The Best Power Banks of 2026
Best power banks of 2026: Anker 737, plus top picks for travel, fast charging, and compact everyday carry. Expert-tested portable charger reviews.

Our Top Picks at a Glance

Anker 737 Power Bank 24000mAh
Our verdict: For most people, the Anker 737 Power Bank 24000mAh is the smartest buy in this category — strong performance, reliable build quality, and excellent value for the price.
A good power bank is one of the most useful things you can carry, and a bad one will fail you the moment your flight lands. The difference comes down to actual capacity (not just marketed mAh), charging speed, and how many devices you can top up simultaneously. Here are the portable chargers that held up in real testing.
Anker 737 Power Bank 24000mAh — Best Overall
The Anker 737 doesn''t do anything flashy — it just delivers. The 24,000mAh capacity charges most laptops to full twice and keeps a phone going for 5-6 days. The display shows exact battery percentage, wattage input/output, and estimated time remaining — genuinely useful information instead of the vague LED dots you get on most competitors. 140W bidirectional charging means it also charges itself quickly.
- 140W total output — charges MacBook Pro at full speed
- Smart digital display with wattage and time remaining
- 24,000mAh — enough for 2 full laptop charges
- USB-C and USB-A ports for mixed-device charging
Verdict: The Anker 737 is the power bank we''d recommend to almost everyone who travels with a laptop.
Anker Nano 10000mAh — Best for Daily Carry
For people who just need a phone top-up on a long day, lugging around a 24,000mAh brick is overkill. The Anker Nano fits in a jacket pocket and weighs just 180 grams while still delivering 30W fast charging. It charges itself and a connected device simultaneously, and the compact form factor makes it easy to toss in a bag without thinking about it.
- Pocket-sized at 180g — genuinely portable
- 30W fast charge — fills an iPhone in about 1.5 hours
- Simultaneous charging of itself and a connected device
- Available in multiple colors
Verdict: The Anker Nano is the one you''ll actually take everywhere rather than leaving at home because it''s too heavy.
Baseus Blade 100W — Best for Laptop Power
The Baseus Blade is shaped more like a thin wallet than a traditional power bank, and its 20,000mAh capacity at 100W output covers most USB-C laptops including the 15-inch MacBook Air and most Windows ultrabooks. The slim profile makes it easier to pack in a laptop sleeve, and the dual USB-C design means you can charge two laptops simultaneously — useful for power users and road warriors.
- Slim wallet form factor fits in a laptop sleeve
- 100W total output — compatible with most USB-C laptops
- 20,000mAh — roughly 1.5 full laptop charges
- Dual USB-C + USB-A outputs
Verdict: For travelers who need laptop power in the slimmest possible package, the Baseus Blade is exceptional.
What to Look For
- Real-world capacity: Expect about 60-70% of the rated mAh to reach your devices — power conversion losses are real. A 10,000mAh bank charges a 4,000mAh phone roughly 1.5 times.
- Output wattage: For phones, 20-30W is fast enough. For laptops, you need at least 60W — ideally 100W or more for larger notebooks.
- Airline rules: Most airlines allow up to 100Wh (roughly 27,000mAh) in carry-on. Anything larger requires approval and usually isn''t worth the hassle.
- Pass-through charging: Some banks can charge themselves and a connected device simultaneously — very useful when hotel outlets are scarce.
The right power bank depends entirely on your situation. Commuters should optimize for size; long-haul travelers should optimize for capacity and wattage. Whatever you choose, buy from a reputable brand with proper safety certifications — cheap no-name power banks occasionally become a serious fire hazard.
