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!
