Bluetti Apex 300 Review (2026): 2.76kWh, 120/240V, and a System You Build Around It
Affiliate disclosure: This post may contain affiliate links. No brand pays for placement.
How we evaluated: WildJoule has not bench-tested this unit. Capacity, output, UPS and expansion figures come from BLUETTI’s US product page, checked October 25, 2026. The outlet list, weight and solar input come from a BLUETTI dealer’s spec sheet (Outbound Power). Hands-on observations are Outdoor Life’s and Techspective’s, credited as theirs. Where sources disagree we show both. We couldn’t verify a standalone Amazon listing, so the button goes to BLUETTI.
This Bluetti Apex 300 review covers BLUETTI’s 2,764.8 Wh LiFePO4 home battery: 3,840 W of output with 120 V and 240 V available, a NEMA 14-50R and a TT-30R alongside four 20A outlets, 2,400 W of solar input across two ports, a 0 ms UPS mode, and expansion with up to six batteries per unit. It weighs about 83.8 lb and has no USB or 12 V ports built in. So it’s less a power station and more the core of a home backup system you add to.
Quick verdict
Buy it if you want 240 V from a portable-class unit (well pumps, dryers, an EV trickle-charge, a 50A RV via the 14-50R) and plan to grow it with extra batteries, solar and a transfer panel. Skip it if you want a grab-and-go box. At nearly 84 lb, with USB only through an add-on hub, it isn’t one. A 120 V-only home needs less: the DELTA 3 Max Plus or Jackery HomePower 3000.
Here’s where I stand: I’ve never had an Apex 300, and I haven’t wired one into a house. It caught my attention because it sits right at the point where portable power turns into home backup, and I’ve spent enough years with an unreliable supply to care which side of that line a product is on. This is BLUETTI’s spec sheet, a dealer’s outlet list, and two publications’ hands-on notes. Where they disagree, I’ve said so.
Bluetti Apex 300 review: specs at a glance
| Spec | BLUETTI Apex 300 | What it means |
|---|---|---|
| Capacity | 2,764.8 Wh LiFePO4, 6,000 cycles to 80% | Highest cycle rating in this group |
| AC output | 3,840 W; Power Lifting to 7,680 W (resistive loads); 120/240 V | Techspective lists 3 kW / 6 kW surge, so confirm on the listing |
| Outlets (dealer list) | 4× 20A, 1× TT-30R, 1× NEMA 14-50R (120/240 V) | No L14-30; no USB or DC without the Hub D1 add-on |
| Solar | 2× XT60, 1,200 W each (2,400 W), 12–60 V, 20 A | More solar with BLUETTI’s SolarX 4K add-on |
| AC charging | Standard and silent modes; turbo figures conflict (see below) | Outdoor Life measured about 2 hours to full |
| Expansion | Up to 6 batteries per unit; BLUETTI markets systems of 2.7–100 kWh | Large multi-unit totals need several Apex units |
| UPS | 0 ms mode (20 ms in other modes); 12 kW bypass | Bypass passes grid power through to heavy loads |
| Weight / size / warranty | About 83.8 lb; 20.67 × 12.87 × 12.6 in; 5 years; Wi-Fi + Bluetooth | Wheels or a fixed spot, not a carry |
Why 240 V changes what it can do
Almost every power station under 3 kWh is 120 V only. That rules out the loads people most want during a long outage: a 240 V submersible well pump, an electric dryer, a 240 V mini-split. The Apex 300 has 240 V on a single unit through its 14-50R, per the dealer spec sheet. That’s the main reason to buy it over a bigger 120 V box. Check your well pump’s starting current against our well pump sizing table first. A 1 hp pump’s inrush can be several times its running watts.
Assume about 85% of 2,764.8 Wh is usable, so roughly 2,350 Wh. Our estimates: a 60 W-average fridge runs around 39 hours; fridge, router, lights and a furnace blower together (about 400 W while the blower runs) about 6 hours; a 240 V well pump drawing 1,000 W for 30 minutes a day uses about a fifth of a charge. For a multi-day outage you either add batteries or add solar. Our home battery sizing guide does the full math.
Solar and charging
Two 1,200 W solar inputs (12–60 V, 20 A) make 2,400 W total. That’s more than double most 2 kWh units, and enough to refill the battery in under two hours of strong sun if you have the roof or ground space for 2.4 kW of panels. The 60 V limit per input means you’ll often wire panels in parallel pairs rather than long strings.
AC charging is where the sources don’t line up. BLUETTI advertises very fast turbo charging, and its page quotes “up to 11.5 kW input” for a full system. A standard 120 V/15 A wall outlet can supply only about 1,800 W, though, so the headline turbo figures must rely on 240 V or another high-power source. Outdoor Life measured about two hours to full in its test. Plan on that kind of time from an ordinary outlet, not the marketing number.
Bluetti Apex 300 review: the trade-offs
No USB or 12 V ports. To charge a phone from it you need BLUETTI’s Hub D1 add-on (2× 100 W USB-C, USB-A, car and Anderson ports) or a plain USB wall charger in one of the AC outlets. It’s a deliberate home-backup design, but it surprises people who expect a power station.
App dependence. Outdoor Life reported it couldn’t switch the AC outlets on without the app on its pre-release unit. That may have been fixed in firmware since, but if you hate app-only controls, confirm before buying.
Weight. About 84 lb puts it outside “portable” for most people. It belongs in a garage or utility room, ideally wired to a transfer panel. For the wiring side see our interlock vs transfer switch guide.
Conflicting numbers. Output (3,840 W vs 3 kW), the B300K expansion battery’s capacity (2,764.8 Wh vs 3,072 Wh) and the 14-50R’s rating vary between sources. We’ve used BLUETTI’s figures where it publishes them. Check the listing for anything you depend on.
How it compares
Against the EcoFlow DELTA Pro 3 (4,096 Wh, 4,000 W, 120/240 V), the Apex 300 has less capacity but more solar per unit and the higher cycle rating. Against the Jackery HomePower 3000 (3,072 Wh, 120 V only), the BLUETTI wins on 240 V and solar but loses the built-in USB ports. If you’re weighing a permanent battery wall instead, read whole-home backup vs portable and our whole-home battery backup picks. The wider home backup power guide covers the whole decision.
Where this Bluetti Apex 300 review lands: a smart pick for a house that needs 240 V and will grow into a system, and the wrong pick for anyone who wants to carry their power station.
Frequently asked questions
Does the Bluetti Apex 300 give 240 V?
Yes. BLUETTI lists 120 V/240 V output, and the dealer spec sheet shows a NEMA 14-50R at 120/240 V.
Does the Apex 300 have USB ports?
Not built in. You need the Hub D1 add-on for USB-C, USB-A and 12 V outputs, or a USB charger plugged into an AC outlet.
Can the Apex 300 power a 50 amp RV?
It has a 14-50R, so a 50A RV cord plugs in. Total draw is still limited by the unit’s output, so it can’t supply a full 50A service.
Is this Bluetti Apex 300 review hands-on?
No. It’s built from BLUETTI’s published specs, a dealer spec sheet and other publications’ hands-on reports, each labelled.
