On average a camera battery will charge in 1-6 hours, depending on the battery and the charge it will hold. Sometimes, it can depend on where you are charging it also. For more info, refer to your owners manual for your camera, or your battery if it was purchased seperately.
That all depends on which one- way too many variables to answer that question correctly
I have a Casio Exilim Z600 that I purchased in 2006 and love it! It has a base that it charges on and it will keep a charge for a few weeks still and it's 3.5 years later. I used it to take hundreds of pictures and at least 10 videos of my kids every month. My older child loves to re-play the videos on the camera and the charge still stays for that long. The only complaint I have is that the way in which the wrist cord is attached to the camera. It's difficult to explain but mine detached and there is no way to reattach with out sending back to the manufacturer. I asked 2 separate camera shops in town. I would like to add that I have repeatedly dropped this camera and it still works great with multiple dings.
it takes 4.5 hours using the mains and 5 hours using the usb.
The time it takes to charge a kobo will depend on the charging method and the kobo's battery capacity. On average, it can take between 1 to 4 hours to fully charge a kobo device from 0% to 100%. If you are using a fast charger, it may take less time. Check your kobo's user manual for specific charging times.
