honda ex350 generator

Submitted: Saturday, Mar 08, 2008 at 21:12


I've just bought a honda ex350 generator (2 stroke) 2nd hand in great condition. What can I realistically expect expect this generator to power? Will it power a bar fridge, battery charger, lighting (flouros)?? According to the manual specs are rated output 300VA, max 350VA
How much should I have paid for it?

It only has an output of 4 amps at 12v (manual says 6 amp) and am wondering if there is any way to increase this?

Thanks Kc

Can you tell me how much you paid for it, because I have a chance to buy one as well and dont kn ow what to offer.

I only want it to recharge the battery on my caravan via a smartcharger, so it probably suits my needs.

Hi Cruiser

I paid $45 for this one and it is in very good condition. The previous owner has bought a winnebago and is selling all their caravaning and camping gear. I think it is a bargain at that price considering he paid $830 for it according to receipt about 9 -11 years ago. From what i have been able to find on the net it seems this model finished 1999 and from the serial number I think this would be one of the later sales. You can download a manual for it at the Honda website. It starts first pull every time hot or cold and runs very smoothly and pretty quietly. I have so far run 2 x 4ft fluoros (72watt), trailblazer fridge, drill, and grinder (separately that is). It will not start my small bar fridge or run my battery charger. I don't know if it should or not. I have read on 4 seperate sites that fridges prefer pure sine waves and the honda is not. I wonder if the battery charger also requires pure sine wave electricity?? What size and brand smartcharger were you thinking of using?

with less than fifty watts you wont be powering much except charging batteries. A reasonable drill starts at about 500 watts. One four foot fluro takes forty watts.

12 volt waeco type fridge takes nearly four amps when it runs.

Definately not worth buying an invertor for it but yeah its a great backup for the battery.

There is good info here on this site under electrics.

Hi Owen

I believe it puts out 300 watts @240 volt. On 12 volt it is rated at 6 amp but I could only measure 4 amp with multimeter when connected to a battery being recharged.... but then again the battery was close to full charge.

Hi Bruce

what type of battery charger did you use. I found when I hook up mine the charger can only put about 1.5 amps into the battery but when the same charger is connected to 240 volts that increases to 4 or 5 amps. Any idea why this would be so? Also it will not start my bar fridge which uses 50 watts continuous and about 180 watts at startup according to my power meter. I wonder if this is because fridges prefer pure sine electricity which the generator does not provide or am I not getting an accurate startup wattage reading from my meter.

thanks Kc

My brother recently gave me a Honda ex350, and although we haven't put it to the test yet, it seems to run fine. I've just played around at home with it with lights etc. We'll be putting it to the test this Winter when, after fishing & crabbing at Groper Ck., we'll be heading to Rubyvale to camp out on the gemfields for a few weeks. I only intend to use it as a battery charger cum back up. Cheers.

Hi, Kc , Just a few "facts" on the Honda EX 350. I have had one for 14 years and have really tested it out.
It will run 2 Engle friges and a 150w portaflood,( out bush) or 2 portafloods ,
They put out 100 watt DC which will charge your battery Ok , it will put in enough to start a falcon in 10 mins ( flat , no dash lights) ,
But you have to watch that it does not over charge, it will run a small K mart battery charger as well.
we run our's on 50 to 1 mix Stihl chainsaw oil. runs clean and no smoke , will run just on 4 hrs on a tank of fuel ( 0.7ltr from memory) also when finished using ( to store ) always tip out the last of the fuel and then run it on low until it stops , then next time put in fresh fuel and I bet it will start second pull even 6 month later.
I paid $800.00 when I got it , but worth every penny.
You can carry it in side when full of fuel just make sure you lock the cap vent.
Cheers Des.

Hi, I notice some one talking sine waves etc for fridges . we have been using ours every year ( 14) a couple of weeks or more at a time and it has not hurt the Engels. mine is 14 years old and mates is 29 years old.
Also when ( if ) we have a power black out at home I run a light and the sml Tv of it , you cant even hear it running under the back verandah, and it wont worry the next doors either.
I did read of a chap who's battery died out bush and he tied the Honda on the bullbar and ran it to the crook battery and it got him to where he could get a new one.
Cheers Des.

Hi Des
Thanks for the tips.

The pure sine wave was in reference to a small 240 volt bar fridge. Have you ever tried running one from your generator?

thanks Kc

Hi KC , no I have not tried it on my 70ltr bar fridge but when I fire it up June long weekend I will put it on and try it,
I have found it is a lot better to cool the engel down on the power before we go, then it holds it easily.
I reckon it would probabley run the bar fridge if it was already cold.
Cheers Des.

Hi Des

I would be interested to hear how you go. I was talking to the brotherinlaw today who is into electronics and he thinks my electronic power meter (ex Jaycar $39.95) may not be showing the true peak power drawn by the fridge at startup. Does your Kmart battery charger connected to the 240 output put more charge into the battery than the generator DC output which is supposed to put out 6 Amp?
