Best Portable Solar Power Generator In 2026 - OUPES

All solar power generators have a 5-year warranty. you can get a FREE 1-year warranty extension after warranty registration.

Most of the solar panels on the market are compatible, but you need to check whether the specifications and plug are matched (Within 150V, and the connection port is Anderson), you also can feel free to contact us via email before connecting them.

Actually, we suggest customers connect the OUPES solar panel with the OUPES solar power generator, as there is already a solution provided in the generator and also the third-party solar panel.

Different companies' solutions may conflict, causing charging not to be done as efficiently as desired although they are universal.

We have waterproof treatment for solar panels, but I do not recommend you use them in the rain. Portable solar panels cannot be fully waterproofed like hard solar panels. Long-term exposure to rain may reduce cell efficiency. The length of the solar charging cable is 16ft long. We also provide the extensions on the website. Please note that the charging efficiency may be reduced due to the charging cable being prolonged. It might require more time to finish charging with extension cables.

1. Maintain the battery at a charge level between 60% and 80% of its rated capacity. It is recommended to check and recharge the battery every 3 months to keep it within this range.

2. Store the battery in a dry and cool environment with a temperature range of 0 ℃ to 40 ℃ (32 ℉ to 104 ℉).

3. Ensure the storage area has a humidity level between 0% and 60%.

4. Avoid exposing the battery to corrosive substances, as they can damage the battery's integrity and performance.

5. Keep the battery away from fire hazards and heat sources to prevent potential damage or overheating.

By adhering to these guidelines, you can help preserve the battery's condition and extend its overall lifespan during extended periods of inactivity.
