Most buyers should choose the BLUETTI Elite 300. It has a NEMA TT-30 RV outlet and a 12V/30 A DC port, takes 1,200 W of solar, switches over in 10 ms or less, and weighs about 58 lb. The BLUETTI Elite 400 is the one to get if capacity comes first: it holds 3,840 Wh against 3,014 Wh, runs 2,600 W, and rolls on two rear wheels.
Our sources are BLUETTI’s US spec pages for both units and BLUETTI’s listing photos, read in November 2026. We haven’t tested either model, so this comparison reflects published specs only.
BLUETTI Elite 300: the better-equipped one
Who it's for: RV owners and home backup buyers who want about 3 kWh with a TT-30 outlet, without adding batteries.
Strengths
- Built-in TT-30 RV outlet and 12V/30 A DC port
- 1,200 W solar input
- Rated for 6,000+ cycles to 80%
Weaknesses
- Can't add expansion batteries
- Heavy to carry at about 58 lb
The Elite 300 has the richer port panel. Besides 4 standard AC outlets, it has a NEMA TT-30, a 12V/30 A DC port, USB-C at 100 W and 140 W, two 15 W USB-A, and a 120 W car outlet. Its 2,400 W output reaches 4,800 W in Power Lifting mode for resistive loads like heaters and hair dryers, and bypass output is 1,800 W.
Charging is faster in mixed setups: 1,800 W from AC fills it in about 2 hours, solar takes up to 1,200 W, and AC plus solar together reach 80% in 78 minutes. Its 3,014.4 Wh of LiFePO4 is rated for 6,000+ cycles to 80% capacity.
The limit is growth: BLUETTI lists no compatible add-on battery, naming the B80, B230, B300, B300K, and B500K as ones it can’t link with.
BLUETTI Elite 400: more energy, more surge
Who it's for: Home backup buyers who want almost 4 kWh in one box they can roll between rooms.
Strengths
- 3,840 Wh in one unit
- Telescoping handle for rolling it
- 5,200 W surge
Weaknesses
- Heavy at 85.98 lb
- Only 4 AC outlets

The Elite 400 adds 826 Wh, for 3,840 Wh in total. It also runs harder: 2,600 W continuous, a 5,200 W surge, and 3,900 W of lifting power for suitable loads. Its 9 outlets are 4 AC, two 100 W USB-C, two 15 W USB-A, and a 120 W car port.
Its inputs are 1,800 W of AC and 1,000 W of solar, plus car, generator, and lead-acid battery charging. BLUETTI’s listing photos show two rear wheels and a telescoping handle, which brings it to 41.02 in tall when raised.
The downsides: it weighs 85.98 lb and its UPS switching time is 15 ms. An expansion battery isn’t listed.
