Can I charge my phone with lower watt?
No. The power rating of a charger has no bearing on the life of the battery nor the consumption of power by the device. A higher wattage charger only means it can supply up to the specified amount of current, not that it will push that amount of current to the device.
Can I use 45W charger instead of 65W?
You may use 45w charger instead of 65w because they have same tip but might take longer time for device to be full charge .
Can I use a 45W adapter on a 65W laptop?
Yes. Wattage is a measurement of how much power a supply CAN generate, or how much your device DOES consume. The wattage of your power supply is a rating of the maximum power that can be drawn down from it; if your computer requires 45w but your supply can provide 65w, you will be fine.
Can I use a 45W charger instead of 90W?
Yes, you can draw 45W of output power from a 90W power supply if output voltage and polarities of the connectors are the same, as what the rest of the answers indicated. But bear in mind that the Overcurrent protection limit of a 90W power supply is higher than the overcurrent protection limit of a 45W power supply.
Can I use 33w charger for 18W phone?
Yes, it will just charge as fast as the phone is capable of. So if you charge a 18W capable phone using a 30W charger, then the phone will charge at 18W maximum. The phone will not get damaged at all and it’s completely fine.

For charging it would be fine. It wont damage the system but if it needs say 90w then it will pull from the battery instead of the adapter.
Can I use 65W charger instead of 120W?
You can use a 120W power adapter just fine on a device that only needs 65W. As long as the following criteria are met. Voltage is the same, plug size is the same and plug polarity is the same. Then the only difference is it can provide more amps.
Do more watts charge faster?
Wattage is the overall measurement of power that flows through your charger, so a higher cell phone charger wattage means that your device will charge faster.
Is 90w too much for a laptop?
Yes, you can use a 90 watt ac adapter, a.k.a power charger, for your 65 watt-compatible laptop. It will actually charge your battery faster.It will be too powerful and burn right through the port and motherboard eventually, frying your laptop.

Which is better 18W vs 33W charger?
18W charger is better for smartphone battery life. The reason is very simple. The most damaging thing for a smartphone battery is heat. When charing with lower effect the battery will be less heated while charging and this makes the battery last a year or two more.
Can we charge power bank with 33W charger?
