Our Pick

Anker SOLIX PS30

The Anker SOLIX PS30 delivers 30W of real-world output at just 2.3 lbs, making it the best power-to-weight ratio for backpackers. 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.

Our Top Picks

Top Pick

Pros

30W rated output - consistently delivers 22-26W in real sun
2.3 lbs folded - lightest 30W panel tested
IP67 waterproof and dustproof rating
USB-C (30W PD) and USB-A dual ports
Folds flat to 11 x 6.5 inches for pack attachment
Durable ETFE coating over monocrystalline cells

Cons

No integrated battery - output drops to zero in shade
Kickstand is flimsy on uneven ground
Output drops significantly in partial cloud cover

The Anker SOLIX PS30 is the backpacker solar charger to beat. At 2.3 lbs, it adds minimal weight to an ultralight kit. The 30W output through USB-C PD charges a modern smartphone from 0-100% in roughly 2 hours of direct sunlight. IP67 means rain and trail dust are non-issues. The ETFE-coated monocrystalline cells are more efficient than the polycrystalline panels found on cheaper chargers. 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
Sundial alignment tool maximizes angle for optimal charging
Slim, rigid design clips directly to backpack exterior
Charges phone even in intermittent cloud cover (from battery)
USB-A output with charge indicator lights
Durable and well-built - no flimsy folding panels

Cons

Only 10W output - takes 3-4 hours for a full phone charge
1.54 lbs for just 10W is less efficient than the Anker
3200mAh battery only holds about 70% of one phone charge
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 sundial alignment tool is a clever touch that helps you angle the panel for maximum sun exposure. The trade-off is lower output at 10W compared to the Anker 30W. For backpackers in regions with consistent sun, the Anker is more efficient. For unpredictable weather, the BioLite buffer battery is worth the trade-off.

Pros

20W output with efficient monocrystalline cells
Pairs seamlessly with Goal Zero Sherpa and Venture power banks
Rugged design built for extended outdoor use
Foldable four-panel design distributes weight evenly on a pack
Includes USB-A and 8mm output for Goal Zero devices
Long track record of reliability from established brand

Cons

$99 is the most expensive option for mid-range output
2.4 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 four-panel foldable design is well-balanced on a pack. The 8mm DC output pairs with Goal Zero power banks for an integrated system. The problem is value: at $99 for 20W, you pay $40 more than the Anker SOLIX PS30 for 10W less output and no USB-C. It makes most sense if you already own Goal Zero gear.

How This Was Tested

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.
