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 Anker SOLIX C1000 Gen 2: Anker carries lighter and Mega expands, with the same base reserve and output
Quick verdict
The Mega 1 suits you if you plan to add matching batteries later or use up to 800W of compatible solar input. The C1000 Gen 2 offers the lighter carry and 140W USB-C charging. Each starts with 1024Wh and 2000W continuous AC output, so neither has an edge on base capacity or steady power.
Before you buy
Why, and what it costs you
A full working day isn’t settled by the base battery alone
Using an 80% usable-energy allowance at a steady 150W, either estimates about 5.46 hours.
Where this comes from
1024 × 0.8 ÷ 150 = 5.46 hours. It is a planning estimate. At that load, an eight-hour job needs 1200Wh delivered before any additional reserve.
The catch
Anker SOLIX C1000 Gen 2
Gen 2 has no built-in light and, unlike the first-generation C1000, cannot take an expansion battery.
OUPES Mega 1
- Why pick it
- Your backup plan could eventually reach multiple kilowatt-hours.
- More solar input than the Anker’s 600W ceiling is on your wish list.
- The catch
- You only get the 36-minute full-charge claim when AC and solar are used together.
Anker SOLIX C1000 Gen 2
- Why pick it
- Saving nearly 3 lb matters because you carry the station often.
- Your laptop can take advantage of 140W USB-C charging.
- The catch
- Gen 2 has no built-in light and, unlike the first-generation C1000, cannot take an expansion battery.

What this page compares
OUPES Mega 1 and Anker C1000 Gen 2 compared on expansion, solar input and USB-C, with equal 1024Wh capacity and clear appliance-load calculations.
Core battery and inverter numbers are the same across these, yet a matching expansion route exists only for Mega 1.

In practice
Differences you will notice
A full working day isn’t settled by the base battery alone
Using an 80% usable-energy allowance at a steady 150W, either estimates about 5.46 hours.
How we worked this out
1024 × 0.8 ÷ 150 = 5.46 hours. It is a planning estimate. At that load, an eight-hour job needs 1200Wh delivered before any additional reserve.
A defined route lets Mega 1 reach five times its starting reserve
Add two compatible B2 batteries and the listed system capacity reaches 5120Wh.
How we worked this out
5120 ÷ 1024 = 5. The extra batteries are sold separately, and the 2000W inverter rating stays where it is.
Solar acceptance is higher by a third
Against the Anker’s 600W limit, Mega 1’s 800W limit is 33.3% higher.
How we worked this out
(800 − 600) ÷ 600 × 100 = 33.3%. The comparison is of maximum accepted power and not of expected daily harvest or full-charge times.
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
Anker SOLIX, C1000 Gen 2
C1000 Gen 2
This 24.9-pound, 1,024Wh station has a 2,000W inverter, 140W USB-C and a 49-minute fast-charge mode that you switch on in the app.
- Best for
- As much usable output as a carryable 1kWh box allows
Facts we checked
- 2,000W rated AC output and 3,000W peak, with 1,024Wh LFP capacity
- A 140W USB-C port, at about 24.9 lb
- In UltraFast mode, a 49-minute advertised full AC recharge, plus 10ms transfer and 600W solar input
Spec by spec
Where they really differ
| Spec | OUPES Mega 1 | Anker SOLIX C1000 Gen 2 | In practice |
|---|---|---|---|
| Battery capacity | 1024Wh | 1024Wh | The base energy budget starts equal. |
| Continuous AC output | 2000W | 2000W | Combined steady load limit is the same for both. |
| Battery expansion | Up to 5120Wh with two matching B2 batteries | No expansion battery support | Expansion takes Mega 1 to five times its base energy. |
| Maximum solar input | 800W | 600W | If the array can provide it, Mega 1 accepts more solar. |
| Listed weight | 27.8 lb | 24.9 lb | Before accessories, Anker is 2.9 lb lighter. |
| Fastest USB-C output | 100W | 140W | A compatible high-power laptop gets more headroom from Anker. |
Trade-offs
What each pick costs you
With OUPES Mega 1
- A 2000W appliance won’t run for hours on 1024Wh.
With Anker SOLIX C1000 Gen 2
- To use the 49-minute mode you have to turn it on in the app, and it makes charging louder and draws more power.
Decision guide
How to decide
Base the decision on future reserve and the ports you use, since the 2000W output headline is identical.
Look ahead to your second year of ownership
With matching B2 batteries, a Mega 1 bought as a 1kWh unit can grow into a larger system. The C1000 Gen 2 stays at its built-in capacity. If longer outages are the likely next problem, that is the difference that counts. Set aside budget for the expansion batteries and cables, because the maximum system capacity isn’t included in the station price.
Matching inverter ratings keep appliance screening simple
Each is rated for 2000W of continuous AC output, so your list of steady loads will pass or fail that first check the same way on either unit. It still leaves startup demand, individual socket limits and runtime unsettled. A kettle and a small appliance can fit together electrically and yet drain a 1kWh battery quite quickly.
Anker wins on daily carry and the laptop connection
The C1000 Gen 2 weighs 2.9 lb less and has a 140W USB-C port. If your laptop supports it, you’ll benefit on every trip. The Mega 1’s higher solar ceiling only helps when a suitable array exceeds 600W, so a traveler with one small folding panel shouldn’t weigh that specification too heavily.
What this page can’t tell you
- Identical nominal capacity doesn’t mean measured AC or USB efficiency is identical.
- A standalone station doesn’t come with the advertised maximum expansion capacity.
