Outdoor Gear Lab found that the FlexSolar 60W generates over 5,100 mAh per hour via USB-C in direct sunlight, while The Camping Nerd noted its versatile junction box supports DC and multiple device charging. However, it weighs approximately 6.4 lbs, which reduces portability for ultralight backpacking compared to smaller competitors. The cloth exterior also attracts dust more easily than molded plastic alternatives, requiring regular cleaning to maintain efficiency. This model fits car campers needing high output and extensive accessories, but hikers should look elsewhere due to its significant weight.

Strengths
  • — Outperforms lower-wattage competitors in direct sunlight, generating over 5,100 mAh per hour via USB-C according to Outdoor Gear Lab.
  • — Includes a versatile junction box with DC (20-28V), USB-C PD (60W), and dual USB-A ports for charging power stations and multiple devices simultaneously.
  • — Comes with extensive accessories including a 10 ft DC cable, four DC adapters, and alligator clamps for immediate use with various power stations.
Watch-outs
  • — Weighs significantly more (approx. 40 oz to 6.4 lbs) than smaller competitors, reducing portability for ultralight backpacking.
  • — Cloth exterior material tends to attract dust and dirt more easily than molded plastic alternatives.
Oupes 100W Portable Solar Panel
Ranked #7 in Best Portable Solar Panels
Oupes 100W Portable Solar Panel
2 sourcesall derived$153as of Oct 2

Survival Living found that this four-panel unit offers exceptional setup simplicity and portability, weighing just four pounds and folding compactly into a case with Velcro straps. The barrel plug connection provides easy integration for compatible OUPES power stations, though Mike Tango Whiskey noted that this proprietary interface restricts users to the brand’s ecosystem rather than allowing universal third-party panel compatibility. The 100W output serves primarily as a slow trickle charger or emergency top-up for small electronics like phones and lights, requiring significant direct sunlight exposure to generate meaningful power. This model fits vehicle campers and preppers seeking low-maintenance backup energy but is unsuitable for backpacking due to its bulk or for users needing rapid charging of large battery banks.

Strengths
  • — Foldable design features four panels held together by Velcro for easy setup and packing.
  • — Includes a dedicated carrying pouch with a handle, weighing approximately 4 lbs.
  • — Connects via a simple barrel plug that plugs directly into compatible OUPES power stations.
Watch-outs
  • — Barrel plug connection is proprietary to specific OUPES models and not universal across all solar generators.
  • — 100W output is low relative to larger power stations, requiring significant sun exposure for meaningful charging.

How they stack up

FlexSolar 60W

The FlexSolar 60W includes extensive accessories like DC cables and adapters out of the box, whereas the Bluetti PV350 relies on a long integrated MC4 cable but lacks additional hardware. While both offer good direct-sun performance, the FlexSolar 60W is heavier than the compact FlexSolar 40W, reducing its appeal for those prioritizing minimal pack weight.

Oupes 100W Portable Solar Panel

The Oupes 100W Portable Solar Panel uses a proprietary barrel plug connection, which restricts compatibility to specific OUPES models unlike the universal MC4 connectors on the Bluetti PV350 and Renogy 200W. It is lighter than the Jackery SolarSaga 200 but offers lower wattage, making it better for small electronics than large battery banks.
