A:Answer Yes, the Samsung 45W charger is compatible with the Samsung Galaxy A51, but there are some important details to consider:
1. Compatibility
The Galaxy A51 supports 15W Adaptive Fast Charging, which uses the USB Power Delivery (USB PD) 2.0 protocol.
The Samsung 45W charger supports USB PD and PPS (Programmable Power Supply), so it is fully compatible with the A51.
Conclusion: It will charge the A51 without any problems.
2. Charging Speed
Even though the charger is rated for 45W, the Galaxy A51 only supports 15W fast charging.
The phone will limit its power draw to 15W, so you won’t see any faster charging speeds compared to using a standard 15W Samsung charger.
3. Use Case
The 45W charger can still be a good option if you want a universal charger for multiple devices (e.g., a laptop or newer Samsung phones that support 25W or 45W charging).
However, for the A51 alone, it may not be cost-effective since it won’t utilize the full 45W capacity.
4. Cable Requirements
Ensure you use a USB-C to USB-C cable with the charger, which is typically included with the Samsung 45W charger.
Summary
Yes, the Samsung 45W charger works with the Galaxy A51.
The A51 will only charge at 15W, so you won’t get any added benefit from the 45W capability.
For optimal value, consider a more budget-friendly 15W or 18W charger if you’re only using it for the A51.
