Head-to-head
OUPES Mega 1 vs BLUETTI AC180: Mega carries lighter and expands, AC180 starts with more energy
The short answer
Choose Mega 1 for a lighter expandable setup and higher rated output. AC180 gives a little more built-in runtime at the cost of extra weight.
Before you choose
The reasoning and the trade-offs
A common load makes the reserve easier to compare
For a steady 300W load, OUPES Mega 1 models to about 2.7 hours and BLUETTI AC180 to 3.1 hours.
What this is based on
Hours = nominal Wh × 0.8 / 300W. Inputs 1024Wh and 1152Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
Main trade-off
BLUETTI AC180
At about 35.27 pounds, it is substantially heavier than newer 1kWh models. It has only one USB-C port.

Winner by situation
Start with what you need it to do
Carry the unit regularly
Mega 1 weighs 27.8 lb against 35.27 lb for AC180. That saves 7.47 lb on every trip, while AC180 holds 128Wh more for a longer stay.
- OUPES Mega 1
- Better fit
- BLUETTI AC180
- Depends
Keep more energy in the base unit
AC180 has 128Wh more, equivalent to about 20 modeled minutes at 300W. Mega 1 has the stronger inverter, which does not itself extend runtime.

The battery needs to cover a steady 300W load
The shared planning case gives 2.7 hours from OUPES Mega 1 and 3.1 from BLUETTI AC180. Measure actual wattage before choosing a required overnight reserve.

What matters in practice
The differences that matter
A common load makes the reserve easier to compare
For a steady 300W load, OUPES Mega 1 models to about 2.7 hours and BLUETTI AC180 to 3.1 hours.
How we reached this conclusion
Hours = nominal Wh × 0.8 / 300W. Inputs 1024Wh and 1152Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
What you gain for each pound carried
OUPES Mega 1 stores about 36.8 nominal watt-hours per pound, compared with 32.7 for BLUETTI AC180.
How we reached this conclusion
Nominal energy divided by published weight: 1024 / 27.8 and 1152 / 35.27. This compares stored energy per lifting weight, not measured efficiency or handle comfort.
The lighter choice also clears a higher load ceiling
Mega 1 removes 7.47 lb from the AC180 carry and adds 200W of continuous output, while giving up 128Wh of base capacity.
How we reached this conclusion
35.27 - 27.8 = 7.47 lb. 2000 - 1800 = 200W. 1152 - 1024 = 128Wh.
Choice A
OUPES, Mega 1
Mega 1
A manageable starter battery with room to grow. Its 2000W inverter can cover a short high-draw job, while two optional B2 batteries address the very different problem of making smaller loads run longer.
- Best matched use
- A small backup system that may need much more runtime later.
Checked facts
- 1024Wh capacity and 2000W continuous AC output.
- About 27.8 lb.
- Two B2 batteries increase total capacity to 5120Wh.
- 800W solar input and 1400W AC input.
- Two 100W USB-C ports and four AC outlets.
- Manufacturer lists transfer within 20ms.
Choice B
BLUETTI, AC180
AC180
A 1,152Wh station with four US AC outlets, a wireless charging pad and a 1,800W inverter. Its extra battery reserve comes with a notably heavier carry.
- Best matched use
- Stationary weekend power with four AC plugs
Checked facts
- 1,152Wh LFP battery and 1,800W rated AC output under stated temperature limits
- About 35.27 lb with four 120V outlets, 100W USB-C and a 15W wireless pad
- 500W solar input, 12–60V at up to 10A, and a 1,440W Turbo AC charging mode
Meaningful differences
What changes the fit
| What changes | OUPES Mega 1 | BLUETTI AC180 | Why it matters |
|---|---|---|---|
| Nominal battery energy | 1024 Wh | 1152 Wh | Stored energy determines the starting runtime budget. |
| Continuous AC output | 2000 W | 1800 W | This is the sustained rating used for load screening, separate from surge and boost modes. |
| Lifting weight | 27.8 lb | 35.27 lb | Wheels help on flat ground. A trunk, step or shelf still requires a lift. |
| Maximum solar input | 800 W | 500 W | The panel voltage, current and per-port limits must also fit. |
| Dedicated battery expansion | Supported with compatible equipment | Fixed base capacity | Charging from an external source is different from integrated battery expansion. |
| Published transfer limit | 20 ms | 20 ms | Verify the exact connected device. A short transfer specification does not guarantee uninterrupted operation for every load. |
What you give up
Every choice has a cost
If you choose OUPES Mega 1
- 1024Wh will not keep a 2000W appliance running for hours.
If you choose BLUETTI AC180
- BLUETTI limits continuous output to 1,500W in 86–104°F ambient temperatures. The 2,700W lifting mode is not a general continuous rating.
What matters in practice
How to make the call
A narrow appliance band changes the answer
Mega 1 is rated for 2,000W and AC180 for 1,800W. A genuine 1,900W continuous load falls within only the Mega rating, before checking startup and outlet limits.
Capacity and output are different purchases
AC180 has 128Wh more, equivalent to about 20 modeled minutes at 300W. Mega 1 has the stronger inverter, which does not itself extend runtime.
Solar and expansion suit a growing kit
Mega 1 lists 800W solar intake and compatible expansion. AC180 lists 500W solar, with external-battery support working as a recharge arrangement rather than the same integrated expansion.
What this comparison cannot tell you
- Runtime figures are planning estimates from published capacity, not hands-on discharge tests.
- Do not connect a station to home wiring without approved transfer equipment and qualified installation. A battery station is not a medical continuity guarantee.
