The 36-minute full-charge claim requires AC and solar together.
Head-to-head
OUPES Mega 1 vs Anker SOLIX C1000 Gen 2: Same base reserve and output, Mega expands while Anker carries lighter
The short answer
Choose Mega 1 if you want to add matching batteries later or use up to 800W of compatible solar input. Choose C1000 Gen 2 for the lighter carry and 140W USB-C charging. Both start with 1024Wh and 2000W continuous AC output, so there is no base-capacity or steady-power reason to choose one over the other.
Before you choose
The reasoning and the trade-offs
The base battery alone does not settle a full working day
At a steady 150W, either estimates about 5.46 hours using an 80% usable-energy allowance.
What this is based on
1024 × 0.8 ÷ 150 = 5.46 hours. This is a planning estimate. An eight-hour job at that load needs 1200Wh delivered before additional reserve.
Main trade-off
Anker SOLIX C1000 Gen 2
Unlike the first-generation C1000, Gen 2 does not accept an expansion battery and has no built-in light.

About this comparison
Compare OUPES Mega 1 and Anker C1000 Gen 2 by expansion, solar input, USB-C and equal 1024Wh capacity with clear appliance-load calculations.
These share the same core battery and inverter numbers, but only Mega 1 offers a matching expansion route.

What matters in practice
The differences that matter
The base battery alone does not settle a full working day
At a steady 150W, either estimates about 5.46 hours using an 80% usable-energy allowance.
How we reached this conclusion
1024 × 0.8 ÷ 150 = 5.46 hours. This is a planning estimate. An eight-hour job at that load needs 1200Wh delivered before additional reserve.
Mega 1 has a defined route to five times its starting reserve
With two compatible B2 batteries, listed system capacity reaches 5120Wh.
How we reached this conclusion
5120 ÷ 1024 = 5. Extra batteries are sold separately and do not raise the 2000W inverter rating.
The extra solar acceptance is a third higher
Mega 1’s 800W limit is 33.3% above the Anker’s 600W limit.
How we reached this conclusion
(800 − 600) ÷ 600 × 100 = 33.3%. This compares maximum accepted power, not expected daily harvest or full-charge times.
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
Anker SOLIX, C1000 Gen 2
C1000 Gen 2
A 24.9-pound 1,024Wh station with a 2,000W inverter, 140W USB-C and a 49-minute app-enabled fast-charge mode.
- Best matched use
- Maximum practical output in a carryable 1kWh box
Checked facts
- 1,024Wh LFP capacity, 2,000W rated AC output and 3,000W peak
- About 24.9 lb with a 140W USB-C port
- 600W solar input, 10ms transfer and a 49-minute advertised full AC recharge in UltraFast mode
Meaningful differences
What changes the fit
| What changes | OUPES Mega 1 | Anker SOLIX C1000 Gen 2 | Why it matters |
|---|---|---|---|
| Battery capacity | 1024Wh | 1024Wh | The base energy budget is equal. |
| Continuous AC output | 2000W | 2000W | Both have the same combined steady load limit. |
| Battery expansion | Up to 5120Wh with two matching B2 batteries | No expansion battery support | Mega 1 can grow to five times its base energy. |
| Maximum solar input | 800W | 600W | Mega 1 offers more solar acceptance when the array can provide it. |
| Listed weight | 27.8 lb | 24.9 lb | Anker saves 2.9 lb before accessories. |
| Fastest USB-C output | 100W | 140W | Anker gives more headroom to a compatible high-power laptop. |
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 Anker SOLIX C1000 Gen 2
- The 49-minute mode must be enabled in the app and increases charging noise and electrical demand.
What matters in practice
How to make the call
Choose based on future reserve and the ports you use, not the identical 2000W output headline.
Think about the second year of ownership
Mega 1 lets the initial 1kWh purchase become a larger system through matching B2 batteries. C1000 Gen 2 stays at its built-in capacity. If longer outages are the likely next problem, this is the meaningful difference. Budget for the expansion batteries and cables rather than treating the maximum system capacity as included in the station price.
A shared inverter rating makes appliance screening simple
Both are rated for 2000W of continuous AC output. Your same list of steady loads should pass or fail that first check on either unit. That does not settle startup demand, individual socket limits or runtime. A kettle and a small appliance can fit together electrically and still drain a 1kWh battery quite quickly.
The Anker advantage is the daily carry and laptop connection
C1000 Gen 2 is 2.9 lb lighter and offers a 140W USB-C port. Those benefits are easy to use on every trip if your laptop supports them. Mega 1’s higher solar ceiling is useful only when a suitable array exceeds 600W, so a traveler with one small folding panel should not give that specification undue weight.
What this comparison cannot tell you
- The same nominal capacity does not establish identical measured AC or USB efficiency.
- Advertised maximum expansion capacity is not included with a standalone station.
