If the battery life of Onick NB-800L 4G image transmission version multi-function handheld high-definition infrared laser night vision device is weak, you can consider the following solutions:

1. Use an external power supply

Power bank: Carrying a large-capacity power bank is a more convenient method. There are many options for the capacity of the power bank, such as 10000mAh, 20000mAh, etc. You can connect the digital night vision camera to the power bank through a suitable USB cable and charge the device when the battery is low, so that the device can be used for a longer time in the wild or other places without a power socket. However, it should be noted that some night vision cameras may have requirements for the output voltage and current of the power bank, and you need to check the device manual to choose a matching power bank.

Car power supply: If you use the digital night vision camera in a place where the vehicle can reach, such as driving a car during a wild adventure, or in a security patrol car, you can use the car power supply to charge it. The output voltage of the general car power supply is 12V or 24V, and you need to use a car power adapter to convert it to a voltage and current suitable for charging the night vision camera to ensure safety and normal charging.

2. Replace the battery

Backup battery: For digital night vision devices with replaceable batteries, it is a good idea to prepare multiple backup batteries. For example, if the device uses common AA batteries (No. 5 batteries) or 18650 lithium batteries, you can buy and carry enough backup batteries in advance. AA batteries are relatively cheap and easy to obtain, and 18650 lithium batteries have a large capacity. The capacity of 18650 batteries of different brands is generally between 2000 and 3500mAh, and you can choose according to your needs. When the original battery is exhausted, quickly replacing the backup battery allows the device to continue working.

Upgrade the battery: If the original battery capacity of the device is small, you can consider replacing it with a battery of the same type with a larger capacity. However, you need to ensure that the size, voltage, interface, etc. of the new battery are compatible with the device and the quality is reliable. For example, some users will replace the original low-capacity lithium battery in the digital device with a high-capacity lithium battery, but this requires careful operation to avoid damage to the device or safety issues.

3. Optimize device use

Adjust the frequency of function use: Reduce the use of high-energy consumption functions. For example, the infrared fill light is a relatively power-consuming function. If there is a certain amount of ambient light, the brightness of the infrared fill light can be appropriately reduced or the usage time can be reduced. When you don't need to record, try to only use the photo function, because the video function usually consumes more power. In addition, avoid unnecessary zoom operations, especially high-magnification electronic zoom, because this will also increase the power consumption of the device.

Reduce device power consumption settings: Check the device's settings menu. Some digital night vision devices may have energy-saving mode or screen brightness adjustment functions. After turning on the energy-saving mode, the device may reduce the performance of the processor, reduce the screen refresh rate, or automatically adjust the power of some functions to save power. Appropriately reducing the screen brightness can also effectively reduce battery consumption, because the screen is one of the main power-consuming components of the device.
