  • Interesting thing
Model: 144A_01
Conditions: - Ukraine (central region). - Local time 11:00-12:00 (Jul 18 2022) - Bright sun. Was some clouds, but most of sky was clear. Tested only in clear and bright periods (peak of sun light) Results: - 20Ah Redmi (Power bank) - 5.03V x 1.27A (6.3881W) -- Best result - iPad mini - 4.88V x 0.87A (4.24W) - iPhone SE - 4.34V x 0.49A (2.1266W) - 10Ah Asus (Power bank) - 5.11V * 0.36A (1.8396W) In several testing found what result was depends on devices, so with panel all looks ok. Additional info: - 180g weight more than in description (weight 680g but according description should be 1.1 pounds (498.952g)). - Led changed color only with connected devices - Led not looks so informative as could be, because by usual usage will not be seen behind solar panel. It could be "pros" in war time, as it better masking of solar panel. But for non-military usage will be better to have some integrated LED to some edge (with possibility to disable feature with some switch) - That kind of foldable design eats more space in backpack as other possible variants which I saw, also need be careful with transportation (foldable edges looks not so strong on pressure) ... show more

  • Charges fast but heavier than advertised
Model: 144A_01
I’ve been geeking out on solar panel weights for the past few weeks. Finally settled on this one. I had a good watt to weight ratio. Unfortunately, it is a little heavier than advertised. They claim “1.3 pounds”, which is roughly 20.8oz. My scale reads 23.8 ounces of actual weight. Which is about 1.5 pounds (over 14% heavier). I’m not sure how many of the other solar manufacturers trim their claimed weights. Just be aware that this one’s a bit heavier. ... show more
