12v Electric pump to deflate Sea2Summit Mattress SIM?

[a892374923874]

Our Sea2Summit mattress can fit in the bag with sheet and protector left fitted. But only if we deflate it using a mains powered vacumn cleaner.

I've tried using an Outdoormaster 2 stage SUP/Kayak pump in deflate mode, but the 1st stage is not powerful enough, and when the 2nd stage kicks in, it does not suck air through the deflate port.

Has anyone come across a 12v pump that has a decent suck on the deflate port?

Cheers

I use a Shark 2 to deflate the air awning, but I have not tested the 2nd stage though, I'll let you know.
