Best Portable Power Bank 2026 — Our Research Pick: Anker 737 (PowerCore 24K)

Most phone power banks can’t meaningfully charge a laptop. Anker’s 737 was built specifically to close that gap, and tech outlets reviewing it long-term have consistently called it the best all-around laptop-capable power bank under $120, thanks to genuine 140W output rather than a marketing-only spec.

Our Pick: Anker 737 (PowerCore 24K) — around $109.99

What Owners Actually Say

Heavy travelers who need to charge multiple devices report strong results. One owner charges “my macbook at least twice; my iphone 17 pro max at least 4 times” on a single charge and specifically liked the screen showing live charging status. Another called the display “fantastic,” saying it gives “all the information you need in order to know what is going on with the inputs and outputs” once you’re used to the higher price point.

Passthrough charging with high-wattage laptops is the most specific complaint — one reviewer with a Dell laptop needing 100W found the passthrough mode “more limited than I hoped” for certain input/output combinations, and another said their unit needed recharging after only three devices, well short of an older Anker model they’d owned. If you plan to charge a laptop directly while the bank itself is charging, it’s worth checking your laptop’s exact wattage requirement against Anker’s passthrough specs first.

Pros

• 140W max output across 2 USB-C and 1 USB-A port — enough to fast-charge most laptops, not just phones
• 24,000mAh capacity with a real-time OLED display showing input/output wattage and estimated recharge time
• Reviewers report Anker’s charging electronics reliably protect connected devices over years of daily use
• Compact enough for a daily bag despite the high capacity, compared to bulkier laptop-charging power banks

Cons

• At 24,000mAh and with full electronics, it’s noticeably heavier than phone-only power banks in the same price range
• Airlines cap carry-on power banks around 27,000mAh (100Wh) — this sits safely under that, but always double check your specific airline’s policy

FAQ

Can it actually charge a MacBook or similar laptop?

Yes — reviewers confirm 140W is enough to fast-charge most USB-C laptops, though very high-power gaming laptops may charge slower than their wall adapter.

Is the OLED display actually useful or just a gimmick?

Owners report genuinely using it to track remaining charges and estimate recharge time, rather than guessing from a simple LED dot indicator like cheaper power banks use.
