[adit06]

I just bought the 25w adaptor from Amazon and the product image says energy efficiency and mine says low standby on the side of adaptor so is this an authentic product.

Please help me

Since you purchased this item through Amazon, you will need to resolve the issue through Amazon. If you believe you received an incorrect or inauthentic item, you can either seek product support through your order page or initiate a return.

Well I just want to know if Samsung has officially changed the writing you know...

[CEParsons]

From what I can see on Amazon, the listing associated with the official Samsung store shows the "Low Standby" Text.

I registered the warranty too it also has ul marking on it and gives superfast charging

[CEParsons]

25W is technically considered Super fast charging, though it is not the fastest charging speed available.

Low Standby = newer adapter model
Energy efficiency = older adapter model

they are basically the same thing: when you done charged your phone, you can leave the adapter stick to the wall socket and both adapter will draw as little as 5mA electricity

So it's authentic right cuz I was also able to register it's warranty
