iPhone/iPad question
 

I have three chargers, from left: iPhone 6s, iPhone SE, and iPad. I imagine that I can use one charger for all three instead of sticking to the one that came with the unit. If so, does it matter which I use?

Door #3 will charge the fastest, Monte Hall. I have all three and that's the one I prefer.

Yes you can use the iPad charger across all your devices, and in fact Apple recommends it. The devices themselves will gauge the flow of power into itself. BTW using the iPad charger will charge your phones faster.

You are only limited by cables, if they plug into the charge, you can use it. The largest would be the highest power, so it would work for all three. More power is good, less power is not so good.

no, it doesn't matter. All 3 will do the job

Thanks
 

I am the OP, thanks to all responders, the answer seems obvious.

Your questions have been answered, OP but here is a side note that may help you. The cords that attach to the cube and to your device can fail after a few years of being bent in the same place. If your device fails to charge make sure the electrical outlet it’s plugged into works and then question if the cord has failed

The chargers in general are either 1 or 2 watt capacity .

No. 5 to 12 watts is more typical. 20 watts for newer models.

The newer iPads use a different charging cord. FYI

Sort of. The iPad Airs and iPad Pros use USB-C. The "regular" iPad still uses Lightning. You can always buy a converter.

The three you showed are the cheapies that came with your mobile devices. I almost never use them. They make replacements with higher power and more USB ports. One of these will replace all of them and allow you to charge everything at once using a single outlet. It’s great for travel. I’ve had good luck with them.

It really depends on what is on the end that plugs into the device
 

So the iPad plug has a usb end to plug into the iPad, I am not sure when Apple switched over to the lightening charger I am pretty sure the iPhone SE would have the lightening end and the iPhone 6 might also if it also is a lightening end then you could use the middle one for both phones but not the iPad hope that helps

I don't use any of the three that the OP posted normally. I use the circular pads that you lay your iPhone on and the Ipad is plugged into the Lightning Port on the iMac Mini. The iPhone 13 Pro Max holds a charge for close to two days.
