[Upgraded] BigBlue Ultra-Light Portable 25W Solar Panel Charger with USB-A and USB-C Ports, 0.84 lbs Pocket-Size IP68 Waterproof, Folded Solar Panel Compatible with Cellphone,Power Bank,Camping Light

The BigBlue 25W upgraded solar panel system itself is honestly great. It charges reliably, folds up nicely, feels durable, and performs well outdoors. For hiking, camping, or emergency backup power, I’d absolutely recommend the actual product. It’s lightweight and efficient, and the panel quality seems solid. That said, Amazon seriously needs to get control of its returned-item reselling situation. My box arrived missing 2 carabiners and 1 USB-C cable. Of course, the manufacturer wants you to use their specific cable setup, so that was pretty frustrating right out of the gate. This clearly looked like a returned item that was restocked without anyone actually checking the contents. That’s not really on BigBlue — the product itself is excellent — but Amazon’s warehouse quality control is slipping hard lately. So: 5 stars for the panel system. Maybe 2 stars for Amazon fulfillment roulette. Double-check your box contents when it arrives.

Works as advertised. I have used this on several backpacking trips so far. Recharges my small battery pack quickly.

Size is good but the marketing is deceptive. While it may my 25W worth of solar panels you can't get 25W out of either port or as total output. Right on the back of the unit the outputs are printed and the highest port is the C port at 15W (5V x 3A). It's lists total output as 5V 4A which is 20W between both ports at once. In practice this is a 15W unit because that's the most you can get from one port and that's a bit disappointing compared to the advertisement at 25W. Otherwise it seems to be made well enough and while the wattage is low for what I wanted it'll work.

folds into small package, well made. Charged a 10,000 portable power bank in about 6 hours in the sun. Great back up item and small and lite. Highly recommend. Very well made, wish it came in a small case, has an elastic strap to hold it closed, but very happy with it overall

This is the most compact folding panel I've ever seen. Very small, but provides 25W of power, sufficient to recharge my phone, my tablet, and virtually any other mobile device I own, including power banks. Perfect for keeping in the car for emergencies or for hiking.

This thing is great. I charge my phone and battery packs on it. Even on cloudy days it still charges. In full sun in L.A. it took about two hours to charge a 5000 mah battery. I might buy another just to keep in my truck.

The build quality and form factor are great. Light and compact. I love that. The panel may be 25W, but it delivers the power slowly. Would be good probably for something that doesn’t need to be charged quickly. While using it with my phone plugged in in direct sunlight on a 90 degree day, my phone still loses charge while plugged in.

I took this backpacking and it worked pretty well. READ THE DESCRIPTION BEFORE USING IT! If there’s an inconsistent light, it will drain your battery more than charging it, so when I had it on my backpack to charge my phone, I couldn’t understand why my phone was just not charging! When I got back, I read the instructions. Overall, it wasn’t what I needed. I should have gotten a more powerful model. But I didn’t know. Not the product’s fault, and I’ll definitely still use it, but if you’re going backpacking, my advice is not to skimp on this piece of equipment. (Sorry for the photo from Instagram stories - it’s the only one I have)

Although less output than advertised it performs competitively to other foldable small solar panels. Its key advantage is in the compactness it offers for backcountry camping. Keeps the small power bank, phone, Inreach, GPS /watch units charged easily with a couple of hours with good, bright sunlight.

Ich habe mir die Solarplatte zusammen mit einem Akku für meinen Bulli gekauft. Sie funktioniert einwandfrei. Als Kritikpunkt lässt sich nur die kurze Kabellänge nennen, wodurch ich dazu gezwungen war, mir ein Verlängerungskabel anzulegen. Sehr positiv finde ich die kompakte Größe im gefalteten Zusagen, sowie die vielen Anschlussmöglichkeiten

Most foldable panels are bottlenecked by the types of connector you attach to the panel. E.g if you buy a 60w panel with only two USB connectors you can only pull 5 watts out on each port. In the case of this solar panel, it supports USB PD and can deliver 60w out through that port and less concurrently through the other ports. Even in cloudy conditions, the panel has easily delivered 30watts to a Li-on battery via the USB-PD port. I’m also delighted that most the of the panel is entirely waterproof - you just need to shield the connector box from water (excellent for camping). Overall, a worthy investment and a significant step forward from previous technologies.

Pannello solare ottimo, di livello quasi professionale, unisce grande potenza ad una grande semplicità di utilizzo grazie al supporto delle più attuali tecnologie di ricarica usb e grande versatilità grazie al fatto che è pieghevole in 12 parti e di dimensioni abbastanza contenute in rapporto alla potenza di 100 watt. Anche il peso di 4 kg non è eccessivo in rapporto alla potenza ed è leggermente inferiore alla media dei prodotti dello stesso livello. Quello che sorprende è il potenziale veramente elevato che è difficile sfruttare a pieno perché è difficile trovare delle batterie che supportino una velocità di ricarica altrettanto elevata. È possibile ricaricare fino a 4 batterie contemporaneamente, io lo uso con una power station da 41200 mah e con 3 power bank di varie dimensioni e in condizioni di sole pieno ricarica tutto in meno di mezza giornata. In particolare se collego la power station Litionite Riden da 41200 mah al connettore Power Delivery con un cavo usb type-c compatibile con la ricarica a 100 watt, in condizioni ottimali, si ricarica da zero al 100% in meno di 3 ore ! Queste caratteristiche secondo me giustificano il prezzo un poco più alto rispetto altri prodotti simili.

Good
