exploding avon redcrest

[Burst Boiler]

I've been enjoying the resurrected thread on TOP on blowing up a dinghy, and the Webby/Claymore banter from 2 decades ago. I spent some time last summer trying to turn cheap chardonnay into champagne using a sodastream. The result was horrendous, but would a sodastream bottle have enough gas to at least part-inflate a flubber, but not so much to burst it?

The short answer is no. Cartridges of CO2 the I have seen hold a few grams of compressed gas. By my estimation it would take somewhere in the region of over a kilogram of CO2 to inflate a Redcrest.

Agree with Ken above. A soda stream cannister holds around 60 litres of gas at 1bar, a back of envelope calculation of the volume of a 2.9m dighy tube volume is around 800 litres. So a soda stream canister won't even get it floppy. The inflation cannister on a liferaft is pretty heavy.

Bought one of these to inflate our SUP’s and Wingfoil boards. Tried it out yesterday onboard with the wee Q-lite dinghy.

Very impressed by how fast and easy it was.

Miles better than the crappy foot pump you get with the dink, easier and much faster than the double action Foil board pump. It’ll be perfect if it can charge off the solar panel.

Used the Air Bank again today to sook oot most of the air to make the dink smaller to stuff in the bag. Seems to work fine.

looks like a neat device.
can it be charged on board from your batteries?

[wully]

Yes, it comes with a long 12 volt cigarette lighter plug thing as well as a USB C 240 adapter. You can also run it directly off a 12 volt supply.

Not sure what it would do to your battery bank though….Our minimal load and decent solar panel ‘should’ cope OK.

Could you recharge this from a solar panel? What inputs does it have? Does it have a USB input?

EDIT - I see it has a USB -C input, so we can recharge it from our foldable solar panel

It's gone on the shopping list.

Just bought an airbank based on the above. Arrived today. Brilliant wee thing
Inflated the 2.7m dinghy in just a few minutes. Don’t need much if it’s battery power to do it. Can be recharged on board from the 12v sockets

I had to send the Air Bank back…. It would not hold a charge for more than a couple of days..

Are you sure you were getting it fully charged?

[wully]

Yes it was fully charged after it died each time. It appears to been a common fault with that brand.

I bought a normal 12 volt plug in one as blowing up a couple of 12.5 ft SUP’s a wing foil board and a wing by hand needs a wee lay down and a snooze before I can go in the water…

Take 1 pot vaseline petroleum jelly or similar
(Can you see where this is going yet)
Attach inflation tube to SUP
Adopt the position
Apply Vaseline (or similar) to inflation mechanism
Insert inflation tube
Breath out through yer inflation mechanism
Be careful not to over inflate SUP

not used my one v much, but after charging and leaving for a few days/week, its still showing charged and works OK.
Was your one showing as charged when it actually wasn't, or was the charge indicator also showing it had discharged?

[wully]

The charge indicator worked, showed full when charged and MPT when deed..which was about overnight sitting in its case..
