The catch
OUPES Mega 1
You only get the 36-minute full-charge claim when AC and solar are used together.
Side by side
OUPES Mega 1 vs BLUETTI AC180: AC180 starts with more energy, whereas Mega is lighter to carry and expands
Quick verdict
A lighter, expandable setup with higher rated output points to the Mega 1. The AC180 trades extra weight for a little more built-in runtime.
Before you buy
Why, and what it costs you
Using a common load makes reserves easier to compare
Modeled at a steady 300W load, OUPES Mega 1 gets about 2.7 hours and BLUETTI AC180 gets 3.1 hours.
Where this comes from
With inputs of 1024Wh and 1152Wh, hours = nominal Wh × 0.8 / 300W. The 80% factor is a shared planning allowance for unusable energy and conversion losses and not a measured efficiency. Runtime shifts with idle draw, temperature and the real load.
The catch
BLUETTI AC180
It weighs about 35.27 pounds, much more than newer 1kWh models, and has just one USB-C port.
OUPES Mega 1
- Why pick it
- Take the unit along often
- Run a supported load that falls between 1800W and 2000W
- The catch
- You only get the 36-minute full-charge claim when AC and solar are used together.
BLUETTI AC180
- Why pick it
- Have more energy inside the base unit
- Your loads are already under 1800W
- The catch
- It weighs about 35.27 pounds, much more than newer 1kWh models, and has just one USB-C port.

Take the unit along often
AC180 weighs 35.27 lb and Mega 1 weighs 27.8 lb, which saves 7.47 lb on every trip. AC180, though, holds 128Wh more for a longer stay.

Have more energy inside the base unit
The AC180 holds 128Wh more, which equals about 20 modeled minutes at 300W. The Mega 1 has the stronger inverter, but that doesn’t extend runtime by itself.

The battery has to carry a steady 300W load
In the shared planning case, OUPES Mega 1 gets 2.7 hours and BLUETTI AC180 gets 3.1. Before you choose a required overnight reserve, measure actual wattage.

I want solar to refill the battery
OUPES Mega 1 takes a maximum input of 800W and BLUETTI AC180 500W. Check your panel strings against the voltage and current limits too. This total is only part of it.

In practice
Differences you will notice
Using a common load makes reserves easier to compare
Modeled at a steady 300W load, OUPES Mega 1 gets about 2.7 hours and BLUETTI AC180 gets 3.1 hours.
How we worked this out
With inputs of 1024Wh and 1152Wh, hours = nominal Wh × 0.8 / 300W. The 80% factor is a shared planning allowance for unusable energy and conversion losses and not a measured efficiency. Runtime shifts with idle draw, temperature and the real load.
The return on every pound you carry
BLUETTI AC180 stores 32.7 nominal watt-hours per pound, and OUPES Mega 1 stores about 36.8.
How we worked this out
The figures are nominal energy over published weight, 1024 / 27.8 and 1152 / 35.27. They compare stored energy per lifting weight rather than measured efficiency or handle comfort.
A higher load ceiling comes with the lighter choice too
Mega 1 trims 7.47 lb from the AC180 carry and adds 200W of continuous output, at the cost of 128Wh of base capacity.
How we worked this out
35.27 - 27.8 = 7.47 lb, 2000 - 1800 = 200W, and 1152 - 1024 = 128Wh.
Option A
OUPES, Mega 1
Mega 1
A starter battery that’s easy to handle and can grow. The 2000W inverter can cover a short high-draw job. Two optional B2 batteries solve a different problem, keeping smaller loads running longer.
- Best for
- A small backup system that could need far more runtime down the line.
Facts we checked
- 2000W continuous AC output, with 1024Wh capacity.
- About 27.8 lb.
- With two B2 batteries, total capacity rises to 5120Wh.
- 1400W AC input and 800W solar input.
- Four AC outlets and two 100W USB-C ports.
- The manufacturer lists transfer within 20ms.
Option B
BLUETTI, AC180
AC180
This 1,152Wh station has four US AC outlets, a wireless charging pad and a 1,800W inverter. The extra battery reserve means a noticeably heavier carry.
- Best for
- Weekend power that stays put, with four AC plugs
Facts we checked
- 1,800W rated AC output from a 1,152Wh LFP battery, within stated temperature limits
- Four 120V outlets, 100W USB-C and a 15W wireless pad, at about 35.27 lb
- A 1,440W Turbo AC charging mode, plus 500W solar input at 12–60V and up to 10A
Spec by spec
Where they really differ
| Spec | OUPES Mega 1 | BLUETTI AC180 | In practice |
|---|---|---|---|
| Nominal battery energy | 1024 Wh | 1152 Wh | The starting runtime budget comes from stored energy. |
| Continuous AC output | 2000 W | 1800 W | Load screening uses this sustained rating, which is separate from surge and boost modes. |
| Lifting weight | 27.8 lb | 35.27 lb | Flat ground is where wheels help. A trunk, step or shelf still takes a lift. |
| Maximum solar input | 800 W | 500 W | Panel voltage, current and per-port limits have to fit as well. |
| Dedicated battery expansion | Supported with compatible equipment | Fixed base capacity | Integrated battery expansion is not the same as charging from an external source. |
| Published transfer limit | 20 ms | 20 ms | Check the exact device being connected. Even a short transfer specification can’t guarantee that every load runs without interruption. |
Trade-offs
What each pick costs you
With OUPES Mega 1
- A 2000W appliance won’t run for hours on 1024Wh.
With BLUETTI AC180
- In ambient temperatures of 86–104°F, BLUETTI caps continuous output at 1,500W. The 2,700W lifting mode isn’t a general continuous rating.
Decision guide
How to decide
Pick the Mega 1 for a lighter, expandable setup and higher rated output. Pick the AC180 if a little more built-in runtime is worth the extra weight.
A narrow band of appliances can change the answer
The Mega 1 is rated for 2,000W and the AC180 for 1,800W. Only the Mega rating covers a genuine 1,900W continuous load, and that is before you check startup and outlet limits.
Capacity and output are not the same purchase
The AC180 holds 128Wh more, which equals about 20 modeled minutes at 300W. The Mega 1 has the stronger inverter, but that doesn’t extend runtime by itself.
A growing kit benefits from solar and expansion
The Mega 1 lists 800W of solar intake along with compatible expansion. The AC180 lists 500W of solar, and its external-battery support is a recharge arrangement. That differs from integrated expansion.
What this page can’t tell you
- Published capacity underlies these runtime figures. They are planning estimates. No hands-on discharge tests were run.
- Home wiring should only be connected to a station through approved transfer equipment, installed by a qualified person. A battery station is not guaranteed to provide medical continuity.

How we countedThe count uses each product's current fit ratings for “I need power at campsites and on weekends away”, “I want backup power for the essentials at home”, and “Solar will be a real part of how I recharge”. A need with no documented match is not counted.
How we calculatedThese are nominal watt-hour ratings. How much energy you get out depends on inverter losses, temperature and load. For context, 50 of 50 models publish comparable figures.
