Is it necessary to buy a powerbank
I have a doubt, do the powerbank can charge the battery plugged in camera? My camera battery can be charged with the PC USB port.
When I view the amazon and find a very interesting cartoon powerbank , the amazon page below
I think it is very useful for me with my bag, but I do not know it can be used as a power supply for camera, it can replace the spare battery?

Power banks are very useful to us; it extended the life of batteries of smart phones, tablets and laptops. All though we have to be very careful in buying power banks, in online there are tons and tons of choice to buy the power banks at affordable rates, when we buy the cheap power bank chargers have to beware the storage capacity of that chargers. A couple of times have to think about the quality of power bank before buying from online.
