35W Sunpower Portable Solar Panel
I’ve been eyeing a portable solar charger for some time now, mainly for camping and emergency backup use. This 35W Sunpower Portable Solar Panel caught my attention because of its compact foldable design, USB output, and the promise of a stabilized charge — all at a much lower price than anything comparable in the US.
Why I Bought It: I wanted a lightweight, reliable solar panel that could charge phones and power banks during hikes and road trips. Most US versions are priced well over $80, and this one was under $40, which seemed like a steal.
Using It: Out of the box, I was impressed. The panel is very thin, folds easily, and the USB port is well-secured. I tested it on a partly cloudy day — it charged my iPhone 13 Pro from 20% to 80% in about 1.5 hours. In direct sunlight, the efficiency was even better.
Pros: Lightweight, easy to carry, effective charging speed, affordable. Cons: No built-in battery (not a dealbreaker for me), the fabric edges feel a bit flimsy.
Price Comparison: In the US, something similar from brands like Goal Zero or Anker costs 2–3 times more.
Expectation Check: Honestly, it exceeded my expectations in both build and performance.
