Hi, can I use Apple’s 70W charger to charge my iPhone SE (2nd gen) without any issues? I don’t need fast charging, just the convenience of one charger for my 15” MacBook Air (M3) and iPhone SE. I’ll carry two cables: Apple's 60W USB-C to USB-C and USB-C to Lightning, but only one charger.
iPhone SE
Not elaborate, but we'll keep it simple so that you will understand.
The "charger" is actually in the phone, which surprises many users. It controls the amount of current flowing to the battery. It is impossible to overcharge the battery.
You could hook up a 150 W adapter if you want and the battery will charge just fine.
But, the battery won't charge any faster on a 150 W or 70W adapter than it will on a 20W adapter......because the "charger" in the phone controls things.
Now you know.

Now you know.
Any device only “draws” so much power from the power adaptor.
The adaptor doesn’t “force” power into the device.
Another similar example:
A standard electrical wall receptacle can supply roughly 1,800 watts. (15 amps @ 120 volts)
You can plug a 25 watt lamp into it just fine because the light bulb STILL only draws 25 watts.
Does not matter who supplies the power supply or what wattage the power supply might be as long as it is 20W or higher. Stay away from the "no names" though.
Your next question might be what happens if you use a 10W power adapter. The battery will not charge as quickly as a 20W adapter. You can probably guess correctly about how much longer it will take.
It will work just fine and safely.
Sure, no problem
It will apply to any quality, name-brand, MiFi certified power adaptor such as Anker or Belkin.
Cheap, knock-off, and counterfeit adaptors (e.g. sold from gas station counter “grab jars”) shouldn’t be considered for use on ANY device; much less a pricy Apple product.
Some background on MiFi Certification — including the packaging markings to watch for — is provided FYI:

One last question: Can I use Apple's 70W USB-C charger or Anker's 70W dual port USB-C charger (50W + 20W from 2 ports / 60W from one port) to charge my iPad Mini 2 without any issues? I've been using a 12W USB-A charger but want to switch to USB-C. I don't need fast charging. I believe this question differs from my previous one because it involves transitioning from USB-A to USB-C.
Please provide an elaborate answer to help me understand the science behind it.
Thank you, @Bob Timmons & @Chattanoogan!
Is this applicable to multi-port chargers sold by Anker, Spigen, and Belkin, or only those made by Apple?
Chattanoogan has already answered that question for you above.
Does iPhone SE (2nd gen) support Apple's 70W Charger?
