When’s the last time you really needed to get some work done on a flight and tried to plug your laptop into one of those seatback USB ports? Good luck with that — your portable phone charger isn’t going to save you as you watch the laptop’s battery quickly sink into the red.
The Anker Prime Power Bank is the must-have portable charger for this and basically any other tight spot where you absolutely have to have fast, reliable charging for your devices. That’s devices, plural, because the Anker Prime delivers its mindblowing 300W of charging power through three ports and does it without compromise. The only compromise Anker’s making is on the price of the Prime Power Bank — it’s just $171 at Amazon, equalling its lowest price of the year.
Three ports — two USB-C and one USB-A — deliver up to 300W combined, with a single USB-C port capable of 140W output on its own. That’s fast enough to charge an M4 MacBook Pro to 50% in 27 minutes, or an iPhone 16 Pro to 50% in 26 minutes. At 140W, it’s running two MacBook Pros simultaneously at full speed rather than trickle charging while one throttles the other.
Rapid Recharging
Multi-port chargers have been around for a long time, but the Anker Prime might be one of the very first ones with dual input ports. Plug both of the Prime’s USB-C ports into AC outlets and it can go from completely dead to 50% in just 13 minutes, or 40% in only 10 minutes. Even if you’re running behind you can juice up at the gate and have your Anker Prime ready for a long flight.
The Prime’s capacity is 26,250mAh — or 99.75Wh, which sits just under the 100Wh TSA limit for carry-on lithium batteries. That’s intentional, and it means the Prime clears airline regulations without requiring special handling or gate-check anxiety. In practical terms, 99.75Wh charges an M4 MacBook Pro to about 80% from empty, or keeps phones topped up through a full multi-day trip without hunting for outlets.
Easy Reading
Like many of Anker’s high-end portable chargers, the Prime Power Bank has an easy-to-read smart display that shows real-time charging status for the power bank and any connected devices. The Anker app gives you manual control over output power for situations where you want to prioritize one device or limit charge rate on a sensitive device. The 240W USB-C to USB-C cable is included in the box, along with a travel pouch and a 24-month warranty.
For any multi-device home, the Anker Prime Power Bank is a luxury that’s priced well below the luxury line. For work travelers and other road warriors, it’s much more necessity than luxury, and while Amazon’s listing it at a 2026-low $171, it’s a necessity that won’t break your budget.
