The best power bank for a Samsung phone is one that matches how fast your phone can charge, has enough capacity for your day, and stays reliable over hundreds of cycles. For many Samsung Galaxy models, that usually means a power bank with USB-C Power Delivery (PD) and PPS (Programmable Power Supply) support, since PPS helps many Samsung phones hit their “Super Fast Charging” speeds more consistently.
If fast charging is the goal, look for a power bank that lists “PD” and specifically “PPS.” A solid target is 25W output (common for Galaxy S/FE/A-series fast charging), while some newer models can benefit from higher-wattage banks. Also check that the bank has a USB-C port that supports both input (for recharging the bank) and output (for charging your phone).
Capacity is measured in mAh. A 10,000mAh power bank is typically the sweet spot for portability and provides roughly 1–2 full phone charges depending on your battery size and real-world conversion losses. A 20,000mAh option is better for travel, longer days, or charging multiple devices, but it’s heavier and often slower to refill.
Useful extras include a clear battery indicator, pass-through charging (when supported), and multiple ports if you carry earbuds or a smartwatch. If you use wireless charging, a magnetic/wireless bank can be convenient, but wired USB-C PD/PPS is usually faster and more efficient for Samsung phones.

For many Samsung Galaxy phones, PPS helps maintain higher “Super Fast Charging” speeds more consistently than standard PD alone. Without PPS, the phone may still fast charge, but often at a lower wattage.
