G'day Javier,

It's not directly compatible as the Zempire mats use a larger valve.
Some people do use them though, just manually holding the Widget pump up to the valve, as it has a one way flange, it will inflate.
Hope that helps.

G'day Terry,

So sorry for the delay in getting back to you with this one!
The widget pump isn't suitable for pumping up air swags & tents as they require a higher PSI for structural stabilization.
People commonly use an air compressor with a compatible attachment as an alternative, you just need to be mindful not to over inflate the air tubes.
Hope that helps!

G'day Rob,

We couldn't say for sure as we don't sell the Mountain Designs Comfort 10. They are designed to fit the Exped valves, it looks to be a similar size, it could possibly work if you hold it up against the valve to create a seal.

We dont sell Big Agnes, so cant say for sure sorry!  
I've had a quick look at what i can find of their valves online, and it looks like its abit bigger than the EXPED valves.
If you know anyone who has an EXPED mat or Sea to Summit mat, see if you can compare valve size as that will give you the best indication.

G'day David,

All of the Sea to Summit mats have the same issue with this pump, the valve doesn't quite fit, so it will take some wriggling and adjustments to make it fit and to inflate. You're unlikely to get the right about of pressure into the mat with this pump, so you'd likely need to use the included pump sack to top it off, and get it just right.

G'day Steven,

Its not directly compatible as the valve & pump don't fit together easily, but you can make it work with a bit of wriggling and effort.

Self-inflating mats are really best deflated with your body weight, Kim, we do have a video on how to do it here - https://youtu.be/SvJYkyWdEZ0. I haven't seen a pump specifically deisgned to deflate self-inflating mats, I imagine that because of the resistance of the foam that there aren't many lightweight pumps that would cope without burning out.

You could try a 12V/240V airbed pump, just be wary of how hard it is working. 

G'day Joel,

We've touched on this in another answer, but ultimately yes, with a bit of effort.  The S2S mat valve is the most similar to EXPED, but not identical, so you can carefully work the widget nozzle into the valve.  Its a tight fit, but it can work.

G'day Joe,

Absolutely not, this pump is designed to put a bit of extra air into your self-inflating mats, or to fill up small air beds, in place of blowing them up with your own breath.  Unfortunately its not the right option for air tents.

G'day Emily,

The widget pump is designed to do to up inflates on self-inflating mats, or compact/lighter weight hiking mats.
It wont have the power to effectively pump up a conventional air bed.
If you are wanting a wireless portable pump option, go with the Quickpump Rechargeable.

G'day Mike,

EXPED say the widget will pump a Duo 10 in 4 minutes, 4 times before requiring a recharge.
Its probably fair to say the 15 LXW would get around 6 inflates per charge?  We dont have the exact answer though, so use that as a guide.

G'day Hammer,

Yes, absolutely!
The widget is compatible with the Exped DeepSleep Mat.

G'day Tom,

Not at all I'm sorry mate! The Widget doesn't even come close to the discharge pressure required for a SUP.

G'day Jason,

They are there to offer potential compatibility for other types of valves, but at this stage we're not aware of anyone whos used them.

G'day Shane,

No it doesn't, sorry. We generally would not recommend leaving a mat unattended whilst it being inflated with a powered pump.
There's a much greater risk of permanent damage to the mat.
It doesnt take long, just stick by and keep checking inflation levels with your hand.

*NEED TO CONFIRM IF STILL CORRECT*

*UPDATE 2022*

Yes the Widget comes with a charge indicator, showing the charge level, and changing upon completion.

G'day Lea,

Yes, the Widget Pump and Lantern can operate at the same time.

G'day Will,

It sure is, that's the model Lauren uses in the video demo of the Widget.

G'day Chris,

It sure is, Lauren uses the Symat 9LW in the demo video!

G'day George,

Yes, the Widget Inflation Pump is compatible with the Megamat Duo 10LW

G'day Steve,

No, the EXPED Widget does not have a deflate function or inflation modes.  It is just click on and off.

G'day Michael,

No, the EXPED Widget is designed to be used with EXPED Flat Valves only.
They can be used with some Sea to Summit Mats with a bit of effort as that's the only other similar valve, but there is no compatibility with other brands.

Thanks for the tip Josh!
