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!

Good solar panel
Easy to set up and sturdy carrying case. My only issue: unable to capture more than 300 watts, even in the brightest sunlight.
Hi Dan,
Happy to learn that you're quite pleased with the Solar Panel you've purchased. Solar panels are rated for 22%-25% energy conversion efficiencies, rest assured those are good solar production numbers already.
Decided to pull the plug and get the F3800 and extension battery after Hurricane Beryl. Luckily we haven’t had to use it in an emergency but we’ve done some testing and couldn’t be happier! Great piece of kit, recommend to pair it with a small inverter generator in case there’s limited sunlight.
Thanks for sharing your experience! It’s great to hear that you decided to go for the F3800 and expansion battery and I’m glad your testing went well. It’s always a relief to be prepared, even if you haven’t needed it in an emergency yet! Pairing it with a small inverter generator sounds like a smart move for those cloudy days. If you ever need anything or have more questions, feel free to reach out. Stay prepared and safe!
