Anker Prime 26,250mAh Power Bank (300W) Black The Anker Prime 26,250mAh Power Bank (300W) is a high-output portable charger built for laptop users, remote workers, and content creators who need serious power away from a wall outlet. Its 26,250mAh cell delivers up to 300W combined across three ports, enough to fast-charge two laptops at once. This power bank suits anyone whose daily gear includes a MacBook, phone, and additional accessories that all need power on the same trip. Key Features & Benefits 300W total output: Splits power across two USB-C ports and one USB-A port, so a laptop, phone, and accessory can charge together without waiting in line. 140W single-port fast charging: Charges a MacBook Pro (M4 Pro) to 50% in about 27 minutes, cutting meaningful time off a laptop recharge. 250W dual-port recharging: Refills the power bank itself to 50% in around 13 minutes when plugged into two chargers at once, ideal for short layovers or busy mornings. Real-time smart display: Shows battery percentage plus live input and output power for each port, so users always know exactly how much charge remains. App-based power control: A companion app lets users adjust power distribution across ports and locate the power bank with a sound alert if it goes missing. Technical Specifications Capacity & Power Battery capacity: 26,250mAh (99.75Wh). For instance, this typically provides about 15,200mAh of usable output after normal conversion loss. Total output: 300W max combined across all three ports. USB-C output: Up to 140W per port (5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A, 28V/5A), with both ports able to run at 140W simultaneously. USB-A output: Up to 22.5W, though this drops to around 20W when all three ports charge at once. Charging Behaviour Recharge input: Up to 250W max using both USB-C ports together with 5A cables and a 140W charger. Consequently, a full recharge from empty happens far faster than single-port charging. Single-device limit: 140W max to any one device, since the full 300W only becomes available when multiple devices draw power simultaneously. Safety system: ActiveShield 4.0 monitors temperature roughly 120 times per second to keep charging stable during heavy use. Adaptive power management: PowerIQ 4.0 detects connected devices and shifts power away from low-demand ports toward devices that need it most. Physical Design & Travel Weight: Approximately 599g (21.1 oz / 1.32 lb), built for a backpack rather than a jacket pocket. Display: Built-in colour screen showing charge level, port status, and personalised screensaver options. Connectivity: Bluetooth pairs the power bank with the Anker app for remote monitoring and control. Air travel: The 99.75Wh capacity stays under the common 100Wh airline carry-on threshold, so it typically travels without special approval. Use Cases Will this charge a MacBook Pro? Yes. Both USB-C ports output up to 140W, enough to fast-charge a MacBook Pro to 50% in around 27 minutes. However, actual laptop compatibility depends on the laptop’s own charging cable and power requirements. Can it charge multiple devices at the same time? The two USB-C ports and one USB-A port support simultaneous charging up to 300W combined. Additionally, PowerIQ 4.0 automatically balances power between connected devices based on their needs. Is it allowed on flights? The 99.75Wh capacity falls under the 100Wh limit that most airlines apply to carry-on lithium-ion batteries without special approval. Rules vary by airline, so checking with the specific carrier before travel remains a sensible Internal link: Anker power banks External link: lithium battery airline rules
