A solar power bank lets you recharge your phone, tablet, or other devices anywhere the sun shines, with no outlet required. The best ones charge fast, hold a meaningful amount of power, and survive the bumps and weather of outdoor use. But solar panels add bulk and cost, and a cheap solar panel on an otherwise good power bank can make the whole product frustrating to use. Knowing which ones are worth buying takes some research.

We’ve looked at what’s currently available and selected eight solar power banks that deliver genuine value, from ultra-compact everyday options to high-capacity units for extended backcountry trips.

Our Top Picks

8 Best Solar Power Banks

1. Anker PowerCore Solar 20000

Anker’s reputation for build quality and battery reliability is well established, and the PowerCore Solar 20000 backs that reputation with a 20,000mAh capacity, fast charging output, and a solar panel that actually contributes meaningfully to charging rather than just existing as a marketing feature. The solar input reaches up to 700mAh under ideal conditions, which translates to roughly 50 hours of full sun to charge from empty via solar alone. That sounds long, but for topping off a unit that’s already mostly charged from a wall outlet, it works well on a daypack or roof of a tent.

The 18W USB-C Power Delivery output charges modern laptops and tablets at a useful rate, and the 12W USB-A port handles everything else. A built-in flashlight is a nice addition for camping use.

Build quality is excellent. The rubberized outer shell absorbs impacts and the whole unit has an IPX5 water resistance rating, which is sufficient for rain and splashes though not submersion. This is the power bank to buy if you want Anker’s quality assurance behind the solar panel branding.

For multi-day hiking or camping where you want to partially solar-supplement grid-charged capacity, it’s an excellent choice. Don’t expect solar to be your only charging source unless you have a lot of direct sun and patience.

Features

• 20,000mAh capacity
• 18W USB-C Power Delivery output
• Solar input up to 700mAh
• IPX5 water resistant
• Built-in LED flashlight
• Dual USB-A + USB-C output ports

2. BLAVOR Solar Power Bank 20000mAh

The BLAVOR is a feature-packed solar power bank that consistently ranks highly for the combination of wireless charging, high capacity, and decent solar panel performance. The 20,000mAh lithium polymer battery can charge a typical smartphone 4 to 5 times, and the wireless charging pad on the back charges Qi-compatible devices without cables, which is a convenience feature that few competitors at this price offer.

The two solar panels (front and back) produce better solar input than single-panel designs, and the micro-suction surface allows you to stick it to a smooth surface like a tent window for hands-free solar charging. The IP66 waterproof rating is genuinely impressive for the price, making it one of the more water-resistant options on this list.

Output includes USB-C PD, two standard USB-A ports, and the wireless pad simultaneously if needed. An SOS flashlight mode with strobe is a practical safety addition. The only trade-off is that all this capability adds weight and bulk, making it less ideal for ultralight travel.

If you want maximum features in a solar power bank and don’t mind the size, the BLAVOR is hard to beat for the money.

Features

• 20,000mAh capacity
• Wireless Qi charging output
• Dual solar panels (front and back)
• USB-C PD + dual USB-A outputs
• IP66 waterproof
• SOS flashlight with strobe mode

3. Hiluckey Solar Charger 25000mAh

The Hiluckey Solar Charger earns its spot with the highest capacity on this list, 25,000mAh, and four solar panels that provide the best solar input of any consumer-grade power bank we’ve seen. Under good conditions, the quad-panel design can push 1.5 to 2W of solar input, which meaningfully reduces dependence on wall-outlet top-ups during multi-day outdoor trips.

The 25,000mAh capacity is enough to charge most smartphones 6 to 7 times. It has three USB-A outputs and one USB-C input, though the lack of USB-C output is a limitation for users with newer devices that expect fast USB-C charging. Most phones still charge fine via USB-A, but it’s worth knowing before buying.

The IPX5 water resistance and rubberized frame make it outdoor-durable. The four-panel array is larger than single-panel units but the extra solar surface area is functional, not decorative. If solar supplementation matters to you on extended trips, the quad panels make a real difference compared to single-panel competitors.

The trade-off is size and weight. This is one of the heavier options on the list. It lives comfortably in a pack but isn’t something you’d carry in a pocket.

Features

• 25,000mAh capacity
• Four solar panels for maximum input
• Three USB-A + one USB-C input
• IPX5 water resistant
• LED flashlight
• Carabiner clip included

4. ADDTOP Solar Power Bank 26800mAh

The ADDTOP pushes capacity even further, to 26,800mAh, which is about as high as you’ll find in consumer solar power bank designs without crossing into generator territory. For a group of campers sharing one power bank, or for charging a tablet multiple times, the capacity gives you real headroom.

It charges via solar, micro-USB, or USB-C, which gives you input flexibility in different situations. Two USB-A outputs and one USB-C output cover most device types. The solar input is a single panel and produces around 800mAh under ideal conditions, so it’s best used as a supplement to wall charging rather than a primary source.

The drop-resistant rubber housing and IP65 waterproofing give it solid outdoor credentials. An integrated LED flashlight rounds out the feature set. At this capacity, the ADDTOP is a solid pick for base camp use where weight is less of a concern than having enough power to keep multiple devices going over several days.

It’s a chunky unit. Don’t buy this for day hiking where you want to travel light. It’s a camp-stay and car-camping power bank, not a trail power bank.

Features

• 26,800mAh capacity
• Tri-input: solar, micro-USB, USB-C
• USB-A x2 and USB-C output
• IP65 waterproof
• Drop-resistant rubber housing

5. BigBlue 3 USB Ports Solar Charger

The BigBlue is different from the others on this list. It’s not a power bank. It’s a direct solar panel charger with no internal battery, designed to charge your devices directly from the sun while you’re stationary. You hook your phone to it, set it in the sun, and it charges as fast as the sun allows.

The advantage of this design is weight and simplicity. At 21 watts of solar output, it charges phones fast on a sunny day, comparable to a standard wall outlet. There’s no heavy battery to carry, which makes it the ultralight choice for activities where you can stay in the sun while charging.

It folds into a compact panel sleeve and clips to a pack with the included carabiner. Three USB ports charge multiple devices simultaneously. A built-in ammeter shows you actual charging current so you can optimize panel angle.

The limitation is obvious: no battery means no charge stored. If you need power after dark or during overcast stretches, you need a separate battery. It’s a companion product for solar storage, not a standalone solution.

Features

• 21W direct solar output (no internal battery)
• Three USB-A ports
• Foldable panel design, carabiner clip
• Built-in ammeter for panel optimization
• Lightweight at 21 ounces

6. Feeke Solar Power Bank 10000mAh

The Feeke is the compact choice on this list. At 10,000mAh, it’s half the capacity of most other options here, but it’s also significantly lighter and easier to carry in a jacket pocket or small bag. For a day hike or weekend trip where you mostly need to top off one phone, the 10,000mAh capacity is often plenty.

The single solar panel is appropriately sized for the smaller unit, and the IP67 waterproof rating is actually higher than many larger competitors. The USB-C output charges modern phones at a reasonable rate, and the standard USB-A handles everything else.

It’s honestly better looking than most solar power banks, with a compact rectangular form factor that doesn’t look conspicuously outdoor-gear. Battery LED indicators show remaining charge clearly. For everyday carry with occasional solar supplementation, this size class makes more practical sense than lugging a 20,000mAh unit.

For week-long trips where you need to charge multiple devices repeatedly, step up to a larger capacity. But for most day-to-day outdoor use, the Feeke hits a nice balance of portability and capability.

Features

• 10,000mAh capacity
• IP67 waterproof
• USB-C + USB-A outputs
• Compact pocket-friendly size
• LED battery indicator

7. Dizaul Solar Charger 5000mAh

The Dizaul is the ultra-compact option, a 5,000mAh solar power bank small enough to fit in a shirt pocket. It charges one smartphone once, which sounds limiting until you realize most people’s biggest fear is losing their last 20 percent of battery, not needing five full charges. As an emergency backup that clips to a keyring or bag, the Dizaul is genuinely useful.

The solar panel charges the battery slowly, but that’s the trade-off for the small form factor. Clip it to the outside of a bag on a sunny day and you’ll pick up enough charge for an emergency top-off. It’s not designed for serious power needs, but it earns its place as a lightweight emergency device.

The IP65 rating and rugged outer casing make it more weather-resistant than its diminutive size might suggest. For hikers who want an absolute minimum weight emergency option, the Dizaul makes sense.

Features

• 5,000mAh capacity
• Ultra-compact pocket size
• IP65 weatherproof
• Single USB-A output
• Carabiner attachment point

8. iWALK Small Solar Power Bank 9000mAh

The iWALK fills a niche: a compact solar power bank with a built-in lightning connector for iPhone users, eliminating the cable entirely for Apple device charging. If you exclusively use iPhones and want the most convenient possible solution, plugging your phone directly into the power bank without any cable is genuinely useful.

The 9000mAh capacity is enough for two to three phone charges. Solar input is modest, typical for this size class, but the integrated lightning plug is the actual selling point. Android users have no reason to choose this over other options, but iPhone users who forget cables regularly will appreciate it.

Build quality is decent. The compact form factor is similar to the Feeke but with the added value of the built-in connector. If the built-in plug doesn’t apply to your devices, look elsewhere on this list.

Features

• 9,000mAh capacity
• Built-in lightning connector for iPhone
• USB-A output port
• Solar charging panel
• Compact form factor

Solar Power Bank Buying Guide

Key Takeaways

• Solar charging is best used as a supplement to grid charging, not a replacement. Wall charging fills the battery; solar extends it on the go.
• Capacity in mAh determines how many times you can charge your devices. A 10,000mAh bank charges a 3,000mAh phone roughly 3 times accounting for conversion losses.
• USB-C PD output is the fastest charging option for modern smartphones and tablets.
• More solar panels mean more input, but also more weight and bulk.
• IP65 or higher water resistance is important for outdoor use.

Understanding mAh and Real-World Capacity

The mAh rating tells you how much energy the internal battery stores. However, due to conversion losses when charging devices, expect about 60 to 70 percent of the rated capacity to actually reach your device. A 20,000mAh power bank typically delivers 12,000 to 14,000mAh to a device in practice. Factor this in when estimating how many charges you’ll get.

How Fast Do Solar Panels Actually Charge?

Consumer solar power bank panels typically produce 0.5 to 2 watts under ideal direct-sun conditions. A 20,000mAh battery needs roughly 100 watt-hours to fill from empty. At 1 watt of solar input, that’s 100 hours of direct sun. Solar is genuinely useful for slowing the depletion of a partially charged bank during outdoor use, not for charging a dead bank from scratch. Set realistic expectations and you’ll be happy with solar power banks. Expect too much and you’ll be disappointed.

What to Look for in Water Resistance

IP65 means protected against dust and water jets. IP67 means it can be submerged in 1 meter of water for up to 30 minutes. For hiking and camping use where rain exposure is the primary concern, IP65 is sufficient. For kayaking or activities near water, IP67 is worth the premium.

Case Study: Phone Power on a 5-Day Backpacking Trip

Background

A backpacker planning a 5-day solo trip in the Sierra Nevada wanted to keep their phone charged for navigation, photography, and emergency communication without carrying a charging cable for a wall outlet they wouldn’t have access to.

What They Did

They carried a Hiluckey Solar Charger 25,000mAh fully charged from a wall outlet before departure. Each morning, they clipped it to the top of their pack with the solar panels facing up. The mountain sun provided roughly 1 to 1.5 watts of solar input during the 8 to 10 hours of hiking each day, adding approximately 10 to 15 percent charge daily through solar alone. Their phone consumed about 15 percent of the power bank per day with moderate use.

Results

After 5 days, the power bank still had 30 percent remaining. The solar supplementation meaningfully extended their window. They returned with phone fully charged and emergency power still available. The extra weight of the high-capacity unit (about 14 ounces vs a compact option) was worth it for 5 days of full-featured phone use.

Expert Insights From Our Solar Panel Installers About Solar Power Banks

One of our senior solar panel installers with over 11 years of experience in solar technology notes: “People ask me all the time whether solar power banks actually work. The honest answer is yes, but not the way most buyers assume. The solar panel on a power bank is sized for portability, not maximum output. Think of it as a trickle charger that works while you’re outdoors, not a fast charger that replaces plugging in. Buy a well-reviewed brand with a solid battery and treat the solar panel as a useful bonus for extending charge on long outdoor days, and you’ll be happy. Expect it to replace your wall outlet and you’ll be disappointed.”
