- Ultra-Lightweight Design: At just 5g (0.18oz), the KIN PUMP is the lightest air pump available—engineered for ultralight backpackers, thru-hikers, and minimalists who count every gram. This tiny 3D-printed tool doesn’t aim to compete with full-sized electric pumps, but to give you just enough power to make camp setup easier after a long day. It inflates about 95% of your sleeping pad in just 60 seconds, leaving only 1–3 breaths for final adjustment to your preferred firmness.
- High Compatibility: KIN PUMP is compatible with a wide range of popular sleeping pads, including Therm-A-Rest, Sea to Summit, NEMO, Rab, EXPED, Big Agnes, and Decathlon. No matter which brand of sleeping pad you use, the KIN PUMP has you covered.
- Energy Efficient: Powered by USB-C, the KIN PUMP can be charged with your phone’s USB-C cable. With a 10,000mAh power bank, it can inflate a standard sleeping pad over 500 times, consuming less than 0.2% of the battery each time. This makes it an incredibly efficient choice for long trips.
- Dual-Speed Airflow: The KIN PUMP features two speed settings: the low-speed mode (53dB) for a quieter inflation and the high-speed mode (75dB) for faster inflation. In high-speed mode, it can fully inflate a sleeping pad in just 60 seconds, while low-speed mode takes about twice as long but is much quieter.
- The KIN PUMP is ideal for hikers who wouldn’t normally carry any inflator at all. If you already use larger, high-output pumps and expect the same performance, this isn't meant to replace those. But if you're looking for the lightest way to remove the hardest part of inflating a pad, KIN PUMP delivers exactly what you need—and nothing you don’t.
