#Volts to watts how to#

This is why Pengo is able to charge 3A, 5A devices with our charging cable! If a charging cable can load up to 3A or 5A, it has a wider range of devices that this cable can charge. If the current is large, it will automatically adjust to the current that the mobile phone can charge, but the charging speed is relatively limited by the mobile phone itself, and it will not increase indefinitely.īe aware that when the current required by the electrical device (ie: 3A) and the current that the converter can provide (ie, 3A) are greater than the current that can be applied by the charging cable (ie, 1A), the charging line is likely to be damaged. Most of today's mobile phones have current management chips. Therefore, the larger amperage is to increase the input wattage under the same voltage to increase the charging speed. What really affects the charging speed is actually Watts, and Watt = Volt x Amps. 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. In relation to the base unit of => (amperes), 1 Milliamperes (mA) is equal to 0.001 amperes, while 1 Watts Per Volts (W/V) = 1 amperes.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).
