An extremely popular high‑capacity portable charger just rolled to its lowest price ever. The Anker Laptop Power Bank (25K, 165W) is on sale for $87.99 as of this writing, $47 off through a limited‑time deal on Amazon; that even includes both Black and Silver finishes. If you’re on the go and want a single pack that can power up both laptops and phones, this is a solid buy for commuters, students, and cross‑continent frequent flyers.
It’s a simple hook: desktop‑class power in a travel‑friendly brick form factor, with a design that thoughtfully includes baked‑in cables and enough ports to drive an entire mobile setup. At less than $90 it’s cheaper than most slower, lower‑capacity rivals, and comes with the premium build quality you expect from the brand.

What Makes This Deal Stand Out Compared to Past Pricing
Shopper price‑tracking services, frequently relied upon by consumers, list this as the historical low for the model. And it’s not your typical markdown, either — the pack usually falls closer to the $130 mark with rare occasional dips. If you’ve been in the market for upgrading an older power bank, this is the kind of floor price that tends not to last long.
Crucially, the discount is good no matter which colorway you want — there’s no need to sacrifice finish to get in on the savings. But as with many time‑bound offers, good timing is stock‑dependent.
Power and Ports for Laptops and Phones with 165W Output
This one combines a 25,000mAh battery with up to a 165W output — that's serious beef for a travel charger. Each of the three USB‑C ports can provide up to 100W (USB Power Delivery), while a USB‑A port gives up to 33W for your legacy cables. Plug in multiple devices and the wattage shares intelligently, so a laptop and phone might together fast‑charge without drama.
In practice, that means it can easily keep an ultrabook (provided you have something like a MacBook Air or a 13‑inch‑class Windows machine) running throughout the course of a day, or even charge a phone or earbuds several times over. That covers a pretty wide range, as many thin‑and‑light laptops pull 45–65W and even 14‑inch pro notebooks can sip 96–100W over USB‑C (it’s all the bank can feed out of one port), but it’s there.
Real‑World Capacity Explained with Usable Watt‑Hours Math
On paper, 25,000mAh looks massive. In watt‑hours, the pack comes to around 92.5Wh (25,000mAh × 3.7V ÷ 1,000). After the standard conversion losses you get in all portable chargers — let’s say 20–30% depending on cable quality, temperature, and load — you would probably achieve about 65–75Wh of usable energy.
That’s enough to recharge a modern, 5,000mAh smartphone three to four times or add roughly 1.3–1.5 complete charges to a 52Wh laptop battery such as the MacBook Air’s (it’s close). For gaming handhelds like those that hail from the 40Wh era, you’re looking at nearly two full refills. These are ballpark figures, but they jibe with consumer tech reviewers’ reports of typical independent lab testing standards.
Built‑In Cables and a Rugged Design Suited for Daily Carry
This model is unique in that it comes with two built‑in USB‑C cables. One of those clips out from the top for quick access and is also a lanyard; both are rated to survive 20,000 bends — eliminating one common failure point for your everyday carry. As there are no more dangling cables in your bag, they don't contribute to friction when you need juice on the go.
The chassis feels well constructed in a good way; the finish is smooth and the tolerances around the ports are tight. A longer‑than‑average, 18‑month warranty provides extra peace of mind when compared to the standard 12‑month coverage from many accessory makers. And that matters for a device you’ll probably be chucking in and out of backpacks, seat‑back pockets, etc., all the time.
Travel Ready and Airline Rules for Carry‑On Battery Packs
It's about 92.5Wh, just under the 100Wh that is the FAA limit for carry‑on batteries, so it's cleared for flights without special approval.
As always, power banks need to be placed only in carry‑on bags, not checked luggage — advice repeated by major airlines and transportation authorities.
If you carry more than one device — a USB‑C laptop, phone, tablet, and buds, say — the four‑port design makes it easier to bulk charge at the gate or in flight while keeping cables organized.
Who Should Buy This and What to Consider Before Purchasing
This one is a good pick for remote workers, students, creators, or travelers who prefer one battery to serve everything from a work laptop to a leading phone. If your laptop has a barrel socket or draws more than 165W under load, you’ll need to check for USB‑C power compatibility first; many high‑end gaming laptops still rely on higher‑wattage bricks for top performance.
At this price, it undercuts a lot of 20,000mAh 65W competition while offering more headroom and better I/O. Industry reviewers frequently cite the brand’s reliability, too; practical touches like built‑in cables, four ports, and a robust warranty make it easier to recommend than lowest‑common‑denominator bricks that look cheaper on paper but prove frustrating in daily use.
Bottom line: if you’ve been holding out for an above‑all‑else, laptop‑capable portable charger without the above‑all‑else price, this once‑in‑too‑long drop to $87.99 is the time.
