Will Apple Watch series 4 use the same charger as previous Apple watches?

I have an aftermarket wireless charger for X includes , watch charger.

Been worker fine with Watch 2.

Just upgraded to Watch 4 and same dock won’t charge the new 4.

Altough Apple supplied Watch 2 white charger does charge new 4.

See example Apple Watch Magnetic Charging Cable (1 m) - Apple and scroll down until you can see and expand Compatibility. All series 1-4 are listed as compatible.

The AC power block with USB output port is absolutely common to all devices, limited only by its maximum rated capacity. A high rating 10 or 12 Watt adapter will still charge small devices like Apple Watch, but the lower rated 5W adaptor supplied with the watch will struggle to charge a hungry device like iPad.

I have a 2 and a 4. I have been using the series 4 for over a week and have only used my series 2 charger on a 3rd party stand in nightstand mode. The 4 charger is still in the box. To the naked eye (mine anyway) the profile of each back seems the same. Finally the compatibility list for the apple branded accessory lists series 1-4 as all using the same magnetic charging cable. I think that pretty much covers it.

The chargers may work the same, but they are NOT the [exact] same chargers.

I think the question really gets at do you keep the old – but longer – charger, or do you keep the new one.

I have a Series 1 and a Series 4 Watch. I also have 3x chargers (in different lengths). All are genuine Apple products bought in-store. 2 of them came with the watches. I bought a short 0.3 M for travel, but it has a metal base, and was purchased around the same time the Series 3 launched.

The Series 1 charger is ± 7.91 mm while the Series 4 charger is ± 8.14 mm.

Personally, will the Watches charge on all 3? Yes. However, when selling my Series 1 to a friend, I gave him the Series 1 charger, even though the one that ships with the Series 4 / newer Watches is shorter.

Definitely., The concavity of the Series 4 charger changed. It’s slightly deeper. Charging works with previous chargers, but it’s not a 100% fit, not the same curve

Yes, the previous chargers work with the Apple Watch Series 4.

The charger interface for all Apple Watches is identical from the original Apple Watch through to the latest Series 4. The part number and SKU have never changed, your Apple charging accessories will be 100% compatible. If you have a third party device like a charging stand you should check with the third party manufacturer, just in case the small change is case dimension (about 1.5mm) is significant.

Well, since none of us here are Apple employees there’s no way for us to confirm anything. I am sitting here with both the original series 0 charger and a brand new series 4 charger in my grubby hands. I can personally confirm that the dimple on the series 4 charger seems to be ever so slightly deeper than the series 0 charger. I can also personally confirm that both chargers work on both my old series 0 watch and my new series 4 watch.

Yes. The original Apple Charging Station works.

I just purchased a series 4 as a replacement for my “Original” and I can assure you that the “Original” charger works just fine with the Series 4.

Yes it will. I had i watch 2 & got iwatch 4. It works

That’s exactly what happened to me with the original series charger. Since I changed to the charger that came with the series 4 (my previous post) it’s charged perfectly every time. I had only used the original charger because I had it in a stand and was lazy and didn’t want to mess with it. I was also told by the sales person it would work fine. So even though the part number remains the same, it seems older chargers may not always work. This is just my findings, your mileage may differ.

The series 4 charger seems to be slightly different than the series 3 chargers. They both charge but the dished recess on the old chargers doesn’t match the new watch profiles. Can anyone confirm?

I can confirm there is some slightly difference between the cables. I have been using the Apple Watch Edition cable since my first watch, series 2, 3 , but now, with Apple Watch 4 it seems there is some kind of inconsistency and incompatibility. It is very common the charge stops without reason. In the beginning I thought it was badly placed, but now I'm sure is the case. I noticed a message at the watch screen saying my cable was not proper for the watch. I called Apple Brazil they told me to buy another cable.

Yes! It is!
