Best Power Banks That Can Charge a Laptop in 2026

Laptop-class power banks are portable batteries with USB-PD high enough to charge a notebook, not just a phone. If you work from coffee shops, fly with a thin MacBook or Windows ultrabook, or need a second charge after the wall brick stays home, this is the product class. If you only ever plug in at a desk, buy a wall GaN brick instead (see Anker 737 vs UGREEN Nexode 140W). Those are AC wall chargers. This roundup is about battery packs with USB-C in and out.

The floor here is honest USB-PD around 60W or higher so a 13 to 16 inch class laptop can take a meaningful charge. Capacity marketing in mAh is noisy; watt-hours (Wh) are what airlines care about. Under about 100Wh is the easy carry-on band. Up to about 160Wh usually needs airline approval. Pair any bank with a real high-watt USB-C charging cable, not a charge-only mystery cord.

What to Look For

Match PD wattage to the laptop brick. A 65W MacBook Air is happy on a 65 to 100W bank. A 96 to 140W class MacBook Pro or gaming ultrabook wants a bank that can actually negotiate those watts on USB-C1. Shared multi-port totals are marketing; the single-port laptop number is what matters.

Trust Wh more than mAh. Cell mAh at 3.6V converts to Wh. Airlines use Wh. Listings that hide Wh or invent "equivalent mAh" are a red flag. Under ~100Wh is the painless carry-on story. Confirm the printed Wh on the case before a flight.

USB-C bidirectional is the modern default. You want USB-C that can charge the bank (input) and charge the laptop (output). Pass-through (charge bank and laptop at once) is useful when honest; many packs throttle hard or get warm, so treat it as a convenience, not a desk replacement.

PPS helps phones more than most laptops. Programmable Power Supply is great for Samsung and some Android fast-charge paths. For laptop PD, focus on fixed PD PDOs and EPR/PD 3.1 ceilings when the bank advertises 140W-class output. See USB-PD for the protocol basics.

Cables and wall twins are separate SKUs. A bank without a 5A USB-C cable will leave watts on the table. Charge-only cords from the 100W cable roundup are fine for bricks. Wall GaN twins like the Anker 737 vs UGREEN Nexode comparison are not substitutes for a battery pack.

Best Overall: Anker 737 Power Bank (PowerCore 24K)

The Anker 737 PowerCore 24K is the default laptop bank: about 24,000mAh, up to 140W USB-PD 3.1 output, dual USB-C plus USB-A, and a smart display that shows watts and recharge time. It sits in the easy airline Wh band and has the review volume to show real MacBook and Windows laptop use, not phone-only marketing.

Who it is for: anyone who wants one proven bank for a USB-C laptop plus phone on travel days. Who should skip it: buyers who need the absolute thinnest pack, or who only charge phones.

Best for Flights: Anker Prime Power Bank (27,650mAh, 250W)

The Anker Prime 27,650mAh 250W is the high-ceiling travel pick. Anker lists about 99.54Wh, which is the TSA under-100Wh carry-on story, while still advertising up to 140W to a laptop in a 250W multi-device total. App monitoring and fast dual-input recharge are the extras; the Wh label is why it wins the flights award.

Best for flyers who want max laptop watts without crossing 100Wh. Skip if budget matters more than the 250W multi-device ceiling.

Best Value: UGREEN Nexode 25,000mAh 145W

The UGREEN Nexode 145W bank is the value laptop pack: about 25,000mAh (~90Wh class), USB-C1 up to 140W with a 145W total, digital percentage display, and a street price that usually undercuts Anker Prime while still speaking PD 3.1. It is the pick when you want 100W-plus laptop output without paying flagship Anker money.

Best for MacBook and Windows USB-C laptops when price-per-watt matters. Skip if you specifically want Anker's app or the Prime's 250W multi-device ceiling.

Best Budget: INIU 25,000mAh 100W Compact

The INIU 25,000mAh 100W bank is the budget laptop-capable pack: 100W USB-C output, airline-safe capacity class, and a smaller footprint than soda-can banks. It will not match 140W Anker or UGREEN peaks on a hungry 16-inch Pro, but it is honest 100W PD for Air-class and many 65 to 100W Windows notebooks at the lowest street price on this list.

Best for students and travelers who need laptop top-ups without spending triple digits. Skip if your notebook brick is firmly above 100W and you refuse to throttle.

Best Slim Travel: Baseus Blade 20,000mAh 100W

The Baseus Blade 100W is the flat, briefcase-friendly shape: about 20,000mAh, 100W USB-C PD, dual USB-C plus dual USB-A, and a live power display. Capacity is lower than the 24 to 27K banks above, so treat it as a slim day-trip and layover pack rather than a weekend battery.

Best for travelers who prioritize bag thickness over maximum Wh. Skip if you need multi-day laptop autonomy from one charge.

The Bottom Line

Start with the Anker 737 PowerCore 24K when you want the proven 140W laptop bank. Take the Anker Prime 27K when the printed ~99.5Wh flight label and multi-device ceiling matter more than price. Choose the UGREEN Nexode 145W for 140W-class value, the INIU 100W when budget leads, and the Baseus Blade when a flat pack beats another half-cycle of capacity. For wall chargers at a desk, use the Anker 737 vs UGREEN Nexode GaN comparison; for the cable that unlocks these watts, stay on the 100W USB-C cable guide.
