Which charger for Samsung Galaxy A?

For the Galaxy A16, A17 4G, A17 5G, A18 4G, A26 5G, and A27 5G models, you need a 25 W charger supporting USB PD PPS technology. For the Galaxy A36 5G, A37 5G, A56 5G, and A57 5G, a 45 W PPS power adapter will work best. If you want to buy a single charger for the whole family, a 45 W PPS model will easily handle each of these phones at its maximum speed.

The PPS protocol and 5 A cable in everyday use

Samsung uses the USB Power Delivery charging standard with the PPS (Programmable Power Supply) protocol in its smartphones. This allows the phone to constantly communicate with the charger and precisely regulate voltage and current. Without the PPS protocol, on a standard USB PD charger, Samsung smartphones charge more slowly because the adapter cannot adjust its parameters to match the battery's requirements.

For 45 W fast charging, the cable is also crucial. The Galaxy A36 5G and Galaxy A56 5G draw 45 W at around 10 V and 4.5 A. To reach full power, they require a PPS charger supplying around 5 A and a suitable 5 A USB-C cable, as a standard 3 A cable will limit the charging speed.

Fun fact: GSMArena measurements showed that the Galaxy A57 reaches 45 W using a regular 3 A cable and a 3 A PPS charger. The phone charges at a higher voltage reaching around 15-16 V rather than 10 V and 4.5 A like the A56, making the newer model much less picky about cable specifications.

Fun fact: According to specifications on Samsung's websites, the Galaxy A57 charges at the same 45 W power as the more expensive Galaxy S26+. At the same time, the base Galaxy S26 supports charging at only 25 W.

Why a more powerful charger will not speed up phone charging

If you connect a phone that supports 25 W to a 45 W or 100 W charger, the charging time will not decrease at all. The phone itself controls the process and decides how much power it draws from the outlet. The charger will deliver only as much power as the device's internal electronics permit.

A more powerful charger will not damage your phone, as built-in protections ensure proper operating parameters. Buying a higher-power adapter makes sense when you also plan to charge a laptop with it or want to power multiple devices at the same time from a single wall brick.

When selecting chargers for our roundup, we focused on models that fully meet the power standards required by Samsung phones. They will work well both with a single smartphone and when powering an entire household setup of electronics.

Recommended chargers for Samsung Galaxy A

Original or a proven third-party replacement for Samsung

An original charger is a safe choice, but it is not the only option on the market. A high-quality third-party replacement will offer the exact same charging speed as an official power adapter. The key requirement is the presence of the appropriate fast charging protocol specified in the parameter table.

When choosing a third-party charger, make sure it supports the USB PD standard with PPS technology. For 25 W models, look for Super Fast Charging support, and for 45 W models, Super Fast Charging 2.0. The right specifications on the adapter ensure that the phone will utilize its full potential.

Questions and answers about charging the Galaxy A series

Which charger for Samsung Galaxy A?

The choice depends on the specific model from the Galaxy A series. For phones such as Galaxy A16, A17, A18, A26, or A27, a 25 W charger with USB PD PPS support is sufficient. For Galaxy A36, A37, A56, and A57 models, a 45 W adapter with PPS is required, and a universal 45 W PPS charging brick will handle all of these devices properly.

How many watts is a charger for Samsung Galaxy A?

Phones in this series support different power levels depending on the generation and price tier. Galaxy XCover7 charges at up to 15 W, the Galaxy A16 to A27 series draws up to 25 W, while models from A36 to A57 accept up to 45 W. Since the manufacturer does not include a charger in the box, the actual power output depends on which adapter you purchase.

Will a 45 W charger damage a Galaxy A with 25 W charging?

No, a 45 W charger is completely safe for a phone designed for 25 W charging. The device will draw only as much power from the charger as intended by the smartphone manufacturer. The adapter's extra power capacity will simply remain unused, and the battery will be charged at a safe speed.

Do you need a 5 A cable for Galaxy A56?

Yes, if you want to achieve the maximum power of 45 W on the Galaxy A56 5G, you must use a USB-C cable that supports 5 A current. This smartphone charges at approximately 10 V and 4.5 A, which a standard 3 A cable cannot handle. Using a lower-spec cable will result in slower charging speeds.

Does Samsung include a charger with Galaxy A?

No, there is no wall charger included in the packaging of Galaxy A series smartphones. Along with the phone, the box contains only a factory USB-C cable. An appropriate wall adapter must be purchased separately.
