Welcome to Blackview (Well-known brand of rugged phones) blog. Hope the guide helps.

Yes, you can safely use a 66W charger to charge your 33W phone. Here's what you need to know:

Why it's safe:

Phones regulate power draw: Your phone has built-in circuitry that limits the amount of power it accepts, regardless of the charger's wattage. It will only draw the 33W it needs, even if the charger offers more.
Higher wattage doesn't harm batteries: Using a higher wattage charger won't damage your phone's battery. In fact, many modern phones support various fast charging protocols, and using a compatible charger won't stress the battery.

What to expect:

Slower charging: Your phone will charge at its maximum supported speed, which in this case is 33W. Even though the charger is capable of 66W, your phone won't utilize the extra power.
No harm, no benefit: Using a 66W charger won't harm your phone, but it also won't charge it any faster than its designed limit.

Additional considerations:

Charger compatibility: Ensure the charger uses a certified charging standard like USB-C Power Delivery (PD) and is compatible with your phone's specific fast charging protocol (e.g., Qualcomm Quick Charge).
Cable quality: Use a high-quality cable that supports the required wattage for optimal performance and safety.
Heat generation: While unlikely, using a higher wattage charger might generate slightly more heat during charging. This is normal and shouldn't be a concern.

In summary

It's perfectly safe to use a 66W charger for your 33W phone. However, your phone will only charge at its maximum supported speed of 33W. Consider using a 33W charger for efficiency and potentially lower cost. If you prioritize fast charging for other devices you own, a 66W charger can be a versatile option.
