Travel Adapter

Depends where you brought from, most Samsung products are made in Vietnam so I would question if you obtained any from China. It's always best to buy from Samsung direct or leading network retailers and not any from the blackmarket it may be cheaper and very risky 😬

Looks like the same thing as the black one you posted about.
On first look. It doesn’t look genuine. Pins look a bit odd to me in your photos. The label looks not quite right.
The packaging or the retailer you got it from will be a clue to how genuine it is.
I will have a look at mine later as mine is definitely genuine

What charging speeds or time are you getting from it?

Personally if I don't know, I will just get the genuine stuff off the Samsung website

It does not look quite right to me for the reasons already mentioned, also the ones I have from Samsung feature a Safety Mark.

Hey there

It sounds like you are looking for a bargain and save some pennies on a charger but having had 99p chargers in years gone by I would always buy either from a well known reputable retailer or Samsung itself.

Why? A dodgy charger can (in a worst case scenario) catch fire or damage your home electrics. And it can damage your device.

Don't risk it is my advice 👌
