Part one of my in-depth review of the Bluetti AC300 portable power station and its B300 battery. I’m breaking my review into several videos to keep the videos relatively short.

In this video, I introduce the AC300 + B300 and review its main features, specs, and what is included regarding hookup cables. I discuss all the input and output ports and product weight and dimensions.

In Part 2, we’ll test its charging and discharging and what the Bluetti AC300 will power in the RV. Stay tuned!

Pt 2 – AC Charging/Discharging & Battery Capacity Tests

I test the B300 battery capacity in this video using a 600W constant draw on the inverter output. Then, I do a maximum AC grid input test up to 3000 watts and a max AC discharge using two space heaters and a heat gun. The AC300 performed remarkably well.

PT 3 – Real-World RV Off Grid Tests

Part 3 of the review contains some real-world winter off-grid testing with my 30-foot Keystone trailer in early December. The test occurs in southern California, down in Death Valley below sea level. First, a discharge test will be done to see how long the battery pack will last with our normal AC and DC loads. Then, a pair of charging tests, a partial sunny day, and a full sun day. I finished with a demo of charging via my 2000W gas generator.

12V/30A Outlet Motor Tests – Landing Jack, Slide-Out & Awning

In this video, I test the AC300 power station 12VDC 30 amp port to see if it can power my Keystone Cougar trailer’s slide-out, awning, and landing jack motors. The short answer is yes. The voltage barely even dropped under load. The 12V 30A outlet has pretty decent regulation.

Part 4 – RV Air Conditioner Test + Pros and Cons

In Part 4, I conclude my review of the Bluetti AC300+B300 power station system. The video starts with a real-world simultaneous charge/discharge test while boondocking in the Arizona desert. It is a warm day, near 80F, so I wanted to run our Furrion 14.5K BTU air conditioner. To extend the Bluetti battery pack’s run time, I’m feeding it around 350 watts of solar energy. Our inside thermostat is set to 72F, and we see how long we can run the AC. The video finishes with my list of pros and cons and final thoughts.

Fair Disclosure: I received a review sample free of charge. I received no money and maintained full editorial control over the video content.

Review Conclusion

The AC300 system is well put together with good power performance specs. Bluetti has addressed many issues I had with previous power stations, such as slow charging speeds, external power packs, and loud fan noise. It’s become a very polished product.

The weight and awkwardness make me lean toward a system of separately wired-in components. I prefer not to have all my eggs in one basket because the RV is our home. But being a full-time RVer in a fifth-wheel trailer, I’m not the target market. The AC300 is more aimed at homeowners or small RV owners.

A van or small motorhome dweller could use this as an easy-to-install, off-grid power solution. Homeowners can use it for backup power and short-term weekend/holiday camping trips. For applications like those, I give it a thumbs up.
