Note: The B300K can only be charged by connecting to the AC500/AC300/AC200L/AC200MAX.
Power station arrived quickly but I haven't been able to completely check it out because I cannot find the cable necessary to connect it to my B210 expansion battery. Why is this so difficult to find?
Hi David, thanks so much for your review and comments. The battery cable that connects to the power station should be in the package in which the B210 battery arrived. If you need additional assistance, please feel welcome to reach out to us at support@outboundpower.com and we'll be glad to help!

Great add-on for my Bluetti AC200Max
Now, I can recharge faster with this charging enhancer. It allows me to use both solar and AC at the same time resulting in 1,400W instead of just the 900W from solar alone. Also, I can use my regular AC Charger and the Charging Enhancer at the same time on both the main unit as well as the B230 battery. AND, I can use solar on the B230 battery too. Gives me more options to recharge my setup.
We're thrilled to learn this worked out so well for you. Thank you for your review!
I can’t say enough good things about Bill. I had an issue with mine (not his fault) and he sent me a replacement no questions asked. Stand up guy with a stand up business. Cable worked as advertised!
Anker builds solid units. I can charge several devices at once without inverter power consumption. I use this unit when no power is available while I’m on-call. It does what it supposed to do. I would recommend this to a friend.
Thank you for taking the time to share your experience with the Anker SOLIX C300X DC. We're delighted to hear that it's serving you well. Your feedback is particularly valuable for other customers considering this product. We appreciate your business, thank you!
This is a great little work horse when your on the go
