Samsung doesn't ship chargers with its phones anymore, not even the flagship phones, so if you don't have a charger you need to buy one separately. The company is more than happy to sell you one but as many of you will be aware, original accessories tend to be expensive.
That's why it's always a great idea to take advantage of any deals and discounts that may be available on official accessories. Samsung's 25W charger is more than enough for all of your Galaxy S23 models, even the ones that support 45W charging, as that one is a bit more expensive.
Buy the Samsung 25W charger from Amazon today for 24% off. It usually costs $34.99 but it can be yours today for just $26.53, with even fast same-day delivery available in select markets.
