Briggs & Stratton Q6500 Review – Conclusion

Briggs & Stratton Q6500 review

To sum it up, the Q6500 from Briggs & Stratton is designed primarily for house backup power needs. It utilizes a transfer switch connected to the twist lock outlet. When connected in this manner, the full capacity of 5000W is available. However, when using an RV adapter in the twist lock, 120V is available through that outlet while the remaining 120V is available through the duplex outlets. Furthermore, being able to access all of its power entirely depends on what you’re trying to run. If the RV is wired for 240V then using a 240 twist lock plug will deliver full power. It should easily run a 15,000 BTU air conditioner. It might not be as a quiet generator as advertised but it’s relatively acceptable due to the huge power this machine is carrying. Also, weighing 128 pounds is not very light but the equipped heavy-duty wheels allow for easy transportation.

Overall, it’s an affordable powerful machine designed primarily for home backup use through its transfer switch. This machine has an incorporated inverter technology you can power your sensitive equipment safely. In addition, a two year limited warranty which shows the trust the manufacturer has for their product. The Briggs & Stratton Q6500 inverter generator review provides the pros and cons of this new edition of portable power sources from Briggs & Stratton.
