    1. How Much Power Do I Need?

Add up the wattage of tools, appliances and motors you want to run at the same time. Then select the generator with the RUNNING wattage rating to match or exceed the total load. Keep in mind that tools and appliances with electric motors or heating elements require additional tool/appliance SURGE wattage at startup. Wattage noted below are approximates only; please refer to tool or appliance itself for specific wattage required Amps x Volts = Watts

           * All ratings are estimates. Contact the manufacturer of your item for exact requirements.

           * If your item has a plate on it showing Amps and Volts, multiply Amps x Volts and that equals your Wattage:  Amps x Volt = Watts   

           * If the power requirement you need is not listed, please call us at 1-866-433-9468, we’ll do our best to help determine your wattage needs.

2. Engine Brand?

8. All Elec. Start Generator would come with battery & recoil pull start back up.


9. Digital Inverter Generator & AVR generator.

Most regular generator on the market would be with AVR (automatic voltage regulator) to adjust voltage in +/- 5% base on the load of generator.

All DuroPower Generator have AVR except Digital inverter generator (DP1000i/DP1250i/DP2000i/DP3000Ei) & PMM diesel generator (DP6500ED/EDS, DP7500ED/EDS).

Digital inverter generator would be a high tech generator, we use a digital inverter change AC from alternator to DC then digital control the RPM of the engine base on the load of generator then change from DC to AC again to provide a true sine –super clean power ( +/-3%).

Digital inverter generator have three special things than regular generator:

   1) Super clean power – Voltage: +/-3%, THD < 3%.

   2) Super quiet operation : <58dB.

   3) Super fuel saving: around 50%.

(Base on regular generator with same wattage)

PMM alternator would be a special material called Permanent Magnetic Material (PMM).

This kind of alternator could provide +/- 3% vibration of voltage directly & keep long time no change.


10. Propane Generator / Diesel Generator / Gas Powered generator

                 Base on the same Horse Power of engine, propane powered could Provide 15% less power than gas powered,

                     diesel could  provide 15% more power than gas powered engine.


11. How long could a propane generator run with a 20 Lbs propane tank.

             DuroPower Propane generator line - DP2000LPG/ DP3000LPG/DP3000ELP/DP3800ELP/DP4000ELP/DP5000ELP (Elec. Start)

                    DP6000LPG/DP6000ELP could be easy connect with regular BBQ propane tank (5/10/20/40Lbs…), the kit comes with the  generator no need for any extra tool & part.

                    A full 20 Lbs propane tank could run:

                           DP3000LPG/ELP:  16 Hours at half load/12 hours@ full load.

                           DP6000LPG/ELP:  12 Hours at half load/ 8  hours@ full load.

                     Customer could connect a big tank like 300 Lbs to get longer power.

                     Duropower LP generator could keep continue running for over 300 hours with enough propane.


12. Who would take care your shipment?

     We would use FedEx or UPS ground to ship goods under 150 Lbs like DP4000ER/DP3500E/DP2000S/FP2000i…

        We would use The Customer Global Logistic company to ship over 150 Lbs Like DP9000ER/DP40000EDS/DP5000…

         Regularly should take 6-7 working days to east coast, 3-4 days for west coast for delivery.


13. How to order from Canada.

             We ship our DuroPower products to Canada, but the shipping Cost would be double than US inland delivery.

                    Only UPS Air can take the shipment to Canada & take around four days.

                    Any customer from Canada should provide your zip code & model number first to let us get shipping cost quote from UPS then let you make your finally decision.

                    We do have local dealer in Canada too, cause inventory limited, Please contact us first.


14. How quiet are the generators?

             Regular generator noisy level should be 68-75 dB

                    Quite generator noisy level should be 60-67 dB

                    Super quite generator noisy level should be 55-60 dB


                    Digital inverter generator would be 55-60 dB, sound like a Refreeze start up.                                                         

                    Silent generator would have 60-67 dB, sound like a running car park close you.

                    Regular gas & Diesel & propane generator have 68-75 dB, Sound like stand under a traffic signal light at a cross street.


15. How to read the wattage of generator?

     Surge Wattage would be helpful for your appliances startup together.

        Regularly the generator could keep this wattage in 5 to 10 minute.

        Max Wattage would be important for power more appliances.

        Generator would keep this wattage in half – one hour at least.

        Rated wattage would be good for long term running wattage.

        Regularly, the generator could keep the output over 6 hours.


        For example: DP9000ER would have 9000w surge wattage;

                                                                  8250w max wattage;

                                                                  7800w rated wattage;
