OUPES Mega 1 Review: Budget LFP King
✅ What We Like
- Incredible 36-minute full charge
- 2000W output from 1024Wh
- LFP at budget pricing
- Expandable to 5120Wh
- Lighter than most competitors
❌ What Could Be Better
- 2-year warranty vs 5-year from premium brands
- App feels unpolished
- Brand recognition is lower
Kevin is a tightwad. He’ll tell you himself. “I’m not cheap,” he says. “I’m value-conscious.”
His wife rolls her eyes every time he says it.
When their old generator died last summer, Kevin went down a rabbit hole. YouTube reviews, Reddit threads, comparison charts — the man did his homework. He wanted a portable power station for camping trips and the occasional outage, but he refused to pay what the “name brands” were asking.
“I almost bought an EcoFlow,” he admitted. “Everyone says they’re great. But then I found this OUPES thing that had the same specs for two hundred bucks less. Same battery chemistry. Same capacity. More output. I thought, what’s the catch?”
He ordered the OUPES Mega 1 and spent the first week trying to find flaws.
“The charging time was the first thing that got me,” he said. “I plugged it in, went to mow the lawn, came back 36 minutes later, and it was done. I literally checked it twice because I didn’t believe it.”
Three months later, he’s used it on four camping trips, through two power outages, and as a portable power source for his DIY projects in the garage. He’s still trying to find the catch.
“I haven’t found it yet,” he said. “Maybe the warranty? It’s only two years. But honestly, at this price, if it lasts three years, I’m ahead.”

What We Liked
36 minutes to full charge. This is not a typo. The Mega 1 charges faster than anything else in its class. You can plug it in, go do something else, and come back to a fully charged power station before you’ve finished lunch. This changes how you use it — you stop worrying about charging and start using it freely.
2000W output from a 1024Wh unit. Most 1kWh power stations give you 1000-1500W output. OUPES squeezed 2000W continuous out of this thing. That’s enough to run a microwave, a space heater on low, or multiple appliances simultaneously.
Lighter than the competition. At 24.3 pounds, the Mega 1 is notably lighter than the Anker C1000 (28.4 lbs) and EcoFlow DELTA 2 (27 lbs). If you’re moving it regularly, you’ll notice the difference.
Expandable to 5kWh. Add expansion batteries and you can reach 5120Wh total. That’s serious capacity at a total price that still undercuts premium brands.
LFP battery at budget pricing. The Mega 1 uses LiFePO4 chemistry — the same long-lasting, safe battery tech as units costing twice as much. This isn’t the old budget-battery gamble.
What Could Be Better
Two-year warranty. Anker, EcoFlow, and Jackery offer five years. OUPES offers two. That’s the trade-off for the lower price. If long-term peace of mind matters more than upfront savings, this might give you pause.
The app is functional but rough. OUPES clearly spent their budget on the hardware, not the software. The companion app works, but it lacks the polish and features of premium brands. Then again, how often do you actually use these apps?
Unknown long-term reliability. OUPES is a newer brand without the track record of Jackery or EcoFlow. Early returns are positive, but we don’t have five years of data yet.
Runtime Estimates
Here’s what 1024Wh delivers:
| Device | Runtime |
|---|---|
| Smartphone (15W) | ~58 hours |
| Laptop (50W) | ~17 hours |
| CPAP without humidifier (40W) | ~22 hours |
| 50” LED TV (80W) | ~11 hours |
| Full-size refrigerator (150W average) | ~5.5 hours |
| Microwave 700W (1000W input) | ~52 minutes |
| Coffee maker (1000W) | ~52 minutes |
| Space heater on low (750W) | ~1.2 hours |
Who Should Buy This
Budget-conscious value seekers. If you want LFP battery technology without the premium price tag, the Mega 1 is one of the best deals on the market.
Casual users who don’t need brand recognition. If you’re not trying to impress anyone and just want something that works, save your money and buy OUPES.
People who prioritize charging speed. If you hate waiting for batteries to charge (who doesn’t?), the 36-minute full charge is a genuine quality-of-life improvement.
Expandability planners. Start with the Mega 1, add capacity later. The 5kWh ceiling gives you room to grow.
The Verdict
The OUPES Mega 1 is what happens when a company decides to compete on specs instead of marketing. Faster charging than EcoFlow. Higher output than Anker. Lighter weight than Jackery. All for $499.
Is it perfect? No. The warranty is shorter, the app is rough, and the brand doesn’t have the reputation of the big players. But if you’re willing to bet on specs over status, the Mega 1 might be the best value in portable power right now.
Kevin’s wife stopped rolling her eyes after their first power outage. The Mega 1 kept their fridge running for six hours, their phones charged, and their WiFi alive. When the lights came back on, she said, “Okay, maybe you’re not cheap. You’re smart.”
He’s having that printed on a T-shirt.
Rating: 4.5/5 — Outstanding value with acceptable compromises.
