Can you use an iPad charger on a MacBook?
Yes, if the brick is USB-C Power Delivery and the Mac has a USB-C port. The Mac only draws what it needs. Wattage is the real question. Many chargers that ship with an iPad are about 20W. That sits under an Air's minimum, and a long way under a Pro. At idle the battery creeps up. Under load it often stalls.

The short answer
Read the watts printed on the brick, not the word “iPad” on the box. A USB-C PD charger with enough power will charge the Mac. A weak one still charges, slowly, and often cannot keep up while the screen and apps are on.
The wattage table uses these figures. Apple minimums: 30W (13" Air M1 through M5), 35W (15" Air). Fast charge on M2 through M5 Airs: 70W or higher, or Apple's 67W adapter on 13.6-inch models. The M1 Air is not on Apple's fast-charge list. A 14" M5 starts at 60W (70W for M5 Pro/Max). A 16" Intel 2019 starts at 96W USB-C; a 16" from 2021 aims for 140W USB-C. About 20W is under every one of those lines.

About 20W: it charges, it is not a daily Mac brick
The Apple USB-C charger page lists 20W with iPhone and iPad, and treats it as too weak for daily Mac use. Same reading here.
| Situation | What you get |
|---|---|
| iPad brick ~20W, Mac idle | Slow charge |
| Same brick, Mac in use | Often not useful: the battery stalls |
| MacBook Air M1–M5 | 30W (13") / 35W (15"). Fast charge: Air M2 through M5. |
| MacBook Pro 14" / 16" | Pro 14" M5: 60W min, 96W+ fast. Pro 16": 96W (Intel 2019) or 140W USB-C (2021+) |

When it is a stopgap, and when it is not
A stopgap: Mac closed or idle, until you find the charger you actually use.
The iPad's USB-C cable is enough at this rate. The brick is the limit.
A workday on an Air or a Pro: about 20W will not keep the battery ahead of you.
Pro 16": Intel 2019 is 96W USB-C; from 2021, 140W USB-C is recommended (140W minimum on M5 Pro/Max). An iPad brick is not in that band. See the MacBook Pro 16 charger.
MagSafe or USB-C
An iPad charger is a USB-C brick. It does not snap onto MagSafe 3. On a recent Mac, plug it into a USB-C port with a USB-C cable.
MagSafe 3 adds the magnet, the LED, and the high-wattage path on compatible Pros (140W target). It is not mandatory. USB-C Power Delivery charges the Mac once the wattage and the cable are up to it.

Apple or a compatible brick
To replace the iPad brick for daily use, official and compatible both work if they are USB-C Power Delivery and the watts match the Mac. A 20W Apple adapter stays an iPhone / iPad charger. For an Air, aim at 30–70W+ depending on model. For a Pro, step up using the table.
The brand question lives on Apple vs compatible. The listings are in the comparison.
