The catch
PECRON E1500LFP V3
Make sure you get the current 1000W XT60-input version, since older E1500LFP units have a different solar connector and voltage window.
Side by side
PECRON E1500LFP V3 vs OUPES Mega 1: PECRON brings 50% more base energy and 10.6 lb more to carry
Quick verdict
If your overnight energy use is too much for a 1kWh station, or you need its higher-current 12V connection, the E1500LFP V3 is the answer. If a lighter 1024Wh unit covers the trip and you’d rather expand later, pick the Mega 1. The PECRON brings 50% more base capacity, and 10.6 lb more weight with it.
Before you buy
Why, and what it costs you
These base batteries part ways on a 900Wh overnight plan
Under an 80% usable-energy allowance, about 329Wh is left on PECRON after the job, whereas Mega 1 comes up about 81Wh short.
Where this comes from
1536 × 0.8 − 900 = 328.8Wh. 1024 × 0.8 − 900 = −80.8Wh. It works as a planning screen and gives no guarantee for a particular fridge.
The catch
OUPES Mega 1
You only get the 36-minute full-charge claim when AC and solar are used together.
PECRON E1500LFP V3
- Why pick it
- A 1024Wh battery can’t provide the reserve your measured overnight demand requires.
- The updated V3 12V 30A DC output is a requirement, with suitable wiring.
- The catch
- Make sure you get the current 1000W XT60-input version, since older E1500LFP units have a different solar connector and voltage window.
OUPES Mega 1
- Why pick it
- Your trip fits within the smaller energy budget, and you want a lighter station.
- You need backup that can expand, yet you don’t want to carry the larger base battery each time.
- The catch
- You only get the 36-minute full-charge claim when AC and solar are used together.

What this page compares
The updated PECRON E1500LFP V3 set against OUPES Mega 1 on overnight energy needs, 12V output, solar input and carrying weight.
Mega 1 makes the initial carry easier, and PECRON’s larger battery helps with overnight energy.

In practice
Differences you will notice
These base batteries part ways on a 900Wh overnight plan
Under an 80% usable-energy allowance, about 329Wh is left on PECRON after the job, whereas Mega 1 comes up about 81Wh short.
How we worked this out
1536 × 0.8 − 900 = 328.8Wh. 1024 × 0.8 − 900 = −80.8Wh. It works as a planning screen and gives no guarantee for a particular fridge.
The added weight mostly pays for reserve and not for a much bigger inverter
PECRON weighs about 38.1% more and adds 50% nominal energy and 10% continuous AC output.
How we worked this out
Weight: (38.4 − 27.8) ÷ 27.8 × 100 = 38.1%. Also 1536 ÷ 1024 = 1.5 and 2200 ÷ 2000 = 1.1.
A higher-current connection is needed for a 15A DC load
A 15A load at 12V comes to 180W. That is over a 12V 10A, 120W socket yet under the V3 30A output rating.
How we worked this out
12 × 15 = 180W, against 12 × 10 = 120W and 12 × 30 = 360W. Suitable cables, fusing and connectors are still essential.
Option A
PECRON, E1500LFP V3
E1500LFP V3
A sensible in-between choice if 1kWh feels tight but a 2kWh station would weigh more than you’d like. The current V3 brings a simple XT60 solar connection and a useful 30A DC output.
- Best for
- Extended camping trips and home essentials you’ve measured, with room to add batteries later.
Facts we checked
- 2200W rated 120V AC output from a 1536Wh battery.
- The current V3 comes in at about 38.4 lb.
- XT60 solar input of 1000W, from 11V to 60V and 20A maximum.
- 100W USB-C and 1400W AC charging.
- Expansion to 9216Wh using two EP3800 batteries, plus a 12V 30A DC output.
Option B
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.
Spec by spec
Where they really differ
| Spec | PECRON E1500LFP V3 | OUPES Mega 1 | In practice |
|---|---|---|---|
| Battery capacity | 1536Wh | 1024Wh | Nominal energy is 50% higher on PECRON. |
| Continuous AC output | 2200W | 2000W | The capacity gap is much larger than the inverter gap. |
| Listed weight | 38.4 lb | 27.8 lb | Mega 1 is 10.6 lb lighter. |
| Maximum solar input | 1000W on V3 | 800W | Compared with the older E1500LFP specification, the V3 solar input is higher. |
| Higher-current 12V output | 12V 30A on V3 | 12V 10A car output | With correct wiring, the PECRON connection suits larger compatible DC loads. |
| Maximum expansion capacity | 9216Wh with two EP3800 batteries | 5120Wh with two B2 batteries | Both expand, but each brand has its own batteries and cables. |
Trade-offs
What each pick costs you
With PECRON E1500LFP V3

With OUPES Mega 1
- A 2000W appliance won’t run for hours on 1024Wh.
Decision guide
How to decide
Before picking a battery size, measure the watt-hours you need between chances to recharge.
Begin by measuring overnight energy use
Because a refrigerator cycles, its compressor wattage doesn’t tell you its total overnight energy use. Measure watt-hours across the hours you need to cover, then add a reserve allowance. The E1500LFP V3 starts with 512Wh more than the Mega 1, which helps when your measured requirement already stretches the limits of a 1kWh station.
Treat the V3 suffix as part of your buying check
Over time, PECRON has revised the E1500LFP hardware. This comparison is about the V3, with 1000W solar input and the higher-current 12V connection. Older material may still show 700W solar and a different connector arrangement. Before buying accessories built around the V3 features, confirm the specification on the current Amazon listing and the model that is delivered.
A DC hookup takes more than matching voltage
Compared with the usual 12V 10A car socket, the V3 12V 30A output has more current headroom. That can suit a larger compatible DC setup, but the load, cable, fuse, connector and polarity must all match. Having a 30A output doesn’t mean you can run high-current equipment through a cable designed for a cigarette-lighter socket.
What this page can’t tell you
- The 80% usable-energy allowance is a stated planning assumption and not a measured V3 efficiency result.
- Treat the DC calculation as a compatibility screen and not as installation instructions.

How we countedThe count uses each product's current fit ratings for “I need an efficient way to power a 12V fridge”, “I might expand battery capacity later”, and “I need power at campsites and on weekends away”. 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.
