Is it safe to use a 60W charger for a 20W phone? - Croma Unboxed (2024)

Who carries a charger while visiting a friend’s or relative’s place for a night out? No one, right? Of course, they have always got our back. While it’s the most common practice to borrow their chargers when your phone’s battery is running low, the question is how safe is it to use?

Fear not, because it’s absolutely safe to charge your 20W phone with a 60W charger. However, there are some important factors to consider to ensure that your phone remains in good condition. Let’s explore the safety and potential implications of using a different charger for your phone.

Does a higher wattage charger affect the battery life of the phone?

Let’s address the most common concern while using a higher-wattage charger for a lower-powered device. The good news is, in most cases, it won’t. Smartphones are designed with in-built safeguards to manage the charging process. If a charger’s power rating worries you, let’s spill the beans – a charger’s power rating has no relation to your phone’s battery lifespan.

This is because electricity is not pushed by chargers inside a mobile battery. Instead, it is the smartphone that pulls out the current from the charger, and it will draw only the power it needs. This implies your 20W phone will still charge at its optimal rate, and the excess wattage of the charger won’t decrease the battery’s lifespan.

Does a higher-wattage charger ensure fast charging?

If you are tempted by the idea of plugging into a 60W charger to charge your phone faster, sorry in advance! That’s not going to happen. You cannot take advantage of that extra 40W to charge your phone quickly. This is because the phone circuitry will pull only the current it requires to charge the battery.

But here’s some good news for you. If you have a 20W fast charger to charge your 20W phone or a 30W fast charger to charge your 30W phone, you will be able to fast charge your phone, at least as fast as the phone itself supports.

Is it safe to use higher/lower wattage chargers?

Using a higher-wattage charger is safe for your phone, as explained earlier. However, it’s essential to ensure precaution while applying the opposite scenario, i.e., using a lower-wattage charger. A lower-wattage charger may not provide enough power to charge your phone properly. While it won’t harm your phone, it might take much longer to get a full charge. In some scenarios, if your phone supports fast charging and you have plugged into a lower-wattage charger, some batteries may even refuse to charge.

Can a higher voltage charger damage your phone?

While a higher-wattage charger is safe, voltage compatibility plays an important role in influencing your phone’s health. While most smartphones operate on a standard voltage of 5 volts, using a charger with higher voltage can significantly damage your phone. It’s always recommended to use a charger that provides the correct voltage that your smartphone supports. You can check the voltage as it is typically indicated on the charger body itself.

Now that you have all the facts in place go and charge your phone stress-free, considering these above factors.
