The 6 Best Solar-Powered Battery Packs You Can Buy Today

When you‘re out hiking, camping, or spending extended time outdoors, keeping your devices powered up can be a challenge. That‘s where solar powered battery packs come in. These portable chargers harness the power of the sun to replenish their batteries, providing a green charging option when you‘re off the grid.

While they used to be a niche product, advances in solar and battery technology in recent years have led to a wide array of excellent solar powered battery packs hitting the market. To help you find the best one for your needs, we‘ve rounded up the top 6 solar chargers you can buy today, with an in-depth look at our top pick, the Licorne solar charger.

Best Overall: Licorne 30000mAh Solar Charger
When it comes to balancing charging power, features, and price, no solar battery pack matches the Licorne. This robust 30000mAh capacity charger has enough juice to recharge a smartphone 8 times and a tablet 3-4 times before needing to be recharged itself.

Four high-efficiency monocrystalline solar panels allow the Licorne to recharge at an impressive 2 amps in direct sunlight (or 4-5 hours plugged into a power outlet). It also boasts blazing fast 3 amp charging output across both its USB-C and USB-A ports, allowing you to top up your devices in a flash. Many cheaper solar chargers are limited to slower 1 or 2 amp speeds.

The Licorne is built for the outdoors with a durable silicone cover that makes it waterproof, dustproof and shockproof. Dual LED flashlights provide illumination and an integrated compass will help you find your way.

But arguably the Licorne‘s best feature is its wireless charging pad that supports the Qi standard. This lets you charge up compatible smartphones cable-free at a respectable 10W speed. For devices that aren‘t Qi-enabled, simultaneous wired charging across the USB ports means you can power up to 3 gadgets at the same time.

While not the cheapest solar battery pack out there, the Licorne‘s excellent build quality, fast charging, and wireless capabilities earn it our top spot. It‘s an outstanding all-around performer for outdoor adventurers and emergency preparedness.

Other Great Options
If the Licorne doesn‘t quite match what you‘re looking for, here are 5 other excellent solar powered battery packs to consider:

  1. RAVPower 25000mAh Solar Power Bank
    Waterproof and rated to survive 10 foot drops, the RavPower offers outstanding 25000mAh capacity in a slim package. However, it lacks the wireless charging and USB-C port of the Licorne.

  2. Blavor 20000mAh Portable Solar Charger
    The Blavor impresses with its unique "sunflower" design that angles four solar panels for optimal sunlight collection. It‘s Qi-enabled for wireless charging but has a smaller 20000mAh battery.

  3. ZeroLemon SolarJuice 36000mAh
    For those who need maximum battery life, the ZeroLemon‘s huge 36000mAh capacity is tops, but it comes in a bulky package weighing over 1.5 pounds.

  4. Anker 24W Dual Port USB Solar Charger
    Anker‘s charger prioritizes solar collection over battery storage with three large high-efficiency panels but only a 10000mAh battery. It‘s ideal if you plan to primarily use it in direct sunlight.

  5. FEELLE 25000mAh Solar Power Bank
    FEELLE‘s 25000mAh charger offers excellent value, providing comparable battery life to pricier competitors. However, its plastic shell feels less durable.

Factors To Consider
When shopping for a solar battery charger, consider the following key factors and features:

Battery capacity – Aim for at least 10000mAh which is enough to charge most smartphones 2-3 times. Heavy users who need to charge multiple devices should look for 20000mAh or greater.

Charging speed – The output charging speed, measured in amps, determines how quickly a battery pack can charge your device. Aim for 2 amps or higher. Some of the best solar chargers now support fast charging protocols that can provide up to 18W of power.

Solar recharging speed – A battery pack‘s solar panels are rated in watts, with higher numbers able to collect more sunlight and recharge the battery faster. 5-10W is common, with some chargers now hitting 15-20W. But factors like angle to the sun also impact real-world speeds.

Size and weight – Since you‘ll likely be carrying a solar battery pack in a backpack or attaching it to gear, pay attention to its dimensions and weight. Compact models can weigh under half a pound while high capacity chargers tip the scales at 1-2 pounds.

Ruggedness – Any portable charger is prone to drops, dings, and exposure to the elements. Look for one with a durable case, ideally with rubber or silicone for impact and weather resistance. An IP67 rating means it is dust and waterproof.

Extra features – Some helpful extras to look for include multiple USB ports for charging more than one device at a time, USB-C ports for faster speeds, a flashlight, wireless charging, and an LCD screen showing battery level and charging status.

How Solar Chargers Work
Most solar powered battery packs work on the same basic principle. One or more photovoltaic panels, typically made from monocrystalline silicon, collect energy from sunlight. This solar energy is then used to charge up a lithium battery inside the pack.

You‘ll then connect your device to the battery pack via a USB cable just as you would with a traditional power bank or wall charger. The battery pack will discharge, sending power to your phone or tablet. Some also support wireless Qi charging.

When not in use or when the battery is drained, you place the solar battery pack in direct sunlight and the cycle begins again. The solar panels will recharge the internal battery which you can then use to charge your devices once more.

However, it‘s important to note that solar recharging is usually much slower than plugging into a wall outlet. Even with optimal sun exposure, filling a drained battery takes 18 hours or more for most solar chargers. Models with larger and more efficient solar panels can cut that down closer to 10 hours.

For this reason, it‘s usually best to top up the battery before heading out whenever possible and to think of solar recharging as more of an emergency backup than the primary method of keeping the battery full.

The Bottom Line
Whether you‘re a frequent camper, outdoor sports enthusiast, or just want the security of a backup power source in an emergency, solar battery packs offer a convenient and eco-friendly way to keep your devices charged when away from wall outlets.

The Licorne 30000mAh charger is our top overall pick thanks to its beefy battery, fast charging speeds, wireless capabilities and rugged construction. But any of the models highlighted here are solid options depending on your priorities and budget.

Just remember that the solar aspect of these chargers is more of a helpful add-on than a primary feature. They work best when you start with a full battery and think of the sun collection as a way to extend run times. With the right expectations, a solar battery pack can be an indispensable addition to your electronic ecosystem.
