The high-capacity Anker Prime Power Bank 26K 300W is getting a significant discount, falling to $179.99 for eligible shoppers with a $50 price cut from its list price of $229.99.
It’s a deal of the day, good for today only and available exclusively to Prime members — and easily one of the best deals on a top-tier portable charger we’ve seen so far this season.
What distinguishes this model is just how much brawn it packs into a travel-friendly corpus. If you’ve been holding out for a superhighway of power that charges your laptop quickly and has room to juice up all your other soon-to-die gadgets — without weighing down your bag — this one is in just that lane.
Small but mighty: compact size with 26K, 300W output
The unit is small for its class, measuring about 6.3 × 1.5 × 2.5 inches, but it’s packed with a 26,250mAh cell that has more capacity than the batteries in most competing models of equivalent capacity (20,000mAh).
That’s enough to recharge a modern 5,000mAh smartphone around 4–5 times, depending on efficiency and what you’re doing with the phone in between top-ups.
The total output is up to 300W on the ports. The pair of USB-C ports, meanwhile, can offer 140W each with a 22.5W USB-A available for legacy cords. Ports share power, as they do on other products, but the headroom here is uncommonly big: this bank can not only fast-charge a 14-inch MacBook Pro at full blast, but also top off a Steam Deck around 45W and still keep a phone humming along at blistering speeds.
Its high-wattage support is aligned with what we’ve seen in premium laptops and accessories that jet more electrons via USB-C Power Delivery 3.1. In practical terms, that means you can leave the heavy brick at home and still get near-maximum charge rates on devices that take between 100W–140W input.
Faster recharges for the bank with 250W input support
Recharging the pack is as cool as running your gear. Leveraging both USB-C inputs at the same time, you can pump about 250W into the bank, pushing it from zero to around 50% capacity in just over 13 minutes. Even just one USB-C input pumps out as much as 140W, still speedy and handy during a layover or cafe stop.
For travelers and field creators, it is the difference between a dead laptop and another hour of editing or playing games in real time.
Real-world capacity and efficiency: what to expect
Battery math matters. The 26,250mAh number translates to roughly 97 watt hours (26,250mAh × 3.7V ÷ 1,000), which is just on the high end of the typical limits set by airlines. Once you factor in conversion losses — which can mean anything from 70–80% efficiency in actual use — you’re still talking about anywhere between multiple full charges for a phone or meaningful power top-ups for a power-hungry laptop.
For example, a 67Wh ultrabook can usually achieve a nice partial refill, while a gaming handheld such as the ROG Ally or Steam Deck allows for several hours of additional play. The large wattage overhead can also benefit those with a phone that supports higher-speed charging standards.
Travel and safety tips for flying with power banks
Since the pack is just below the 100Wh limit, it should be accepted in carry-on luggage according to guidelines from the TSA and IATA.
Like any lithium-ion battery, it should be carried in your cabin bag (not checked luggage) and is best kept at a moderate state of charge when flying.
Its small size, too, has a valuable use in the real world: it fits into most jacket pockets or tech pouches without beefing up your kit.
Deal terms and value for Prime members and shoppers
The $179.99 discount is for Prime members, and availability can come and go based on stock. New subscribers frequently get a 30-day trial that can be used to unlock this pricing if it’s still available. It’s not the lowest we’ve seen historically — the lowest was approximately $169.99 — but it’s close, and most buyers shouldn’t feel shortchanged at this price given the premium build and features.
It’s in a different class than the less expensive 20,000mAh banks that peak around 65–100W.
If you’re charging a high-end laptop, camera, or several power-hungry devices at once on a regular basis, the time saved and flexibility are worth the extra money.
Who should buy this? Bottom line, if you need a small, airline-safe battery with laptop-style power output and a self-charging system that’s faster than most, it’s an uncommon combination to find. With $50 off, it’s a handy pickup ahead of the next big trip, or hectic stretch at work.
