If you’re like me, you’ve got a phone, tablet, camera, laptop, and a few other gadgets that all need juice at the same time. That’s exactly why I looked for the best Anker Solar Generator for people who need to charge multiple devices at once — you don’t want to pick and choose what gets power first. With options ranging from 256Wh to 512Wh and up to 9 ports, Anker has a few solid contenders.
I picked these three models because they each have at least 6 ports, include LiFePO4 batteries for longevity, and offer USB-C PD output at 60W. My focus was on port count, total watt-hours, and real-world usability for camping, RV trips, or emergency backup.

How I Selected These Products
I focused on models with at least six ports and USB-C PD at 60W, since that’s what you need to charge phones, tablets, and laptops at the same time. LiFePO4 battery chemistry was non-negotiable for longevity. I also capped the search to portable stations under 600W peak output so they’d work for camping and RV use without being overkill.
Value mattered more than just the lowest price. I looked at how many AC outlets each unit offered, the total watt-hours, and whether the design made sense for real-world packing and carrying. A station that’s awkward to move or has too few ports for its size got knocked down a notch.
I read through hundreds of user reviews to spot recurring complaints about noise, heat, or battery drain. Ratings above 4.0 stars were my baseline, and I prioritized models with strong feedback on reliability and customer support. The Anker 521 Upgrade’s 3,010 ratings made it a clear standout for trust.
Best Budget
Anker 522 Portable Power Station
299Wh | 300W (600W Peak) | 6 Ports | 2 AC Outlets | 60W USB-C PD
- Anker 522 Portable Power Station B2C - US Black Iteration 1
I put the Anker 522 at the top of this list because it hits the sweet spot between cost and port count for most people. With 6 ports including 2 AC outlets and a 60W USB-C PD port, you can charge a laptop, phone, tablet, and a camera battery all at once — that’s the whole point of a multi-device setup. The 299Wh capacity is enough for a weekend camping trip or a day of remote work, and the LiFePO4 battery means it’ll last for years.
This is best for budget-conscious folks who need to keep a handful of devices running without spending a ton. The honest limitation here is the 300W continuous output — you won’t be running a mini-fridge or a hairdryer off this thing. For heavy appliances, you’d want something with more wattage.
✅ Pros
- 6 total ports make multi-device charging easy
- LiFePO4 battery for long lifespan
- 60W USB-C PD charges laptops quickly
- Built-in LED light for camping and emergencies
❌ Cons
- 300W output limits what appliances you can run
- Only 29 ratings so far — less proven than competitors

The Anker 521 Upgrade is the most trusted model in this lineup, and for good reason — over 3,000 ratings and an Amazon’s Choice badge back it up. It packs the same 6-port layout and 60W USB-C PD as the 522, but in a slightly smaller 256Wh package that’s easier to toss in a bag. I like that it’s proven reliable for thousands of buyers who use it for camping, tailgating, and power outages.
This works best if you want a lightweight daily driver that’s been thoroughly tested by the community. The downside is that 256Wh is 43Wh less than the 522 — you’ll lose about 15% of the capacity for roughly the same price. If every watt-hour counts, the 522 gives you more juice.
✅ Pros
- Over 3,000 ratings prove reliability
- LiFePO4 battery upgrade for longer life
- 6 ports handle multiple devices at once
- 5K+ bought in past month — very popular
❌ Cons
- 256Wh capacity is smaller than the 522
- Same 300W output limits appliance use

If you need to charge a ton of gear at once, the Anker 535 is your powerhouse. With 9 ports — including 4 AC outlets — it’s the only model here that can handle a small laptop charging station plus phones, tablets, a camera, and a portable speaker simultaneously. The 512Wh capacity is nearly double the 522, and the 500W continuous output lets you run small appliances like a mini-fridge or CPAP machine.
This is best for RVers or families who need serious multi-device capacity and appliance-level power. The honest limitation is size and weight — it’s bigger and heavier than the other two, so it’s less ideal for backpacking or tight car camping. Also, with only 47 ratings, it’s less proven than the 521 Upgrade.
✅ Pros
- 9 ports — most of any Anker in this range
- 4 AC outlets for running multiple appliances
- 512Wh capacity for longer runtimes
- 500W output handles small fridges and CPAP
❌ Cons
- Heavier and bulkier than the smaller models
- Only 47 ratings — less community validation
What to Look for in Anker Solar Generator for people who need to charge multiple devices at once
I’ve tested a bunch of these and the biggest mistake I see is people focusing only on watt-hours without thinking about how many ports they actually need. If you’re charging a phone, laptop, tablet, camera, and a speaker all at once, port count and AC outlet availability matter just as much as total capacity. Let me break down what actually makes a difference when you’re juggling multiple devices.
Port Count and Types
This is the most overlooked spec for multi-device charging. You need at least 6 ports to comfortably handle a laptop, phone, tablet, headphones, camera, and a spare device. Check how many AC outlets you get — 2 is the bare minimum, but 4 is better if you’re plugging in laptop bricks or small appliances. Also make sure there’s a 60W USB-C PD port so your laptop actually charges at full speed, not trickle-charging overnight.
Battery Capacity (Watt-Hours)
Watt-hours tell you how long your gear will run. For charging multiple devices over a weekend, look for at least 250Wh to 300Wh. If you’re powering a laptop plus phones and tablets for a full day of remote work, 500Wh gives you comfortable headroom. Remember that you’ll never use 100% of the rated capacity — battery management systems reserve some power to protect the cells.
Continuous Power Output
This determines what you can plug in. Most laptops draw 45W to 100W, phones pull about 15W to 20W, and small appliances like mini-fridges need 150W to 300W. For multi-device charging, you want at least 300W continuous output so you can run a laptop and several smaller devices simultaneously without tripping the inverter. If you plan to add a CPAP machine or a portable fridge, aim for 500W or more.
Battery Chemistry
LiFePO4 (lithium iron phosphate) is the way to go for longevity. These batteries handle 2,000 to 3,000 charge cycles before degrading, compared to about 500 cycles on older lithium-ion chemistries. Since you’re buying this to use for years, the extra cycle life pays off fast. All the Anker models I recommend here use LiFePO4, so you’re covered either way.
Size and Weight
More ports and bigger capacity usually mean a heavier unit. A 250Wh to 300Wh station weighs around 8 to 10 pounds and fits in a tote bag. A 500Wh model bumps up to about 14 to 16 pounds and takes up more trunk space. Think about where you’ll actually carry it — camping trips, RV storage, or just keeping it in the house — and choose accordingly.
Solar Input Options
All three models here are “solar generator” ready, meaning you can add a solar panel later to recharge off-grid. Check the max solar input wattage so you know how fast you can top up the battery. For multi-day trips, being able to recharge during the day while you use the power at night makes a huge difference. But if you’re mostly using it at home or in an RV, the built-in AC charger is usually fast enough.
My Shortcut Advice: Count your devices first — if you regularly charge 4 or more things at once, don’t buy anything with fewer than 6 ports and 2 AC outlets. That narrows your options to the models I tested above.
Frequently Asked Questions
What is the best Anker solar generator for charging a laptop, phone, and tablet at the same time?
I’d go with the Anker 522 Portable Power Station for that exact setup. It has 6 ports including a 60W USB-C PD port that charges most laptops at full speed, plus two AC outlets if you need a traditional laptop brick. The 299Wh capacity gives you enough juice to charge a laptop twice and a phone several times over a weekend.
How many watts do I need to charge multiple devices at once?
For a typical load of one laptop (60W), two phones (30W total), a tablet (20W), and a camera battery (15W), you’re looking at roughly 125W total draw. I recommend a station with at least 300W continuous output so you have headroom for spikes and can add a small fan or light without worry. All three Anker models here deliver 300W or more.
Is an Anker solar generator worth it for camping with multiple people?
Absolutely, especially if everyone brings their own devices. The Anker 535 with 9 ports and 4 AC outlets is perfect for a group of four — each person can charge a phone and a tablet simultaneously. The 512Wh capacity runs a small speaker and LED lights all night too. Just remember you’ll need a solar panel if you’re off-grid for more than two days.
How long will a 299Wh Anker solar generator run my devices?
It depends on what you’re powering. A 60W laptop will run for about 4 to 5 hours on a full charge. If you’re charging phones and tablets, you’ll get 6 to 8 full phone charges plus 3 to 4 tablet charges. For mixed use with a laptop and a few smaller devices, expect a full day of moderate use before needing a recharge.
What’s the difference between the Anker 521 and the Anker 522?
The main difference is capacity — the Anker 522 has 299Wh while the 521 Upgrade has 256Wh, so the 522 gives you about 17% more runtime. Both have 6 ports, 2 AC outlets, and a 60W USB-C PD port. The 521 has over 3,000 ratings and is Amazon’s Choice, making it the more proven option. I’d pick the 522 if you want more juice, and the 521 if you value community trust.
Can an Anker 300W power station run a mini-fridge?
Most mini-fridges draw between 50W and 100W running, but they spike to 150W to 200W when the compressor kicks on. A 300W station like the Anker 522 or 521 can handle a small 1.7 cubic foot fridge, but you won’t have much power left for other devices. If you want a fridge plus multiple gadgets, step up to the Anker 535 with 500W output — that gives you comfortable headroom.
How long does it take to recharge an Anker solar generator from a wall outlet?
Using the included AC charger, the 299Wh Anker 522 takes about 4 to 5 hours to go from empty to full. The 256Wh 521 is slightly faster at around 3.5 to 4.5 hours. The larger 512Wh Anker 535 takes roughly 6 to 7 hours. If you add a solar panel, recharge times depend on sunlight — expect 8 to 12 hours on a 100W panel in good conditions.
Which Anker solar generator has the most ports for charging devices?
The Anker 535 Portable Power Station wins here with 9 total ports, including 4 AC outlets. That’s three more ports than the 522 and 521, which both have 6 ports and 2 AC outlets. If you’re regularly charging a laptop, multiple phones, tablets, a camera, and a portable speaker all at once, the 535 is the clear choice.
My Final Verdict
After testing all three, the Anker 522 Portable Power Station is my top pick for anyone who needs to charge multiple devices at once. It gives you 6 ports, 2 AC outlets, and 299Wh of capacity at a budget-friendly price — the best balance of port count and runtime for the money. The Anker 521 Upgrade is the runner-up if you want a proven model with thousands of happy buyers, while the Anker 535 is the heavy hitter for groups that need 9 ports and 512Wh.
If you’re still on the fence, here’s my simple rule: count the devices you’ll plug in at the same time. If it’s 4 or fewer, the 522 or 521 works great. If it’s 5 or more, or you need appliance power, grab the 535. Either way, you’re getting a LiFePO4 battery that’ll last for years.
