Premium Pick
Pick #1 — Best for Laptops and Heavy Users
Anker Prime 27,650mAh 250W Power Bank
250W output — charges a MacBook Pro at full speed
Android Central called the Anker Prime 27,650mAh "the best power bank I've ever used" after testing dozens over three years, and Macworld confirmed it delivers a near-full charge to a 16-inch MacBook Pro. The 250W total output splits across three ports — two USB-C and one USB-A — with up to 140W on a single USB-C port for PD 3.1 laptop charging. A smart digital display shows real-time wattage input and output, remaining battery percentage, and estimated time to full. TSA-approved for carry-on travel. The Anker app provides detailed usage stats. For anyone who regularly travels with a laptop and wants a single power bank that handles everything, this is the definitive pick.

Pick #2 — Best High-Capacity All-Rounder
Anker 737 Power Bank 24,000mAh
140W output, digital display, charges phones and laptops
The Anker 737 sits one tier below the Prime in Anker's lineup but still delivers 140W total output — enough to charge most laptops at a respectable speed while simultaneously charging a phone. Two USB-C ports and one USB-A, a smart digital display showing real-time watts and remaining charge, and 24,000mAh for roughly 4–5 full iPhone charges or a full MacBook Air top-up. TSA-approved. For anyone who wants strong laptop-capable power bank performance without the Prime's premium price, the 737 is the sweet spot in Anker's range.

The Baseus Blade solves the problem that most laptop-capable power banks have — they're too big and heavy to carry casually. Its ultra-slim blade profile is roughly the thickness of a few credit cards stacked, making it genuinely pocketable despite a 20,000mAh capacity and 100W output. That 100W is enough to charge most laptops at a useful speed, making it the pick for professionals who want laptop charging capability without the bulk of the Anker Prime or 737. LED digital display shows remaining battery. Four ports including two USB-C. Wirecutter has featured it as a standout slim laptop power bank option.

Pick #4 — Best Budget High-Capacity Pick
INIU 20,000mAh 22.5W Power Bank
20,000mAh at the most accessible price on this list
The INIU 20,000mAh is the right pick for anyone who needs high capacity at a budget price and doesn't need laptop charging. 22.5W fast charging keeps phones topped up quickly across three simultaneous ports — USB-C and two USB-A — and the 20,000mAh capacity provides roughly 4–5 full iPhone charges. LED indicator shows remaining battery in four segments. Compact for its capacity, reliably reviewed on Amazon with tens of thousands of ratings. For everyday phone and tablet charging during travel, camping, or long days away from an outlet, the INIU delivers everything needed at the most accessible price on this list.

Waterproof, drop-proof, and built for the outdoors
The Nestout is the power bank for people who take their gear outdoors. IP67 waterproof rating means it survives submersion up to 1 meter for 30 minutes — rain, puddles, and accidental drops into water are all handled without concern. The ruggedized casing handles drops and impacts that would crack standard power banks. A built-in flashlight adds utility for camping and hiking, and the high-capacity battery handles multi-day trips without access to a wall outlet. For overlanders, campers, hikers, and anyone who regularly uses their phone in wet or rough conditions, this is the only power bank on this list built for that environment.

Genuinely slim — the one you'll actually carry every day
The INIU 10,000mAh Slim is the power bank that solves the biggest problem with power banks — people leave them at home because they're too heavy or bulky to carry daily. The slim profile fits in any pants pocket without discomfort, 10,000mAh provides 2–3 full phone charges, and the USB-C port supports fast charging for quick top-ups. A single LED indicator shows remaining charge. Under $25, this is the easiest power bank purchase to make — the one you buy, put in your bag, and forget about until you need it. An excellent gift that gets used constantly.

What is the best power bank for charging a laptop?
The Anker Prime 27,650mAh 250W is the best laptop power bank available — it charges a 16-inch MacBook Pro at near wall speed and has been called the best power bank ever tested by Android Central. For a more affordable laptop-capable option, the Anker 737 (140W) or Baseus Blade (100W slim) are strong alternatives.
Are power banks allowed on planes?
Yes, but they must go in carry-on luggage — never checked bags. The standard TSA limit is 100Wh. The Anker Prime is right at that limit. Always check your specific airline's policy as international carriers sometimes have stricter rules.
What is the best budget power bank?
The INIU 10,000mAh Slim is the best budget everyday power bank — under $25, genuinely slim enough to carry daily, and delivers 2–3 full phone charges. For more capacity on a budget, the INIU 20,000mAh at around $30–35 is the best value high-capacity pick.
