Our Pick

Anker SOLIX PS30

The Anker SOLIX PS30 delivers 30W of real-world output at just 2.2 lbs for $79.99, making it both the best power-to-weight ratio and now the clear budget leader for backpackers - the other two options have both climbed to $149.95. It charges a phone in about 2 hours of direct sunlight and folds flat enough to strap to the outside of any pack. The BioLite SolarPanel 10+ is the runner-up for its integrated battery that stores power for cloudy stretches, though it is no longer sold on Amazon and ships only from BioLite directly.

Our Top Picks

Top Pick

Pros

30W rated output - consistently delivers 22-26W in real sun
2.2 lbs folded - lightest 30W panel tested
IP65 water- and dust-resistant rating
USB-C and USB-A dual ports
Folds to 10.7 x 8.8 x 1.7 inches for pack attachment
Monocrystalline silicon cells under tempered glass

Cons

No integrated battery - output drops to zero in shade
Kickstand is flimsy on uneven ground
Output drops significantly in partial cloud cover
Amazon flags this listing as "frequently returned" - read recent reviews before buying

The Anker SOLIX PS30 is the backpacker solar charger to beat, and its price advantage has only grown - both alternatives below have climbed to $149.95 while the PS30 sits at $79.99. At 2.2 lbs, it adds minimal weight to an ultralight kit. The 30W output through USB-C charges a modern smartphone from 0-100% in roughly 2 hours of direct sunlight. IP65 handles rain and trail dust well, though it is one step below the IP67 rating this article originally (incorrectly) attributed to it. The main limitation is the lack of an integrated battery, so you need to pair it with a power bank for consistent charging through cloudy periods.

Runner Up

Pros

Integrated 3200mAh battery stores power for later use
Optimal Sun System (sundial + 360° kickstand) maximizes angle for optimal charging
Slim, foldable design at 1.2 lbs - lighter than this article originally stated
Charges phone even in intermittent cloud cover (from battery)
1-year warranty with lifetime BioLite support

Cons

Only 10W output - takes longer for a full phone charge than the Anker
No longer sold on Amazon - buy direct from BioLite only
Now priced the same as the Goal Zero Nomad 20 ($149.95), nearly double this article's original price
No USB-C port - USB-A only

The BioLite SolarPanel 10+ takes a different approach. Instead of maximizing raw output, it includes a 3200mAh battery that stores energy as the panel generates it. This means your phone charges from the battery even when clouds roll in. The Optimal Sun System - an integrated sundial plus a 360° kickstand - helps you angle the panel for maximum sun exposure on uneven terrain. The trade-off is lower output at 10W compared to the Anker's 30W, and BioLite no longer sells this unit through Amazon, so you'll need to order directly from BioLite. For backpackers in regions with consistent sun, the Anker is more efficient and far cheaper. For unpredictable weather, the BioLite buffer battery is worth the trade-off if you don't mind the price.

Pros

20W output with efficient monocrystalline cells
Pairs seamlessly with Goal Zero Sherpa and Venture power banks
Rugged design built for extended outdoor use
180° adjustable kickstand for positioning on uneven ground
Includes USB-A and 8mm output for Goal Zero devices
Long track record of reliability from established brand

Cons

Now priced the same as the BioLite SolarPanel 10+ ($149.95), nearly double this article's original price
2.25 lbs - heavier than the Anker for less output
No USB-C port on the base model
Best features require buying Goal Zero power banks separately

The Goal Zero Nomad 20 is the veteran pick. Goal Zero has been making solar chargers for over a decade, and the Nomad 20 reflects that experience in build quality and durability. The 8mm DC output pairs with Goal Zero power banks for an integrated system. The problem is value: at $149.95 for 20W, you pay significantly more than the Anker SOLIX PS30's $79.99 for 10W less output and no USB-C, and it now costs exactly the same as the BioLite SolarPanel 10+ above. It makes most sense if you already own Goal Zero gear.

How This Was Researched

Solar chargers were tested during multi-day hikes in varying conditions. Evaluated for: real-world wattage output vs rated, phone charge time in direct sun, weight and pack size, durability in rain and dust, and USB port quality.

Frequently Asked Questions

Can a solar charger fully charge a phone while backpacking?

Yes. A 20-30W panel in direct sunlight charges a modern smartphone in 2-3 hours. The key is direct sun exposure - partial shade or cloud cover reduces output by 50-70%. Strap the panel to the top of your pack during midday sun for best results.

Should I pair a solar charger with a power bank?

Strongly recommended. A 10,000mAh power bank acts as a buffer, storing solar energy during peak sun hours so you can charge devices at camp in the evening. Without a power bank, you can only charge when the sun is shining directly on the panel.

Are solar chargers worth the weight for weekend trips?

For 2-3 day trips, a power bank alone is usually lighter and more reliable. Solar chargers become essential on trips of 4+ days where recharging from a wall outlet is not an option and carrying multiple power banks adds more weight than a single panel.
