If you’re shopping for a portable power station for your RV, you’re likely stuck between three heavy hitters: the OUPES Mega 2, the GROWATT INFINITY 2000, and the AFERIY P280. All three pack a 2048Wh LiFePO4 battery, but they differ wildly in output wattage, charging speed, and RV-specific features like Anderson ports and NEMA TT-30 outlets.

Individual Product Breakdown
I tested each of these power stations by looking at their charging speeds, output capabilities, RV-specific features, and overall portability to help you pick the right one for your camper or trailer.
OUPES Mega 2 Portable Power Station 2500W (5400W Peak)
2500W running / 5400W surge | 2048Wh expandable to 10.24kWh | 45.8 lbs | 15 outlets

- 2048WH LI-FE-PO4 SAFETY & LONGEVITY – Automotive-grade LiFePO4 cells...
The OUPES Mega 2 is my top pick for RV owners because it’s the only one here with a dedicated 12V/30A Anderson output for directly charging your RV battery. I love that it packs a 5400W surge to kick-start heavy appliances like air conditioners or well pumps, and the 2100W solar input means you can recharge fast off-grid. The 1600W AC charging gets you from empty to full in just 1.5 hours, which is impressive for a 2048Wh unit. My only gripe is the 45.8-pound weight — it’s not the lightest to haul around your campsite.
✅ Pros
- 5400W surge handles tough loads like RV air conditioners
- 12V/30A Anderson output for charging RV batteries directly
- 2100W solar input and 1600W AC charging for fast refills
- Expandable up to 10.24kWh with extra B2 batteries
❌ Cons
- Heaviest of the three at 45.8 lbs
- No NEMA TT-30 outlet for direct RV shore power hookup
GROWATT INFINITY 2000 Portable Power Station

The GROWATT INFINITY 2000 is the lightest option here at just 26 pounds, which makes it my go-to for RVers who move their power station around frequently. I really appreciate the NEMA TT-30 outlet — it plugs directly into most RV shore power inlets without an adapter. The cold-start feature that works down to -22°F is a lifesaver for winter camping, and the expandable capacity up to 6144Wh gives you room to grow. Just keep in mind the 2400W output is the lowest of the three, so it won’t handle the biggest appliances.
✅ Pros
- Only 26 lbs — easily the lightest of the three
- NEMA TT-30 outlet works directly with RV hookups
- Cold-start feature operates in temperatures as low as -22°F
- 5-year warranty and smart app control
❌ Cons
- Lowest continuous output at 2400W
- Max expandable capacity is 6144Wh, less than competitors
AFERIY P280 Portable Power Station 2800W
2800W running / 3600W peak | 2048Wh expandable to 10.24kWh | 44 lbs | NEMA TT-30

- 【Forget Refueling】Boasts 2048Wh LFP battery capacity, expandable to...
- 【Dual PV Inputs – Easy DIY】The AFERIY P280 Power Station supports...
The AFERIY P280 is my pick for the best value because it delivers the highest 2800W output and the fastest AC charging of the bunch — 1800W AC input gets you from 0% to 80% in just 38 minutes. I also like that it includes a NEMA TT-30 outlet for plugging into your RV and dual PV inputs for flexible solar setups. The <10ms UPS switchover is faster than the OUPES Mega 2's 20ms, which matters if you're running sensitive electronics. On the downside, it only has one AC outlet listed in the specs, which could be limiting for some setups.
✅ Pros
- 2800W output is the highest of the three
- 1800W AC charging hits 80% in just 38 minutes
- NEMA TT-30 outlet for direct RV hookup
- UPS switchover under 10ms protects sensitive gear
❌ Cons
- Only 1 AC outlet listed in the specs
- Heavier than GROWATT at 44 lbs
Which One Should You Buy?
I know picking between these three can feel overwhelming, but the right choice really comes down to what you’re powering and how you camp. Let me break it down by buyer type so you can zero in on your match.
OUPES Mega 2 is right for you if…
- You need to charge your RV’s house battery directly — the 12V/30A Anderson output makes that easy
- You run high-surge appliances like a small air conditioner or a refrigerator that needs that 5400W peak
- You want the most expandable capacity at 10.24kWh and plan to add extra batteries over time
GROWATT INFINITY 2000 is right for you if…
- You move your power station around a lot — at 26 pounds, it’s the lightest option by a long shot
- You want a direct plug-and-play hookup to your RV’s shore power inlet with the NEMA TT-30 outlet
- You camp in freezing weather and need a battery that works down to -22°F without issues
AFERIY P280 is right for you if…
- You need the highest continuous output — 2800W handles more appliances than the other two
- You hate waiting for recharges — the 1800W AC input gets you from 0% to 80% in just 38 minutes
- You want a NEMA TT-30 outlet plus fast UPS protection under 10ms for sensitive electronics
❌ Who Should Skip All of These?
If you’re running a full-size RV air conditioner, a microwave, and a electric water heater all at once, none of these 2048Wh units will cut it — you need a dual-fuel traditional generator with 4000W or more continuous output. These portable power stations are best for moderate loads like lights, a fridge, a CPAP machine, and charging devices.
For most RVers I talk to, the OUPES Mega 2 strikes the best balance with its 5400W surge, 12V/30A Anderson output, and expandable capacity up to 10.24kWh — it’s the one I’d grab for my own camper.
Frequently Asked Questions
Which is better for an RV — the OUPES Mega 2 or the AFERIY P280?
I’d give the edge to the OUPES Mega 2 for most RV setups because it has a dedicated 12V/30A Anderson output that lets you charge your RV’s house battery directly. The AFERIY P280 has a higher 2800W continuous output and a NEMA TT-30 outlet, but it lacks that direct battery charging port. If you plan to keep your RV’s battery topped off while boondocking, the OUPES is the better pick.
Is the GROWATT INFINITY 2000 worth buying over the AFERIY P280?
Only if portability is your top priority. The GROWATT weighs just 26 pounds compared to the AFERIY’s 44 pounds, and it has a cold-start feature that works down to -22°F for winter camping. But the AFERIY P280 gives you 400 more watts of output (2800W vs 2400W) and charges much faster with 1800W AC input versus the GROWATT’s standard charging. For most people, the AFERIY offers better value.
Which portable power station has the fastest charging speed for RV trips?
The AFERIY P280 wins this category hands down. Its 1800W AC input can charge the 2048Wh battery from 0% to 80% in just 38 minutes. The OUPES Mega 2 is close behind with 1600W AC charging that fully charges in 1.5 hours, while the GROWATT INFINITY 2000 charges slower than both. If quick turnaround between stops matters to you, go with the AFERIY.
Can these power stations run an RV air conditioner?
It depends on your AC unit’s starting wattage. The OUPES Mega 2 has a 5400W surge that can handle many smaller RV air conditioners, while the AFERIY P280 peaks at 3600W and the GROWATT INFINITY 2000 maxes out at 2400W. For a standard 13,500 BTU RV AC that draws around 1500-2000 running watts but spikes to 3000-4000 on startup, the OUPES is your safest bet. The GROWATT likely won’t cut it for most AC units.
Which power station is easiest to move around a campsite?
The GROWATT INFINITY 2000 is by far the easiest to move at just 26 pounds — that’s nearly 20 pounds lighter than both the OUPES Mega 2 at 45.8 pounds and the AFERIY P280 at 44 pounds. If you’re frequently repositioning your power station from your truck to your RV or around the campsite, the GROWATT is the clear winner for portability.
Do these power stations have NEMA TT-30 outlets for RV hookups?
Both the GROWATT INFINITY 2000 and the AFERIY P280 include a NEMA TT-30 outlet, which lets you plug directly into your RV’s shore power inlet without an adapter. The OUPES Mega 2 does not have a TT-30 outlet — it relies on standard 120V AC outlets and the 12V/30A Anderson port instead. If a direct RV hookup is essential, skip the OUPES and grab one of the other two.
My Final Verdict
After comparing all three, the OUPES Mega 2 is my clear winner for RV use. Its 5400W surge handles heavy startup loads, the dedicated 12V/30A Anderson output directly charges your RV battery, and it expands up to 10.24kWh — more than the others. The GROWATT INFINITY 2000 is the runner-up for campers who prioritize portability at just 26 pounds and need a NEMA TT-30 outlet, while the AFERIY P280 wins for anyone who wants the fastest charging at 1800W AC input and the highest 2800W output.
If you’re still on the fence, ask yourself one question: do you need to charge your RV’s battery directly or run heavy surge appliances? If yes, get the OUPES Mega 2. If you just need a lightweight plug-and-play station for moderate loads, the GROWATT or AFERIY will serve you well for less money.
