70Hz is likely a typo in the specifications. Given this is a Chinese built generator the typo is the least of your worries. There is a reason the generator is inexpensive, er, cheap. I'd suggest you keep looking.

Most devices will work ok with 70Hz AC. The problem usually happens with transformer operated devices when lowering the frequency. Most items are designed for operation between 50Hz and 60Hz. Increasing to 70Hz will cause motors to turn faster, but otherwise should have little other negative effect.

The engine speed is controlled by a centrifugal wheel connected to the crank. The wheel has levers that push backwards against the throttle. Adjusting spring tension against the lever will allow the engine to operate at 3600RPM, ie 60Hz. Under no load, most portable generators are set at 62Hz output, 3720RPM. When loaded the speed will reduce slightly to 60Hz.

Read through my generator pages and click the various links for more information.

It depends on what equipment you're running with it. You never know until you hook it up, but you'll have to check EVERYTHING. That includes circuitry in your house that you may not be aware of, such as doorbell transformers. This won't harm computers or anything with a switching power supply, but line frequency transformers, motors, and conventional fluorescent lamp ballasts will be affected. The thing to watch for is overheating. You'll begin to notice an odd smell and the equipment will be too hot to touch. I tend to think that in most cases, though, you will run into the problem of not getting as much power. This is because as the frequency increases, inductors pass less current.

most likely not, there are ALOT of generators that dont produce 60hz, unless they are inverter type generators, now the thing is, alot of times with electric appliances the standard is + or - 10% of rated, that gives you a considerable area of flexibility, so do the math and see where you end up, and always remember you get what you pay for, a cheap generator will probably produce whats called dirty power, not balanced and erratic, if using it I would probably use the bare essentials and nothing more. If your planning on running your 60" plasma i would say hell no.

Could be a silly question but who uses 70Hz?

If this is a gas powered generator can you not just adjust the governor to slow the engine slightly?

In any case, I doubt that 70 Hz would do much damage to your equipment/appliances.

Hard to say. Some transformers will run hotter when fed a higher frequency power.

Of greater concern is waveshape. Unless it's a "true sine wave" generator, I wouldn't use it on anything electronic, like a TV.

Who makes a 70 Hz generator? Please provide a name or a link. This is really almost too weird.

Don't do it. Quit trying to save that all mighty dollar by buying something that is not rated at what people need on a regular basis. This will damage equipment and appliances and cost you more in the long run,

70 hz will burn any thing out, that requires 60 hz

its the cycling of the electrical, flow,

that is why its so cheap!! its useless for everyday applications,,,,, it will ruin most everything
