FLEXTAILGEARBattery-powered Tropo 2 Portable Electric Tiny Air Pump Quick Backpacking Small Inflator Deflator for Air Bed Mattress, Sleeping Pad, Swimming Ring, Pool Inflatables, Vacuum Bags (White)

I use it modified for vaccuming ant ouside world ! Works well !

This little thing is awesome. It feels solid and does what it is designed to do. I like how to takes AA batteries so no need to worry about an internal battery. I got it because apparently you’re not supposed to breathe into an air mattress in the winter because the water vapor freezes inside the pad and reduces the R value so no need to worry about that anymore. This thing is also small so it takes up almost no space in my backpack. It comes with different types of nozzles for different valves but so far I’ve only used it on my thermarest pad and it does great.

does a great job

I thought it to inflate my travel foot cushion for my long haul flights and it is easy to use

I agree with the review by C on August 28, 2022 regarding weight for backpacking. The weight listed here is without the batteries. When you add batteries, ~237 grams. The cube shape is also a little bulky if you're trying to be as light and compact as possible.I plan to upgrade to Flextail's tiny version that has the built in battery. The weight on that one includes the battery.Flextail should make these weight differences more clear by including the weight of batteries on this model. I originally went with this one because it appeared to only be a little heavier but $20 cheaper than their lighter version. They are not doing their lighter version justice.I also did originally like the idea of AA batteries here so I could swap if I ran out. But I've never needed to on a typical camping trip. And even if I did, I use a battery bank for my phone, and their upgraded version has USB-C plug to recharge that I could use.If backpacking, skip this one and get their smallest lightest version to spare yourself a future upgrade.
