BigBlue 60W Foldable ETFE Solar Charger 【IP68 Waterproof& Angle Stand】 | Portable Solar Panel QC3.0+PD45W+22.2V DC Output for Power Emergency Camping, Compatible with Smartphone Tablet Power Station

I use it camping to charge a power bank, and mobile phone. Over ten days it coped admirably. Where I was camping the sun hit my tent from 2pm onwards, the sun hitting the panel at 90' at 3pm. The panel was not moved to track the sun, and in two hours of bright, but cloudy skies, always charged both, fully. In full midday sun it spits out 1.3 amps, at 8 volts, making over 10 watts of power; but we don't always get full sunshine ! I lean it against my tent wall, and put two pegs through the bottom corner holes; it never moved in wind. At a push, with less tree cover, I reckon the equivalent of four mobiles could be handled. The power bank seems unaffected by varying voltages, so that is plugged direct to the panel. Not sure an "i" phone is so obliging, so that is connected to the power bank output, stabilised at 5V. You need more leads than are provided, and one long one, depending on tent size/sun orientation.

No water damage, not dropped, handled with care.

I really wanted to like this one. Looking forward to a small N type panel. It's got great connections and a solid cable with an xt60 adapter. Unfortunately, it never performed from day 1. I have a 100w panel when sunlight was poor I would get 1-5watts. On this it will struggle to get 1 watt. Admittedly, surface area is roughly 20% less. But in the same location with the same sunlight I wouldve expected better performance. In strong sunlight, while I would get 50-60w on the 100w panel. I would get roughly, 30-40w on this (closer to 30w most times). So not bad. I find that acceptable. It gradually got worse, it started getting lower day by day. Tried with different cables and power banks. Never achieved the highest wattage. Folded it up gently every day, like I would with my other panels. Now it's completely failed. Its interesting, I was sent this in its original box. My address label was just added on. There was no tamper tape on it at all. Anyone could basically open the box. A real shame. Pretty dissappointing. Needed a compact and reliable travel panel. *update* its charging again. I think the panels are fine. Only works reliably on DC port. Pulling 30-40w. The USB C/a have both failed.
