As recently as a decade ago, no one would think twice about going backpacking without a cell phone. You’d leave it in a car at the trailhead, and answer any messages after you packed out. But with our increasingly connected lives, having 24/7 cell phone access is more and more important to people.
But what do you do when you’re on a weekend or weeklong trip? Even the most robust phone batteries will die after a couple of days, particularly if they’re in the backwoods, straining for a signal.
We’ve decided to find the best solar charger for backpacking, so you can stay juiced up both at home and in the woods.
In our search for the best backpacking solar charger, we’ve looked at large, high-powered models and smaller, more easily-portable models. We’ve also looked for the chargers with the biggest power supplies, so you can recharge while you’re hiking from campsite to campsite.

The RAVPower 15000mAh Solar Charger is a compact, 15,000mAh battery with a backup solar panel that provides 1 watt of power. As with other compact solar panels, this isn’t enough to power your phone, just enough to charge the battery pack.
On the other hand, this charger is an affordable solution, and it’s compact enough not to take up a lot of space in your back. It’s also waterproof, so you can leave it sitting out unattended in questionable weather, and it will be fine.
This RAVPower battery pack also features a built-in LED flashlight. This is a true survival flashlight with standard, strobe, and SOS functions to handle just about any emergency.
Pros
- Versatile
- Compact and portable
- Affordable
Cons
- Relatively low power
- Charges slowly on solar
If you want a portable power solution that’s small, lightweight, and cheap, this one is a good selection.

Bottom Line
As you can see, there are significant differences between different types of portable solar chargers. Some are 18 inches or more to a side when they’re open, and are made to charge several devices at once. Some are smaller and are designed to charge a portable power supply over the course of an entire day.
When choosing a charger, you ultimately need to answer three questions:
- How many devices do you need to charge?
- How much time are you spending hiking versus remaining at the campsite?
- How much bulk are you willing to add to your kit?
Depending on the answer to those questions, your needs are going to be different. You may even find that multiple smaller chargers are a better solution than a single large charger if you have several devices to charge and you aren’t spending many daylight hours in camp.
