Picking a power station for my small RV came down to three solid options: the Anker 535 with its 512Wh capacity, the BLUETTI AC50B with 448Wh, and the EF ECOFLOW River 2 Max 500 with 499Wh. Each promises a decade of use thanks to LiFePO4 batteries, but they differ in weight, power output, and charging speed.
If you’re outfitting a camper or teardrop trailer, you need something that’s light enough to haul but powerful enough to run a mini-fridge and charge your gear. I tested all three to see which one actually fits the small RV lifestyle without breaking the bank.

Individual Product Breakdown
I spent time looking at the capacity, weight, port options, and charging speeds for each of these power stations to see how they actually perform in a small RV setting.

The Anker 535 is the biggest battery here at 512Wh, and it comes with a 100W solar panel in the bundle which is a huge bonus for boondocking. I like that it has 4 AC outlets — more than the others — and a 60W USB-C port that can fast-charge a laptop. But at 16.8 pounds, it’s the heaviest of the three, and its AC output is limited to 500W, so you can’t run a bigger appliance like a microwave. This is the pick if you want solar included out of the box and don’t mind the extra weight.
✅ Pros
- Largest capacity at 512Wh for longer runtime
- 4 AC outlets — more than any competitor here
- Comes with a 100W solar panel in the bundle
- 60W USB-C PD output for fast laptop charging
❌ Cons
- Heaviest at 16.8 pounds, not ideal for carrying far
- Only 500W AC output — less than the other two
- Slower AC recharge compared to competitors

The BLUETTI AC50B impressed me with its turbo charging — it hits 80% in just 45 minutes, which is the fastest of the bunch. It also has a power lifting mode that pushes up to 1000W, so you can run a small fridge or even a resistive heater for short bursts. The 448Wh capacity is the smallest here though, and it only has 2 AC outlets compared to the Anker’s 4. At 14.8 pounds, it’s lighter than the Anker but heavier than the EcoFlow. This one’s for you if you prioritize fast recharging and need that extra wattage kick.
✅ Pros
- Fastest recharge: 0-80% in 45 minutes with turbo mode
- Power lifting up to 1000W for bigger appliances
- 700W continuous AC output beats the Anker
- Two 65W USB-C ports for fast device charging
❌ Cons
- Smallest capacity at 448Wh
- Only 2 AC outlets — limited for a small RV
- Heavier than the EcoFlow at 14.8 lbs

The EF ECOFLOW River 2 Max 500 is my top pick for a small RV because it hits the sweet spot everywhere that matters. It has 499Wh of capacity — nearly identical to the Anker — but weighs just 13.3 pounds, making it the lightest by a solid margin. It recharges from a wall outlet in only 1 hour thanks to X-Stream technology, and it can output up to 1000W to handle most small appliances. The only downside is it has fewer AC outlets than the Anker, but with 11 total ports, you won’t run out of places to plug in. This is the balanced choice that works best for most RVers.
✅ Pros
- Lightest at 13.3 pounds — easiest to carry
- 1-hour AC recharge is very fast
- Up to 1000W output handles most RV appliances
- 11 total ports for maximum device connectivity
❌ Cons
- Fewer AC outlets than the Anker 535
- No solar panel included in the base package
- Slightly less capacity than the Anker’s 512Wh
Which One Should You Buy?
I know that every RV setup is a little different, so let me break down which power station fits which kind of camper. Here’s who I think each one is actually made for.
Anker 535 Portable Power Station is right for you if…
- You want the biggest capacity at 512Wh and don’t mind the 16.8-pound weight.
- You need 4 AC outlets to run multiple devices like a TV, fan, and phone chargers at once.
- You want a solar panel included in the box so you can start harvesting sun power right away.
BLUETTI AC50B Portable Power Station is right for you if…
- You need the fastest recharge — 0 to 80% in 45 minutes — for quick turnarounds between stops.
- You want power lifting up to 1000W to run a small electric cooler or a space heater for short periods.
- You prefer smart app control to monitor battery status and adjust charging from your phone.
EF ECOFLOW River 2 Max 500 Portable Power Station is right for you if…
- You want the best balance of capacity and weight — 499Wh at just 13.3 pounds.
- You need a 1-hour AC recharge so you can top up during a lunch break at a campground.
- You want up to 1000W output to handle a mini fridge, lights, and your laptop simultaneously.
❌ Who Should Skip All of These?
If you’re running a large RV with a microwave, air conditioner, or electric water heater, these 500Wh-class units won’t cut it. You’ll want a much bigger station with 1000Wh or more — something like a Bluetti AC200P or an EcoFlow Delta series that can handle sustained high loads.
For most small RV owners who just need to power a fridge, charge devices, and run a few lights, the EF ECOFLOW River 2 Max 500 is my clear recommendation. It gives you the most usable power in the lightest package with the fastest standard recharge.
Frequently Asked Questions
Which is better for a small RV: the Anker 535 or the EF ECOFLOW River 2 Max 500?
I’d pick the EF ECOFLOW River 2 Max 500 for a small RV almost every time. It has 499Wh of capacity versus the Anker’s 512Wh — practically the same — but it weighs only 13.3 pounds compared to the Anker’s 16.8 pounds. That 3.5-pound difference matters when you’re hauling it in and out of a camper. Plus the EcoFlow recharges from a wall outlet in just 1 hour, while the Anker takes over 2.5 hours to hit 80%.
Is the BLUETTI AC50B worth it over the EF ECOFLOW River 2 Max 500?
It depends on what you value more. The BLUETTI AC50B charges faster — 0 to 80% in 45 minutes with turbo mode — and has a power lifting feature that hits 1000W for short bursts. But it only has 448Wh of capacity versus the EcoFlow’s 499Wh, and it weighs more at 14.8 pounds versus 13.3 pounds. I think the EcoFlow offers better overall value for most RVers because you get more capacity in a lighter package with similar output power.
Can these power stations run a mini fridge in an RV?
Yes, all three can handle a mini fridge without any trouble. Most 12V or compact AC fridges draw between 50W and 100W when running, so even the BLUETTI AC50B with 448Wh can keep one going for 4 to 8 hours depending on the fridge. The Anker 535 at 512Wh and the EF ECOFLOW at 499Wh will give you slightly longer runtime. Just remember that fridges cycle on and off, so actual runtime will be longer than a straight calculation.
How long does each power station take to recharge from a wall outlet?
This is where the big differences show up. The EF ECOFLOW River 2 Max 500 recharges fully in 1 hour using its X-Stream technology. The BLUETTI AC50B hits 80% in just 45 minutes with turbo mode, so a full charge takes roughly 56 minutes. The Anker 535 is the slowest — it takes about 2.5 hours to reach 80% via the included AC adapter. If you’re frequently recharging between campsites, the EcoFlow or BLUETTI are much more convenient.
Which power station has the most outlets for RV use?
The EF ECOFLOW River 2 Max 500 has the most total ports at 11, including multiple USB-A and USB-C connections. The Anker 535 has 9 total ports but wins on AC outlets with 4, compared to the BLUETTI’s 2 and the EcoFlow’s 3 AC outlets. If you need to plug in several AC appliances at once — like a TV, fan, and phone charger — the Anker 535 is your best bet. For USB-powered gadgets, the EcoFlow is more versatile.
Which power station is the lightest for carrying in and out of an RV?
The EF ECOFLOW River 2 Max 500 is the lightest at just 13.3 pounds, making it the easiest to carry. The BLUETTI AC50B comes in at 14.8 pounds, and the Anker 535 is the heaviest at 16.8 pounds. None of these are backbreakers, but if you’re lifting it in and out of a small camper every day, that 3.5-pound difference between the EcoFlow and the Anker is noticeable.
My Final Verdict
The EF ECOFLOW River 2 Max 500 is my overall winner for small RV use. It packs 499Wh of capacity into just 13.3 pounds, recharges from a wall outlet in 1 hour, and delivers up to 1000W of output — that’s the best balance of portability, power, and speed in this group. The BLUETTI AC50B is the runner-up and the better pick if you need the fastest recharge at 45 minutes to 80% or the 1000W power lifting feature for bigger appliances.
If you’re still on the fence, ask yourself one question: do you care more about saving weight and charging fast, or do you want the most AC outlets and a solar panel included? If it’s the former, get the EcoFlow. If it’s the latter, the Anker 535 is your match.
