Small Honeywell 800 watt Generator

[RubenZ]

I wonder what you can power with this. It's ultra portable and quiet. If you use Coupon Code: EMCNHHB83 you get free shipping. Anyone know if its a good deal?

[Malco]

Not much power is it. I suppose you could charge your batteries and run lights.

Cheap enough. I see no decibel rating on it. I would be leary for that fact. There dosen't seem to be alot of good reviews on it from what I can see.

Based on the Honeywell Brochure it looks like you would want the 1600watt or 2000watt version.
They indicate that they will charge a 12v battery the 800watt will not.

The single review on the above site indicates the unitis noisier than expected (but who knows what that 1 reviewer expected out of a 4-stroke engine)

[rkswyo]

Here is my take on generators that don't list the decibel rating and are marketed as quiet. Most are not.

[bikendan]

about all that it would be good for, on a RV, would be recharging the battery and powering some lights and water pump.
not enough to run a microwave.
the Honeywell 2000w was a disaster in returns because it had many issues.

RV.net has a huge Honeywell 2000 thread going.
and it was louder than other chinese made inverter generator.

As others have said, I'd be leery of noise with no DB rating.

OTOH, you can run a 25 amp battery charger on about 300-400 watts so an
800 watt genny will easily charge batteries.

FYI,
Power in Watts = Amps times Volts
So 12 volts times 25 amp charger = 300 watts plus normal losses.
That's why I said 300 to 400 watts.

Still that's half the max output on that genny.

Is that a 12v charger or a 120?

I bought a 3600 watt generator at Sams Club. It is not an inverted generator and it isnt as loud as a commercial generator for $320

If you run the A/C - you cant hear it running outside.

I do not plan on using it at a campground because most of the place I camp have Electric and Water - If I decide to run it at a campground I will most likely make some sort of a dog house for it to help reduce the noise

You know I have a 4cycl Weed trimmer that broke at shaft. I wonder how hard it would be to make my own generator. hmmm

Watts don't care.
If you are charging a 12 Volt battery with a charger that has a max output
of 25 amps on the battery side my math is correct.

The charger would appear as a 300-400 watt load on the generator.

The generator would be putting out 120 volts at 300 watts (ignoring
losses) so it would be producing 120 volts at about 2.5 amps.

The charger would be converting the 120 volt AC to 12v DC and both would
still be about 300 watts.

Some generators have 12v outputs but they are typically limited to
10 amps or less.
It's faster and more efficient to use a charger plugged into the AC outlet
on the generator.

I didn't phrase my question right I guess. I was trying to get the math to work right in my head. The way I see it a 25 amp charger would use 120 volts, not the 12 you had stated earlier. So, wouldn't a 25 amp 120v charger be using 3000 watts? not the 300 stated earlier?

Converting Watts to Amps

The conversion of Watts to Amps at fixed voltage is governed by the equation Amps = Watts/Volts

For example 12 watts/12 volts = 1 amp
Converting Amps to Watts

The conversion of Amps to Watts at fixed voltage is governed by the equation Watts = Amps x Volts

For example 1 amp * 110 volts = 110 watts

Converting Watts to Volts

The conversion of Watts to Volts at fixed amperage is governed by the equation Volts = Watts/Amps

For example 100 watts/10 amps = 10 volts

Converting Volts to Watts

The conversion of Volts to Watts at fixed amperage is governed by the equation Watts = Amps x Volts

For example 1.5 amps * 12 volts = 18 watts

Converting Volts to Amps at fixed wattage

The conversion of Volts to Amps if the wattage is known is governed by the equations Amps = Watts/Volts

For example 120 watts/110 volts = 1.09 amps

Converting Amps to Volts at fixed wattage

The conversion of Amps to Volts if the wattage is know is governed by the equation Volts = Watts/Amps

For Example, 48 watts / 12 Amps = 4 Volts

Converting Volts to Amps at a fixed resistance

If you know the volts and the load of the resistance the amps are found by Ohm's law: Amps = Volts / Resistance

Converting Amps to Volts at fixed resistance

If you know the amps and the resistance Ohm's law becomes Volts = Amps * Resistance

RubenZ hook a drill up to that Weed trimmer change the male plug to a female plug and you will get a low wattage genny.

OK you just have to look at it one side at a time....

The OUTPUT of the charger is 12 volts and 25 amps so 12 x 25 = 300 watts.

OR

On the INPUT side of the charger if you increase the volts by 10 times
to 120 volts you DEcrease the amps by the same factor of 10 and the
WATTS stay the same. 120 volts X 2.5 amps still = 300 watts.

The above example totally ignores heat losses in the charger as well as
the fact that a battery is usually charged at around 15 volts but my
statement still stands--

Even the smallest generator can power a 25 AMP OUTPUT battery charger.

The problem usually is the smallest cheapest generators are noisy.
