Excellent product!
[This review was collected as part of a promotion.] I bought this champion expansion battery July 25, 2025. This battery is a great product and does its job by giving more battery life to my champion power station.
Game Changer
[This review was collected as part of a promotion.] This is a game changer for a remote cabin! It has the ability to add units to meet your power needs and charge other equipment! So happy I found this product! Now I don't need to run a generator all the time and waste fuel!
Increased the capcity of my power station by 50%!
We use the battery generator and new expansion pack for backup power since our grid isn't always reliable. Recently, we have begun taking it to trade shows where we are vendors at. In the past, we have to pay $50-$100 per event for electricity! Now, we can put this under our table skirt and put that money back in our pockets! No noise, no gasoline or fuel and plenty of reliable power!
