Charging Your D90 Camera: A Step-By-Step Guide

The Nikon D90 is a popular camera with a range of features, but it is not without its limitations. One such limitation is its inability to charge via USB. While it may seem convenient to be able to charge the device using a standard USB cable, this is unfortunately not possible. The USB Voltage of 5V is insufficient to charge the camera battery, which requires ~7.4V. As a result, users must rely on alternative methods to ensure their camera is powered and ready for use. This can be achieved through the use of an EH-5a AC Adapter, which can power and charge the camera when access to a wall outlet is available. Additionally, ensuring that the camera is properly set up and configured, as outlined in the user manual, is crucial for optimal performance and battery life.

Charging a Nikon D90 via USB

Unfortunately, the Nikon D90 cannot be charged via USB. The USB cable is only for data transfer and, if left on while plugged into a USB port, will drain the battery.

The Nikon D90 requires a higher voltage than a USB port can provide. The camera does, however, have a DC IN jack on the side, which can be used with an EH-5a AC Adapter to power and charge the camera.

If you are looking for alternative charging methods, you can also use an MB-D80 grip with the camera, which allows you to use AA batteries.

It is recommended to always carry at least two batteries when travelling, to avoid situations where you are left without power.

Using an EH-5a AC Adapter

The Nikon D90 camera does not support charging via USB. However, it does feature a DC IN jack on the side, which can be used to charge the camera using an EH-5a AC Adapter.

The EH-5a AC Adapter is a great solution for charging your Nikon D90 camera when you don't have access to a standard battery charger. Here's a step-by-step guide on how to use the EH-5a AC Adapter to charge your camera:

• Locate the DC IN Jack on Your Camera: The Nikon D90 has a DC IN jack on its side. This is where you will plug in the EH-5a AC Adapter.
• Connect the EH-5a AC Adapter: Ensure that your EH-5a AC Adapter is compatible with your Nikon D90. Then, simply plug the adapter into the DC IN jack on your camera.
• Power Source: The other end of the EH-5a AC Adapter should be plugged into a power source, such as a wall outlet.
• Charging: Once connected, the EH-5a AC Adapter will begin to charge your camera's battery. The charging time may vary, but you will typically have a fully charged camera ready for your next shooting opportunity.
• Remote Locations: Keep in mind that the EH-5a AC Adapter requires access to a power outlet. If you are shooting in a remote location or are constantly on the move, this option may not be as feasible, and you might need to rely on additional batteries or other charging solutions.
• Alternative Options: While the EH-5a AC Adapter is a convenient option, there are also alternative third-party AC adapters available that serve as a replacement for the Nikon EH-5, EH-5a, and EH-5b adapters. These alternatives are often more affordable and can be found on popular online shopping platforms.

The EH-5a AC Adapter provides a reliable way to charge your Nikon D90 camera when a standard charger is not available. By following these simple steps, you can ensure that your camera is charged and ready for your photography needs, especially when you are near a power source.

Battery life and power saving settings

The Nikon D90 is a versatile camera with a range of features that can help you conserve battery life and make the most of your shooting time. Here are some tips and settings to maximize your battery life:

• The Nikon D90 uses a rechargeable lithium-ion EN-EL3e battery, which offers approximately 850 shots per charge (CIPA standard). This provides a good balance between capacity and performance, but heavy usage, especially with video recording and Live View mode, can drain the battery quickly.
• One way to extend battery life is to purchase the MB-D80 battery grip, which allows you to power the camera with either two EN-EL3e batteries or a set of six AA batteries. This not only doubles your battery life but also improves the camera's handling, especially when shooting in portrait orientation.
• When not in use, make sure to turn off the camera to conserve battery power. The D90 has a power switch on the top that allows you to turn it on and off easily.
• The D90's battery charge indicator is quite detailed, so keep an eye on it to monitor your remaining battery life. This will help you plan your shooting and ensure you don't run out of power at a critical moment.
• If you're going to be away from a power source for an extended period, consider bringing a set of fully charged backup batteries. This will give you peace of mind and ensure uninterrupted shooting, especially if you're on a long trip or in a remote location.
• Be mindful of how you use certain features that consume more power, such as Live View and video recording. While these are great tools, they can drain your battery faster, so use them judiciously.
• Another way to conserve battery power is to adjust the auto-off timers in the camera's custom settings. By reducing the time it takes for the camera to automatically turn off when idle, you can extend your battery life, especially during extended photo shoots.
• Finally, when storing your camera for long periods, make sure to charge the battery to around 40% before putting it away. Storing batteries at full charge can reduce their lifespan, so this simple step will help maintain your battery's health over time.
