[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.

My review is to help you with your choice when it comes to your expectations of what this product is capable of and delivers in regards to its use case and scenario etc. This solar panel works best one of two ways; perfectly flat on the ground during mid day. If it is not mid day your are going to have to prop it up on something to catch the angle of the sun. That means working against the design of the product as it's origami nature is floppy and will want to fall over close etc no matter how well you find something to prop it up against with it. This is a nightmare and you will be screaming. The second is actually using this with the included carabiners on a back pack. Handling it this way is the true second best way to use the product. And don't worry about oh will I be facing against the sun or something. In my life I've come to find that the sun for some reason is always behind me and never in front. So yes more than often it will be catching light by hanging off of your pack. Also expectations about wattage/output. I've owned two. The first one could output 12 Watts while my newer second one can only output 5 watts. While 5 watts is acceptable do keep that in mind. Also the C port doesn't have enough depth. It's like it's it can only accept 3/4 of the C connection. I don't recall this issue on my first unit. So depending on which one you get again my first one didn't do this will probably be falling out. So it's probably best to stick with the A port. All in all I'm pleased with my purchase(s) and am thankful for the back up and life giving opportunity this product has given me.

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 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.

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.

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.

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

Used on my himalayas hike to EBC. You cannot find quality solar panels like this in Kathmandu, circa 2026. Buy one before you get to Nepal, and you’ll have power for your cell phone even once you get to the higher villages where they start charging for power use. You won’t need it really until Loboche.

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
