Frequently Asked Questions (FAQs)
1. What does “inverter” technology do?
Inverter technology converts the raw power generated by the engine into clean, stable AC power (a “pure sine wave”). This is crucial for safely powering modern sensitive electronics like laptops, smartphones, and TVs, which can be damaged by the “dirty” power from traditional generators.
2. How quiet are these small generators?
They are significantly quieter than conventional generators. Models like the AIVOLT and Oxseryn 2500 operate between 57-58 dBA, which is the volume of a normal conversation. This makes them ideal for campgrounds and residential areas where noise restrictions are common.
3. What is a CO sensor and why is it important?
A CO (Carbon Monoxide) sensor is a critical safety feature that monitors the air for dangerous levels of this odorless, colorless gas. If high levels are detected, the generator, like the Oxseryn 2500, will automatically shut down to prevent accidental poisoning. Always operate any generator outdoors and away from windows.
4. What does “parallel capability” mean?
Parallel capability allows you to connect two identical inverter generators together using a special cable. This effectively doubles your available power output, which is useful if you occasionally need to run more demanding appliances, like an RV air conditioner, without buying a single, much larger generator.
5. What is the difference between peak watts and running watts?
Running watts is the continuous power the generator can supply. Peak watts (or starting watts) is the extra boost of power it can provide for a few seconds to start motor-driven appliances like refrigerators or power tools. Always choose a generator based on the total running watts of the items you plan to power simultaneously.
