Main trade-off
PECRON E1500LFP V3
Check for the current 1000W XT60-input version. Older E1500LFP units use a different solar connector and voltage window.
Head-to-head
Choose E1500LFP V3 if your overnight energy use is too high for a 1kWh station or you need its higher-current 12V connection. Choose Mega 1 if a lighter 1024Wh unit covers the trip and you prefer to expand later. PECRON adds 50% more base capacity, but it also adds 10.6 lb.
Before you choose
With an 80% usable-energy allowance, PECRON leaves about 329Wh after the job while Mega 1 falls about 81Wh short.
What this is based on
1536 × 0.8 − 900 = 328.8Wh. 1024 × 0.8 − 900 = −80.8Wh. This is a planning screen, not a guarantee for a particular fridge.
Main trade-off

Main trade-off
The 36-minute full-charge claim requires AC and solar together.


Compare the updated PECRON E1500LFP V3 with OUPES Mega 1 by overnight energy needs, 12V output, solar input and carrying weight.
PECRON’s larger battery is useful for overnight energy, while Mega 1 makes the initial carry easier.
Winner by situation
At an assumed 80% usable energy, PECRON allows about 1229Wh and Mega 1 about 819Wh.
Mega 1 weighs 10.6 lb less.
The V3 30A connection has the current headroom, while a 10A socket does not.
Both have defined matching expansion systems.
What matters in practice
With an 80% usable-energy allowance, PECRON leaves about 329Wh after the job while Mega 1 falls about 81Wh short.
1536 × 0.8 − 900 = 328.8Wh. 1024 × 0.8 − 900 = −80.8Wh. This is a planning screen, not a guarantee for a particular fridge.
PECRON adds 50% nominal energy and 10% continuous AC output while weighing about 38.1% more.
1536 ÷ 1024 = 1.5, 2200 ÷ 2000 = 1.1 and (38.4 − 27.8) ÷ 27.8 × 100 = 38.1%.
At 12V, a 15A load is 180W. That exceeds a 12V 10A, 120W socket but falls below the V3 30A output rating.
12 × 15 = 180W, compared with 12 × 10 = 120W and 12 × 30 = 360W. Suitable cables, fusing and connectors remain essential.

PECRON, E1500LFP V3
A sensible middle step when 1kWh feels tight but a 2kWh station is more weight than you want. The current V3 adds a straightforward XT60 solar connection and a useful 30A DC output.

OUPES, 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.
Meaningful differences
| What changes | PECRON E1500LFP V3 | OUPES Mega 1 | Why it matters |
|---|---|---|---|
| Battery capacity | 1536Wh | 1024Wh | PECRON stores 50% more nominal energy. |
| Continuous AC output | 2200W | 2000W | The inverter gap is much smaller than the capacity gap. |
| Listed weight | 38.4 lb | 27.8 lb | Mega 1 saves 10.6 lb. |
| Maximum solar input | 1000W on V3 | 800W | The V3 solar input is higher than the older E1500LFP specification. |
| Higher-current 12V output | 12V 30A on V3 | 12V 10A car output | The PECRON connection suits larger compatible DC loads with correct wiring. |
| Maximum expansion capacity | 9216Wh with two EP3800 batteries | 5120Wh with two B2 batteries | Both expand, but their batteries and cables are brand-specific. |
What you give up
What matters in practice
Measure the watt-hours needed between charging opportunities before choosing a battery size.
A refrigerator’s compressor wattage does not reveal its total overnight energy use because it cycles. Measure watt-hours over the hours you need to cover, then add a reserve allowance. E1500LFP V3 starts with 512Wh more than Mega 1, which is useful when the measured requirement already pushes the limits of a 1kWh station.
PECRON has updated E1500LFP hardware over time. This comparison covers V3 with 1000W solar input and the higher-current 12V connection. Older material can still show 700W solar and a different connector arrangement. Confirm the current Amazon listing’s specification and the delivered model before buying accessories around the V3 features.
The V3 12V 30A output offers more current headroom than the usual 12V 10A car socket. That can suit a larger compatible DC setup, but the load, cable, fuse, connector and polarity all have to match. A 30A output is not permission to connect high-current equipment through a cable designed for a cigarette-lighter socket.
What the facts say
Useful conclusions from the current portable power stations comparison, followed by the checked facts used to reach them.
Only 5 of 50 models checked match every need here: “I want efficient power for a 12V fridge”, “I may add battery capacity later”, and “I want power for campsites and weekends away”.
5 matching models from 50 checkedPECRON E1500LFP V3 lists 1,536 Wh for battery capacity, 50% above OUPES Mega 1 at 1,024 Wh.
Match countThe count uses the current product-to-need assignments for “I want efficient power for a 12V fridge”, “I may add battery capacity later”, and “I want power for campsites and weekends away”. A need with no documented match does not count.
Calculation noteThis compares nominal watt-hour capacity. Real delivered energy depends on inverter losses, temperature and load. 50 of 50 models have comparable published figures for context.
