8 W Solar Panel: Mixed Results with Portable Solar Charger

The 8W Solar Panel with Solar Power Bank from WOWMVP that I recently purchased had me excited to test out its capabilities for charging my devices on-the-go.

I took the solar panel and power bank on a camping trip, hoping to rely on it for keeping my phone charged throughout the trip. However, upon testing it, I found that the charging capacity was not as efficient as I had hoped. A friend used it to charge her phone, which only managed to charge half of mine after her phone was practically full. Additionally, the design with plastic components made it prone to slipping on various surfaces, which was a slight inconvenience.
