Bongo Fury

Thanks for all the input...............off tomorrow on a 24hr trip to our house in Slovakia, just wanted to be able to make a cuppa at whatever unsociable hour I decided to stop, gonna go for the stainless steel thermos of boiling water!

Stop! Use a glass thermos. Stainless steel ones don't hold the heat so well. Their only advantage is they don't shatter when you drop them.

STOP! Don't listen to Diplomat. A good vacuum stainless steel bottle will hold the heat so well that you can still burn your mouth after 12 hours, unless you buried it in the snow. And it will indeed last a lifetime (and longer).

how about one of these. we have a similar one.....slow but it boils eventually

cheers anna

I am a bit of a novice here, so bear with me....but i am wondering if this is man enough to power a kettle in the bongo, without killing or putting to much strain on the battery?

Let's be clear: no way is the device you linked to any good to power a kettle. Think of the physics here. Watts (energy) = Volts x Amps.

I just made a cuppa while I thought about this and my mains powered kettle is rated at 3000 Watts. OK so it's a bit OTT but it takes say 3 minutes to boil a litre, drawing around 12 Amps. At 150 Watts that's 20 times longer to provide the same energy. Or one hour.

So at +/-12 Volts this thing and the supply wiring will have to sustain at least 10 Amps output for one hour to acheive the same outcome. Your leisure battery might be fine but the wiring to the cigar lighter might be a bit hot by then. Besides, 100Amp/Hour battery fully charged, divided by kettles of water looks like about 6 or 7 if your're lucky!

Inverters for any decent output at 250v need very heavy cables direct to the low voltage input to handle the power.

It's just not worth it. You might be able to heat up mugs of water one at a time but why bother when you could get a camping stove running propane (good when it's cold ) or meths?

Where can I get a good one?

I only use my stainless one when I go canoeing. Fill it early in the morning and by lunchtime it's lost enough heat to spoil the taste of a decent cuppa but still ok for mixing packet soup or pot noodles!

To be fair they are not really as bad as I painted them if kept wrapped in something insulated.
