I have a camcorder which can be operated without battery attached but AC/DC power adapter with DC output 5.2 V - 1A.From the internet I understand that PowerBank provide 5 V - 1A output.Assuming that I do a modification of the USB cable jack of the power-bank so it can fit to the camcorder hole where the AC/DC power-adapter jack goes in :with this power-bank as a power supply (not for battery recharging) :will my camcorder runs normally just like when it runs from AC/DC power adapter ?If the camcorder runs - is it safe for my camcorder running from the power-bank as it's power supply ?I also wonder, why my battery camcorder is DC 3.5V - 860 mAh not 5V - 1A just like the DC output from camcorder adapter ?Any kind of respond will be greatly appreciated. Thank you in advanced.
Got to know from the current of power bank and camcorder that the power bank can charge your camcorder .
If the camera's own adapter supplies 5.2V it should run equally well on 5V. The camera has internal circuitry to drop that voltage to the 3.5V level coming from the internal battery. Your second question is partly answered by that as well. As for the difference between 860 and 1, they are different units. 860 mAh is a capacity for work - it will deliver 860 mA for 1 hour or 430 mA for 2hours. My guess is that the camcorder will draw something like 900 mA and run for slightly less than 1 hour. The capability of the adapter to supply 1000mA does not mean that the camera takes that amount. It is good engineering practice to provide a safety factor: the power supply will not run so hot if it is working below its maximum.
