60W 19.8V Foldable Solar Panel Kit,Monocrystalline Solar Cell Solar Charger with USB Outputs and 4-in-1 Connector for Smartphones, Tablets, Laptops, and Power Stations

Excellent. I bought this as it's not just more affordable but more compact than other solar panels. I connected mine to the Anker 521 (256Wh) and it was plug and play. The photos show it has the correct connection and show i am getting ~43 Watts in 90% sun (at end of August). Based on this rate, 28% charge is (and was) achievable on 1.5hrs. Excellent size:power ratio

I have 2 of these now. They seem to work well. I have one in the car to charge stuff up whilst I am out in the countryside. Chucked it on the roof of the car and attached the phone and it started to charge up straight away. Going to try charging my little Jackory unit next...

Before I say anything else: I'm very happy with the product, but there is some room for improvement. The panel does what it says. It's a solar panel you can fold up and fit into your backpack. On a good day, it will hit the 60W rating and I have even managed to get it to (very slightly) exceed that rating by pointing it directly at the sun and using an MPPT charger on the direct DC output. When the weather plays along, the built-in USB ports work well, and it's plenty to charge a power bank or keep several small devices running indefinitely. It can even power a laptop under moderate load. Due to the foldable design, it's difficult to keep pointed at the sun, and laying it flat on the ground inherently limits its power output. It also feels a bit fragile - even just while folding it back up I've occasionally heard a little "crack". This doesn't seem to have affected its power output yet, and there's no damage as far as I can tell, but it certainly doesn't inspire confidence. Any clouds will drastically reduce the power output to the point where the USB ports become unreliable (they'll cut in & out every few seconds). Using the direct DC output with an external MPPT device works more reliably.

Brilliant, regularly pulls in more than its meant to. Delighted with it ☀️. Had it a year & used loads, charges my ecoflow or can charge the ipad & iphone just sitting out on the car window. Perfect for camping

Great bit of kit, works great and folds down nice and compact when not in use

Produced a peak of 78w In direct sunlight... very impressed but would definitely reccomend a higher wattage once you get anything more than a basic powerstation (as seen here).... Will be getting a higher wattage in future for my new 2kwh ecoflow....

Amazing

Folds like a briefcase opens up well but outputs only about 30watts no way near the 60w
