Makita & Dewalt also have compressors, more traditional shaped.
Probably not as portable as the one above, but one gets easily replaceable batteries, and should have a lot of power.
Good thoughts. Although for me, I'm interested mainly for the portability, so that Xiaomi one still looks like a reasonable compromise. If I'm running around all day, I often have a battery handy to recharge my phone, so it'd be nice if it could do double duty by running a small compressor, but failing that, the integrated battery approach is workable. Although since I can't use my cache battery for the pump, it'd be nice if I could use the pump battery to recharge my phone. Still, the more I think about it, the more I like this idea.
