BLUETTI calls the Elite 300 “the world’s smallest 3 kWh portable power station,” and its spec sheet backs up the size claim: 3,014.4Wh of LiFePO4 in a 14.4 × 12.0 × 11.7-inch case that weighs about 58 lb. On Oct. 17, 2026, BLUETTI’s U.S. store listed it at $1,199, about 40 cents per watt-hour, with first shipments set for Oct. 23. It has a 2,400W inverter, a TT-30 RV outlet, a 12V/30A port and a 10 ms UPS. There’s one trade-off to know before you buy: BLUETTI says it doesn’t support expansion batteries. This review covers what the Elite 300 can run, how fast it recharges and who it suits best.

Size: why “3 kWh in a 2 kWh body” matters
Most 3kWh portable stations weigh 70 lb or more. BLUETTI lists the Elite 300 at about 58 lb, and its footprint is a little over 14 by 12 inches. That’s light enough for one person to lift into a truck bed or an RV pass-through compartment, though it’s still a two-handed carry. BLUETTI asks for at least 2 inches of clearance behind the unit for its cooling fans, which matters in a tight RV cabinet.
For a sense of scale, BLUETTI’s smaller Elite 200 V2 holds 2,073.6Wh. The Elite 300 adds about 940Wh, roughly another night of a refrigerator, in a body BLUETTI describes as no bigger than a 2kWh unit.
What it can run (estimates)
BLUETTI’s FAQ gives a runtime formula: capacity × depth of discharge × inverter efficiency ÷ (load + the station’s own draw). The table below uses that approach, with my assumptions of 90% usable capacity, 90% inverter efficiency and about 15W of self-consumption with the inverter on. That works out to about 2,440Wh available for AC loads.
| Load | Assumed average draw | Estimated runtime |
|---|---|---|
| Wi-Fi router | 12W | ~90 hours |
| Starlink Mini (via AC adapter) | 35W | ~49 hours |
| CPAP, no heated humidifier | 40W | ~44 hours (5+ nights) |
| 50-inch LED TV | 100W | ~21 hours |
| Full-size refrigerator (cycling average) | 150W | ~15 hours |
| RV rooftop AC, 13,500 BTU (running) | 1,300W | ~1.9 hours |
| Microwave, 1,000W cooking power (~1,500W draw) | 1,500W | ~1.6 hours of cooking |
A refrigerator’s average depends a lot on the model, the room temperature and how often the door opens. Look up yours with our guide to how many watts a refrigerator uses. Anything with a compressor also has a startup surge. Read surge watts vs running watts before counting on a 13,500 BTU RV air conditioner starting, especially without a soft-start kit.
Power Lifting is for heaters, not motors
The 4,800W “Power Lifting” figure is easy to misread. BLUETTI’s FAQ says Power Lifting handles up to 4,800W “only for pure resistive loads like heaters, hair dryers, electric stoves, and ovens.” It does this by lowering voltage, so a 1,800W kettle simply heats more slowly instead of tripping the inverter. It doesn’t help a well pump or an air conditioner start.
RV hookup: TT-30 and a 12V/30A port
For RV owners, the outlets are the main draw. The TT-30 lets you plug a 30A RV shore cord straight into the station, so the RV’s own outlets and converter run from the battery. On the DC side, BLUETTI uses an XT90 connector for the 12V/30A output. The FAQ says the bigger connector was chosen because 30A of continuous current calls for “higher current capacity.” BLUETTI suggests an XT90-to-Anderson cable to feed an RV’s 12V system for pumps, fans and lights.
Two limits to plan around:
- All DC outputs share a 400W cap and one switch. BLUETTI says you can use every DC port at once, but the total tops out at 400W, and you can’t switch the 12V port and the USB ports separately.
- The TT-30 shares the 2,400W inverter. A 30A RV service can deliver up to 3,600W, so you’ll need to manage big loads like the AC, microwave and electric water heater so they don’t run together.
Charging: fast on AC plus solar, slow from a car socket
| Charging method | Input (BLUETTI) | BLUETTI’s listed time |
|---|---|---|
| AC + solar together | 2,400W | 80% in 78 minutes, full in 1.6 hours |
| AC only | 1,800W | Full in 2 hours |
| Solar only | 1,200W (12–60V, 22A) | Full in 4.1 hours |
| Charger 2 (alternator + solar) | 1,200W | Full in about 3.2 hours |
| Charger 1 (alternator) | 560W | Full in about 6.7 hours |
| 24V car socket | 200W | Full in 15.6 hours |
| 12V car socket | 100W | Full in 30.6 hours |
The 60V solar limit is the spec to watch. BLUETTI’s FAQ recommends 2S2P for its 200W panels and 2P (parallel) for its 350W and SORA 500 panels. That’s because two of the larger panels in series would go past 60V open-circuit. If you’re mixing in third-party panels, check the Voc on the label, and leave headroom for cold mornings, when Voc rises. Our solar panel specs guide shows how to read it.
BLUETTI also says you can charge the Elite 300 from a separate 12V, 24V or 48V lithium battery through the solar input with a clamp-to-XT60 cable. Power is capped at 100W, 200W or 398W respectively, unless you use one of the Charger units.
UPS and home backup
BLUETTI lists a switchover time of 10 ms or less, and says the Elite 300 keeps “Wi-Fi online,” security systems armed and computers running through an outage. Pass-through output from the wall is capped at 1,800W in the U.S. For a home-office desk, a fridge or a network rack, that’s plenty. For a whole-home setup with a transfer switch, a bigger expandable system is a better fit. See our transfer switch vs interlock guide and generator vs battery backup for the bigger picture.
No expansion: the main trade-off
BLUETTI’s FAQ is direct about this: the Elite 300 “does not have a dedicated expansion port and cannot directly link with B80, B230, B300, B300K, or B500K batteries.” The only workaround BLUETTI lists is charging it from one of those batteries through Charger 2. If you think you’ll want 6kWh or more later, the Apex 300 is the BLUETTI model built for expansion.
| If you want… | Look at |
|---|---|
| The most capacity per pound, standalone | Elite 300 |
| Expandable capacity and 240V options | BLUETTI Apex 300 |
| A smaller, cheaper 2kWh unit | BLUETTI Elite 200 V2 |
| Something you can carry one-handed to a campsite | A sub-300Wh unit like the Elite 30 V2 |
Who the Elite 300 is for
- Owners of 30A RVs and trailers who want a TT-30 outlet and a 12V/30A feed in one box.
- Apartment dwellers and renters who want 3kWh of backup without a permanent install.
- Remote workers who need a desk setup and internet to ride through outages with a 10 ms switchover.
- Not the best fit for anyone who plans to add batteries later or needs 240V.
Check current pricing and bundles on BLUETTI’s Elite 300 page. On Oct. 17, bundles included the Elite 300 with a 350W panel for $1,399 and with Charger 2 for $1,599.

FAQ
How much does the BLUETTI Elite 300 weigh?
BLUETTI lists about 26.3 kg (57.98 lb) for the U.S. version. The company notes that weight varies by region because outlet types and internal parts differ.
Can the Elite 300 be expanded with extra batteries?
No. BLUETTI says it has no expansion port and can’t link with B230, B300, B300K or B500K batteries. It can only be charged from them through Charger 2.
Can the Elite 300 run an RV air conditioner?
BLUETTI lists RV air conditioners among the loads it can run, and its 2,400W rating covers the running draw of a typical 13,500 BTU unit. Starting surge is the limiting factor, so a soft-start kit helps. Runtime would be about two hours (estimate).
What’s the maximum solar input?
1,200W at 12–60V and up to 22A. Combined with AC charging, it can take 2,400W total, and BLUETTI lists a full charge in 1.6 hours that way.
Does the Elite 300 work as a UPS?
Yes. BLUETTI lists a switchover time of 10 ms or less, with up to 1,800W of pass-through output from the wall in the U.S.
What’s the warranty?
BLUETTI’s U.S. spec table lists five years.
Bottom line
On paper, the BLUETTI Elite 300 is a strong choice for anyone who wants 3kWh without a 70-plus-pound box. At $1,199 on BLUETTI’s store, it brings a TT-30 outlet, a 12V/30A port, fast 2,400W AC-plus-solar charging and a five-year warranty. Its one real limit is that it can’t take expansion batteries. If you know 3kWh is enough, it’s an easy one to recommend. If you might want more later, start with the Apex 300.
