For an expansion, I was hoping that there was a more secure way to stack it like their competitor ecoflow. There’s nothing that allows you to stack it without sliding all over the place. The feet of the expansion battery should connect near the handle area to connect them like Lego blocks.

The Anker battery packs work great. I don’t know if anything better on the market.

Waited a year to catch this on sale to complete my C1000 set up. Worth the wait. Nice to have the peace of mind being that much more prepared for whatever arises.
No space constraints for me, so the connector cable is a non issue. Happy to have back up power when needed.
Thank you Anker for quality products and outstanding customer service!
(And no, I don't work for the company 😄)

Good battery @ At a good price on sale!

It doesn't quite match the listed statistics on the website as far as how long it lasts or how quickly it charges. It is maybe within 70-80% of what they claim.
