28W 4 Panel Solar Charger

Description

Reliable 28W Power Output

The NESTOUT 4-panel solar charger delivers up to 28 watts of output to charge smartphones, tablets, power banks, GPS units, and more. Built with high-efficiency SunPower MAXEON™ monocrystalline cells, it offers long-lasting solar performance for off-grid use, making it an ideal solution for camping, hiking, and emergency preparedness.

Compact & Lightweight

Weighing just 1.6 lbs (765g), the solar charger folds down to just 6.1 x 11.2 x 2 inches. The foldable design with reinforced seams, ripstop nylon, and water-resistant materials makes it easy to pack, carry, and deploy in rugged environments. An adjustable stand helps you angle the panel to optimize sunlight exposure throughout the day.

Heavy-Duty, Weather-Resistant Construction

Built for tough outdoor conditions, this rugged solar charger uses water-repellent 210D ripstop nylon, a transparent TPU panel layer, rubberized zipper pulls, and PVC backing to help resist dirt, moisture, stains, and rough handling.

Modular Integration with NESTOUT Power Banks

Pair the 4 Panel Solar Charger with any NESTOUT battery to create a portable, off-grid energy system. The built-in storage pouch is designed with elastic straps to securely hold a 15000mAh, 10000mAh, or two 5000mAh NESTOUT batteries, keeping your gear organized and protected while charging.

Charge your NESTOUT power bank during the day, store backup power for later, and stay powered when outlets are out of reach. For added protection in light rain or splash-prone conditions, pair your power bank with the CAP-1 Charging Cap to help shield the charging port during outdoor charging.

This integrated design lets you charge during the day, store power efficiently, and stay prepared wherever you adventure.

What can the NESTOUT 28w Panel Solar Charger charge?

NESTOUT solar chargers can charge a wide range of USB-powered devices using direct sunlight.

Compatible devices include:

How long does the NESTOUT 28W 4 Panel Solar Charger take to charge devices?

• 10000mAh battery: ~4 hours and 15 minutes
• 15000mAh battery: ~6 hours and 15 minutes
• Standard smartphone: ~4 hours and 30 minutes

Charging may take longer in partial sun or changing conditions, so we recommend fully charging your gear before heading out.

Is the 4 Panel Solar Panel waterproof?

The NESTOUT 4 Panel Solar Charger is water-resistant, not fully waterproof. It can handle light splashes and moisture from outdoor use, and the integrated storage pouch includes waterproof zippers to help protect small gear while charging.

Do not use the solar charger in heavy rain or submerge it in water. For the best long-term performance, avoid prolonged exposure to wet conditions.

How do I know if the NESTOUT 4 Panel Solar Charger is charging?

The built-in digital display shows real-time power output in watts, letting you confirm energy generation and optimize panel position.

How does the 4 Panel Solar Charger compare to the 2 Panel version?

Can I charge the 4 Panel Solar Charger while I’m hiking or moving?

Yes, The 4 Panel Solar Charger includes 6 attachment loops for mounting to your backpack or gear. However, charging is most efficient when stationary and positioned directly toward the sun.

Does the NESTOUT 4 Panel Solar Charger store power?

No. The solar charger does not store power by itself. It converts sunlight into charging power for USB-powered devices or compatible NESTOUT power banks. To store power for later, pair it with a NESTOUT power bank.
