Ultra-Light 21W Portable Solar Charger, BigBlue Foldable Solar Panel Charger with USB-A and USB-C (5V/4.2A Toal), IP68 Waterproof for Camping, Emergency Power, Compatible with Phone, Power Bank etc.

Great solar panel. Kept all my devices charged easily on expedition in Pakistan. It’s rugged and well made.

I am very happy with what I got! It works amazing in good weather. I didn't even position it and tilted it according to the sun (was on the beach, midday, so...). But even under some clouds it was doing ~10-15% battery charge per 30-35 mins. Made sturdy and can be placed almost anywhere. Charging more than 1 device slows it down. Could it be better - may be, I don't know. I am not in a rush and will never be in a rush in places where I will need to use that (Beach, hiking, terrace at home). I am VERY happy with this purchase! :)

Its good, it charges, I bought it to charge the jackery & it works, obviously slower than home voltage but yes, it works

Rubbish!!! The charging times are no way near as stated and you definitely can not charge 2 things at once. My Ring camera battery has been on charge for over 24 hours now and is still not fully charged, just plugged my EarPods in and it basically crashed. Don’t waste your money… shame!

I purchased this by chance, the week before a major storm and 3 day power outage. It was really useful for keeping the phones charged and easily positioned to where the sun was shining brightest. Super happy with this impulse purchase at a very reasonable cost.

It took around a day to charge my phone (S24) from 0 to 100% in full summer sunlight, but hey, it was free energy so I'm not complaining.

Très bon fonctionnement nickel à acheter

material seems good. fast charging under full sun.

Erster Eindruck (SolarPowa 30): Saubere Verpackung mit detailliertem Beschrieb auf der Rückseite. Gut gepolstert, jedoch wurden die 2 Karabiner mit dem kurzen USB-C Kabel lose in die Verpackung gelegt. Sieht wertig und stabil aus, genau wie erwartet :) Gute Grösse und Gewicht. Jetzt muss nur noch die Umwandlung der Sonnenenergie getestet werden! Bis jetzt sehr zufrieden. Wurde auch pünktlich geliefert. Nachtrag/Update vom Balkon 06-04-2025: - kleine Beule im Sonnenlicht entdeckt - trockener Klebstoff bei einer Öse entdeckt - Positiv: es wird mit Quick Charge geladen, ohne das Panel ganz korrekt zur Sonne hin auszurichten (kontinuierliche 16 Watt zeigt das Ladekabel an) um 14:30

Perfect for charging the big 20,000ah battery and large amp devices and works decently in low light conditions, automatically restarts after interruptions
