Style: BLUETTI Apex 300+B300K
Purchased this to use in a 5th wheel toyhauler RV. It is a 50amp rig so the Apex 300 is a perfect match. It fits great in the under belly pass through and I plug the camper to it just as if I was hooked to shorepower. Of course not while on the road but I plan to wire an extra connector in the pass through for times that I do need it on the road. It synced up with the app on my phone very smoothly so I'm able to monitor it's status. So far it will power one a/c, a TV, the refrigerator and the converter at once. I'm very pleased with it's performance so far.

Prompt delivery. Love the brand and product. I own a couple of Bluetti products and haven't had any issues with them. Highly recommend this brand.

Arrived on time as described. I bought this system to upgrade the power capacity in my van build. The plug and play system I started out with was a different brand, however I was told bluetti built it. So I was very disappointed that this unit does not have built in 12 volt connections. I had to buy the attachment for that, which can attach to the power system but is awkward to build around. I also had to buy a cord to plug in my solar panels. Even more disappointed that altho the other plugs have locks built in to keep them connected, the cord for solar panels does not. It has disconnected a few times while driving until I put a small piece of electrical tape on the side of the plug. The overall amount of power I now have is why I gave it 4 stars.

This unit is best thought of as two 1920w 120v power stations which can be phase locked to produce 240v which share the same battery. It is a great minimal system to run the whole house ( minus the electric hot water tank). When grid power fails I turn off the main breaker to disconnect from the grid then plug in the Apex 300 into a 14-50 RV outlet and power is restored. With 2 fridges, a chest freezer and normal lights.. etc.. I pull ~850w on each 120v leg of the Apex 300. Luckily my load is pretty balanced on both legs of my circuit box. Remember, for 120v load you have two separate ~1920w inverters. The only way to pull the claimed 3840w from a single device is with a 240v load. I get 4-6 hours with one B300K battery. When the battery gets below 50% I fire up a 3000w generator with the 30a charging cable and can charge at a near twice by discharge rate. In an extended outage I run the generator 25% of the time . You can see the load on each leg in the app. Also, you have to go in advanced mode on the app to up the charging amps to get more than 12a charging from the grid. This is missing in their documentation. I see the Apex 300 as a reasonable minimum setup to run a the whole house. Next step up from running extension cords to a smaller power station in an outage. My solution is still short of having a proper transfer switch.

This beast has so much power. Not as many options as others but the good totally outweighs the lack of usb chargers lol. Yes it is heavy , but I purchased a cart an problem solved. The price is inexpensive. I purchased the bluetti solar4x and solar charging is now incredible.

I bought this Apex 300 and B300k in November 2025. I also own a Bluetti AC200L that I purchased in July 2025. I had to return the Apex 300 due to the inability of the Apex 300 to do what it says it can do. The Specs say that it can handle up to 2400 watts via 2 separate 1200 watt receptacles. The problem is that the Apex 300 has voltage and amperage limitations that prevent the user from doing so. There are no solar panels that can work within the extremely limited range. Currently the highest wattage panel available that has specs within range is 600 watts, but that is only one 600 watt panel per 1200 watt receptacle for a maximum solar input of 1200 watts in this case. They do sell a solar panel kit that will get you 800 watts using both ports, but you would get higher wattage for less money just buying two 600 watt panels. You have to say within a 60v and 20a limit, preventing a series or parallel connection. Other than that it is a good machine. Bluetti handled the return without much issue, although the entire return took around 2 weeks to complete. By the time I had the refund every other product I was considering went off sale and every battery went off sale and many also went out of stock. So I missed out on a couple thousand dollars of savings because of how long the return process took to complete. I had to pay far more money to get a battery, so much that I no longer can afford the power center inverter that is needed to run the system. Now my solar array that would have been up and running for weeks already, is now a distant dream, several months away or more as I have little way to come up with all that extra money needed. I was short by a few thousand dollars once the sales ended on the other products. I am now short by just over $600 for the replacement selections. So keep in mind that while you MAY get a refund (it took significant work to accomplish the return and refund). That is a disappointment as I spent months preparing for those sales and more than a year planning for it financially, just to miss out on all of it due to an incorrectly advertised product. Would I recommend the Apex 300? Maybe... provided you have fuel generators or grid power to charge and that works for you. I would not recommend the Apex 300 if you need solar input for charging due to the limitations. These are great for emergency use but if you are building a solar system to power your home, you might be better off building your own.
