cable from ebay. Next time I will try with the original cable.

Weird, brand new out of the box and it took me about 6 hours to charge from 25% to 100%. Do I really need to get a 3rd party cable?
