I have received a new shaver from Philips as a warranty replacement.
Unlike its predecessor, it is charged via a USB port with no charger
supplied. However, the instructions say that it requires a 'certified'
charger (or I can buy a splashproof IPX4 charger from Philips). It is
unclear to me how to determine whether a charger unit is certified or
not. I have tried it with an iPhone charger and it works fine - no
excessive heat, full charge attained. Is this sufficient to allow me
to 'self-certify' the charger? Can I assume that any reputable phone
charger will be compatible?

They are probably meaning that if you charge it in a bathroom you need a
charger suitable for use in a bathroom. If you charge it outside a bathroom
then it doesn't need to follow electrical regs for bathroom use.

So if you have a charger that works then use it and it'll be fine, just
don't charge in the bathroom (or if the charging port is wet).

Thanks for responding so quickly. This was my assumption but I wanted
to check there is no need to compare amperages or anything.

1 Amp or greater USB charger

Charging with a USB cable

If your Philips shaver comes with a USB charging cable, we recommend
charging it using an adapter with an output rating of 5 V, ≥ 1 A. For safe
charging in a moist environment (e.g. in a bathroom), only use an IPX4
(splash-proof) adapter.

Mea culpa I think. I missed the significance of the 'greater than or
equal to' symbol and I could not read the writing on the iPhone
charger. I'm sure it could be expressed in simpler terms for a
consumer audience.

Also covering themselves so if you return it as faulty, they can ask if
you used an approved charger and refuse to replace if you did not.

To do that they would need to state what counts as an approved charger.
Who does the approval and approved to what standard?

Just specify that the item needs a charger made by them and quote the
type number.

But they have not done this. The say it can be charged from USB and
you *can* buy an IPX4 charger from Philips *if* you wish. Hence my
question in the first place.

(From the answers, I am assuming if the unit requires 1 amp, any
charger providing more than 1 amp should be okay.)
