It's a shame that I don't feel secure in not getting a fake when ordering Apple accessories from Amazon. Has anyone had any issues with Amazon and fake apple products?

Community Reviews

Apple's 40W Dynamic Power Adapter is a compact travel charger that can burst to 60W before tapering to about 40W as it warms up. That makes it appealing for newer devices, especially MacBooks and fast phone charging, with reports of very quick charging on an iPhone 17 Pro and 17 Pro Max. It is also described as staying relatively cool during use. The main caveats are its larger size than small phone chargers, its limited advantage over cheaper 30W options for phones, and concern about counterfeit Apple accessories when buying from Amazon.

  • The adapter can deliver up to 60W but dynamically tapers toward about 40W as it warms up.

  • The charger can renegotiate lower output power when its surface temperature exceeds a limit.

  • An open-box unit reportedly looked new and charged an iPhone 17 Pro quickly without noticeable heating.

    FeistySnow8629

  • The adapter reportedly charges a 17 Pro Max very fast and impresses with charging speed.

    FabulousMitten373

  • Ordering Apple accessories from Amazon can raise counterfeit concerns that make the purchase feel insecure.

    DCM67

  • The adapter may not support USB PD PPS, so it may not charge phones faster or cooler than other 60W chargers.

    violentleaf

  • The adapter may not be worth it for phone charging compared with cheaper 30W chargers.

    Peichen

  • The adapter's travel-style form factor can be larger than expected for some buyers.

This is Apple's "40W Dynamic Power Adapter with 60W Max', so OP should probably fix the title. It is a 60W capable charger but will slowly taper down to add low as 40W as it warms up. Third party testing shows that this takes about 18 minutes:

This looks like a good deal on a newer, highly compact charger from a highly reputable company.

Most USB-C chargers have multiple voltage modes, but this one renegotiates lower output power as the surface temperature gets above some limit.

Temperature of the charger? Seems like an odd design. I guess they are going for maximum compactness.

You can think of it like temporarily overclocking a CPU for burst performance.

I bought one of these open box off of Amazon. Looks new to me. I am very impressed by the charger. Iphone 17 pro charges fast and does not heat up. It also works well on a Pixel 10 for a relatively fast charge and the phone seems to be cooler than a normal fast charge. I have no temp measurements so this is all anecdotal.

Why not get a real 60w charger?

As long as it sold and shipped by Walmart you should have no issues. Best Buy seems pretty reliable too.

Not worth it over $8~15 30W charger from reputable brands for charging phones as those are way smaller. Only good if you have a MacBook that you want to charge at 60W burst then 40W constant and then charge your phone. For higher power laptop or charging 2 devices together, still have to use 67~100W charger that's also this price range
