Anker Laptop Power Bank, 25,000mAh Triple 100W USB-C Review

Travelers with several devices know the struggle—cables everywhere and battery anxiety on long journeys. A high-capacity power bank can really help, letting you keep your phone, laptop, and other gear powered up during flights or layovers.

One model that grabs attention is a 25,000mAh unit with triple USB-C ports. It’s built to handle several devices at once, and it doesn’t slow down under load.

What makes this charger stand out for travelers? Its flight-approved size, retractable built-in cables, and fast recharge capability. The downside: it’s bulkier than pocket-sized banks and costs more, so it’s probably not the best pick if you only need occasional top-ups.

Overview: Anker Laptop Power Bank, 25,000mAh Portable Charger

This power bank targets anyone needing a backup power source for more than just a phone. With 25,000mAh, you get enough juice to keep a laptop, tablet, and phone running during long trips.

Three USB-C ports each support high-watt charging. You can power a MacBook and still charge smaller electronics. The built-in retractable cables help reduce cable clutter, though they do add some bulk.

Highlights:

• Capacity: 25,000mAh for extended use across multiple devices.
• Ports: Three USB-C, one USB-A; up to four devices simultaneously.
• Design: Retractable cables keep things tidy, but may wear with heavy use.
• Travel: Under 100Wh (90Wh), so it’s airline compliant, though it weighs over 1 lb.

Triple 100W USB-C Ports

Three high-power USB-C ports let you charge multiple devices at the same time, each up to 100W. That means you can power a laptop, tablet, and phone together—no need to pick just one.

If you travel with several USB-C gadgets, this setup means you don’t have to haul around extra chargers. Everything runs from a single power bank.

What stands out:

• Flexibility: Charge different devices at once.
• Speed: High output reduces wait times for bigger electronics.
• Trade-off: Charging four devices at once can reduce overall efficiency.

Anyone who shares a charger or carries lots of gadgets will find the triple-port design offers more flexibility than most banks in this range.

Massive 25,000mAh Capacity

A 25,000mAh battery gives you a lot more power than smaller chargers. You’ll get multiple phone recharges or enough to keep a laptop running when there’s no outlet nearby.

What this means:

• Extended use: Fewer recharges needed for the bank itself.
• Laptop support: Big enough for devices that drain smaller banks fast.
• Travel trade-off: The extra capacity adds weight, so it’s not pocket-sized.

Compared to compact 10,000mAh models, this one takes away some of the stress about running out of power. But you do pay for it in size and weight.

Built-In and Retractable Cables

You’ll find built-in cables that retract when not in use, so you don’t have to pack extras. That keeps things tidy and helps prevent forgotten cords.

Retractable cables add convenience, but you lose some flexibility compared to using your own longer ones. If you need extra reach a lot, this could be a pain.

Key points:

• Built-in cables save space and cut clutter.
• Retractable design keeps things neat.
• Trade-off: Cable length is short, which isn’t great if outlets are far.

This setup is best for those who want fewer accessories to manage, but not ideal if you need long charging cords regularly.

Simultaneous Charging for Four Devices

You can plug in up to four devices at once. With three USB-C ports and one USB-A, you’re covered for both new and older tech—no need for extra adapters.

What works well:

• No more juggling multiple chargers.
• Built-in cables keep your bag organized.
• High output means laptops and tablets charge alongside phones.

What could be better:

• Charging speed may drop if you max out all four ports.
• Size and weight are noticeably more than single-device banks.

If you need to keep several devices powered on the go, this setup is practical. But you’ll notice the extra bulk.

Travel and Flight Approval

Airline rules can be strict about batteries. This power bank comes in at 90Wh, under the 100Wh limit for carry-on bags. You can pack it in your hand luggage without special approval.

Key travel notes:

• Must go in carry-on, never checked bags.
• Capacity sits just below the airline max, so no extra paperwork.
• Some airlines might ask to see the battery rating at security.

The size and weight might feel like a lot for shorter trips. But if you want reliable power on long flights, the trade-off is worth it.

Digital Display and User Experience

There’s a small digital screen showing the battery percentage. It’s a nice touch—no more guessing with blinking LEDs.

The display updates in real time as you connect or disconnect devices. It’s easy to see how much juice you’ve got left.

The screen only tells you the battery level, though. You won’t see detailed stats like output per port, which some pricier models include.

Highlights:

• Clear percentage readout for remaining charge
• Real-time updates when plugging or unplugging devices
• Simple interface, but just shows battery level

Pros and Cons

Pros

• High capacity: 25,000mAh means you can recharge laptops, phones, and tablets several times.
• Strong output: Each USB-C port supports up to 100W—enough for a MacBook and more.
• Built-in cables: Retractable design cuts down on clutter and forgotten cords.
• Travel-friendly: 90Wh rating meets airline carry-on rules.
• Multi-device support: Charge up to four devices at once.

Cons

• Size and weight: It’s bulkier than smaller banks; not ideal if you’re packing light.
• Limited port variety: Only one USB-A port, which could be annoying if you have older cables.
• Recharge time: Filling up a 25,000mAh battery still takes several hours.
• Cable wear: Retractable cables are handy but may not last as long as standard ones.
• Price point: More capacity and output means a higher price tag.

Customer Reviews

Buyers often mention the strong charging power and flexibility. Many like being able to charge laptops, phones, and tablets at the same time.

Travelers appreciate the flight approval, making it easy to bring on planes. The built-in cables and display also get frequent praise.

Positive themes:

• Retractable cables reduce the need for extras
• Display makes it easy to check battery level
• Stays cool when charging several devices
• Feels solid and well-built

Critical notes:

• Bigger and heavier than pocket-sized chargers
• Higher price than smaller banks
• Some think it’s too bulky for everyday, casual use

Reviews suggest you should weigh the size and cost against the convenience of fast, multi-device charging.

Who It’s For (and Not For)

This power bank works best for travelers, remote workers, or anyone who needs to keep multiple devices running away from outlets. If you’re always on the move with a laptop and phone, it could be a lifesaver.

It’s probably not for you if you want something ultra-light, or if you only need to top up your phone occasionally. People who value portability above all might find it too big.

Key Specs

• Capacity: 25,000mAh (90Wh)
• Ports: 3x USB-C (up to 100W each), 1x USB-A
• Weight: Just over 1 lb (varies by model)
• Cables: Built-in, retractable USB-C
• Display: Digital battery percentage
• Airline approval: Yes (under 100Wh limit)

Decision Factors and Performance

If you need to charge a laptop, the 100W USB-C output is a must. Built-in cables mean fewer things to forget, but they’re short. The large battery lasts through long flights or workdays, but it adds weight.

You’ll want to consider how much you value multi-device charging versus portability. The digital display is helpful, but simple.

What Sets It Apart

The triple 100W USB-C ports and retractable cables are rare at this capacity. Many competitors offer two ports or require you to bring your own cables. The clear, real-time battery display is also a nice touch.

Close Alternatives

1. Zendure SuperTank Pro

• Capacity: 26,800mAh
• Ports: Four USB-C
• Display: OLED with detailed stats
• Differences: More detailed display, slightly higher price, no built-in cables

2. Baseus Blade 20,000mAh Power Bank

• Capacity: 20,000mAh
• Ports: Two USB-C, two USB-A
• Display: LED percentage
• Differences: Slimmer, lighter, lower capacity, but less power for laptops

Both alternatives offer strong charging, but the Anker’s built-in cables and triple 100W output give it a unique edge for heavy travelers.

Verdict

The Anker 25,000mAh Laptop Power Bank offers a rare mix of high capacity, powerful output, and airline compliance. It’s not the lightest or cheapest option, but it’s a solid pick for anyone who needs to keep multiple devices charged on long trips.

If you value convenience, built-in cables, and don’t mind a little extra weight, it’s a smart choice. If pocketability is more important, look at something smaller. It’s a bit of a trade-off—but for the right user, it really delivers.

Frequently Asked Questions

How many full charges can I expect for my laptop with this Anker 25,000mAh power bank?

It depends on your laptop’s battery size. For ultrabooks with 40–50Wh batteries, you’ll usually get about 1.5–2 full charges. Larger laptops (70–100Wh) might get one full charge or a bit less.

What are the main differences between the Anker A1902311 and Anker A1695 models?

The A1695 is the newer 25,000mAh version with built-in, retractable cables, triple 100W USB-C ports, and a display. The A1902311 is older and lacks some of these features.

Can the Anker 25,000mAh power bank deliver enough power to charge high-wattage laptops?

Yes, up to a point. Each USB-C port supports 100W, which is enough for most modern laptops, including MacBooks and many Windows ultrabooks. Gaming laptops that draw more than 100W might charge slowly or only maintain their battery level.

Will the built-in cables work with all my devices?

The built-in cables are USB-C, so they work with most modern devices. If you have gadgets that use micro-USB or Lightning, you’ll need an adapter or your own cable.

How long does it take to recharge the power bank itself?

With a high-wattage charger (at least 60W), it usually takes about 2.5 to 3.5 hours to fully recharge from empty. Lower-wattage chargers will take longer.

Is it safe to bring this power bank on international flights?

Yes. At 90Wh, it’s under the 100Wh limit for most airlines worldwide. Always pack it in your carry-on, not checked luggage, and be ready to show the battery rating if asked.
