4 Best Portable Power Banks 2026 — Tested & Ranked for Capacity, Speed & Travel

🥇 Best Overall: Anker 737 PowerCore 24K

StorageReview confirmed the Anker 737 delivers “140W Power Delivery 3.1 and bi-directional technology” enabling both 140W laptop charging and approximately 1-hour self-recharge. The OLED display shows real-time input and output wattage, estimated time to empty and cycle count — a level of information no budget power bank provides. At 86.4Wh it sits safely below the 100Wh TSA limit. WorldTimesNow tested it and confirmed it is “arguably the best tech investment you can make in 2026” for content creators, business travelers and digital nomads. The 630g weight is the honest trade-off for 140W portable power.

🏆 Thinnest Laptop Bank: Baseus Blade 140W

TechRadar named the Baseus Blade “one of the best slim yet high output power banks available” — the only one they’ve tested that “can slot into a laptop sleeve, yet still offer fast charging.” At 0.7 inches thick it is approximately 30% thinner than the Anker 737 while matching its 140W PD 3.1 output and 24,000mAh capacity. ChargerLAB tested it charging a 16-inch MacBook Pro M1 Max at up to 130W via MagSafe cable. NotebookCheck confirmed its ultra-slim profile at just 0.7 inches and approximately 490g. For travelers who carry a slim laptop bag rather than a backpack, the Baseus Blade is the only 140W power bank that fits.

📱 Best No-Cable Solution: iWALK LinkPod 4

At approximately 65 grams — lighter than a set of keys — the iWALK LinkPod 4 is the most portable power bank on this list by a significant margin. The built-in USB-C plug eliminates the need for a cable entirely: plug directly into your iPhone 15/16 or USB-C Android and charge on the go. 4,500mAh provides approximately one full iPhone charge. 20W output delivers meaningful speed for a pocket-sized emergency charger. iWALK confirmed it recharges itself fully in approximately 1.5–2 hours via a PD charger. For anyone who has forgotten their power bank cable and been stranded — the LinkPod 4 solves that problem permanently.

Anker 737 PowerCore 26K

Best for: Business travelers, digital nomads, content creators and anyone who relies on a laptop away from a power outlet for extended periods. The Anker 737 is the right choice when you need 140W laptop charging power with maximum capacity in a TSA-compliant form factor. Note: at 630g it is not a pocket power bank — it belongs in a bag alongside a laptop. If you primarily charge phones rather than laptops, the Anker 622 or iWALK LinkPod 4 are more appropriate options at a fraction of the weight and price.

The Anker 737 PowerCore 24K is the benchmark for high-output TSA-compliant power banks in 2026. StorageReview confirmed it “delivers an impressive 140W to your devices” via Power Delivery 3.1 — the latest USB-C standard, which enables higher voltage charging (up to 28V) required to charge large laptops at their maximum rated speed. The practical result: a 16-inch MacBook Pro reaches 50% charge in approximately 40 minutes from a flat battery. WorldTimesNow’s 2026 review confirmed it as “arguably the best tech investment you can make in 2026” for anyone relying on a laptop away from outlets, calling it “a portable power plant” that gives “the freedom to work from anywhere — a park, a plane, or a bus — without anxiety.”

The OLED display is the feature that most clearly separates the Anker 737 from budget power banks. Rather than ambiguous LED dots, the OLED screen shows real-time input and output wattage, estimated time remaining at current drain and charge cycle count — giving you precise information about exactly how much runtime you have left and how fast your devices are charging. Anker’s blog confirmed it as “the sweet-spot brick: 24,000mAh in a 22 oz chassis about the size of a TV remote” with “two USB-C jacks that deliver — and accept — up to 140W of PD 3.1 power.” Self-recharge takes approximately one hour with a 140W wall charger — though Anker does not include a wall charger in the box, which is the primary complaint from reviewers. The 86.4Wh capacity is specifically engineered to sit just under the 100Wh TSA carry-on limit, so it flies on every commercial airline without issue. A 140W USB-C cable and travel pouch are included. 24-month warranty standard. Note: this model replaced the original 26K (discontinued July 2025) — the current PowerCore 24K has the same core profile with a slight capacity adjustment to the current 24,000mAh/86.4Wh specification.

Baseus Blade 140W Power Bank

Best for: Travelers who carry a slim laptop bag or briefcase rather than a backpack and need 140W laptop charging power in the thinnest possible form factor. The Baseus Blade’s 0.7-inch profile allows it to slide into a laptop sleeve alongside the laptop itself — something the Anker 737 cannot do. The right choice if you prioritise thin-and-light carry over having an OLED display, and want to save money versus the Anker for identical output power.

The Baseus Blade 140W is the thinnest 140W laptop power bank available in 2026. TechRadar confirmed it as “one of the best slim yet high output power banks available” and the only option they’ve tested that “can slot into a laptop sleeve, yet still offer fast charging.” The spec achievement is significant — matching the Anker 737’s 140W PD 3.1 output and 24,000mAh capacity while being dramatically thinner at 0.7 inches. NotebookCheck confirmed the profile at 0.7 inches (approximately 18mm) and approximately 490g — meaningfully lighter than the Anker 737’s 630g. Macworld’s test of the Blade HD confirmed “charging a 13-inch MacBook Air M1 from zero to 100 percent once with about 5 percent remaining on the blade” — accurate real-world confirmation of usable capacity.

ChargerLab’s detailed electrical test of the Baseus 140W power bank confirmed the USB-C1 port achieved up to 130W charging a 16-inch MacBook Pro M1 Max with a MagSafe cable — real-world performance very close to the 140W maximum. The same test confirmed self-recharge in approximately 1 hour and 6 minutes using a 140W charger. The drop-shaped LED display shows remaining battery percentage, voltage and current — less detailed than the Anker’s OLED but functional for most users. The matte black PC material exterior is fingerprint-resistant. Two USB-C ports (the second supports up to 100W rather than 140W) and one USB-A port at 22.5W provide three-device simultaneous charging capability, though total output across all ports is shared. Pass-through charging works — you can charge the power bank and output to devices simultaneously. 24-month warranty. The primary limitation versus the Anker 737 is the display — it provides less detailed real-time charging information. For users who want to see exact output wattage and time remaining, the Anker’s OLED is worth the extra cost.

Anker 622 Magnetic Battery (MagGo)

Best for: iPhone 12 and later users who want a cable-free power bank that magnetically snaps onto the back of their phone, doubles as a phone stand via the foldable kickstand, and fits in a pocket alongside the phone. The Anker 622 is not for laptop charging — it is specifically designed for the iPhone user who wants 7.5W MagSafe top-up without carrying a cable. Not compatible with Android unless used with the USB-C port.

The Anker 622 MagGo is iMore’s recommended MagSafe power bank, confirmed as “perhaps the best MagSafe battery pack so far” at the time of launch. iMore specifically highlighted the magnetic attachment strength: “the magnets in Anker’s power bank are strong, meaning that you won’t have any issues with the charger falling off the back of your phone, even when getting it in or out of a pocket.” Independent testing at jcintheshed.com confirmed the 622 MagGo holds securely on a Samsung Galaxy S23 Ultra — one of the heaviest phones available — without slipping. The magnetic connection strength is the most practically important spec on a MagSafe bank, and the 622 passes.

The 7.5W MagSafe charging speed is the maximum Apple allows for third-party MagSafe accessories on iPhone — faster than the 5W of most wireless chargers and on par with Apple’s own first-party MagSafe Battery Pack for wireless output. Macworld’s test found the Anker 622 charged an iPhone 13 Pro from 5% to 85% before exhausting the 5,000mAh capacity — an 80% net charge delivery accounting for wireless inefficiency losses. The foldable kickstand is the feature that makes the 622 genuinely useful beyond pure charging — it holds the iPhone securely in both portrait and landscape orientations for video watching, FaceTime calls and desk use. The USB-C port on the bottom charges non-MagSafe devices via cable and recharges the power bank itself. The one limitation: you cannot use the wireless output and the USB-C output simultaneously to charge two devices at once. At 149g it is light enough to carry in the same pocket as the phone. Available in five colours. Compatible with iPhone 12 through 16 series and any phone with a MagSafe-compatible case.

iWALK LinkPod 4 Pocket Charger

Best for: Anyone who wants the absolute minimum power bank — light enough to forget it’s in your pocket, small enough to fit anywhere, requiring zero cables. The iWALK LinkPod 4 is the emergency charger for people who leave their main power bank at home, the travel companion for minimalists who count every gram and the solution for the specific frustration of having a power bank but no cable to connect it. At approximately $25–30 it is also the most affordable option on this list by a wide margin.

The iWALK LinkPod 4 solves one specific problem better than any other power bank on this list: it requires no cable at all. The built-in USB-C plug extends directly from the bottom of the charger and plugs straight into any USB-C device — iPhone 15/16, modern Android phones, AirPods, earbuds — without reaching for a cable. iWALK’s own product description confirms it as “ultra-compact, wire-free, fitting easily into your pocket or bag — perfect for travel and on-the-go charging.” At approximately 65 grams it is lighter than most smartphones and dramatically lighter than any other power bank on this list. The lipstick-sized form factor means it disappears into a jacket pocket, small handbag or AirPods case pocket.

The 20W USB-C PD output delivers genuine fast charging speed for smartphones — iWALK confirmed it fast charges an iPhone from 0% to 50% in approximately 30 minutes. The 4,500mAh capacity provides approximately one full charge for an iPhone 15 or similarly sized phone. Pass-through charging allows you to plug the LinkPod 4 directly into a wall outlet while your phone is connected — the power bank charges itself and your phone simultaneously, eliminating the need to carry a separate charger for the power bank. iWALK confirmed self-recharge in approximately 1.5–2 hours via a compatible PD charger. The honest limitation is capacity — 4,500mAh is a single phone charge, not multiple. For multi-day travel or laptop charging, the Anker 737 or Baseus Blade are the correct choices. The LinkPod 4 is designed for daily emergency backup and minimalist travel, not extended power independence. Available in multiple pastel and neutral colours at approximately $25–30 — by far the most affordable option on this list.
