Pocket-sized 5,000mAh power banks get you through a few phone charges but they’re useless when your laptop dies duringa full day away from outlets. The Anker 25,000mAh laptop power bank just dropped to a record low of $87 on Amazon for Black Friday, down from its usual $134, and it is the only portable charger you actually need in your bag.
This beast charges laptops at full 100W speed through any of its three USB-C ports while simultaneously topping up your phone and tablet. The 25,000mAh capacity provides enough juice for multiple laptop charges or keeps all your devices running through multi-day trips. Anker built this power bank with retractable cables, airline-approved capacity and enough output to handle demanding devices that smaller power banks can’t touch.
Three 100W USB-C Ports Handle Everything Simultaneously
The triple 100W USB-C configuration means you can fast-charge three laptops simultaneously or mix and match between laptops, tablets, and phones without sacrificing charging speed. Each port delivers the full 100W when used individually, charging a MacBook Pro or Dell XPS at maximum speed. When using multiple ports together, the power bank intelligently distributes output to maintain fast charging across all connected devices. The power bank recognizes device requirements automatically and delivers appropriate wattage through Power Delivery 3.0 protocol.
The 25,000mAh translates into around 90Wh of actual usable power with conversion losses. This capacity is enough to fully charge a 13-inch MacBook Air twice, a 16-inch MacBook Pro once but with power to spare, or an iPhone 17 Pro about five times. The capacity meets the 100Wh airline limit, so you won’t have to check your bag or face airline restrictions when flying.
Anker integrated two USB-C cables into the device which save you from having to carry separate charging cables around in your bag. The first extends to 2.3 feet via a retractable mechanism rated for 20,000 retractions, affording you enough length to charge devices while they sit on a table or in your lap. A secondary cable is 0.98 feet and doubles as a carrying strap, resisting over 20,000 bends without fraying. Integrated cables mean you’ll never leave home without charging cables or have to waste time untangling them from the bottom of your bag.
The power bank charges four devices at once: two through its onboard cables, one more via the USB-C port, and one for older devices through the USB-A port. This makes the power bank ideal for family outings when everyone needs juice or for professionals carrying several working devices. The USB-A port has standard charging speeds, which are sufficient for wireless earbuds, smartwatches, or anything that does not support USB-C.
Recharging the power bank itself, thanks to the 100W input capability, happens incredibly fast: The battery reaches 30% capacity in just 22 minutes when connected to a 100W charger, while a full charge takes roughly 90 minutes. With this fast recharge speed, you’ll be able to top up the power bank during your lunch break or at a quick stop in a coffee shop.
At $87, this Black Friday deal makes the Anker 25,000mAh power bank cost less than many smaller capacity models that can’t even charge a laptop once. You’re getting triple 100W output, integrated retractable cables, airline-approved capacity, and enough juice to handle extended trips or emergency backup situations for nearly 35% off.
