Lots of 12v pumps available very cheaply from places like Aldi but are they any use for inflating a tender, or are they just suitable for beach toys.

I doubt that they will manage the necessary pressures. Our airdeck needs 0.6 bar and the piston pump kicks in at under 0.2bar. I think that these pumps are just turbines, so will probably only reach 0.1 bar which isn't high enough for the side tubes. Our pump is made by Bravo, expensive, but excellent.

use the foot pump for the last 5% of air to get pressure
 
You might find that pump doesn't generate enough pressure to overcome the valve seal on a dinghy.
I've used Bravo pumps in the past, as mentioned above pricey - but good quality.
Just a thought - why not check out what the iSUP folks use? Their pumps need to go to 15/20 PSI and move plenty of volume. A very quick search shows one for £50 from Decathlon - i'm thinking of getting one of those myself now ?

I use a cheap pump exactly like the one shown to inflate my Honwave. It does most of the work. Finish off with the foot pump. Saves most of the effort for very little cost. I use the foot pump hose, which has the correct bayonet fitting for the tender, pushed onto a short length of hose which fits the threaded end of the foot pump hose and the electric pump. Takes seconds to connect.

I have exactly that Aldi pump - both the 12v and 240v versions and both are lasting very well (5+ years). Quickly inflates my paddle board and my Zodiac 2.6m inflatable. Noisy but no complaints - would highly recommend for the price

I know its not cheap but I bought one of these, my god its good. We use it to pump up two paddleboards to 20PSI and a kayak.

It runs at low pressure first than switches to high pressure when needs be. You just dial in the required PSI and go put your wetsuit on :)

I've been looking at these but don't want to disturb people when heading out to the mooring late at night.. how noisy are they?

The low pressure compressor is ok but as soon as it moves over to the high pressure its embarrassingly loud. I use it inside my van which muffles it and makes it ok but you don't want to stand inside with it on......
I don't think a dinghy would need the high pressure compressor side though so it might be ok, I can't remember at what point it switches over but can check next time if you like.

a normal car one which fits into the cigar lighter with a suitably modified end for the dingy , easy . (y)

?? What the ones that pump up the car tyres ? They are High Pressure but very low volume.

I have a couple of cheap 12v airbed pumps - high volume, low pressure ... and they do my Avon Redstart and the 'Chinese' similar dinghy --- with only a few strokes of foot bellows to finish off.
 
A decent turbine type gets 'good enough' pressure for a dinghy. I bought one from a member on here via the for sale section. Unfortunately he'd bodged a hidden repair and it died after one use. He knows who he is.

I tried to buy the Decathlon one last year but they were out of stock, so I'd like to hear how @Moodysailor gets on with his.

yes (y) ( i am not saying they are the only method, just one viable one )

Well thanks for the advice and opinions.

I think a cheap centrifugal type and a little healthy exercise with a foot pump should do the biz!

I'm one of the laziest when it comes to this sort of thing .. and the cheap pump + a few minutes with foot pump suits me fine ...

Certainly better for my pocket as well when I see the daft prices for 'Marine' 12v inflators !!
 
I have used one of the cheap ones for several years. Plug in, let it run, go and do something else. Blows up my dinghy to 80% finish it off with manual pump.

I subsequently bought a Coleman 12V which seems better but have not used it in anger, they also do a rechargeable one. When I blew up the dinghy at home last week it got to a pressure that probably could be used fairly quickly, I then finished off manually.
 
Coleman 12v quickpump. works off its internal lead acid battery. Inflates and deflates. Noisy as h**l. Gets the pressure up to where 1 or 2 strokes of the foot pump finishes the job. No cables so use anywhere on the boat. About £35. Wouldn’t be without it
 
Not electric but I bought a decathlon manual SUP pump to replace my Bravo. It's half the price has a pressure gauge and seems to work well.
