As the 75537i and the 75531i are both Champion generators, they benefit from the same level of quality and attention to detail.
Power Comparison
The following charts are provided to show you at a glance how the main specs of the Champion 75537i compare to the Champion 75531i.
- Power: As both the Champion 75537i and the Champion 75531i share the same running wattage of 2,800W, they will both allow you to simultaneously power the same appliances. In addition, as the 2 generators have the same starting watts (3,100 W), they will both give you the same boost needed to start the motor of your most demanding appliances.
- Runtime: At a 25% load, these 2 portable generators offer the same runtime on a full tank. Each of them will be able to deliver power for up to 8 hours.
- Fuel Efficiency: At the same load as mentioned above (i.e. 25%), both generators will approximately burn 0.2 gallon of gasoline per hour. Inverter generators like these 2 are of the most fuel efficient (and quiet) type.
- THD: Both generators offer a low THD (<3% for the Champion 75537i and <3% for the Champion 75531i) and are therefore perfectly suitable to safely power your sensitive electronic devices.
- Noise: Both devices have a noise rating (lower limit) of 58 dBA. If noise is important to you, neither of them will be easier on your ears.
Portability Comparison
- Bulkiness: When compared, the Champion 75531i and its dimensions of L22.4" x W17.3" x H18.3" offer a slightly more compact experience than the L25.1" x W17.3" x H18.3" of the Champion 75537i.
- Weight: The 75531i and its 83.8 lbs is somewhat lighter than the 96.6 lbs of the 75537i.
- Portability: Both products benefit from a set of wheels, which greatly enhances their maneuverability. Both offer a folding handle, which improves your grip when you wish to move them around.
Feature Comparison
- Starting System: These two devices can both be reliably started thanks to a conventional pull-start mechanism. However, the Champion 75537i also benefits from a convenient electric starter. The Champion 75537i offers another layer of convenience, as it can be remotely started.
- Outlets: The 75537i and the 75531i both offer 3 AC outlets. None of them feature GFCI outlets. Both of them also feature a DC output. In addition, it is worth noting that they both only produce 120V. For more detailed information regarding all their respective receptacles, refer to the 75537i's and the 75531i's product pages.
