Independent sources, scored for each model. Mega 2 Pro on 5 of five, E2400LFP on 4.
The OUPES Mega 2 Pro reading covers its product line.
What they say
OUPES Mega 2 Pro
- Owner posts on the Mega line in r/OUPES_info from mid-2026 report a Mega 1 that would not recharge after a full discharge (E022 low cell voltage), trouble charging a B2 from a Mega 3 and an app owners call weak, against praise for OUPES support replacing a bricked unit.
Pecron E2400LFP
- E2400LFP owner posts run from September 2025 into 2026 across r/batteries and r/SolarDIY.
- One owner found the unit drained from above 50 percent to zero overnight, twice in its first two months, with only the DC side switched on (r/batteries, November 2025).
- Another exchanged it for an F3000LFP, citing state-of-charge readings he blamed on the battery management and a 5521 input that cuts out below about 12.2 V (r/SolarDIY, September 2025).
- A third owner says his E2400 does not drain on standby with solar connected and runs its DC output full time (r/SolarDIY, 2026).
The OUPES Mega 2 Pro reading covers its product line.
What they say
OUPES Mega 2 Pro
- The Mega 2 Pro has had no written test of its own, so this reads the Mega 2's.
- TheSolarLab, which earns commission through affiliate links and offers a discount code, measured 83 percent on a 2,330 W load and a 2 hour 7 minute AC charge, saw it shut off instantly at 3,000 W and found 2,100 W of solar hard to reach.
- The Gadgeteer, which earns commission through links, praised its capacity, charging speed and UPS (March 2024).
Pecron E2400LFP
- TheSolarLab, which received its unit from Pecron and earns commission through links and a discount code, ran a 2,275 W load for 36 minutes before the unit overheated and shut off at about 15 percent, then 40.5 minutes, 75 percent of rated, after following Pecron's recalibration advice; it measured a full wall charge in about 81 minutes and a 13.6 W idle draw, and faulted the proprietary solar plug, the missing light and Pecron's phone support (2025).
- Nikktech, testing a European two-outlet unit, recharged it from the wall in about 80 minutes, found it quieter than the other stations in its lab and gave it its Golden Award (October 2025).

What they say
OUPES Mega 2 Pro
- Herb-O-Matic, which earns commission through affiliate links and offers an OUPES discount code, tested a pre-release unit, started a window air conditioner with a 25 A inrush, and found the 0 to 80 percent AC charge met OUPES's one-hour claim (May 2026, about 35,000 views).
- The Old Jarhead, which offers an OUPES discount code, found the unit misread its temperature at 33 to 34 F, hit app firmware-update bugs, and shut down at its 10 percent limit while a B2 still held 27 percent; OUPES committed to a firmware fix before mass production (May 2026, about 6,500 views).
Pecron E2400LFP
- Jasonoid, which marks the video as a paid promotion and offers a discount code, drew 1,700 Wh on AC, 83 percent of rated, and 1,854 Wh through the DC outputs, measured a UPS switchover under 10 ms, ran up to 2,600 W before the inverter shut off, and faulted inverter noise and the 800 W solar ceiling (January 2025, about 35,600 views).
- ReeWray Outdoors, which earns commission through links and offers a discount code, ran AC and DC capacity, solar, load, noise and UPS tests and called it an all-around performer at a budget price (January 2025, about 29,400 views).
Amazon
tiedThe OUPES Mega 2 Pro reading covers its product line; the Pecron E2400LFP reading covers its product line.
What they say
OUPES Mega 2 Pro
- One Amazon review file covers OUPES's Mega 1, Mega 2 and Mega 2 Pro listings (B0DG8JQNS4, B0CNP614R2): 4.5 from 1,502 ratings, 80 percent five-star and 7 percent one-star, and Amazon's review summary describes the Mega 1's 1,400 W charging.
- Its review tags are led by reliability (219 mentions) and charging speed (196), with durability mixed (48).
- The Mega 2 Pro's own listing (B0GXZKZ5ZM) holds 4 ratings and shows as unavailable.
Pecron E2400LFP
- No E2400LFP listing on Amazon US carries a rating, so this reads the E1500LFP, which shares its charge controllers, DC outputs and 48 V expansion batteries.
- Its listing (B0CKWTHM8K), sold by PECRON Energy, reads 4.3 from 117 ratings, 73 percent five-star and 11 percent one-star.
- Amazon's review tags are positive on power (20 of 22 mentions) and value (17 of 22) and split on noise (3 of 5 positive).

OUPES Mega 2 Pro
- No US retailer lists the Mega 2 Pro.

- Owners praise the fast wall charge and overnight refrigerator runtime, against units that died after a full discharge and app dropouts.
