You can be sure that you are getting high quality E620 Battery Charger for your Canon E620, because all of our Canon E620 Batteries and Battery Chargers are precision-engineered and rigorously tested for voltage, capacity, compatibility and safety to exceed original equipment manufacturer specifications.
What is the nominal voltage and current of Canon E620 Battery Charger mean?
The nominal voltage of Canon E620 Battery Charger power supply normally refers to the open circuit output voltage, that is a voltage value not take any load and without current output. Therefore, this can be considered as the output voltage limit of Canon E620 Adapter. For the internal use of the initiative power supply unit or voltage regulator components of the benchmark, in general the use of high resistance DC voltmeter can directly measured the nominal voltage, even if the mains voltage fluctuations in a certain place, the output is also a constant value;
The current of Canon E620 Battery Charger: Regardless of any Canon E620 Battery Charger has a certain amount of resistance, so when the Battery Charger output current, the voltage drop in the internally , which is equal to the output current multiplied by the Canon E620 power adapter resistance. Resulted in two things, one is the heat generated is equal to the square of the output current multiplied by resistance, so the power will be hot.
Purchasing OEM Canon E620 Battery Charger vs. 3rd Party Battery Charger
