Both EcoFlow’s Rapid Pro models are on sale right now. The larger 27650 mAh-capacity Rapid Pro X is $170 ($80 off), and the 20,000 mAh Rapid Pro is $70 ($56 off). While both have steadily dropped in price since its release in late 2025 and often go on sale, I have never seen them available for cheaper than this. EcoFlow’s Rapid Pro X can deliver a total of 300 watts to power up a laptop, smartphone, and headphones simultaneously. It comes in just under the maximum capacity allowed on flights.
