Performance
At 142 L/min airflow and built-in pressure control (5 kPa inflate, 10 kPa deflate), it pumps a MegaMat in seconds and completely deflates it within a minute (). The dual-click power interface is simple, the USB‑C recharge takes ~5 hrs, and the unit runs for ~25 min—enough for multiple mats [oai_citation:0‡EXPED USA](https://www.expedusa.com/products/mega-pump?srsltid=AfmBOopKW6KDZnGQZjOxVIMXPt1zBrmHAgX-nJRLG2AjB8IGquP7ZE1f&utm_source=chatgpt.com).

Final Thoughts
The Mega Pump is a game-changer for car campers and basecamp setups—no breath bank needed. If you're inflating large mats like the MegaMat or multi-person gear, this is a smart upgrade. Perfect balance of speed, portability, and power, though expect some noise and occasional recharges on long trips. For ultralight backpackers, it’s a luxury—but for comfort setups, it's a must-have tool.
