Powering Up the Galaxy Tab S11 Ultra with the Right Charger
Samsung has built the Galaxy Tab S11 Ultra to deliver both performance and endurance, and charging speed plays a crucial role in this experience. The company has designed this flagship tablet to support up to 45W wired fast charging, giving users the ability to power up a large battery in a shorter amount of time. This makes it one of the more capable tablets in its segment when it comes to charging technology.
The tablet features a USB-C charging interface and is optimized for high-speed charging through Power Delivery. It can draw a maximum power of 45W when paired with a compatible adapter. Samsung has confirmed that the retail box includes a USB-C cable but does not include the charging adapter. This decision aligns with its broader product strategy to reduce packaging and environmental waste, but it also means users must purchase the correct charger separately to experience the fastest charging speeds.
For the best results, the recommended charger is a 45W USB-C Power Delivery adapter with an output of 15V/3A. While lower-wattage chargers will work, they will not reach the tablet’s peak charging capability. Using the correct adapter can significantly reduce charging time, which is particularly important for a device with a large battery like the Tab S11 Ultra. This allows the tablet to go from a low charge to usable levels much faster, making it more convenient for users who rely on it for work, entertainment, or travel.

The Galaxy Tab S11 Ultra is equipped with an 11,600 mAh battery, which is one of the largest in its category. This large capacity is designed to support high-resolution content, multitasking, and extended usage throughout the day. When connected to a 45W adapter, the tablet can charge from low to around 50 percent in under 40 minutes. A full charge typically takes around an hour and a half, depending on usage and temperature conditions. For users who need a quick boost during busy schedules, this charging speed can be a major advantage.
Wireless charging is not supported on the Galaxy Tab S11 Ultra, making wired charging the only available option. The absence of wireless charging also simplifies power management by focusing on a single, efficient charging standard. The USB-C interface ensures broad compatibility with modern adapters, power banks, and fast-charging accessories. This approach offers a stable and reliable power supply without the slower speeds typically associated with wireless methods.
Samsung has integrated intelligent charging controls to protect the battery over time. These controls regulate heat and voltage during fast charging, helping maintain battery health in the long term. Users can confidently rely on 45W charging without worrying about excessive heat buildup or performance degradation. The system also balances charging speed with energy management to deliver consistent performance even after extended use.
For users in the United States, the key takeaway is the importance of selecting the right charging adapter. Investing in a proper 45W USB-C PD charger ensures the tablet can reach its full potential. Those who use lower-wattage chargers may experience longer charging times, which can limit the device’s convenience. With its fast charging support, large battery, and optimized charging system, the Galaxy Tab S11 Ultra is built to stay powered through demanding tasks. Choosing the correct adapter is the final step in unlocking its full charging capabilities.
