Bluetti Apex 300 Review (2026)
A 240V home backup unit that also plugs straight into a 30A RV hookup.
The Short Version
If your well pump or the 240V loads behind a transfer switch draw under 3,840W, we’d start with the Apex 300. The Anker SOLIX F3800 Plus does that job for roughly 70 percent more, and the EcoFlow DELTA Pro 3 for nearly twice the price.
It weighs about 84 lb, twice the Jackery HomePower 2000 Plus v2, and has no USB ports until you add Bluetti’s Hub D1.
A full charge keeps a 100 to 150W fridge going for 14 to 19.5 hours, and six B300K packs push that past four days.
Buy if
You want 240V for a well pump or a transfer switch without paying F3800 Plus money, or you split the year between the house and an RV with a 30A hookup.
Skip if
Everything you’d back up runs on 120V. Get the Jackery HomePower 2000 Plus v2 for a fridge and sump pump at half the weight, or the Bluetti Elite 400 for 3,840 Wh without add-ons.

What Changed From the AC200PL
The AC200PL it replaces was 120V only; the Apex 300 adds 240V and a 14-50R while keeping the TT-30R. Output rises from 2,400W to 3,840W, and the cycle rating from 3,500 to 6,000. If your AC200PL still covers your loads, keep it until you need 240V or more than 2,400W.
It’s also about 22 lb heavier. B300 packs bought for an AC200PL carry over, while the B210P and B230 aren’t on the Apex 300’s compatible list.
What It Runs, and For How Long
Bluetti’s manual publishes its own runtime formula: capacity times a 95 percent depth of discharge times inverter efficiency, which it puts above 90 percent, divided by the load plus the roughly 20W the unit uses itself. At 90 percent, a full charge gives you about 2,360 Wh to spend.
| Appliance | Typical Draw | Estimated Runtime |
|---|---|---|
| Refrigerator | 100 to 150W avg | 14 to 19.5 hours |
| Fridge, lights, router and devices | 200 to 350W | 6.5 to 10.5 hours |
| Window AC (5,000 BTU) | 500W | about 4.5 hours |
| Sump pump | 800 to 1,200W | 1.9 to 2.9 hours |
| Space heater | 1,500W | about 1.5 hours |
The sump pump row assumes nonstop pumping, and a real pump cycles off between runs. Motors and compressors can start at two to four times their running draw. A 1,000W pump starting at three times its running draw takes 3,000W of the 3,840W on its own.
120V or 240V: What the Switch Changes
The selector is a physical switch, up for 120V and down for 240V, and flipping it cuts AC output, so set it before the storm. In 240V mode each 5-20R drops from 20A to 16A and each pair shares 1,920W, so two 1,500W space heaters on neighboring outlets won’t both run. The TT-30R falls to 16A as well.
Leave a house setup on 240V. It’s the only mode with the 0 ms switchover, on the two left-hand outlets while the unit charges from its 15A cable. Every other outlet switches in up to 20 ms. For RV trips, flip to 120V so the TT-30R gets its full 3,600W.
Charging
The included cable plugs into an ordinary 15A outlet and tops out at 1,800W, split between refilling the battery and powering your loads. It ships set to 12A, which you can raise in the app.
To reach 80 percent in about 45 minutes at 77°F, charge through the P050A port instead. It takes 120V or 240V at up to 30A on Bluetti’s optional TT-30P cable or 50A on its L14-50P cable. Above 15A, put a 60A two-pole breaker upstream and have an electrician confirm the circuit, per Bluetti. We’d only buy the L14-50P cable if you have a 50A outlet or a 240V generator to plug it into.
Solar comes in through two XT60 inputs, 12 to 60V and 1,200W each. Bluetti’s 4,000W solar figure requires its separately sold SolarX 4K controller. From a car’s 12V socket, a full refill takes more than a day.
Hooking It Up at Home
Getting 240V into the house takes an inlet, a transfer switch or panel interlock, and a cord from the 14-50R matched to that inlet, all installed by an electrician.
Keep it indoors and dry, since it’s only rated IP20. It discharges down to -4°F but won’t charge below 32°F. Left in a January garage, it can run on battery with no way to refill.
Adding Batteries
Six B300K packs bring one unit to 19,353.6 Wh, enough by the manual’s formula for about 4 to 5.7 days of a fridge alone. Output stays at 3,840W however many you add.
A stack needs the separately sold P090D cable, one battery type (old B300 packs work, just not mixed with B300Ks) and, once it’s two packs high, metal brackets bolting it to the wall. If 3,840W is the limit you hit, a second Apex 300 on Bluetti’s Hub A1 doubles output to 7,680W.
How It Compares
The Anker SOLIX F3800 Plus is worth the extra money only if the Apex 300’s 3,840W of output won’t cover your loads. It puts out 6,000W from 3,840 Wh and reaches 26,880 Wh on one unit, at about 53 lb more. Its 3,000+ cycle rating is half the Apex 300’s, which matters if you cycle daily on time-of-use rates.
We’d skip the EcoFlow DELTA Pro 3 unless you want 4,096 Wh in the base unit. Its 4,000W is barely above the Apex 300’s 3,840W, and it weighs about 114 lb.
The Bluetti Elite 400 holds 3,840 Wh and costs about 7 percent less than the Apex 300 when bought from Bluetti direct. It’s the better buy if 120V will always be enough and you can live without ever adding a battery.
How We Evaluate Products
We read the specs, warranty and price on October 18, 2026, from Bluetti’s Apex 300 product page and Apex 300 User Manual V1.0, its Product Warranty Period page and the Amazon listing. AC200PL figures come from Bluetti’s published specs for that model. We have not tested this unit hands-on.
