Is it okay to use 15W charger for my phone which requires 25W

I use Samsung A06 5G. My original charger is 25W and EP-TA800. That charger's adapter is not working so I am using old charger which I used for my old phone.

That charger is 15W with model EP-TA200. I purchased that from a local shop last year for my older phone. My concern is that whether that would damage my phone or not. I am being very cautious. Please tell me if there are any side effects of using 15W charger for 25W phone. I do not care about charging speed.

This is the old charger 15W which I am now using.

This is the USB of that 15W charger. It is written VOOC PE here. Not sure if it is authentic or not.

Here is the original charger of 25W for my phone whose adapter is now damaged.

Your Galaxy smartphone supports up to 25W fast charging, but using a 15W charger means it can’t reach its maximum speed.

It’s safe — Samsung devices automatically regulate charging power to match the charger’s capability.

The only downside is longer charging times (about 30–40% slower).

In fact, slower charging can be slightly better for battery health in the long term, since less heat is generated.

If you want speed, use a Samsung 25W PD charger with a good USB-C to C cable. If you’re okay with patience, keep using your 15W one.

Dear Samsung Member,

Greetings from Samsung Customer Support!

We would like to inform you that when you use the 25-watt charging adapter with your device, it will take less time to fully charge compared to the 15-watt charger.

Using a charger with lower wattage will not harm your device's battery. While it might take a bit longer to fully charge, rest assured that it's completely safe.

If you have any further questions, please feel free to reach out.

Warm Regards,
