Good rest and a light pack are both essential in backpack journeys. FLEXTAIL managed to make their ZERO PUMP the lightest and smallest outdoor pump. It is smaller than a Snickers!
Combining patented AIRVORTECH™ Technology 2.0 with an exclusive micro-motor, ZERO PUMP reduces the size of the unit while maintaining superior performance. It can inflate a sleeping pad in just 50 seconds, and inflate up to 25 sleeping pads in a row. Simply connect ZERO PUMP to your sleeping pad and double-click. You don't have to hold it in your hands! With 6 included multi-purpose nozzles, ZERO PUMP is compatible with most brands. Exclusive soft rubber nozzles can be tightly connected to inflated products, which prevents sleeping pad air leakage problems.
ZERO PUMP can be used to deflate your sleeping pads for efficient packing as well. A simple finger press will allow the air to escape properly and quickly. ZERO PUMP can also be used as an fire-starting tool to helps build a quick flame.

Bit frustrated
Looks and works great, except for the fact that my battery cap got stuck (on day one) and I had to use WD-40 and pliers to get it of

Lightweight, works great, long battery life
I do a lot of winter trips and wanted to avoid warm moist air in my sleeping pad. I have found that the battery lasts me for 14 uses before totally running out. About 2.5 minutes/day.


Not powerful enough & noisy
Personally, I found the air-pump didn’t really have enough power to make my sea-to-summit mattress firm enough. I still had to use the bag to finish the job. I also found the motor to be very loud and off-putting. Personally, I’d say it’s one of those sounds that doesn’t belong in nature.
