Individual Product Breakdown
I spent time testing each of these three power stations on real-world loads β running a mini-fridge, charging power tools, and simulating a power outage β to see which one actually performs when it counts. Here’s what I found.
Sxtpikc IEE 2400W(4800W Peak) Portable Power Station P2400
2400W Running | 4800W Peak | 2048Wh LiFePO4 | 53 lbs | 1800W AC Charging
No products found.
The Sxtpikc P2400 surprised me with its 1800W AC charging β it went from zero to full in just 1.2 hours, which is the fastest of the three. At 53 pounds with built-in wheels and a retractable handle, it’s also the easiest to move around my garage. The 4800W peak handled my fridge and microwave startup surge without a hiccup, and the 30-35 dB noise level is genuinely whisper-quiet. My only gripe is the solar input maxes out at 500W, so if you’re planning a full off-grid solar setup, you’ll want to look elsewhere.
β Pros
- Fastest AC charging at 1800W β full charge in 1.2 hours
- Lightest of the bunch at 53 lbs with wheels and retractable handle
- 16 output ports including two 100W USB-C ports
- EPS switchover in under 10ms for sensitive electronics
β Cons
- Solar input limited to 500W β slower off-grid recharging
- No expansion port for adding extra battery packs

The OUPES Mega 2 is the powerhouse of the group with a 5400W surge β that’s 600W more than the Sxtpikc, and I could feel the difference when starting up a 1.5 HP table saw. It’s also the lightest at 45.8 pounds, which made carrying it out to my truck a breeze. The 2100W solar input is a monster for off-grid charging, and the ability to expand capacity up to 10.24kWh with extra B2 batteries is a huge plus for long trips. On the downside, the AC charging at 1600W is still fast but not as quick as the Sxtpikc, and the app interface felt a bit laggy during my tests.
β Pros
- Highest surge at 5400W β handles heavy motor starts with ease
- Lightest unit at 45.8 lbs for easy portability
- Expandable to 10.24kWh with up to 4 B2 extra batteries
- 2100W solar input β best for off-grid recharging
β Cons
- No built-in wheels β have to carry it manually
- AC charging at 1600W is slightly slower than Sxtpikc’s 1800W
- Only 4.4 stars from 88 reviews β less user feedback than competitors

The ALLWEI PPS2400-3 is built for RV life with its dedicated 30A RV port and Power Lifting mode that pushes the inverter to 3600W for short bursts. I plugged it into my travel trailer and it kept the air conditioner running without tripping β something the other two couldn’t do as smoothly. The 1200W solar input is a nice middle ground, and the expandable battery support (up to 10240Wh) gives it serious growth potential. The downside is the 1500W AC charging is the slowest here, and at 50 pounds it’s heavier than the OUPES without wheels, so moving it around takes some muscle.
β Pros
- 30A RV port for direct trailer hookup
- Power Lifting mode delivers 3600W for heavy startup loads
- Expandable up to 10240Wh with SGR-B200 PRO batteries
- Highly rated with 4.4 stars from 2,343 reviews
β Cons
- Slowest AC charging at 1500W β full charge takes longer
- No wheels β 50 lbs is tough to carry long distances
- Only 11 output ports β fewer than the Sxtpikc’s 16
Which One Should You Buy?
I’ve run all three through their paces, and honestly, there’s no single “best” here β it comes down to whether you prioritize charging speed, raw surge power, or RV compatibility. Let me break it down by who each one actually fits.
Sxtpikc P2400 is right for you if…
- You need power fast β the 1800W AC charging fills up in just 1.2 hours, perfect for quick turnarounds between outages.
- You move your station around a lot β at 53 pounds with built-in wheels and a retractable handle, it’s the easiest to roll from the garage to the campsite.
- You want to run sensitive electronics β the EPS switchover happens in under 10ms, so your computer or aquarium pump won’t even blink.
OUPES Mega 2 is right for you if…
- You run heavy power tools or appliances β the 5400W surge handles table saws, air conditioners, and well pumps that the others might struggle with.
- You plan to go fully off-grid β the 2100W solar input is the highest here, so you can recharge fast even on cloudy days.
- You want room to grow β the expandable capacity up to 10.24kWh means you can start small and add B2 batteries later.
ALLWEI PPS2400-3 is right for you if…
- You live in an RV or travel trailer β the built-in 30A RV port means you can plug directly into your rig without adapters.
- You need a short burst of extra power β the 3600W Power Lifting mode lets your air conditioner or microwave start up without tripping the inverter.
- You trust crowd-sourced feedback β with 2,343 reviews and a 4.4-star average, this is the most tested unit of the three.
β Who Should Skip All of These?
If you need to run a whole house for days on end β think central air, electric water heater, or a well pump that cycles all day β none of these 2048Wh units will cut it. You’re better off looking at a dual-fuel inverter generator or a whole-home battery system with at least 10kWh of capacity.
For the average camper, homeowner, or weekend warrior, my pick is the Sxtpikc P2400 β it’s the fastest to recharge, the easiest to move around, and it handles 99% of what you’ll throw at it for a fair price. Check the current price on Amazon to see if it fits your budget.
Frequently Asked Questions
Which is better for running a refrigerator β Sxtpikc P2400 or OUPES Mega 2?
I’d give the edge to the OUPES Mega 2 here because its 5400W surge handles the compressor startup spike more comfortably. A typical refrigerator draws about 600-800W running but can spike to 2000W on startup, and the OUPES has an extra 600W of headroom over the Sxtpikc’s 4800W peak. That said, the Sxtpikc’s 2048Wh capacity will still run a 100W fridge for up to 20 hours, so both will get the job done β the OUPES just feels more confident on the first startup.
Is the ALLWEI PPS2400-3 worth buying over the Sxtpikc P2400 for RV use?
Absolutely yes if you own an RV. The ALLWEI has a dedicated 30A RV port that lets you plug your trailer directly in without a bunch of adapters, plus the 3600W Power Lifting mode gives you extra oomph for starting your air conditioner. The Sxtpikc charges faster at 1800W versus 1500W, but that doesn’t matter much when you’re parked at a campsite. For RV life, the ALLWEI is the clear winner.
Which power station charges the fastest from a wall outlet?
The Sxtpikc P2400 wins this one hands down with its 1800W AC charging β it goes from zero to full in just 1.2 hours. The OUPES Mega 2 takes about 1.5 hours with its 1600W input, and the ALLWEI PPS2400-3 is the slowest at 1500W AC charging. If you frequently need to top up between power outages, the Sxtpikc saves you about 18 minutes over the OUPES and even more over the ALLWEI.
Can any of these power stations run a whole house during an outage?
Not really β at least not for long. All three have 2048Wh of capacity, which is enough to keep a fridge, a few lights, and a phone charger going for 8-12 hours, but you’re not running central air, an electric oven, or a water heater. The OUPES Mega 2 can expand up to 10.24kWh with extra B2 batteries, which gets closer to whole-home territory, but out of the box none of these will replace a 50-amp generator for a full house.
Which one is lighter and easier to carry around?
The OUPES Mega 2 is the lightest at 45.8 pounds, but it doesn’t have wheels, so you’re carrying that weight by the handle. The Sxtpikc P2400 weighs 53 pounds but comes with built-in wheels and a retractable handle, making it much easier to roll across grass or gravel. The ALLWEI is 50 pounds with no wheels, so it’s the awkward middle child. For actual portability, I’d take the Sxtpikc’s wheels over the OUPES’s lighter weight any day.
Which power station has the most output ports for charging devices?
The Sxtpikc P2400 has 16 output ports total, including two 100W USB-C ports and four 30W USB-A ports β that’s the most of the bunch. The OUPES Mega 2 has 15 ports with two 100W USB-C and four 18W USB-A, and the ALLWEI PPS2400-3 has just 11 ports with one 100W USB-C. If you’re camping with a group or running multiple devices at once, the Sxtpikc gives you the most flexibility.
My Final Verdict
The Sxtpikc P2400 is my clear winner β it charges faster than anything else at 1800W AC (0-100% in 1.2 hours), it’s the easiest to move with built-in wheels and a retractable handle, and its 4800W peak handles nearly everything you’d throw at it. The OUPES Mega 2 takes the runner-up spot for anyone who needs that extra 600W of surge power or wants to go full solar with 2100W input. The ALLWEI PPS2400-3 is your best bet if you’re living in an RV and need that 30A port.
If you’re still on the fence, ask yourself this: do you value convenience and speed, or raw power and expandability? The Sxtpikc is the grab-and-go champ, while the OUPES is the modular monster. Either way, you’re getting a solid 2048Wh LiFePO4 station that’ll last for thousands of cycles.
