    Why is it impossible to ship this generator to California?

    On July 28, 2019, I placed an order for this generator, and it was delivered to my Northern California house. Never read or heard anything claiming that Californian buyers can't buy it. During a PG&E power outage, it is currently operating and powering the bulk of my home. I'm very glad I bought it!

    Can the eu3000is 1a be compared to another Honda vehicle?


    Please check which is correct since the description reads "Electric start" and others only "Pull start."

    It has an electric start, and the motor's operation charges the battery.

    How to change a battery

    As instructed in the owner's handbook, remove the front cover, detach the battery's connections, remove the battery, and charge it using a battery charger made specifically for 12 volt batteries with 9 amp-hour (YTZ10S) or 11 amp-hour (YTZ14S) capacity. I'd advise carrying out this action each month. The battery died after I let it travel up north and did not recover. I purchased a new battery but neglected to maintain the monthly charge. That battery also failed. After that, I gave up and utilized the pull start. I now own a second 3000i, and I intend to buy a Honda charger/maintainer.
