Hightower, the picture you posted shows a power supply not a charger, in fact it clearly says so on it.
That being the case, it will probably only be supplying power to a basic onboard charging circuit built into the hand held blower itself. It will be this charging circuitry that will control the rate of charge.
You should be able to find a quality branded replacement from somewhere like Maplin or RS (in Hedge End) for next to nothing.

I thought it was just a Nicad Lipo charger, but reading the manual it does Lead acid batteries too. All I need is some leads with 4mm banana plugs at one end and a 5.5mm adaptor in the other and away I go. |
Voltage is too high (11-15V) for your blower which seems to be a 6V nominal system.

This thing is for charging some sort of battery pack, looks like probably something in the 9 to 12 Volt range. DO NOT try to use this on the Coleman pump (which is a 6V, probably Nicad, 4-cell series connected pack.) Voltage is too high, and a 5A capacity will cause some excitement if the overvoltage causes the pack to short.
What is standard AC power in the UK?
US uses 110V, 60Hz. If it's just a freq change (i.e. you guys have 110V 50Hz) just swap the connector. If you use 220, you'll have to use a transformer.

Exactly 
A 240v to 110v transformer...very little cost, no fuss, no risk...and...no bizarre electronic theory and calculation 
Courageous...pass the 
jky...we're 240v in the UK

No 240V is just the peak voltage which it rarely ever is. You're more likely to have a feed of around 220 - 230 volts.

Special delivery of popcorn on the way sir 
Jyaski, I can't be harrised to re-read the OP but I'm sure he said it was lead acid. In any case I think 4 ni-cads will give you a nominal 4.8V anyhow.........

lol , dont mean to throw more fuel onto this electrical fire but actually, 240 is the root mean squared voltage or RMS voltage which is an average. The peak voltage will be higher than 240.

Something about blowers, I think, it was some time ago...
Anyway, UK is 230 v +10%, -6% since harmonisation.

Would a gerbil work just as well or would he need a transformer?

Guess it would depend if it was an African, Asian or Indian gerbil.
