Frequently Asked Questions
Will this power my whole house?
It can power essential appliances but not your entire house simultaneously. You'll need to prioritize which appliances to run. For example: refrigerator + lights + internet + TV, or refrigerator + microwave (one at a time).
Can it run my RV air conditioner?
Yes! The 4000W peak power and 30A TT-30R outlet are specifically designed to handle 13,500 BTU RV air conditioners, which typically require 2800-3000W to start. This is the perfect generator for full RV power needs.
How long will it run my refrigerator?
A typical refrigerator uses 600-800W when running. With Eco mode, the generator can run a refrigerator for 8-9 hours on a single 3.17-gallon (12L) tank, as the fridge cycles on and off.
How quiet is it really?
At 52dB, it's quieter than a normal conversation (60dB). You can use it in residential neighborhoods during power outages without disturbing neighbors, and it meets most campground noise requirements.
What's the difference between this and the 4500W model?
The 4500W has slightly more power (4500W peak vs 4000W) and a larger fuel tank. The 4000W is lighter, more compact, and more affordable while still being powerful enough to run 13,500 BTU RV air conditioners - making it an excellent value choice.
Can I use this indoors during a power outage?
No. Like all gas-powered generators, this must be used outdoors only, at least 20 feet from buildings, due to carbon monoxide emissions. Never use a generator indoors, in a garage, or in any enclosed space.
Does it come with oil?
No, oil is not included. You'll need to add oil before first use. We recommend SAE 10W-30 oil. The oil funnel is included to make this easy.
What does the 30A TT-30R outlet mean?
TT-30R is the standard 30-amp RV outlet type. It allows you to plug your RV power cord directly into the generator without any adapters, making setup quick and easy.
