Bicycle Mechanics - Rechargeable compressor that will do my inflateable raft, too?
Bikeforums.net is a forum about nothing but bikes.

Is this an absurdly specific request?
I've got a nice little $30 coleman one for the boat, which takes assorted adapters, but they don't seem to make one for schrader tires. I've been scouring Amazon reviews, trying to find something that will do both, but no luck so far.
Anybody have a recommendation?
Thanks a bunch :)),
What kind of valve does it have?

What sort of pressure does your raft end up at once inflated? I'm asking because a buddy that had an inflatable boat some years back only had to inflate it to around 5 psi to make it hard as a rock. If your raft isn't any different then the matching compressor may be a high volume at low pressure sort of deal that won't fill up a tire past spongy soft.
And certainly the sort of compressor that you would use to fill bike or car tires would be a small volume higher pressure pump that would take about a week to fill a typical inflatable boat.

I think BCRider nailed it. I have a pump for my inflatable boat that is not a compressor, but a fan. High volume, very low pressure. I could pump the boat up with a small 12V compressor which does fine on tires, but I'd probably have to start pumping the boat the night before I intended to use it.

An inexpensive floor pump for the bike. Ones with built in gauge go for $25-$30.

Sounds like you have the Coleman Rechargeable QuickPump. This isn't a compressor and cannot generate the pressure you need for a tire. Compressors will likely not have a regulator that can provide pressure that is safe for an inflatable boat.

As others noted, you need two different devices. High volume/low pressure for the raft & low volume/high pressure for the tires. High volume/low pressure will not do anything for your tires and low volume/high pressure will take too long to fill your raft.
Compressors, like manual bicycle pumps have to be designed around the competing goals of high pressure vs. high volume. A compressor made for a raft or other high volume application probably cannot reach the pressures needed for a bike tire. Conversely a small compressor made for tires, especially for HP bike tires, will be designed as a low volume unit and be very inefficient for filling a raft.
You need to know the application and get a compressor designed for it. Larger compressors, like commercial paint sprayer units, can often do both because they they have enough power available to deliver high pressure ad decent volumes. Check the pressure and volume capacity, measured in cfm (cubic feet/munute) when choosing a compressor. For tires alone very little cfm is needed, but for a raft you'll need more.
What kind of valve does it have?
the raft? i haven't been able to find a name for these valves, but they are a bit under an inch in diameter. i think they may be the same as airbeds. all the pumps i see for them just say 'inflatable raft' when they are listing valve types. it doesn't make the search easier :/.
