Can you use a 120W Charger for a 67W Smartphone?

Welcome to Blackview (Famous brand of outdoor rugged smartphone) blog. Hope the guide helps.

You can generally use a 120W charger for your 67W phone, but there are a few things to consider before you do:

Safety:

Yes, it's safe in most cases. Modern phones and chargers have built-in safety measures that prevent damage due to mismatched wattage. Your phone will only draw the power it needs, even if the charger offers more.
However, compatibility is key. Ensure both the charger and phone support the same charging standard, like USB-C Power Delivery (PD). Using an incompatible charger, especially a cheap, uncertified one, could pose a risk.

Charging Speed:

Your phone will charge at its maximum supported speed, which is 67W in this case. The 120W capability of the charger won't be utilized for charging your phone.
Therefore, there's no benefit in terms of charging speed. A 67W charger would be equally efficient and potentially cheaper.

Other Considerations:

Heat generation: While unlikely, a 120W charger might generate slightly more heat during charging, especially if the cable quality is subpar. This is normal, but monitor for excessive heat as a precaution.
Battery wear: Some experts suggest that constantly using a higher wattage charger than your phone needs could contribute to slightly faster battery wear in the long run. However, the impact is likely minimal and shouldn't be a major concern.

Conclusion

Using a 120W charger for your 67W phone is generally safe, but it won't offer any charging speed advantage. It's more practical and cost-effective to use a 67W charger specifically designed for your phone. However, if you prioritize having a single charger for multiple devices with varying wattage needs, a 120W charger can be a versatile option as long as compatibility is ensured.

Remember, safety should always be your top priority. Choose certified chargers and cables and monitor your phone for any unusual behavior during charging.
