Top 3 Laptop Power Banks Reviewed

#1 Anker 25,000mAh 165W Laptop Power Bank: Best Overall

Why We Picked It

The Anker 25,000mAh 165W Laptop Power Bank leads because it pairs a 165W total output with three USB-C ports rated up to 100W each, according to the listing. That gives it the most output headroom of the three top picks, so it can charge a laptop and a second device at the same time without a second charger.

Two built-in USB-C cables, one retractable and one short strap-style cable, remove the need to carry a separate laptop cable. Compared with the UGREEN Nexode 25000mAh 145W Power Bank, it lists a higher total output, while the UGREEN lists a higher single-port peak of 140W. Both list the same 25,000mAh capacity.

Key Specifications

• Capacity: 25,000mAh
• Output: 165W total, up to 100W per USB-C port
• Ports: two built-in USB-C cables, one USB-C port, one USB-A port
• Airline: manufacturer states it complies with 100Wh airline restrictions
• Warranty: 18 months

Pros	Cons
Highest total output of the top three Built-in cables reduce what you carry Manufacturer states it is carry-on friendly	Built-in cables cannot be swapped if one is damaged Listed depth of 1.93 inches is thicker than the other two top picks

Things to Consider

Confirm your laptop’s charger rating before buying. Each USB-C port is rated up to 100W, so a laptop that ships with a larger charger may not charge at full speed from one port. The 165W figure is a total, so check the per-port rating when you plan to charge several devices at once, and compare the listed depth with the space in your bag.

Best For

Remote workers and frequent flyers who charge a laptop and a phone together and want the cables built in.

Skip It If

Skip it if you want replaceable cables or only charge a phone and tablet, since the built-in cables and high total output add capability you may not use.

See the Anker 25,000mAh 165W Laptop Power Bank on Amazon.

#2 UGREEN Nexode 25000mAh 145W Power Bank: Best for Larger Laptops

Why We Picked It

The UGREEN Nexode 25000mAh 145W Power Bank ranks second because it lists up to 140W from a single USB-C port, the highest single-port figure among the top three. That matters for larger laptops whose original chargers are rated well above 100W, since one port can cover that demand.

It has three USB-C ports and a digital display that shows remaining battery, and the listing says it recharges in about two hours from a 65W or higher PD charger. Against the Anker, it trades built-in cables for a higher single-port peak and a larger body, with a listed weight of 1.26 pounds. Against the UGREEN Nexode 100W 20000mAh Power Bank, it adds capacity and output.

Key Specifications

• Capacity: 25000mAh
• Output: 145W total, up to 140W on one USB-C port
• Ports: three USB-C
• Size and weight: 6.30 x 3.18 x 1.05 inches, 1.26 pounds
• Recharge: about two hours with a 65W PD charger, per the listing

Pros	Cons
Highest single-port output of the top three Digital display shows remaining battery Listing says a 5A USB-C cable is included	Heaviest of the top three by listed weight No USB-A port for older accessories

Things to Consider

Full output depends on the right accessories. The listing says to use the included 5A USB-C cable or another certified 5A cable, and a 65W or higher adapter for the stated recharge time, while a 20W adapter takes up to six hours. Compare the listed weight with the other picks if you plan to carry it every day.

Best For

Owners of larger laptops with high-wattage chargers who want one port to carry the whole load.

Skip It If

Skip it if your laptop charges at 65W or less or you want a lighter bag, since the extra output goes unused and the weight is the highest among the top three.

See the UGREEN Nexode 25000mAh 145W Power Bank on Amazon.

#3 UGREEN Nexode 100W 20000mAh Power Bank: Best for Everyday Carry

Why We Picked It

The UGREEN Nexode 100W 20000mAh Power Bank takes third place as the balanced choice. It lists 100W output across two USB-C ports and one 22.5W USB-A port, which covers laptop chargers up to 100W while keeping the body to 5.47 x 3.23 x 1.02 inches and 0.93 pounds.

It includes a USB-C cable designed for 100W and a digital display, and the listing says a full recharge takes 1.6 hours using the 65W input on its first port. Against the two models ranked above it, it offers less capacity and less output, but it is lighter than the UGREEN Nexode 25000mAh 145W Power Bank.

Key Specifications

• Capacity: 20000mAh
• Output: 100W
• Ports: two USB-C, one USB-A at 22.5W
• Size and weight: 5.47 x 3.23 x 1.02 inches, 0.93 pounds
• Recharge: 65W input, about 1.6 hours per the listing

Pros	Cons
Includes a USB-C cable designed for 100W Digital display shows remaining battery Lighter than the UGREEN 145W model	Lowest capacity and output of the top three USB-A port is limited to 22.5W

Things to Consider

Check that your laptop’s charger is rated at or below 100W. The listing notes that many regular USB-C cables support only 60W, which can leave a laptop charging slowly or not at all, so use the included cable or one rated for 5A and 100W. Confirm the capacity suits your day, since it is the lowest of the top three.

Best For

Commuters and students who carry a laptop daily and want a mid-size bank with the cable included.

Skip It If

Skip it if you want the most capacity or own a laptop charger rated above 100W, since this model lists the lowest capacity and output of the top three.

See the UGREEN Nexode 100W 20000mAh Power Bank on Amazon.

How to Choose a Laptop Power Bank

Capacity and What It Means for Your Device

Capacity tells you how much energy the bank stores, but a laptop battery is usually rated in watt-hours while many banks advertise milliamp-hours. Check the watt-hour rating of both when the listing provides it, and expect some energy to be lost as heat during charging. A larger bank covers a longer day away from an outlet but adds size and weight. Match capacity to how long you work unplugged, and confirm the exact figures for the model you choose, since versions of the same product can differ.

Output and Port Types

Output decides whether a laptop charges at full speed. Find the wattage printed on your laptop’s original charger and choose a bank whose single-port rating meets or exceeds it. A bank with a lower rating may charge the laptop slowly, or only while it is idle. Total output is shared when several ports are in use, so look at the per-port rating as well. USB-C ports carry laptops and phones, while USB-A ports suit older accessories but usually deliver less power.

Charging Standards and Speed

Look for USB-C Power Delivery, the standard most modern laptops use to negotiate charging power. Some listings also mention PPS or Quick Charge for phones. The cable matters as much as the bank: many USB-C cables support less power than a laptop needs, and higher outputs generally require a cable rated for the full current. Use the cable included in the box or one the manufacturer recommends. If a laptop charges slowly, suspect the cable or the charger rating before blaming the bank.

Size, Weight and Airline Rules

A laptop bank lives in a bag, so thickness and weight affect how often you carry it. Slim designs slide into a sleeve, while compact designs save footprint. For flying, the FAA’s PackSafe guidance says power banks and spare lithium batteries must stay with the passenger in the cabin, and airlines set limits by watt-hour rating. Manufacturers often state airline compliance in the listing, but read the rating printed on the unit and check your airline’s current policy before travel. Never pack a damaged or swollen battery.

Recharge Speed and Pass-Through

A bank that takes many hours to refill is hard to rely on. Check the listed input power and recharge time, and use a charger of the recommended wattage to reach that speed. Some models can charge devices while they recharge themselves, which is called pass-through, but support varies and is not always documented. If you plan to rely on it, confirm it on the product page or in the manual. Follow the manual’s guidance on storage temperature and ventilation. If you need far more energy than a bank offers, see our Portable Power Stations.

How We Evaluate Laptop Power Banks

We evaluate laptop power banks by comparing manufacturer specifications, Amazon listing information and available buyer ratings. We weigh each model on fit for laptop charging, capacity, output and ports, size and weight, charging standards, build and safety information, and overall value. Amazon does not supply ratings for the products in this guide through our data source, so the rankings rely on published specifications rather than review scores. Specifications can change between versions, so confirm capacity, rated output, port types and device compatibility for the exact model before you buy. Commissions do not affect rankings, and we update the guide when listings change.

Frequently Asked Questions

Can a power bank charge a thin laptop?

Yes, if it supports USB-C Power Delivery and its per-port output meets your laptop’s charger rating. Many thin laptops draw less power than larger models. Check the rating on your original charger and use a cable that supports that power, since a weaker cable can slow charging.

Are laptop power banks allowed in carry-on luggage?

Spare lithium batteries generally belong in carry-on bags, and airlines set limits by watt-hour rating. Several manufacturers, including Anker and Baseus, state that their models meet airline rules, but check the rating printed on the unit and your airline’s current policy before you fly.

Can one power bank charge a laptop and a phone at the same time?

Many can, but the output is shared. The Anker 25,000mAh 165W Laptop Power Bank lists a 165W total with up to 100W per USB-C port. Check the total and per-port ratings so the laptop still receives enough power while the phone charges.

Does a laptop power bank support pass-through charging?

Support varies by model. The UGREEN Nexode 25000mAh 145W Power Bank listing describes simultaneous charging of the bank and connected devices, but not every listing addresses it. Check the product page and manual before relying on it, especially with a laptop you need at full speed.

How should a laptop power bank be stored?

Check the manual for the manufacturer’s guidance. In general, keep the bank in a cool, dry place away from heat sources, avoid leaving it in a hot car, and do not use it if it is swollen, damaged or unusually hot. Store it with some charge rather than fully drained if the manual recommends it.

Final Verdict

The Anker 25,000mAh 165W Laptop Power Bank is the strongest overall option in this guide because it lists the highest total output of the top three and builds the cables in. If you carry a larger laptop with a high-wattage charger, the UGREEN Nexode 25000mAh 145W Power Bank is the alternative to consider, since it lists up to 140W from a single port. Whichever you choose, match the bank’s per-port output to your laptop’s original charger, use a cable rated for that power, and check airline rules for the exact watt-hour rating before you fly. That approach matters more than any single spec on this list.
