Review: Exped Mega Pump

Blowing up a mattress by hand—or rather, mouth—isn't exactly a big deal, but when it's a large mattress, or you've already given yourself a head-rush on that beat-up old Therm-a-Rest from high school, the Exped Mega Pump can help you breathe easier. Battery-operated, this hand-sized workhorse whizzes like a mini-cyclone, filling your Exped mattress in seconds. I use it for topping off, too, as it gets harder to blow as the pressure increases. Where the pump really shines, though, is deflation—simply flip the device around and suck all the air out of your pad, allowing for easy roll-up and stowage. The Mega Pump includes adapters for use with non-Exped mats, and charges quickly with the included USB-C adapter. $64; expedusa.com.
