Similarly, it is asked, what should I look for when buying a phone charger?
When buying a battery charger you want to be sure to get one that matches the voltage of the phone. If the voltage is too low, the phone will charge too slowly and may not even be able to reach a full charge. If the voltage is too high, it could ruin the battery and possibly the device.
One may also ask, do higher watt chargers charge faster? Watts, then, are the product of volts and amps — volts (V) times amps (A) equals watts (W). Greater current and higher voltages charge batteries faster, but there's a limit to what they can take.
Similarly, you may ask, how many watts does it take to charge a phone?
Cell phones, mobile phones, even smart phones and tablets are very energy efficient because they are designed to run on a battery for a long period of time. Cell Phones use approximately 2 to 6 watts when charging, while a charger left plugged in without a phone will consume 0.1 to 0.5 of a watt.
Can I use 4.5 V instead of 5v?
Another thing to note: Most digital devices today that run off 5V feed that rail directly into a voltage regulator which drops it to 3.3V or lower. Those devices need the input voltage to be a little higher than the target voltage, so maybe 3.6-3.9V at a minimum. Bottom line, you should be fine with the 4.5V supply.
