Can I Use An 18W Charger For A 15W Phone?
You can use an 18W charger for a 15W phone, but it’s essential to consider a few factors before doing so. The main concern is whether your phone can handle the higher power output of the 18W charger. If your phone is designed to support up to 15W charging, it may not be able to take full advantage of the 18W charger’s capabilities.
However, most modern smartphones have built-in charging controllers that regulate the amount of power they receive from the charger. This means that even if you use an 18W charger with a 15W phone, the phone will only draw the amount of power it’s designed to handle, which is 15W in this case. So, in general, using an 18W charger with a 15W phone is safe and won’t cause any damage to your device.
Will Using An 18W Charger Charge My 15W Phone Faster?
Using an 18W charger with a 15W phone may not necessarily charge your phone faster. As mentioned earlier, your phone’s charging controller will regulate the amount of power it receives from the charger, so it will only draw 15W of power even if the charger is capable of delivering 18W.
However, if your phone is capable of fast charging and the 18W charger supports the same fast-charging standard (e.g., QuickCharge, VOOC, or USB Power Delivery), you may still see faster charging speeds compared to using a standard 5W charger. But the difference in charging speed between a 15W and 18W charger will likely be minimal.
Can I Use A 15W Charger For An 18W Phone?
Yes, you can use a 15W charger for an 18W phone, but it may not charge your phone as quickly as an 18W charger would. If your phone is designed to support up to 18W charging, using a 15W charger will limit the charging speed to 15W.
However, using a 15W charger with an 18W phone won’t cause any damage to your device. The phone will simply charge at the lower power output of the 15W charger. If you don’t mind waiting a bit longer for your phone to charge, a 15W charger can still be a viable option.
What Happens If I Use A Charger That’s Too Powerful For My Phone?
