Anker Laptop Power Bank, 25,000mAh Portable Charger with Triple 100W USB-C Ports, Built-in Retractable Cables, Flight-Approved for Travel, iPhone 17/16 Series, MacBook, Samsung, and More Review

If you've ever sat cross-legged on an airport floor next to the only available outlet, this power bank was designed specifically to end your suffering.

The Anker 25,000mAh Laptop Power Bank has been making the rounds in frequent traveler communities — and for good reason. It's not just a big battery. It's a rethink of what a travel power solution should look like. Three USB-C ports, each capable of 100W, built-in retractable cables so you're not fumbling through your bag for a wire, and it's flight-approved under TSA/IATA rules. On paper, this thing ticks every box.

What Frequent Travelers Actually Think

In a popular r/ManyBaggers thread asking frequent travelers for their top non-bag essentials, the Anker 25K 165W with built-in retractable cables was called out by name as a standout pick — notably in a category that dominated the entire thread. Power and charging gear was the most mentioned category overall, mentioned more than noise-cancelling headphones, neck pillows, or anything else. And within that category, the preference was clear: travelers want a combo unit that doubles as a charger so they carry one device instead of two.

That's exactly the value proposition here. Charge your MacBook, your phone, and a travel companion's device simultaneously — without hunting for three separate ports on a hotel desk or competing for outlets at the gate.

The Retractable Cables Are the Real Feature

Built-in retractable cables sound like a gimmick until you've used them. The practical reality is that most travelers cite cable management as one of their biggest daily annoyances — short USB-C cables, tangled cords, and the inevitable moment you realize you left your only cable in the hotel room. Having the cables baked right into the unit means one less thing to lose and one less thing to pack.

The r/ManyBaggers thread explicitly flagged retractable cables as part of the "minimal cable kit" goal — fewer cables covering all devices. This power bank aligns with that philosophy directly.

Specs That Hold Up to Scrutiny

At 25,000mAh, this sits just under the 100Wh airline limit, which is what makes it flight-approved. That capacity is enough to fully charge most laptops once and still have juice left for phones. The triple 100W USB-C configuration means you're not stuck with one fast port and two slow ones — all three ports can deliver serious wattage. Compatibility covers iPhone 17/16 series, MacBook, Samsung Galaxy, and essentially anything that charges over USB-C.

For context, the competing Anker 737 (24,000mAh, 140W, smart display) has been spotted at $99.99 CAD on deals threads — the 25K with retractable cables has hit $87.99 USD on sale from a regular price of $134.99. At that sale price, the value proposition is hard to argue with.

What to Watch Out For

This isn't a lightweight unit. A 25,000mAh battery capable of 100W output across three ports isn't going to slip into your jacket pocket — this is a bag item. Travelers who prioritize ultralight carry-on setups may find it bulkier than ideal. If you're a one-bag minimalist who rarely needs to charge a laptop on the go, a smaller 10,000mAh bank might serve you better and weigh significantly less.

There's also the question of the retractable cables over time. Built-in mechanisms are convenient until they're not — retractable cable mechanisms can wear out with heavy daily use, and unlike a separate cable, you can't simply swap it out. This is a durability consideration worth keeping in mind for anyone who plans to use this as their daily driver for years.

Who Should Buy This

This is made for the road warrior — the person who travels 3–4+ times a month, carries a laptop as their primary work machine, and is constantly juggling device charging in airports, lounges, trains, and hotel rooms. The combination of high capacity, multi-device fast charging, and built-in cables makes it a genuinely practical all-in-one solution rather than just a spec-sheet win.

Light travelers who only charge a phone and maybe some earbuds? You'd be carrying more battery and weight than you need. But for anyone who has ever missed a meeting because their MacBook died mid-flight, this is the answer.
