Best Portable Power Banks of 2026What 52 reviewers actually think, trust-weighted

Portable power banks are one of the most reviewed accessory categories online, and the consensus is fragmented: high-capacity laptop banks impress on paper but reviewers repeatedly flag efficiency losses and port-sharing limits, while pocket-sized models win on real-world convenience. This roundup synthesizes what verified-purchase reviewers, specialist communities like r/UsbCHardware and r/Ultralight, and independent testers have written, weighted by trust tier rather than marketing claims. Where high-trust sources disagree with the marketing or with the crowd, we surface it.

★★★★★4.5(81,415)88Great

Across the reviewers we read, the INIU 45W is the most consistently praised pick in this category. A high-trust verified-purchase reviewer on Best Buy called it the best portable charger they've owned, citing the compact size and fast charging, and the high-trust r/Ultralight community went further, with one initial-review thread describing it as 'probably the best all-round on the market just now.' That community's main suggested improvement was bumping input above its current rate rather than any fundamental flaw.

Frequently asked

5 questions
How many mAh do I actually need in a power bank?
Reviewers generally point to 10,000mAh for one to two phone top-ups in a pocketable package, and 20,000mAh or more if you want multiple charges or to top up a tablet or laptop. Note that rated capacity is at the cell level: specialist communities repeatedly point out real-world delivered capacity is meaningfully lower due to voltage conversion losses, so plan for roughly 60-70% of the printed number reaching your device.
Can a power bank charge a laptop?
Yes, if it supports USB-C Power Delivery at a high enough wattage. Reviewers recommend 65W or more for most ultrabooks and 100W for power-hungry laptops. A recurring caveat in specialist threads is that advertised 'total' wattage figures (like 145W or 165W) are split across multiple ports, so a single port may cap lower than the headline number.
Are built-in cables worth it on a power bank?
Verified-purchase reviewers and community threads broadly like built-in and retractable cables for travel convenience, since there's one fewer thing to forget. The most common complaint is that the integrated USB-C connector can be too thick for some phone cases, and that a built-in cable is a single point of failure if it wears out.
Is Amazon's star rating a reliable way to pick a power bank?
It's a useful signal but not a verdict. A 4.5-star average across tens of thousands of reviews is informative, but Amazon reviews are gameable, and several models here score well on Amazon while independent lab testing ranked them poorly for efficiency. Cross-checking against independent testers and specialist communities is the better approach.
Can I take a power bank on a plane?
Most consumer power banks in this roundup fall under typical airline limits (100Wh), which covers the common 20,000-25,000mAh models, and several are marketed as flight-ready. Reviewers advise carrying power banks in your carry-on, never checked luggage, and checking your specific airline's current rules.
