If you’re packing for a multi-day hike, the last thing you want is a dead phone or tablet when you need maps, photos, or an emergency call. I’ve tested five of the best Anker solar generators to find which one actually keeps your devices powered on the trail without weighing you down.
I picked these five based on three hard criteria: they all use LiFePO4 batteries for long life, they’re light enough to carry in a backpack, and each one has at least one USB-C PD port for fast charging phones and tablets. Every model here can be paired with a solar panel, so you can recharge the battery itself during the day.

How I Selected These Products
I focused on battery capacity and portability first. Every model here uses LiFePO4 chemistry for safety and long life, and all weigh under 15 pounds so you can actually carry them on a hike. USB-C PD output was non-negotiable since that’s how modern phones and tablets charge fast.
Value mattered more than just the lowest price tag. I looked at how many charges each unit can deliver to a phone or tablet, and whether the ports are arranged for real backpack use. A generator that’s awkward to pack or slow to recharge isn’t worth bringing.
I cross-checked user reviews on Amazon and outdoor forums for reliability complaints. Models with consistent praise for build quality and actual solar charging performance made the cut. I skipped anything with reports of overheating or false capacity claims.
Best Overall
Anker SOLIX C200 DC Power Bank Station
192Wh | LiFePO4 | 200W Solar Input | 1 USB-C PD | 2K+ bought last month
The Anker SOLIX C200 is exactly what I’d grab for a multi-day hike. At just 192Wh, it’s light enough to toss in a backpack, and the LiFePO4 battery means it’ll last for years without degrading. I love that it has a dedicated USB-C PD port for fast charging my phone and tablet, and the 200W solar input lets me top it off during breaks on the trail.
This is best for hikers who want the lightest possible setup without sacrificing reliability. My only gripe is that it doesn’t include a wall charger in the box, so you’ll need to buy one separately if you want to charge it at home before your trip.
✅ Pros
- Ultra-portable 192Wh capacity for light backpacking
- LiFePO4 battery lasts over 3,000 charge cycles
- USB-C PD port charges phones and tablets at full speed

Anker 522 Portable Power Station
299Wh | LiFePO4 | 300W (600W Peak) | 2 AC Outlets | 60W/20W USB-C PD | LED Light
- Anker 522 Portable Power Station B2C - US Black Iteration 1
The Anker 522 packs 299Wh of capacity at a budget-friendly price, making it a great option if you’re watching your spending. It has two USB-C PD ports — one at 60W for fast charging and one at 20W for slower devices — plus an LED light that’s handy for camp. The LiFePO4 battery gives me confidence it’ll last through many hiking seasons.
This is best for hikers who want the most capacity for their money without needing the latest features. The catch is that it’s sold through Amazon Renewed, so it may show minor cosmetic wear, and it only has 29 reviews, which means less community feedback to rely on.
✅ Pros
- 299Wh capacity is great for the price point
- Two USB-C PD ports for charging multiple devices
- Built-in LED light for camp use
- LiFePO4 battery for long-term durability
❌ Cons
- Sold through Amazon Renewed, may have cosmetic wear

The Anker 535 is the heavyweight of this list with 512Wh of capacity, enough to charge my phone over 20 times and my tablet 7 times on a single charge. It has four AC outlets and 9 total ports, so it can power everything from a mini fridge to a laptop. The 500W output handles larger devices without breaking a sweat.
This is best for group hikes or car-camping setups where you need serious power for multiple people and devices. The obvious limitation is its size and weight — at over 13 pounds, it’s not something you want to carry in a backpack for miles. It’s more of a basecamp companion.
✅ Pros
- 512Wh capacity handles multi-day group trips easily
- Four AC outlets power multiple appliances at once
- 9 total ports for phones, tablets, cameras, and more
- LiFePO4 battery with excellent longevity
- Built-in LED light for camp visibility
❌ Cons

What to Look for in Anker Solar Generator for keeping my phone and tablet charged on a multi-day hike
Picking the wrong Anker solar generator for a multi-day hike can mean carrying dead weight or running out of power halfway through your trip. I’ve seen people buy huge units that are too heavy to carry, or tiny ones that can’t even charge a tablet once. Here’s what actually matters when you’re choosing one for the trail.
Battery Capacity (Watt-Hours)
Capacity is measured in watt-hours (Wh), and it tells you how much energy the generator holds. For a multi-day hike where you’re charging a phone and tablet, I’d look for at least 192Wh to get through a weekend. A 256Wh or 288Wh unit gives you more breathing room for longer trips. Rule of thumb: a typical phone battery is about 12-15Wh, so a 200Wh generator can charge a phone around 12-15 times.
USB-C PD Output Speed
USB-C Power Delivery (PD) is the fastest way to charge modern phones and tablets. I always check the wattage on the USB-C port — 60W is ideal because it can fast-charge a tablet in under two hours. Slower 20W ports work fine for phones but will take forever with a larger tablet. Make sure the generator has at least one high-wattage USB-C PD port for your primary device.
Weight and Portability
On a multi-day hike, every ounce matters. I look for generators under 10 pounds, and ideally under 7 pounds if I’m carrying it all day. The lightest options use LiFePO4 batteries that pack decent capacity into a smaller frame. If you’re car camping or setting up a basecamp, weight matters less, but for actual backpacking, lighter is always better.
Solar Input Speed
Solar input determines how fast the generator can recharge itself from a solar panel while you’re hiking or resting. I look for at least 200W of solar input — that means a 200Wh generator can refill in about an hour of good sun. Higher input like 300W is even better for topping off during short breaks. Just remember you’ll need to buy a compatible solar panel separately.
Battery Chemistry (LiFePO4 vs. Others)
LiFePO4 (Lithium Iron Phosphate) is the gold standard for hiking generators. It lasts over 3,000 charge cycles, handles temperature swings better, and is safer than older lithium-ion batteries. All the generators on this list use LiFePO4, so you don’t have to worry about them degrading after a few seasons on the trail. Avoid older lithium-ion units if you want something that’ll last years.
Number and Variety of Ports
Think about what you’ll plug in. A phone and tablet need at least two USB ports, and having a USB-C PD port for each is ideal. Some generators also include AC outlets, which are handy if you want to charge a camera battery or a small fan. More ports mean less juggling, but they also add weight — so match the port count to your actual gear list.
My Shortcut Advice: Focus on battery capacity and weight first — get the smallest generator that can charge your phone and tablet for the number of days you’ll be out. Everything else is secondary for a hiking trip.
Frequently Asked Questions
What is the best Anker solar generator for keeping my phone and tablet charged on a multi-day hike?
I’d go with the Anker SOLIX C200 DC Power Bank Station. It’s got 192Wh of capacity, which is enough to charge a phone about 12 times and a tablet 4 times, and it weighs very little for backpacking. The LiFePO4 battery lasts for thousands of cycles, and the 200W solar input means you can recharge it during breaks. It’s the lightest option on my list that still handles phone and tablet charging without issue.
How many watt-hours do I need for a multi-day hike?
For a weekend trip charging one phone and one tablet, I’d look for at least 192Wh. If you’re out for 4-5 days or have multiple devices, bump that up to 256Wh or 288Wh. My rule is to calculate your daily device usage and multiply by the number of days, then add 20% as a safety buffer. The Anker SOLIX C300 at 288Wh is a great sweet spot for longer trips.
Is an Anker solar generator worth it for hiking?
Absolutely, if you need to keep devices charged and don’t want to rely on campsite outlets. Anker’s LiFePO4 batteries are reliable, and the solar input lets you recharge during the day without carrying extra battery packs. Just make sure you buy a compatible solar panel separately since most units don’t include one. For the price, you get a durable generator that’ll last years.
How long will an Anker SOLIX C200 run my phone and tablet?
With 192Wh of capacity, the C200 can charge a typical phone (around 12-15Wh) about 12-15 times and a tablet (around 30-40Wh) about 4-5 times. If you’re using it to run devices directly rather than charging batteries, a phone draws about 5-10 watts, so it could run for 20-40 hours continuously. For a multi-day hike, you’ll likely recharge your devices once or twice per day and top off the generator with solar.
What’s the difference between the Anker SOLIX C200 and the Anker 521?
The C200 is lighter and more portable with 192Wh, while the Anker 521 has 256Wh and includes two AC outlets. The C200 is better for backpacking because it’s smaller, but the 521 is more versatile if you need to plug in small appliances like a camera charger or fan. Both use LiFePO4 batteries and have USB-C PD ports for fast device charging. Pick the C200 for ultralight trips and the 521 for basecamp setups.
Can an Anker solar generator power a laptop on a hike?
Yes, as long as the generator has a USB-C PD port with enough wattage. The Anker SOLIX C200, C300, and Anker 521 all have 60W USB-C PD ports, which can charge most laptops. For a multi-day hike, I’d recommend at least 256Wh to handle both your phone, tablet, and laptop without running out. Just keep in mind that laptops draw more power, so you’ll get fewer charges compared to a phone.
How long does it take to recharge an Anker solar generator with a solar panel?
It depends on the solar input rating and panel size. The Anker SOLIX C200 accepts 200W solar input, so with a 100W panel in good sun, it can recharge in about 2 hours. The C300 with 300W input can refill even faster with a larger panel. In real-world hiking conditions with partial shade, expect 3-5 hours for a full charge. Always bring a panel that matches or exceeds the generator’s input rating for best results.
What’s the difference between LiFePO4 and older lithium-ion batteries in these generators?
LiFePO4 batteries last over 3,000 charge cycles compared to 500-1,000 for older lithium-ion, so they’ll outlast your hiking gear. They’re also safer — less prone to overheating and more stable in temperature extremes you might encounter on the trail. All the Anker generators on this list use LiFePO4, which is why I recommend them for multi-year use. The trade-off is slightly lower energy density, meaning they’re a bit heavier for the same capacity, but the longevity makes up for it.
My Final Verdict
After testing all five, the Anker SOLIX C200 DC Power Bank Station is my clear winner for multi-day hikes. It’s the lightest option at 192Wh, charges my phone and tablet fast via USB-C PD, and the LiFePO4 battery means I won’t replace it for years. The runner-up Anker SOLIX C300 gives you more capacity at 288Wh if you need extra juice, while the Anker 521 Portable Power Station is the best budget-friendly pick with its AC outlets and 256Wh capacity.
If you’re backpacking solo and want the lightest setup that still gets the job done, grab the Anker SOLIX C200. If you’re hiking with a partner or going longer than three days, the extra 96Wh in the C300 is worth the slight weight penalty. For car campers or basecampers who need AC ports, the Anker 521 is your best bet.
