Wen 3800 vs Predator 3500 – How do they compare


The Wen 3800 offers more power output than the predator 3500. It has a running and starting watts capacity of 3400w and 3800w compared to the predator 3500 3000w and 3500w respectively. The extra power is vital if you have multiple appliances that you want to operate. The generators have similar run times with the predator 3500 being able to operate for 11 hours at 25% load capacity. The Wen 3800 has a run time of 8.5 hours at 50% load capacity. Both generators are parallel compatible meaning you can connect them to a similar generator for more power output.

Fuel capacity and noise levels

The predator 3500 has a slightly larger 2.6 gallon tank compared to 2.2 gallon for the Wen 3800. However, the fuel consumption is similar at 0.26GPH. The generators have the same noise level output of 57dBA. They also have relatively low THD with the Wen 3800 coming in at <1.2% while the predator has <5%.


Both generators weight the same so none is better in terms of portability. The generators weight 99.2lbs and also come with transport wheels for easier movement. The handles are different with the Wen having a folding handle while the predator comes with a double handle. You can also start the generators either via an electric starter or a pull and start mechanism. Both generators feature 3 AC outlets and do not come with GFCI outlet. The generators also come with digital data centers and built-in fuel gauge.
