The 4.2V rating means that the charger is specially designed to charge lithium-ion and lithium-polymer batteries.
These are the most common types of batteries found in modern electronic devices.
The 4.2V rating refers to the maximum voltage that the charger can provide to the battery while charging.
When a Li-ion or Li-poly battery is fully charged, its voltage should be around 4.2V.
However, during the charging process, the voltage gradually increases from the discharged state until it reaches 4.2V.
The 1A rating refers to the charging current,
which is the rate at which the charger delivers energy to the battery.
In this case, the charger for 3.7v battery can provide a maximum current of 1A (1 ampere),
which means that it can charge a 1000mAh battery in about an hour (assuming a charging efficiency of 100%).
