Can SLR cameras be charged with charging treasure?

No, because the usb port of the camera can't be charged (the charging current of the camera battery is greater than the power supply capacity of the interface, so the usb interface of most cameras can't be charged), and the working voltage of most SLR batteries exceeds the output voltage of the charging treasure, so the charging treasure can't be used.

The battery voltage of digital SLR is generally 8.4V, while the output voltage of mobile power supply is 5V, so it cannot be charged. The charging treasure only has a battery life function, which means it is recommended to use a power supply to charge electronic products. If you are afraid that your battery is not enough, you can buy a vertical handle, which will not only make the camera taller, but also expand the battery capacity.

Maintenance method of SLR camera

1. The camera is a precise instrument with complex structure, so pay attention to avoid violent vibration during use, carrying and storage. For cameras that are not used for a long time, in the rainy season, the camera should be separated from the holster. For cameras that use batteries, the batteries should be taken out and stored in a sealed box or plastic bag. Appropriate amount of desiccant should be put in and stored in a low temperature and ventilated place.

2. Bring the camera into a warm room in winter. If the camera is turned on immediately, a layer of tiny water droplets will be generated on the lens surface. The greater the temperature difference, the more water droplets there will be. Only the water droplets of the lens will evaporate naturally, and cannot be baked by the stove or heating, nor can they be wiped.

3. After the camera is used, loosen the spring of the shutter and self-timer, because the spring will affect its mechanical properties due to fatigue. Don't use the motor to take pictures quickly and continuously without special needs, which is not good for the machine and wastes film. Try to take a selfie with a shutter faster than1125 seconds to avoid damaging the spring. When using the selfie, you should tighten the shutter first, and then pull the camera winding.
