Most power banks charge one device at a time and slow down significantly when a second device is added. This Anker Prime charger does the opposite: it delivers 300W of total output across three ports whcih is enough to run two MacBook Pros at full charging speed simultaneously while keeping a third device connected. Amazon currently has it at $171, down from its regular $229, a 25% cut on one of the most capable portable power banks available at any price.
300W output, 140W single-port fast charging, and a full recharge in under 30 minutes
The single USB-C1 port delivers up to 140W on its own which charges a MacBook Pro M4 Pro from zero to 50% in 27 minutes and an iPhone 16 Pro to 50% in 26 minutes. Those numbers match or beat most wall adapters that ship with premium laptops, from a device that fits in a bag. When all three ports are in use simultaneously, the 300W total output distributes power without throttling any individual connection, which means two MacBook Pros and an iPhone can all charge at meaningful speeds at the same time rather than sharing a trickle.
The recharge speed is where the Anker Prime charger genuinely stands apart from the competition. The 250W dual USB-C input, which Anker describes as an industry first, brings the bank from zero to 50% in 13 minutes and to 40% in just 10 minutes. That turnaround is fast enough to be useful during an airport layover, a short break between meetings, or a morning where you forgot to charge it overnight. A full charge takes significantly less time than comparable banks, which typically require several hours from a standard 65W input.
The 26,250mAh capacity sits at 99.75Wh, which is just below the 100Wh TSA limit for carry-on batteries, so it flies without any documentation or airline approval process. The smart display shows remaining battery percentage and detailed charging information for each port, and the Anker app allows manual adjustment of output power distribution if you want to prioritize one device over another. The included 240W USB-C to USB-C cable handles the full output without requiring a separately purchased high-spec cable.
The UGREEN Nexode 25,000mAh 145W power bank we covered earlier costs $69 and is an excellent value for most people. The Anker Prime charger at $171 is for a different use case: anyone who regularly travels with multiple laptops, needs the fastest possible recharge time on the bank itself, or wants TSA-approved capacity at 300W total output. With over 1,000 reviews at 4.7 stars and more than 3,000 units sold last month on a product at this price point, the early reception is unusually strong. If two MacBook Pros need to stay charged simultaneously and a wall outlet is not an option, this is the power bank that handles it.
