G'day David,

Unfortunately, Coleman does not provide anything close to a specification on this one sorry.  There's no info on the pump itself, the cabling or the plug, so we're completely in the dark.  It's going to be an absolutely negligible draw though, the Coleman Rechargeable 12/240v pump draws 0.2A - so this one would be similar or less.

G'day Ross,

I've just measured this for you, the deflate valve is 3cm in diameter.

G'day Tracey,

You can use the 12V inflate all air pump to top up your Exped Megamat if needed, however, just proceed with caution and don't over-inflate it. We'd generally recommend that you use the mini-pump that comes with the mat instead.

G'day Geoff,

The Coleman 12V Inflate All Air Pump will be able to inflate all Coleman Air Mattresses. This unit isn't packed with power, so will take 5-10 mins but it will get the job done.

G'day Margaret,

It does! The side valve is for inflation and the top valve is for deflation.

G'day Imran,

The Coleman 12V Inflate All Air Pump comes with three tapered attachments so it should fit most valves, including a Boston valve.
