While on vacation in France, can I charge my USA purchased iPhone using ‘only’ a universal adapter and a USB cord? (No block)
I reviewed the specs on the adapter and compared them to the specs on a ‘block’. They appear to be very similar.
Adapter input: 100-250 volt, 0.3 amp max
Adapter output: 5 volt, 3.1 amp (total)
Block input: 100-240 volt, 0.3 amp
Block output: 5 volt, 2.0 amp, 10.0W
Would it be safe to bypass the ‘block’?
iPhone 8, iOS 15
Those are close enough. It's the output voltage that is most critical and you're OK on that. Lower amp chargers may be slower but that depends upon the draw of the device being charged. If it was rated at 3 amps then using 2 amps will be slower. If it's rated for 2 and you have 3, it will draw 2.

"You can use any of the adapters listed below to charge your iPhone, iPad, Apple Watch, or iPod. You can also use third-party adapters that comply with applicable safety standards."

Any thoughts on this response I received outside of this forum?
My first thought is no. As I understand it, Europe uses household current at 250 volts, single phase and 50 cycles per second. In the USA, that would be 120 volts and 60 cycles per second. The USA phones run on the USB output of +5volts DC.
Another response outside of this forum:
Probably fine.
I would rather take extra though – even if you have to give something away along the way to lighten your load 😊.
Is there no one that can answer this question. So far it’s stumped 2 excellent electricians and no replies in the blog…
