The best laptop power banks for 2024

Laptop power banks are essential for those who need to work or use their devices while away from outlets. They offer high-capacity batteries that can recharge multiple devices, including laptops. When choosing a laptop power bank, consider its capacity, measured in milliamp-hours (mAh), with 20,000 to 27,000 mAh being ideal for laptops. Higher capacities may not be allowed on airplanes due to TSA regulations. The listed capacity does not reflect the actual charge delivered to devices due to voltage conversion and energy dissipation, leading to an estimated 60% efficiency rate. Look for power banks with multiple USB ports, including USB-C and USB-A, for charging various devices. Some ports offer different wattages, allowing for faster charging of compatible devices. While AC ports are available, they are less efficient than using USB ports directly for laptop charging. Wireless charging capabilities have improved, offering faster charging speeds, especially for Samsung Galaxy phones, although wired connections are still more efficient. Laptop power banks are typically bulky and weigh between 1.5 to 2 pounds, so consider portability. Most have a display to show the remaining charge and features like wireless charging pads and AC ports. Testing involves charging various devices, noting charging time, capacity used, and other factors like portability and design. The guide recommends several laptop power banks, including the Zendure Supertank Pro, Mophie Powerstation Pro XL, Mophie Powerstation Pro AC, Lion Energy Eclipse Mag, Lion Energy Trek, Baseus Blade Laptop, Anker Prime 27,650mAh, and Goal Zero Sherpa 100 AC, based on testing with various devices like iPhones, Galaxy phones, iPads, and MacBook Pros. The guide will be updated as new products are released.
