Most portable chargers top out somewhere around 65W and call themselves fast. The Anker Prime Power Bank’s response to that would be something along the lines of “that’s cute,” because its total output checks in at a staggering 300W — enough to charge two MacBook Pros at the same time. This new beast of the Anker lineup is now $260 during a limited-time Amazon deal that carves 21% from its price.
The 300W total output is split across two USB-C ports and one USB-A port, and Anker says it can run two MacBook Pros at full speed simultaneously. The 140W single-port max means that if you’re only charging one device, a MacBook Pro (M4 Pro) goes from zero to 50% in 27 minutes. An iPhone 16 Pro hits 50% in 26 minutes. For a device that lives in a bag and powers everything you travel with, those are the numbers you’re looking for.
What Most Power Banks Get Wrong
The recharge speed on most high-capacity power banks is, frankly, embarrassing. You charge everything else fast, then wait four or five hours to refill the bank itself. Anker fixed this on the Prime. It supports 250W of input power across both USB-C ports simultaneously, making it the fastest-recharging power bank Anker has built. If you’re on a tight turnaround between trips or just plugged in at a hotel for an hour, you’re actually getting heavy-duty capacity back rather than a token top-up.
The Prime Power Bank’s capacity sits at 26,250mAh, which works out to 99.75Wh. That number is deliberate: The TSA limit for lithium batteries without airline approval is 100Wh, and the Prime slips under it by a quarter of a watt-hour.
Expansion Awaits
A smart display on the unit shows real-time charging info for the power bank and the base. The companion app adds manual output power adjustments per port, which is highly useful if you’re charging something finicky alongside a power-hungry laptop and want to control how the wattage gets distributed. The Charging Base powers up to six devices total when the power bank is docked, turning the whole setup into a desktop charging hub when you’re home and a travel powerhouse when you’re not.
This 21% off Amazon deal brings you this: the power bank, charging base, a 3.3-foot 240W USB-C to USB-C cable, a travel pouch, and a 24-month warranty. At $260, this is the power bank for anyone who’s ever needed to charge a laptop, a phone, a tablet, and a camera at the same time from a single device, and needed it to actually work.
