Working remotely using a laptop is becoming more and more common, and with it comes the challenge of keeping a computer powered up when electric outlets are scarce. Whether at an outdoor café, camping in the wilderness, on a road trip, living off-grid, or in a sudden power-outage situation, a portable solar laptop charger is a handy device to have.

Most portable solar laptop chargers function as mini power stations capable of charging other electronics like cell phones, cameras, drones, and tablets – to name a few. Now, with more options than ever to choose from, we’ve sorted through the latest solar devices to find our favorites.

Here are the six best portable solar laptop chargers.

Inside is 25 liters of storage, a dedicated padded 15-inch laptop sleeve for added protection, and plenty of interior pockets.

The new larger capacity, 88-watt hour battery comes with USB-C to charge the latest devices. The battery can be recharged with the AC adapter or with the 10-watt solar panel that’s built into the rear of the backpack. It takes about six hours to fully charge a laptop.

Final Verdict

Our top pick for a portable solar laptop charger is the Jackery Power Outdoors (view at Home Depot) unit for its reasonable price and high functionality, but if you’re looking for a cost-friendly option, the Expert Power Station’s S200 (view at Amazon) is an affordable, lightweight choice for charging laptops and cell phones on the go. If you’d like to splurge on something more powerful to charge laptops as well as larger electronics, the River Max Solar Generator Kit (view at Earth Products) is a worthwhile investment.

Good to Know

While some portable solar panel manufacturers claim they can charge laptops by connecting directly to the panel, it’s not a good idea. Voltage fluctuations can potentially damage devices, and portable solar panels are slower to charge devices than battery power packs. Not to mention, solar panels can only be utilized during daylight hours, while a combination of both (battery and panel) allows you to maximize power generation by using the battery in the evenings and recharging it on the panel during the day.

Why Trust Treehugger?

The author, Amber Nolan, lives off-grid (most of the year) on a houseboat using almost entirely solar power, but she also relies on the Jackery portable solar generator when she’s traveling.
