EcoFlow RAPID Pro Power Bank (27,650mAh) review

EcoFlow's RAPID Pro packs the most energy on this list into a bank that EcoFlow says stays under the common 100Wh carry-on limit, at 99.54Wh. Total output is 300W across four outputs: a 140W retractable USB-C cable, a 140W USB-C port and two 65W USB-C ports, so a large laptop and three smaller devices can share it. Input is rated at 320W, and EcoFlow says it reaches 80% in 20 minutes on its RAPID Pro 320W charging station. An LCD screen shows power status, the EcoFlow app adds battery optimization settings, and the bank supports pass-through charging. Detachable magnetic cases let you change its look. The downsides are weight and ports: at 699.4 g it is the heaviest pick, and there is no USB-A port. At the $175.99 sale price it undercuts the Anker Prime while matching its 300W rating, and EcoFlow reminds travelers to confirm battery rules with their airline.
