BLUETTI now sells two 1kWh-class LiFePO4 power stations that sit close together on price: the long-running AC180 with 1,152Wh and 1,800W, and the newer Elite 100 V2 with 1,024Wh and the same 1,800W rating, according to BLUETTI’s spec sheets and the Elite 100 V2 user manual. On paper the AC180 holds about 128Wh more. The Elite 100 V2 answers with a much faster solar input, a 140W USB-C port, a quicker UPS switchover and about 10 pounds less weight. Here’s how the two compare, spec by spec, and which one suits which kind of owner.

Figures come from BLUETTI’s AC180 product page and user manual, the Elite 100 V2 user manual (section 10, Specifications), and the Amazon listings for the BLUETTI AC180 and BLUETTI Elite 100 V2. I haven’t bench-tested either unit yet, so every runtime below is a labeled estimate.
The short answer
- Pick the Elite 100 V2 if you’ll charge from solar, carry the unit often, or want to run a laptop at full speed over USB-C. Its 1,000W solar input is double the AC180’s 500W, and it weighs about 25.3 lb against 35.3 lb.
- Pick the AC180 if you mostly charge from the wall, want four AC outlets plus a wireless charging pad, and like having slightly more stored energy for the money.

Capacity: a 12% edge for the AC180
The AC180 stores 1,152Wh, which is 128Wh, or about 12.5%, more than the Elite 100 V2’s 1,024Wh. In practice that gap is roughly one extra hour on a 100W load. BLUETTI’s own runtime formula in the Elite 100 V2 manual is a useful way to see it: capacity × 90% depth of discharge × inverter efficiency (over 90%) ÷ (load + about 10W of self-consumption).
Worked runtime estimates
| Load (typical draw) | AC180 estimate* | Elite 100 V2 estimate* |
|---|---|---|
| Starlink Mini, about 30W average | ≈ 23 hr | ≈ 21 hr |
| CPAP without humidifier, 40W | ≈ 19 hr | ≈ 17 hr |
| Full-size fridge, about 60W average | ≈ 13 hr | ≈ 12 hr |
| Laptop + monitor, 120W | ≈ 7 hr | ≈ 6.4 hr |
| Microwave, 1,000W | ≈ 55 min | ≈ 50 min |
*Estimates using BLUETTI’s formula: Wh × 0.9 × 0.9 ÷ (load + 10W). Example for the Elite 100 V2 and a 60W fridge: 1,024 × 0.81 ÷ 70 ≈ 11.8 hours. Fridge duty cycles vary a lot with room temperature, so treat these as starting points.
If you aren’t sure what your appliances actually draw, my guide on how many watts a refrigerator uses walks through reading the label and measuring the real number.
Output: same inverter rating, different port mix
Both stations are rated at 1,800W of continuous AC and both offer BLUETTI’s Power Lifting mode, which lets resistive appliances such as kettles, hair dryers and space heaters rated up to 2,700W run at reduced power instead of tripping the inverter. The Elite 100 V2 manual is clear that the real output is still 1,800W in this mode, so a 2,200W kettle simply boils more slowly. Motors and compressors are a different story; the manual notes they can start at two to four times their rated power. My explainer on surge watts vs running watts covers why that matters.
Where the two really differ is on the low-voltage side:
- Elite 100 V2: two USB-C ports, one at 100W and one at 140W (up to 28V/5A), which can run a 16-inch MacBook Pro at full charging speed. It also has two DC5521 barrel ports alongside the car outlet, sharing a 10A total.
- AC180: four AC outlets, four USB-A ports, one 100W USB-C, a 12V/10A car outlet and a 15W wireless charging pad on top. If you have a lot of AC plugs, that extra outlet count saves a power strip.
Charging speed: wall vs sun
From the wall
The AC180 has the edge here. Its Turbo mode pulls up to 1,440W and reaches 80% in about 45 minutes, with a full charge in roughly 1.3 to 1.8 hours, per BLUETTI. Standard mode is about 1,000W. The Elite 100 V2 tops out at 1,200W and also lists 80% in 45 minutes at room temperature, with Standard, Turbo and Silent charging modes you pick on the display or in the app.
From solar
This is the Elite 100 V2’s biggest advantage. It accepts up to 1,000W at 12–60V and 20A, while the AC180 is capped at 500W and 10A on the same voltage window. With a big enough array, the Elite 100 V2 can refill from the sun in roughly half the time.
| Solar array | AC180 estimate* | Elite 100 V2 estimate* |
|---|---|---|
| 200W (real-world ~140W) | ≈ 8.2 hr | ≈ 7.3 hr |
| 400W (real-world ~280W) | ≈ 4.1 hr | ≈ 3.7 hr |
| 800W (real-world ~560W) | Capped at 500W: ≈ 2.8–3.3 hr (BLUETTI figure) | ≈ 1.8 hr |
*Estimates assume panels deliver about 70% of their rating in good sun. Hours = capacity ÷ real-world watts. Mind the voltage limit: two 100W panels in series stay well under 60V open-circuit, but three or four in series can exceed it, so check each panel’s Voc. My guide to MPPT vs PWM charge controllers explains how the built-in controller handles this.
UPS and home backup
Both units support pass-through charging and work as an uninterruptible power supply. The Elite 100 V2 switches in 10 ms or less; the AC180 in 20 ms or less. Ten milliseconds is fast enough for most desktop PCs, routers and network gear. The Elite 100 V2 also has app-based time-of-use and solar-priority modes, so it can charge off-peak and run devices during peak hours.
Size and weight
At about 25.3 lb and 12.6 × 8.5 × 9.8 inches, the Elite 100 V2 is the easier carry by a wide margin. The AC180 is about 35.3 lb and 13.4 × 9.7 × 12.5 inches. If the station lives in a closet for outages, that hardly matters. If it rides to campsites every weekend, 10 pounds is noticeable.
Who should buy which
| You are… | Better fit | Why |
|---|---|---|
| A solar camper or van owner | Elite 100 V2 | 1,000W solar input and lighter body |
| A remote worker with a big laptop | Elite 100 V2 | 140W USB-C and 10 ms UPS |
| Prepping for home outages on wall power | AC180 | More Wh and 1,440W Turbo recharge |
| Running many AC devices at once | AC180 | Four AC outlets plus wireless pad |

FAQ
Is the Elite 100 V2 the replacement for the AC180?
BLUETTI sells both side by side. The Elite 100 V2 is the newer design with more solar input and less weight, while the AC180 remains in the lineup with more capacity.
Can either one be expanded with an extra battery?
Neither lists a plug-in expansion battery. BLUETTI says the AC180 can be recharged from its B80, B230 or B300 batteries in power bank mode, which tops it up rather than adding capacity directly.
Can I use third-party solar panels?
Yes. Both accept panels with MC4 connectors and an open-circuit voltage of 12–60V. BLUETTI advises against mixing different panel types.
Which one is quieter while charging?
The Elite 100 V2 manual lists 50 dB max and includes a Silent charging mode. The AC180 also has a Silent mode at reduced charging power.
Will either run a space heater?
A 1,500W heater fits under both 1,800W ratings. Expect roughly 35 to 40 minutes from either unit (estimate), so they’re better suited to short bursts than all-night heat.
Bottom line
The AC180 gives you a little more stored energy, more AC outlets and faster wall charging. The Elite 100 V2 trades about 128Wh for double the solar input, a 140W USB-C port, a faster UPS and a 10-pound weight saving. For most people who’ll take their station outdoors or pair it with panels, the Elite 100 V2 is the more versatile pick; for wall-charged home backup, the AC180 still makes a strong case.
