1. DC Cable Drive not only can play the role of adapter, but also can effectively suppress harmonic currents.2. High-quality chips, DC inverter conversion efficiency.3. Good stability, high current output, low static current.4. DC Transmission cable Connection, for digital camera supply, Mobile : 5000-30000 Ma, the equivalent of a number of cameras new battery ; When you turn on the flash to photograph or video, provide uninterrupted . Improves the stability of camera work.Precautionary measures:1. In order to make your camera work best, use high-quality to move the supply, mobile needs to output 5 volts 2/4 current. When the supply or current is insufficient, you can not out, please select at least a better current.2. The mobile supply has automatic hibernation mode and closes.3. Do not use computer USB, because the computer USB 2.0 output voltage is mostly 5v, but current is less than 500mA current.4. Some mobile phone/ USB charger and resistor recognizer, do not recognize the camera, current can not meet the requirements, so it is not recommended.5. Use the camera for a long time, set your camera standby time to the longest standby timeInput: 5 V-2A-4AOutput: 7.4 kvConversion efficiency: 92% (high-efficiency conversion rate)USB Plug Specification: USB2. 0Length: Greater than 150 cmReplace the camera battery handle or carry more batteries, the camera battery handles will be placed overweight, not photographed.BTX Fotocamera/camera Modelli:for Rebel T2ifor Rebel T3ifor Rebel T4ifor Rebel T5ifor 450 550Dfor 450 600Dfor 450 650Dfor 450 700Dfor Kiss X4Colour:ackMaterial:Plastic + MetalPackage Contents:1 x Dummy BatteryOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
