The main influence of current is the speed of charging - in fact, this is not entirely correct. If the electricity is imagined as water, the current corresponds to the size of the water flow. Pengo is here to remind the readers to pay more attention when selecting power banks! Also don't be greedy and cheap, you get what you paid for.Īmpere is the unit of current. However, the output voltage of some power banks on the market will be higher than 5.25V or lower than 4.75V, so it is easy to cause the phone to burn out or cause internal circuit damage. So far, the standard voltage of USB is 5V☐.25V. If you are traveling to a destination different from the US, please remember to carry a converter! However, the socket voltages in China, Europe and other places are all 220V! If you don't pay attention and plug it in directly, it is very likely to burn and damage the appliance for good! Hereby we remind the readers to confirm the socket voltage of the destination before traveling. US sockets are generally 110V, therefore electrical appliances plugs for the US are also designed to match the voltage of 110. ![]() Because if the voltage of power supply terminal and the voltage of the appliance do not match, it may cause the appliance to burn or be damaged! Here, we will not only introduce to you where you’ll find volts in your daily life, but also list the precautions for volts. And if the electricity is imagined as water, the voltage corresponds to the water pressure, in simple terms, it is the power of electricity. It might seem very familiar to us, but we might not know exactly what it means? Let us explain it to you! These three words actually exist in our daily lives. ![]() I believe that everyone is familiar with the words Volt (V), Ampere (A), and Watt (W), from the general socket (110V), but a converter may be used abroad (ie: 220V to 110V), to cables that we carry around (ie: 1A), and mobile phone battery markings (ie: iphone5 3.8V 5.45Whr).
