While many electronics that can connect to a computer's USB port can also draw power from that port, the Nikon D90's battery uses a higher voltage than a USB connection can provide. It's thus necessary to charge the D90 using separate charging equipment.
- Skill level:
Things you need
- EN-EL3e battery charger (included with Nikon D90s, or purchase from link in "Resources" section)
Turn off the camera. Open the battery chamber cover on the bottom of the camera by pushing in the tab and lifting the cover. Slide out the battery.
Plug the battery charger into a wall socket.
Slide the battery into the charger and watch for the "CHARGE" light to illuminate and start blinking. A full charge will take about 2 1/4 hours.
Remove the battery when the "CHARGE" light has stopped blinking. Slide the battery back into the camera's battery chamber, with the curved side facing outward, and close the cover.
