Bluetti AC300+B300K Review:Power Almost Anything

The traditional portable power solution has long been a gas generator. As effective as they are, they are not without their downsides. These are mainly maintenance, noise, and gas fumes. Subsequently, the meteoric rise of portable power stations and solar generators isn’t surprising. These devices offer a silent, renewable energy solution anywhere in the world. It’s little wonder that off-grid homesteaders and campers have taken to them.

Enter Bluetti’s monstrous AC300+B300K solar generator. It’s a massive power solution for anyone with high energy needs. I’ve been testing this device for over a year. This is everything campers, homesteaders, and preppers need to know about this upgradeable energy solution.

Pros

• Can power almost anything
• Upgradeable
• Tons of ports and outlets
• Can take a ridiculous amount of solar input

Cons

The standard package for this station includes one 2,764-watt-hour B300K lithium-ion phosphate battery. Bluetti made this generator more enticing by making it expandable. Users can add up to four B300Ks for over 11,000 watt-hours of available energy. In short, this device is one of the most powerful Bluetti offers.

Capabilities of the Bluetti AC300+B300K

Whenever I get a new power station, I like to overload it to test its capabilities. In the case of the AC300+B300K, this called for a special test. Since it had an RV-style outlet, I plugged my parents' travel trailer into it. Then, we started running appliances simultaneously to see what it would handle. The Bluetti effortlessly ran the lights, refrigerator, TV, and several appliances, like a high-draw hair dryer and a microwave. To my amazement, it didn’t overload until we flipped on the air conditioner. Unfortunately, the air conditioner had an initial surge that was too much for the unit.

I should note that the test was done with other appliances running. When we turned other appliances off, the air conditioner ran alone. However, air conditioners, heaters, and other heating devices will strain this unit most.

Once I reset the unit, I left the trailer with the lights, refrigerator, TV, and some fans running off the unit. I let it sit all day with these things running to see how fast it drained. It ran for about eight hours before finally dipping under ten percent battery life. I also did a separate test with my Dometic CFX 45 cooler. The Bluetti ran the electric cooler for roughly a week before reaching the same point.

It’s little wonder Bluetti has marketed this unit heavily as a home backup unit. It will keep things running during storms and power outages until the grid is repaired. I didn’t have a large enough solar panel to test the offset; however, I imagine it extends the battery's life further. Thus, this is a legitimate power solution for anyone living off the grid. The possibilities are endless because this unit can be slowly upgraded. I like the idea of getting the base unit to start and then adding more

Downsides of the Bluetti AC300+B300K

The Bluetti AC300+B300K's biggest downside is its portability. The two sections of the unit weigh over 100 pounds combined, so they’re not easy to pick up and move. If it is being used on a homestead or as a home back-up unit, it’s not a big deal. However, it’s probably best to mount it on a cart for anyone wanting something portable for remote work locations.

I’m also not a massive fan of the display screen. The letters and numbers are thin and hard to read, primarily if the unit is outdoors in the sun. Bluetti has started putting better displays on their units since, but this isn’t their best. However, I will note that the touchscreen display works flawlessly.

Final Thoughts on the Bluetti AC300+B300K

Having enough off-grid power is always going to be a challenge. However, the Bluetti AC300+B300K is easily one of the most impressive solutions ever. The fact that it is upgradeable makes it a little more versatile than some of the other power stations available today. This machine is a tremendous silent alternative to a traditional gasoline generator. That makes it ideal for running an RV in a boondocking scenario where one doesn’t want to disturb the neighbors. It’s also a tremendous, centralized power solution for any homestead or work site where the grid isn’t an option. For anyone with massive power needs, the AC300+B300K will likely fit your needs.
