Below is a detailed guide to the chargers that suit each MacBook Air model, followed by tips for selecting the optimal adapter and cable.
Identify Your MacBook Air Model
The 13‑inch MacBook Air (M1 or M2) ships with a 30W or 35W USB‑C charger and can optionally use a 67W USB‑C charger for fast charging. The 15‑inch MacBook Air (M2) comes with a 35W USB‑C charger, with a 70W USB‑C charger available for fast charging.
| Model | Standard Charger (W) | Fast‑Charge Option (W) |
|---|---|---|
| 13‑inch MacBook Air (M1/M2) | 30W (USB‑C) or 35W (USB‑C) | 67W USB‑C (fast charging) |
| 15‑inch MacBook Air (M2) | 35W (USB‑C) | 70W USB‑C (fast charging) |
Standard vs. Fast Charging
Standard charging for the MacBook Air uses the included 30W (13‑inch) or 35W (15‑inch) USB‑C power adapter, delivering a consistent, moderate power level that keeps the battery topped up during everyday tasks and light workloads without stressing the cells.
Fast charging, by contrast, requires a higher‑wattage USB‑C Power Adapter, 67W for the 13‑inch model or 70W for the 15‑inch and a compatible USB‑C to USB‑C cable, allowing the battery to reach roughly 50% capacity in about 30 minutes, which is ideal for quickly replenishing power when you need to resume work or travel with minimal downtime.
Standard Charging
Standard charging uses the charger that ships with your Air, typically a 30W or 35W adapter and provides a steady charge rate that is suitable for everyday use and light workloads.
- Use the charger that ships with your Air (30W or 35W).
- Provides a steady charge rate suitable for everyday use and light workloads.
Fast Charging
Fast charging requires a higher‑wattage USB‑C Power Adapter (67W for the 13‑inch model, 70W for the 15‑inch model) and, when paired with a compatible USB‑C to USB‑C cable, can deliver up to a 50% charge in roughly 30 minutes.
- Requires a higher‑wattage USB‑C Power Adapter (67W for 13‑inch, 70W for 15‑inch).
- Delivers up to 50% charge in roughly 30 minutes when paired with a compatible USB‑C to USB‑C cable.
Can You Use a Higher‑Wattage Adapter?
Yes, you can use a higher‑wattage adapter because Apple devices draw only the power they need, so a 96W or 140W charger will not damage a MacBook Air. The Air will still charge at its maximum supported rate (67W or 70W) and using a higher‑wattage adapter is useful if you own multiple Macs and want a single charger for all.

Recommended Apple Chargers
Apple offers several USB‑C power adapters suited to the MacBook Air. The 30W adapter is ideal for the standard‑power 13‑inch Air, while the 35W model works well with both the 13‑inch and the standard‑power 15‑inch Air.
For faster charging, the 67W adapter can be used with the 13‑inch Air and the 70W adapter with the 15‑inch Air. A 96W adapter supports multi‑device setups and can charge the Air without exceeding its maximum rate and the 140W adapter, designed primarily for the 14‑ and 16‑inch MacBook Pro, can also be used with the Air if desired.
| Charger | Wattage | Ideal Use |
|---|---|---|
| Apple 30W USB‑C Power Adapter | 30W | 13‑inch Air (standard) |
| Apple 35W USB‑C Power Adapter | 35W | 13‑inch or 15‑inch Air (standard) |
| Apple 67W USB‑C Power Adapter | 67W | 13‑inch Air (fast charge) |
| Apple 70W USB‑C Power Adapter | 70W | 15‑inch Air (fast charge) |
| Apple 96W USB‑C Power Adapter | 96W | Multi‑device setup; works but does not exceed Air’s max rate |
| Apple 140W USB‑C Power Adapter | 140W | Primarily for 14‑/16‑inch MacBook Pro; can be used with Air if desired |
Cable Requirements
Use an Apple USB‑C to USB‑C Charge Cable in the 0.5 metre or 1 metre length, which supports up to 100W; for fast charging, choose a cable rated for at least 67W–70W, while longer 2 metre cables are typically limited to 60W and will not provide fast‑charge speeds.
- Use an Apple USB‑C to USB‑C Charge Cable (0.5m or 1m) that supports up to 100W.
- For fast charging, ensure the cable is rated for at least 67W/70W.
- Longer cables (2m) may be limited to 60W; they will not deliver fast‑charge speeds.
Non‑Apple USB‑C Chargers
The charger must support USB‑C Power Delivery (PD) and meet or exceed the required wattage of at least 67W for fast charging. Choose reputable brands such as Campad Electronics that have proper certification, for example USB‑IF compliance. Verify that the cable used can handle the charger’s wattage; otherwise the charge rate will be limited.
- Must support USB‑C Power Delivery (PD) and meet or exceed the required wattage (≥ 67W for fast charge).
- Choose reputable brands such as Campad Electronics with proper certification (e.g., USB‑IF).
- Verify that the cable used can handle the charger’s wattage; otherwise the charge rate will be limited.
Safety and Battery Health
The MacBook Air’s power‑management circuitry prevents over‑charging and limits the current draw, so using a charger with a higher wattage than the laptop requires is safe, the device will only pull the power it needs. However, cheap or uncertified adapters that lack proper voltage regulation should be avoided, as they can cause overheating and accelerate battery degradation.

How to Choose the Right Charger
First, identify whether you have a 13‑inch or 15‑inch MacBook Air. Next, decide if you need the standard charging speed (30W for the 13‑inch, 35W for the 15‑inch) or a faster option (67W or 70W).
Choose a certified charger, either Apple‑branded or a reputable third‑party USB‑PD adapter and be sure the cable you use is rated for at least the same wattage as the adapter. Finally, consider opting for a higher‑wattage charger such as a 96W or 140W unit, which can power multiple Macs and reduce the total number of chargers you need.
- Determine your model: 13‑inch or 15‑inch Air.
- Decide on charging speed: standard (30W/35 W) or fast (67W/70W).
- Select a certified charger: Apple‑branded or reputable third‑party USB‑PD adapter.
- Match the cable: ensure the cable’s wattage rating meets or exceeds the adapter’s output.
- Consider future devices: a 96W or 140W adapter can serve multiple Macs, reducing the number of chargers you need.
FAQs
Can I use a 61W charger?
Yes, but the Air will charge at the lower rate limited by its own circuitry; you won’t get fast‑charge speeds.
Will a 96W charger charge my Macbook Air faster?
No, the Macbook Air caps at its maximum supported rate (67W/70W). The extra capacity is unused.
Is it safe to plug two chargers into a MacBook Air?
The system draws power from the source providing the highest wattage; connecting multiple adapters does not increase charging speed.
Can I charge my iPhone with the Macbook Air’s charger?
Yes. The iPhone negotiates the appropriate current and a 67W/70W adapter will safely charge it.
Do I need a MagSafe charger for the Macbook Air?
No. All current Macbook Air models charge via USB‑C only.
Bottom line
For a 13‑inch MacBook Air, a 30W or 35W USB‑C adapter is sufficient for everyday use, while a 67W adapter (or any higher‑wattage, certified USB‑PD charger) provides fast charging. For the 15‑inch Air, use a 35W standard adapter or a 70W fast‑charge adapter. Always pair the charger with a USB‑C cable rated for the charger’s wattage to achieve the intended charging speed.
In short, selecting the right charger for your MacBook Air or any MacBook, comes down to knowing your model, deciding whether you need standard or fast charging and pairing a certified USB‑C power adapter with a cable that can handle the required wattage. While Apple’s own adapters are always safe, reputable third‑party options work just as well when they meet USB‑PD specifications.
