According to WIRED, the right laptop power bank can eliminate the "panicked run to the nearest outlet," and reviewer Simon Hill has tested more than 100 of them over the past few years. For this guide, WIRED focused on models with capacities of 20,000 mAh and up—"enough to charge most laptops twice." The roundup's top picks include EcoFlow's Rapid Pro X, Anker's Prime series, and ReelCharge's ReelPro, with the leading units delivering 300 watts of USB-C power.
EcoFlow Rapid Pro X: 300W, 27,650 mAh
WIRED ranked EcoFlow's Rapid Pro X as the best overall laptop power bank. It delivers 300 watts, which the review says is "close to the maximum capacity allowed on flights." The unit packs 27,650 mAh and offers three USB-C ports (140W, 65W, 65W) plus a retractable USB-C cable (140W), enough to charge a couple of laptops and phones simultaneously. A small display shows remaining power as a percentage and the charging rate per device; it also displays temperature and battery health, and allows brightness and screen-timeout adjustments. The EcoFlow app adds phone connectivity.
The Rapid Pro X supports a broad set of charging protocols: PD3.1, PPS, QC3.0, AFC, Apple2.4A, BC1.2, SCP, FCP, and UFCS. Recharging is fast whether at a wall socket or on the included dock. A single USB-C input at 140 watts fills it in about an hour; using both USB-C inputs reaches 80 percent in under half an hour. The dedicated dock charges via pogo pins at 320 watts, bringing the battery from zero to 80 percent in just 20 minutes, according to WIRED. The package includes the 27,650 mAh model and the charging dock. EcoFlow also sells a 20,000-mAh, 230W Rapid Pro model for $140.

Anker Prime Power Bank: 300W With Optional Dock
Anker's new Prime model in the roundup matches the Rapid Pro X at 300 watts with a 26,250 mAh capacity. It has two USB-C ports and one USB-A port, and WIRED notes it can charge "a couple of MacBooks and a smartphone at once." The power bank features a smart display, app control, and a 3.3-foot USB-C cable. With both USB-C ports connected, recharging runs at 250 watts, hitting 80 percent from zero in 20 minutes.
WIRED says the Anker charging dock is "a little nicer, more affordable than EcoFlow's, and easier to use" with the Prime range. Older Prime models remain available, including a 20,100-mAh version ($150) at 220 watts and a 27,650-mAh version ($150) capped at 250 watts.

ReelCharge ReelPro: Newcomer's Value Entry
ReelCharge appears in WIRED's guide as a "newcomer" with the ReelPro (Model PWB3001). It provides a "generous" 27,000 mAh capacity, a built-in braided USB-C cable, and an informative display with "precise battery stats." The review notes the ReelPro is "a little light on ports," suggesting a compact layout for budget-conscious buyers. Further port details are not provided in the article.
Charging Protocols and Compatibility Notes
WIRED emphasizes that power banks with USB-C ports can charge phones and headphones as well as laptops. The EcoFlow Rapid Pro X's protocol list—PD3.1, PPS, QC3.0, AFC, Apple2.4A, BC1.2, SCP, FCP, UFCS—illustrates the breadth of compatibility that modern high-capacity power banks need to address.
August 2026 Update and Market Context
The review was updated in August 2026, adding power banks from ReelCharge and Pisen while removing older devices and refreshing prices. Warranties on the top EcoFlow and Anker models are two years, reflecting manufacturer confidence in the battery and electronics. The guide also recommends separate roundups for smaller portable chargers, Qi2 and MagSafe power banks, and portable power stations.
