Descriptions:

1.DC drive cable can not only play the role of power adapter,while also serving to effectively suppress harmonic current noise.
2.High-quality chips,DC-DC converter,high conversion efficiency.
3.Good stability,can output high current,quiescent current is small.
4.DC drive cable connected power bank supply for digital cameras,power bank capacity: 8000-30000mAh,equal to the new battery in the camera's power many times;When you turn on the flash to take pictures or video,to provide uninterrupted power supply.
5.Using a wide range,suitable for all 7.2V-8.4V digital camera and video camera, Support part 9 v digital products

note:
1.In order to make your camera work better,please use a high-quality mobile power, mobile power bank is output guarantee of at 5V 2 AMP to 4 AMP current. When the power is not enough, will not start or can not shoot properly, Please select a larger current of at least 2.4A, DC 3 Amps or more is better.
2. If the mobile power supply has an auto sleep mode, turn it off.
3. Do not use the computer USB supply for the camera,because most computer USB 2.0 output voltage is 5V,But the current is less than 500mA.
4. Some mobile phone / tablet usb charger with identification resistance, can not identify the camera, the current can not meet the requirements, it is not recommended.

Features:

5V usb 电源线 EH-5A 适用于尼康 EP-5A EN-EL14 EP-5F 直流耦合器 - 第 5 张/共 5 张
Some cameras require that the lid of the camera's battery compartment must be closed.After closing the lid, the camera can be turned on. For details, see the Manual illustration.
Use our cable to connect with a DC 5V power source, you will get a power output around DC 8.4V.
 
So all you need to have: our cable, a power bank(DC 5V 2A), and a DC coupler(also called power supply connector or dummy battery/fake battery). Then you compose a long lasting power supply system.
 
Below are some application examples:

Package :
1  x  DC drive cable eh5/eh5a  (4.0mm*1.7mm)

 When you want to long time shooting outside without AC outlet, then you'll feel it's not convenient. Also you can use with a DC 8.4V power bank, but it's not easy to find a DC 8.4V power bank, and it's expensiver.
 
  By the way, we notice a buyer feedback that, use our prodcuts can start his camera, but when shooting, the camera shut down. we'd like to explain here, we provide the the DC coupler and the USB cable adpater only. For this customer's case, proves our products can successfully connect the power, and the cable adapter successfully improves the voltage. But when shooting, the camera shut down, this the power source's problem. Please use a power source at least DC 5V 2.4A, DC 3A is better. To solve this problem, you just need to change a power source.
  If you use a power bank, please choose a high quality power bank, there are too many power bank in the market. A lots of power bank mark the fake output, they do not allow to draw higher current, when you shoot, it's bond to draws higher power than you start the camera, then the power bank stop supplying the power, then the camera shut down. Such as Xiaomi 20000mAh version, it allows Max DC output DC 5.1V 3.6A, The xiaomi 20000mah mobile power bank can also support continuous output.because some mobile power, when the camera sleep, the demand current is less than 100ma, mobile power mistakenly believe that there is no external device, automatic power off output.

     So we provide this solution, with our coupler and customized USB cable built-in intellgent circuit board(improve DC output from 5V to approx 8.7V), you can connect this USB with DC 5V 2A power source. It's easy to find a DC 5V 2A power bank, and DC 5V 2A power bank is much cheaper than a DC 8.4V power bank.
