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.

If you use “DC drive cable” and Power Bank:
    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.This situation,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.
   Choose a quality power bank, there are too many power banks on the market. There are some mobile power parameters that mark the fake output, they don’t 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. We recommend: such as the Xiaomi 20000mAh version (not Xiaomi 2C ), which allows maximum DC output DC 5.1V 3.6A, or Xiaomi 10000mah Pro, Zmi 10 20000mah, CHOETECH 10400mAh (QC3.0) and other well-known and reliable brand. Recommended USB power port 5V-5.5V current 2.4A and above, 3A is better.
 
    Tips: General digital battery printed above parameters 7.2V / 7.4V labeled battery, it is the camera's minimum operating voltage, these batteries need to use 8.4V charger, full of power, charger 8.4V said no-load voltage, operating voltage and no-load voltage are two different concepts. External power used in the camera, You need to have enough power to supply, the camera is a load,the operating voltage is far lower than the no-load voltage.Therefore, the Camera adapter's no-load voltage is usually between 8V-9V (Note: the multimeter test is no-load voltage).
