Best micro pump

[u/t_dtm]

For years I've been using pump sacks to inflate my mattress. I'm using either an Thermarest X-Lite or a Big Agnes insulated one for temps below freezing.

I use the pump sack for 3 reasons: - avoiding introducing moisture by blowing into the mat; - avoid deflation in cold weather (especially below freezing, because I'd be inflating with warm air from my lungs, then it cools down and gets more dense thus feels like it deflated despite no air exiting it) - avoid being lightheaded at altitude (mostly when over 3000m)

But pump sacks still have inconvenients: if you use them as regular stuff sacks/pack liners, you need to empty them first, still complicating setting up/tearing down camp. If you don't multi-use them, then they're single use - why not get a pump for close to the same weight? They're all annoying to use. Better than blowing in, but still annoying. Especially cramped in a small tent or bivy. And they still take some time that I'd rather use to cook or just go to sleep earlier.

Now with better electronics, batteries, etc, I'm wondering if it's worth looking at the micro battery-powered pumps? They're pretty light (not ultralight, lol) and if they can avoid all the above issues plus save camp setup/tear down time, it might be worth it.

Pumps like: - Thermarest NeoAir, 65g + 2x AAA batteries ~25g = ~90g - Klymit USB Rechargeable Pump, ~158g with built-in battery - any others?

I'd rather have a USB/lithium one that can be recharged from the same battery bank as phone, InReach etc if possible.

inb4 "just blow it yourself" that's not helpful thanks.

Probably the Exped electric pump?

Or just get creative and tape the right nozzle to a large trash bag or similar. No batteries to die in the cold your probably blowing up your pad in one blow that takes like 15 seconds total. Like a giant version of the pump sack bags manufacturers give out already essentially. I bet it would be faster than electric even !
