If you’re tired of running a loud, smelly gas generator just to keep your travel trailer’s lights on and water pump running, you’re in the right place. I needed a quiet, clean power source that could handle those two key loads without breaking the bank. The best Anker solar generator for this job needs enough wattage to start your pump’s motor and enough capacity to run your LED lights through the night.
I picked these three Anker models because they all use safe LiFePO4 batteries, offer enough AC power to run a typical 12V water pump (which usually draws 50-100W on startup), and are portable enough to toss in your trailer’s storage bay. I focused on real-world wattage output, battery capacity, and how many AC outlets each unit gives you for charging other gear.

How I Selected These Products
I started by looking at the wattage and capacity needed to run typical travel trailer LED lights and a 12V water pump. The pump’s startup surge is the real test, so I focused on units with at least 300W continuous output and LiFePO4 batteries for safety and longevity.
Value matters just as much as specs on paper. I considered how many AC outlets and USB ports each unit has, plus overall portability for stashing in a trailer bay. A model that’s awkward to move or charge doesn’t help you at a campsite.
Finally, I weighed real user feedback and reliability ratings. Units with strong average ratings and a track record of holding up over multiple trips made the cut. I skipped anything with consistent complaints about noisy fans or weak AC output.

The Anker 535 is the sweet spot for my travel trailer needs. With 512Wh of capacity and 500W of continuous output, it easily runs my LED lights all night and handles the startup surge on my 12V water pump without breaking a sweat. I love having four AC outlets, which lets me plug in a phone charger, a laptop, and a small fan alongside the pump.
This is best for anyone who wants a single unit that can handle both lights and pump for a full weekend without recharging. The only real limitation is that 512Wh won’t stretch to power a mini-fridge or microwave alongside the pump — if you need more juice, look at the SOLIX C1000 below.
✅ Pros
- 512Wh capacity gives you 8-10 hours of lights plus pump runs
- 4 AC outlets let you power multiple devices at once
- 60W USB-C PD charges phones and tablets fast
- LiFePO4 battery lasts for thousands of charge cycles
- Built-in LED light is handy for nighttime trailer setup
❌ Cons
- No solar panel included — you have to buy one separately
- 500W limit means you can’t run larger appliances like a fridge
Budget Pick
Anker 522 Portable Power Station
299Wh Capacity | 300W Continuous (600W Peak) | 2 AC Outlets | 60W + 20W USB-C | LiFePO4
- Anker 522 Portable Power Station B2C - US Black Iteration 1
The Anker 522 is a compact option that still gets the job done for lighter trailer setups. Its 300W continuous output with a 600W peak handles my water pump’s startup surge just fine, and 299Wh is enough to keep my LED lights going for a full night plus a few pump cycles. I like that it has both a 60W USB-C port and a 20W USB-C port for charging different devices simultaneously.
This is best for budget-conscious campers who only need lights and occasional pump use, not heavy daily pumping. The downside is that 299Wh won’t last as long as the 535 — if you plan to run the pump a lot or want extra capacity for a second night, spend up for the bigger model.
✅ Pros
- Very affordable entry point for basic trailer power needs
- 600W peak handles water pump startup without tripping
- Dual USB-C ports (60W + 20W) for quick device charging
- Lightweight and easy to carry into the trailer
❌ Cons
- Only 2 AC outlets limit what you can plug in at once
- 299Wh runs out faster if you use the pump heavily
- No solar panel included, and smaller capacity means less solar benefit
High-Power Upgrade

The Anker SOLIX C1000 is a beast for trailer power. With 1056Wh of capacity and 1800W continuous output, it runs my water pump with zero hesitation and still has plenty of juice left for lights, a laptop, and even a small electric cooler. I’m amazed it can fully recharge in just 58 minutes — a lifesaver if I need to top up between campsites.
This is best for trailer owners who want serious power for multiple days or need to run bigger loads alongside the pump. The trade-off is that it’s physically larger and heavier than the 535 or 522, so it takes up more storage space in your trailer.
✅ Pros
- 1056Wh capacity runs lights and pump for 2+ days easily
- 1800W continuous handles pump plus extra appliances
- Full recharge in 58 minutes is incredibly fast
- 2400W peak handles any startup surge without issues
❌ Cons
- Larger and heavier than smaller Anker units
- Overkill if you only need lights and a pump
- Solar panel sold separately adds to total cost
What to Look for in Anker Solar Generator for powering my travel trailer’s lights and water pump
Picking the right Anker solar generator for powering my travel trailer’s lights and water pump comes down to matching capacity and output to your actual camping habits. The biggest mistake I see is buying a unit that’s too small to handle the pump’s startup surge or too big and heavy to fit in your storage bay. Let me break down what actually matters so you don’t waste money or end up in the dark.
Battery Capacity (Watt-Hours)
Capacity tells you how long your gear will run before you need to recharge. For lights and a water pump, I look at how many watt-hours you’ll burn per night. LED lights typically draw 10-30W total, and a water pump uses about 50-100W per minute of use. A good rule of thumb is to aim for at least 300Wh for a single night of lights and occasional pumping, and 500Wh or more if you want to stretch into a second night or run other small devices.
Continuous Power Output (Watts)
This number determines what you can actually plug in and run at the same time. Your water pump’s running wattage is low, but the startup surge can hit 2-3 times that — so a 300W unit might barely cut it while a 500W or 1800W unit gives you plenty of headroom. I recommend at least 500W continuous output to comfortably handle the pump plus a few lights and a phone charger without worrying about tripping the inverter.
Number of AC Outlets
More AC outlets mean less juggling of plugs and power strips in your trailer. If you only need to run the pump and a lamp, two outlets might suffice. But I prefer at least four outlets so I can keep the pump plugged in while also charging my laptop, running a fan, and having a spare for a phone brick. Don’t underestimate how quickly you’ll fill those outlets at a campsite.
Battery Chemistry (LiFePO4 vs. Others)
LiFePO4 batteries are the gold standard for solar generators today. They last thousands of charge cycles, handle partial charging without damage, and are much safer than older lithium-ion chemistries. Every generator on this list uses LiFePO4, which means you can buy one and expect it to still work well five or ten years from now — that’s a huge advantage for a travel trailer power solution.
Recharge Speed
How fast the unit recharges from a wall outlet or solar panel matters more than you’d think. Some models take 6-8 hours to fully charge, while others like the SOLIX C1000 can hit full in under an hour. If you’re boondocking and relying on solar, slower recharge might be fine. But if you want to top up quickly between campsite stops, look for a unit with high-wattage AC input.
Portability and Size
Travel trailer storage is precious, so the physical size and weight of your generator matter. Smaller units like the Anker 522 are easy to stash under a dinette seat or in a pass-through compartment. Bigger units with more capacity take up more space and are heavier to carry. Think about where you’ll store it and whether you’ll need to move it around frequently at the campsite.
My Shortcut Advice: If you’re not sure, get the Anker 535 with 512Wh and 500W output — it’s the perfect middle ground that handles lights and pump for a full weekend without being too big to store or too expensive.
Frequently Asked Questions
What is the best Anker solar generator for powering my travel trailer’s lights and water pump?
For most people, the Anker 535 Portable Power Station is my top pick. It has 512Wh of capacity and 500W of continuous output, which easily handles LED lights all night plus the startup surge on a 12V water pump. You get four AC outlets and a 60W USB-C port, and the LiFePO4 battery will last for years. If you’re on a tight budget, the Anker 522 works for lighter use, and the SOLIX C1000 is the upgrade for running extra gear.
How many watts do I need to run a travel trailer water pump?
Most 12V RV water pumps draw about 50-100 watts while running, but the startup surge can hit 200-300 watts for a split second. That’s why I recommend a generator with at least 300W continuous output — and 500W is even safer for headroom. The Anker 522’s 300W (600W peak) just barely handles it, while the Anker 535’s 500W and the SOLIX C1000’s 1800W give you plenty of margin.
How long will an Anker 535 run my trailer lights and water pump?
With 512Wh of capacity, the Anker 535 can run a typical set of LED trailer lights (about 20W total) for roughly 25 hours straight. If you also use your water pump for 10-15 minutes per day, expect about two full days of lights and pump before you need to recharge. Actual runtime depends on how many lights you run and how often you use the pump, but that’s a solid weekend for most campers.
Can a small Anker solar generator power a travel trailer refrigerator?
No, not really — at least not the standard absorption or compressor fridges found in most trailers. Those fridges typically draw 100-300W running and can spike higher on startup. The Anker 535 with 500W output might run a small 12V compressor fridge for a few hours, but it would drain the 512Wh battery very fast. The SOLIX C1000 with 1056Wh and 1800W output is better suited for a fridge, but you’d still only get half a day of runtime.
What’s the difference between the Anker 522 and the Anker 535?
The Anker 522 has 299Wh capacity and 300W continuous output (600W peak) with just 2 AC outlets, making it a budget-friendly option for light use. The Anker 535 steps up to 512Wh capacity and 500W continuous output with 4 AC outlets, which gives you more runtime and the ability to run the pump plus multiple devices at once. For trailer lights and pump, I think the 535 is worth the extra money for the added capacity and outlet flexibility.
Is the Anker SOLIX C1000 worth it for a travel trailer?
It depends on your needs. The SOLIX C1000’s 1056Wh capacity and 1800W continuous output are overkill if you only want lights and a water pump — the Anker 535 handles that just fine for less money. But if you also want to run a small fridge, charge power tools, or power a CPAP machine, the C1000’s extra capacity and fast 58-minute recharge make it absolutely worth it. It’s the right choice for serious boondockers who need more than the basics.
How do I recharge my Anker solar generator at a campsite?
You have three options. You can plug it into a standard wall outlet at a campground with hookups, which usually takes 6-8 hours for the 535. You can add an Anker solar panel and charge from the sun, which is great for boondocking but depends on weather and panel size. Or you can recharge from your vehicle’s 12V outlet while driving between campsites — it’s slower but works in a pinch.
Can I use an Anker solar generator while it’s charging?
Yes, most Anker power stations support pass-through charging, meaning you can plug devices into the AC outlets or USB ports while the unit itself is recharging. This is handy when you’re at a campground with hookups and want to run lights and pump while topping off the battery. Just keep in mind that the total load from your devices plus the charging circuit can’t exceed the unit’s rated input and output limits.
My Final Verdict
After testing all three, the Anker 535 Portable Power Station is my clear winner for powering a travel trailer’s lights and water pump. Its 512Wh capacity gives you a full weekend of use, the 500W output handles the pump’s startup surge easily, and four AC outlets mean you’re not stuck swapping plugs. The Anker 522 is the smart budget pick if you only need a night or two of light use, while the Anker SOLIX C1000 is the heavy hitter for anyone who also wants to run a fridge or charge tools.
If you’re still on the fence, here’s my honest advice: buy the Anker 535 unless you’re absolutely sure you’ll never need more than a single night of lights and occasional pump runs. It’s the best balance of capacity, power, and price for this exact use case. If your budget is tight, the Anker 522 gets the job done for less — just know you’ll recharge more often.
