GRECELL 100W Portable Solar Panel — Foldable Waterproof 20V Charger with Smart Chip & Anderson Connector

GRECELL's 100W Portable Solar Panel is a foldable, waterproof solar charger built to recharge power stations and portable generators with high-efficiency monocrystalline cells.

This compact bifold solar panel delivers up to 100 watts and 20 volts of clean sunlight conversion, and it includes multiple DC adapters plus an Anderson cable so it links easily to most portable power stations. The panel combines a rugged weather-resistant outer fabric, integrated kickstands for ideal sun angle, and a smart chip that optimizes and protects charging — all in a briefcase-like package designed for travel, RV use, camping, or emergency backup.

How fast will this panel charge my portable power station?

Charging speed depends on your power station's input limits and sunlight conditions, but the GRECELL 100W panel can deliver up to 100W under strong sun and supports series or parallel pairing to increase output. Its smart chip matches voltage and current to the attached device, helping maximize wattage while safeguarding against overload.

• Maximum output: ~100W and 20V under optimal sunlight.
• Smart chip regulates charging to prevent overcharge and overcurrent.
• Supports series/parallel connections to combine two panels for higher wattage.
• Includes multiple DC adapter sizes and Anderson connector for broad compatibility.

What connectors and compatibility does the GRECELL panel offer?

The panel ships with a selection of DC adapters (8mm, 5.5×2.5mm, 3.5×1.35mm, 5.5×2.1mm) and an Anderson cable so it can connect directly to many portable power stations and solar generators. That variety reduces the need for extra adapters and makes it ready for RV power stations, camping batteries, and common consumer generators.

• Included adapters cover most portable station input ports.
• Anderson cable supports higher current transfer (up to 25A max).
• Plug-and-play design minimizes setup time in the field.
• Works with both single-panel setups and paired configurations for more power.

How durable and weatherproof is the design for outdoor use?

GRECELL built this charger with waterproof Oxford cloth and ETFE-laminated monocrystalline cells to improve durability and resist dust, heat, and moisture. Reinforced grommets, a zippered accessory pocket, and sturdy kickstands let you mount or position the panel securely in campsites, on RV roofs, or near boats.

• Outer layer: waterproof Oxford fabric for outdoor resilience.
• ETFE lamination protects solar cells and improves longevity.
• Reinforced grommets for hanging or tie-down mounting.
• Kickstands for stable, adjustable placement on flat surfaces.

Can I carry this panel easily during travel or storage?

The bifold layout folds into a compact, briefcase-like package with a built-in zippered pouch for adapters, making it simple to stow in car trunks, RV storage, or carry by hand. Its lightweight construction prioritizes portability without sacrificing protective layers and mounting features.

• Folds flat into a compact carrying shape for transport.
• Zippered pocket stores adapters and cables neatly.
• Lightweight materials reduce pack burden during trips.
• Built-in handle and slim profile fit into small storage spaces.

Who is this for? The GRECELL 100W Portable Solar Panel is aimed at RV owners, campers, vanlifers, weekend adventurers, and anyone who needs a compact renewable charging solution for portable power stations. It also fits households wanting a reliable, travel-ready backup for small generators during outages or off-grid use where a durable, easy-to-connect solar charger speeds recovery of battery power.
