[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

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

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.

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.

This product works very well on sunny days. It does what I bought it for. 👍

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)

Immediately used this on a four day backpack trip and it performed very well. Had weather every day but enough sunshine midday to recharge my iphone, inreach mini and another phone.

So the name of this solar panel is P25 and right in the title it says "25W" but do not be fooled that you will ever get 25 watts out of a single port. Its right on the box, maximum wattage from the USB-A port is only 12 watts and the USB-C port is only 15 watts max. Big Blue decided to add these together to make you think this can pump out 25 watts, which in perfect conditions perhaps it could give you the 12 + 15 watts but I've never seen that. In reality, using a solar panel alignment tool and the sunny skys in August in the midwest, I can only get 9-10 watts out of the USB-C port. USB-A port is 8 watts. If I plug an Iphone in the USB-A and an Ipad Mini into the USB-C port, the iphone charges but the ipad displays "Not charging" meaning the USB-C port doesn't have enough power output to even be considered a charger with two devices hooked up. If I charge the ipad by itself, it does charge. This is a pretty weak product for the price and should only be considered a 10'ish watt charger. You need to really value the compactness of this to pay this much.

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.
